<p>Optical recording of material cultural heritage (CH) is a multidisciplinary activity where the understanding of cross-disciplinary semantics is vital for a successful completion. In many cases, a lack of understanding of transdisciplinary semantics slows this process down. The end users who are mostly humanities experts lack the technical knowledge of spatial and spectral recording and could therefore demand more than what is actually required or sufficient for the intended CH application. The negotiations between technical experts and the end users are a tedious process. We present a semantic-based decision support system, COSCH<sup>KR</sup>, that employs reasoning and recommends optimal recording technology(ies) according to the application requirements of the recorded and processed data. COSCH<sup>KR</sup> is an ontology-based knowledge model that implies the development of semantic technologies within the Semantic Web framework. It represents formalized knowledge of the disciplines involved in the process of optical recording of material CH. The paper describes the applicability of the model in spatial, spectral, and visualization applications and summarises current possibilities and challenges.</p>

gis.Science
<p><span style="color: rgb(73, 72, 72); font-family: Roboto, Roboto, &quot;Helvetica Neue&quot;, sans-serif; font-size: 14px; text-align: justify;">Experts&rsquo; knowledge about optical technologies for spatial and spectral recording is logically structured and stored in an ontology-based knowledge representation with the aim to provide objective recommendations for recording strategies. Besides operational functionalities and technical parameters such as measurement principles, instruments, and setups further factors such as the targeted application, data, physical characteristics of the object, and external influences are considered creating a holistic view on spectral and spatial recording strategies. Through this approach impacting factors on the technologies and generated data are identified. Semantic technologies allow to flexibly store this knowledge in a hierarchical class structure with dependencies, interrelations and description logic statements. Through an inference system the knowledge can be retrieved adapted to individual needs.</span></p>

Terrain difficulty as a relevant proxy for objectifying mobility patterns and economic behaviour in the Aurignacian of the Middle Danube region: the case of Stratzing (Austria)

2017

The Exploitation of Raw Materials in Prehistory: Sourcing, Processing and Distribution
<p>This paper addresses the factors that conditioned the choices in lithic resource procurement for tool making at the Late Aurignacian site of Stratzing-Galgenberg (Austria), based on the lithic assemblage from the main area of the site. The raw materials used in the analysed assemblage are varied and partly relate to various local and non-local proveniences. The importance of non-local flint in the assemblage contradicts the distance decay model according to which the amount of a given raw material decreases with the increasing distance from its source. Drawing on the approach developed recently by Lucy Wilson, we examine the predictive ability of &ldquo;source attractiveness&rdquo; with respect to terrain difficulty and energy expenditure to understand why some sources were used more than others, using a Geographic Information System (GIS). Our results indicate that terrain difficulty and mobility costs matter and have a better predictive ability than Euclidean distance alone to explain assemblage variability in the Aurignacian of the Middle Danube region.</p>

Virtual Archaeology Review
<p>The Château de Germolles is one of the rare palaces in France dating from the 14 th century. The noble floor is decorated with wall paintings that are a unique example of courtly love spirit that infused the princely courts of the time. After being concealed sometime in the 19 th century, the paintings were rediscovered and uncovered in the middle of the 20 th century and partly restored at the end of the 1990s. No scientific documentation accompanied these interventions and important questions, such as the level of authenticity of the mural decorations and the original painting technique(s) used in the medieval times remained unanswered. The combined scientific and financial supports of COSCH COST Action and DRAC-Burgundy enabled to study Germolles&#39; wall paintings using some of the most innovative imaging and analytical techniques and to address some of the questions raised. The study provided significant information on the material used in the medieval times and on the conservation condition of the paintings. The data collected is vast and varied and exposed the owners of the property to the challenges of data management.</p>

Development of a platform recommending 3D and spectral digitisation strategies.

2016

S Wefers, A Karmacharya, F Boochs

Virtual Archaeology Review
<p>Spatial and spectral recording of cultural heritage objects is a complex task including data acquisition, processing and analysis involving different technical disciplines. Additionally, the development of a suitable digitisation strategy satisfying the expectations of the humanities experts needs an interdisciplinary dialogue often suffering from misunderstanding and knowledge gaps on both the technical and humanities sides. Through a concerted discussion, experts from the cultural heritage and technical domains currently develop a so-called COSCH KR (Colour and Space in Cultural Heritage Knowledge Representation) platform that will give recommendations for spatial and spectral recording strategies adapted to the needs of the cultural heritage application. The platform will make use of an ontology through which the relevant parameters of the different domains involved in the recording, processing, analysis, and dissemination of cultural heritage objects are hierarchically structured and related through rule-based dependencies. Background and basis for this ontology is the fact that a deterministic relation exists between (1) the requirements of a cultural heritage application on spatial, spectral, as well as visual digital information of a cultural heritage object which itself has concrete physical characteristics and (2) the technical possibilities of the spectral and spatial recording devices. Through a case study which deals with the deformation analysis of wooden samples of cultural heritage artefacts, this deterministic relationship is illustrated explaining the overall structure and development of the ontology. The aim of the COSCH KR platform is to support cultural heritage experts finding the best suitable recording strategy for their often unique physical cultural heritage object and research question. The platform will support them and will make them aware of the relevant parameters and limitations of the recording strategy with respect to the characteristics of the cultural heritage object, external influences, application, recording devices, and data.</p>

<p>Cultural Heritage (CH) visualisations have to be understood as a combination of research sources, the contemporary historical and cultural context (Zeitgeist), project background and work process. All available information is collected, consolidated, filtered and assembled into a coherent picture. In case of digital 3D reconstructed models, the result is a digital data set that can be processed for different application fields. They are understood as a result of a complex creative process and as a synthesis of a CH research project, its CH context, the available research source material, and the modeling process itself. For all visualisation types in CH different conditions, factors, and basic rules apply to achieve a high quality result. Two examples are presented illustrating the structured view on visualisation projects as such. This paper seeks to differentiate the various research sources being the basis for digital 3D reconstructed models and defines work phases allowing a quality assessment. Furthermore, the potentials of including this structured view into the ontology COSCHKR currently under development is discussed. In combindation with traditional guidelines COSCHKR platform could open up new and flexible approaches.</p>

<p>The workshop and milling complex in Terrace House 2 comprises seven mills and one stone-sawing machine. Each were powered by a waterwheel. Based on the different features, it is possible to identify three building phases. The first comprised at least two mills powered by two independent waterwheels. The second had at least one mill. In the third phase five waterwheels drove four mills and one stone-sawing machine. In addition, it is possible to distinguish between two different types of waterwheel constructions.</p>

The Labelling System: A Bottom-up Approach for Enriched Vocabularies in the Humanities

Thiery, F., Thomas Engel

43rd Annual Conference on Computer Applications and Quantitative Methods in Archaeology, CAA 2015
<p>Shared thesauri of concepts are increasingly used in the process of data modelling and annotating resources in the Semantic Web. This growing family of linked data resources follows a top-down principle. In contrast, the Labeling System follows a bottom-up approach, enabling scientists working in the digital humanities to manage, create and publish their own controlled vocabularies in SKOS (Simple Knowledge Organization System). The created concepts can then be interlinked with well-known LOD (Linked Open Data) resources, a process named the &lsquo;Labeling Approach&rsquo;. The Labeling System is domain independent, while uniting perspectives of different scientific disciplines on the same label and therefore contributing to interdisciplinary collaboration for building up cross and inter-domain linked data communities. This paper addresses principles of the Labeling System in the light of archaeological use cases.</p>

<p>From autumn 2010 to spring 2013 the German Archaeological Institute and the Swiss Institute for Architectural and Archaeological Research on Ancient Egypt continued the investigation of the city and temples of Elephantine (Aswan). The preliminary report presents the results of some of the projects conducted during this period.<br />As part of the ongoing rehabilitation work at the museum buildings located on the island of Elephantine, excavations were conducted near the northeastern limit of the ancient town. Among the earliest remains found in the area is a well preserved section of the city wall of the late 2nd dynasty. Outside the perimeter of this wall Nile sediments dating to the Old Kingdom were identified, as well as settlement remains of the 6th to 12th dynasties. Several pottery kilns of the early Middle Kingdom were discovered here. A later city wall appears to have been constructed during the reign of Senwosret III and it seems to have existed until the early New Kingdom.<br />The documentation and study of the relief blocks originating from the Khnum temple of the New Kingdom was continued. Many of the blocks can be attributed to the temple house, the courtyard and the first pylon built by Thutmosis III, as well as to the festival courtyard which was added by Amenophis II. Some of the blocks appear to originate from other, so far unknown buildings of the temple complex, including a cult building of Thutmosis I and II, a barque station of Hatshepsut and a construction of Thutmosis IV.<br />The aim of another project has been the investigation of workshop areas of the Late Antique Period. During the excavation of a house dating to the 5th&ndash;9th centuries AD, evidence for the baking of bread, the keeping of animals and the production of granodiorite bowls has been found. Nearby an oven used for smelting non-ferrous metal was identified. Fragments of melting pots, casting molds and slag provide information on the production process.</p>

<p>Application and analysis capabilities of 3D data sets generated through UAV photogrammetry are presented on the basis of an exemplary millstone quarry of the so-called Mayen quarry district (Germany). In general, millstone quarries are technical cultural heritage sites which give evidence for economic interpretations as they are of interest for the reconstruction of ancient procurement patterns. Particularly those quarries which had a high economic impact cover large areas with often arduous accessibility. Therefore, photogrammetric recording using a UAV is the best approach for fast and inexpensive high-quality documentation. The images are used to create a 3D data set and orthophoto. For analysis and interpretation the Spatial Image analysis and Visualisation Tool (SIVT) of i3mainz is used allowing a variety of interactive visualization functionalities. The 3D data are transformed into 2.5D data enabling segmentation of spatial information and volume calculations. Both functionalities support the cultural heritage expert&#39;s research: On the one hand the interactive segmentation allows producing a map of the quarry displaying only those parts associated with the extraction. On the other hand the output of the quarry including debris and millstone blanks can be calculated easily. All in all, the entire workflow beginning with data capture using a UAV followed by data processing, (2.5D / 3D) data analyses and visualisation of the results is presented.</p>

<p>Traditionally stone inscriptions or drawings are documented through pictures or rubbings. The latter ones represent an analogue copy of the stone&rsquo;s surface and its features which are reproduced on paper. The disadvantage of this technique is the physical impact to the stone and the contained elements. Images reproduce the surface without contact. However, they might be affected by geometrical distortions and need appropriate lighting conditions to show the signs properly.</p><p>These problems will be avoided by means of non-contact 3D measuring techniques, like fringe projection. Such high resolution 3D techniques provide an exact geometrical copy of the original petroglyph, offering better results in legibility compared to traditional techniques. Moreover, it gives a more objective base for analysis and has less impact on the sometimes sensitive and eroded surfaces. Furthermore 3D data allows more extensive and further possibilities in processing and gives better preconditions for the interpretation.</p><p>However, depending on factors like resolution, scanned surface and degree of overlap between individual scans original 3D datasets may represent large up to really massive volumes of data. An effective use of such datasets can only be realised if they are condensed and prepared in a suitable way. This means reduction of the data volume, minimising any disturbing influence emerging from the spatial shape of the surface and emphasizing relevant information. The corresponding preparation of the data will then be a good base for a interpretation performed by the human science specialist through an adapted visualization. In addition the data should be prepared for high performance presentation to a wider community via the internet.</p><p>Processed digital copies of the Petroglyphs are visualised in order to enable the user to inspect the processed scans of the objects. By inspecting the scans the application provides a mass of functionality for achieving different views into the Petroglyphs and their appearance. This comprises on the one hand a simple 2D viewer for the processed data, and on the other hand a 3D viewer with interactive changeable light positions and water levels as well as a viewer for applying various lookup tables (colour), predefined image filters (convolution) and template matching (matching) regarding individual characters.</p><p>Provided functionality of the 3D viewer is based on features of 3D computer graphics. Surface normal vectors from the grey values of the processed scans and a light direction vector from an interactively changeable light source are computed. In addition shading is complemented by water filling, whereby the gray values are limited by the water level selected. Individual modifications are possible to improve the subjective impression by the user, trying to support him in his process of interpretation. Interactive changes of the light source directly affect the shading of the surface and provide a better idea of the 3D surface of the inscription board. Dynamic virtual water filling enables the user to obtain an even better impression of the depth of the individual characters and emphasise weathered characters.</p><p>The paper will explain the developed techniques and document its potential at selected data sets.</p>

Semantic based Structuring of 3D technologies for their optimized use in cultural heritage documentation.

43rd Conference of Computer Applications and Quantitative Methods in Archaeology, CAA 2015, Siena, Book of Abstracts.
<p>Constant technological progress results in new possibilities to produce reliable and rich spatial data of cultural heritage objects: for instance, museums have started to digitize their collections, more and more archaeological excavations or features and entire CH buildings have been documented in 3D. It is now necessary to establish connections among different CH disciplines and several technical disciplines, and to work on collaborative projects.</p><p>Technicians and CH experts together evaluate the best technique for specific CH object documentation, implementation and use. This discussion arises from the knowledge gaps of each counterpart in respect to the other discipline. Projects such as Agora 3D (see below) clearly demonstrate the need for an evaluation of the different available techniques.</p><p>In order to make optimal use of these technological capabilities, it is important to identify and name the information required to best serve the reasoning processes in these application fields. Correspondingly it is necessary to know about the characteristics of digitization techniques producing the content adapted to the needs of the applications. Due to the considerable complexity of instruments and processes producing the data, it is helpful to have a clear structure which relates the capabilities of the instruments to the requirements of the applications.</p><p>The COST Action TD1201 &ldquo;Colour and Space in Cultural Heritage (COSCH)&rdquo; takes this need into account, aiming to enhance the understanding among these disciplines. We will focus on the already listed, structured and evaluated available 3D technologies. At the same time, experts in spectral and CH research started to list, structure, and evaluate their knowledge. These evaluations yield a structure of technologies, and ultimately the techniques and instruments using their characteristics. The understanding of these characteristics provides insights for their potential applications. The ontology knowledge model accessible through so-called &ldquo;COSCH<sup>KR </sup>App&rdquo; provides a knowledge structure. It benefits from the development of semantic technologies from the Semantic Web framework. Semantics, which provide meanings, are captured through the conceptual structure and are defined through the ontology. The overall aim of this ontology is the development of a software tool to enable a better understanding of data acquisition techniques and their support to optimally realize cultural heritage applications.</p>

S Wefers, A Cramer

PDF

COSCH e-Bulletin
<p>The paper presents different forms of documentation of a Late Antique and Early Byzantine water-powered workshop and milling complex in what is commonly known as Terrace House 2 in Ephesos, Turkey. The entire complex was documented by means of 3D laser scanning in 2009 and 2010. Geometrical data were processed and used in the form of a point cloud in the archaeological analysis. Narrow parts, complex structures, and small rooms of the well-preserved feature were surveyed efficiently using a 3D laser scanner. Additionally, panoramic images were captured. They offered the possibility to colour the point cloud, thus helping to identify and understand the feature better in the model. The developed consistent 3D point cloud of the entire feature provided the spatial data for analyses, reconstructions and technical drawings, such as ground plots and sectional views for publications.<br />In order to address specific questions, e.g. to determine the course of the chute, or the size and position of the water-wheels, it was essential to be able to work with complete geometric data. For that purpose the data were exported from original files, using a free software plugin, and made usable in an internet browser. The interface is easy to operate and allows measurement and marking of 3D distances and coordinates of single points, within one scanner position. These can be saved and exchanged. In addition, using this technique a selection of the 3D data will be made available to the general user.</p><p><a href="http://www.cosch.info/publications/bulletin-1-2014">http://www.cosch.info/publications/bulletin-1-2014</a></p>

Millstones of Aswan red granite found on the island of Elephantine, Egypt.

2014

S Wefers, Mangartz, F.

AmS-Skrifter
<p>In 2011, the millstones of Elephantine Island were documented. Elephantine belongs to the area of red granite at Aswan (the old city of Syene), which is mainly famous for its monumental building stones &ndash; e.g. the unfinished obelisk &ndash; but also provided a hard rock that served for making millstones. Therefore, it is not surprising that all the Elephantine millstones are made from red granite. There are signs of quarrying on Elephantine, but no special millstone extraction sites could be identified. However, the presence of roughouts within the documented millstones proves their production on the site, maybe also from thereabouts. Seven Olynthiantype top stones, of which two are roughouts and two are stones left in an early stage of work, were recorded &ndash; Olynthian-type lower stones have not been found. Amongst the rotating millstones, there is a type not yet described for Egypt: we call them pseudo-Pompeian-type millstones. Their cylindrical top stones reach up to 60 cm in diameter, amongst the five bell-shaped lower stones, there is only one roughout. For the reconstruction, we suggest a design similar to the German &ldquo;Haltern-Rheingönheim&rdquo; millstones. The pseudo-Pompeian-type millstones seem to date from Late Antique to early medieval times but could have been in use for a much longer period. Only one rotary quern was found on Elephantine. Two top stones of edge-runners served as mills for crushing olives and three huge granite beams were used as foundations for oil presses.</p>

ISPRS Technical Commission V Symposium
<p>This paper documents the formulation of an international, interdisciplinary study, on a concerted European level, to prepare an innovative, reliable, independent and global knowledge base facilitating the use of today&rsquo;s and future optical measuring techniques for the documentation of&nbsp; cultural heritage. Cultural heritage professionals, color engineers and scientists share similar goals for the documentation, curation, long-term preservation and representation of cultural heritage artifacts. Their focus is on accuracy in the digital capture and remediation of artefacts through a range of temporal, spatial and technical constraints. A shared vocabulary to interrogate these shared concerns will transform mutual understanding and facilitate an agreed movement forward in cultural heritage documentation here proposed in the work of the COST Action Color and Space in Cultural Heritage (COSCH). The goal is a model that captures the shared concerns of professionals for a standards-based solution with an organic Linked Data model. The knowledge representation proposed here invokes a GUI interface for non-expert users of capture technologies, facilitates, and formulates their engagement with key questions for the field.</p>

The Labeling System: A New Approach to Overcome the Vocabulary Bottleneck

2014

Thiery, F., K -C Bruhn, Piotrowski, M., Colavizza, G.

DH-CASE '14
<p>Shared controlled vocabularies are a prerequisite for collaborative annotation and semantic interchange. The creation and maintenance of such vocabularies is, however, time-consuming and expensive. The diversity of research questions in the humanities makes it virtually impossible to create shared controlled vocabularies that cover a wide range of potential applications and satisfy the needs of diverse stakeholders. In this paper we present a novel conceptual approach for mitigating these problems. We propose that projects define their own vocabularies as needed and link the vocabulary terms to one or more concepts in a reference thesaurus, so that the project-specific term effectively serves as a &quot;label&quot; for a set of shared concepts. We also describe the implementation of this approach in the Labeling System. The Labeling System is a Web application that allows users to easily import concepts or create SKOS vocabularies and link the vocabulary terms to concepts from one or more reference thesauri.</p>

Lünen, Travis 2013].<br>Dem gegenüber stehen Disziplinen wie etwa die Kunstgeschichte und die Liturgiewissenschaft, deren Untersuchungsgegenstände sich in kleineren Räumen befinden oder selbst kleinere Räume sind, wie Kirchen, Paläste und Häuser, Plätze, Gärten und urbane Strukturen [Ananieva et al. 2013]. Hier ist es notwendig, den dreidimensionalen Raum zu betrachten. Die dritte Dimension spielt in solchen kleineren Räumen naturgemäß eine größere Rolle, die Projektion auf die Fläche führt dementsprechend zu einem größeren Informationsverlust. Allerdings gibt es in den Digital Humanities bisher nur wenige entsprechende Forschungsansätze [cf. Paliou, Knight 2010].<br>Das Mainzer Projekt “Inschriften im Bezugssystem des Raumes IBR” erarbeitet Wege, 3D-Informationen in den Mittelpunkt raumbezogener geisteswissenschaftlicher Forschung zu stellen. Eine im Projekt entwickelte Erfassungs- und Visualisierungssoftware bietet dabei die Möglichkeit, visuelle und textuelle Informationen zu dreidimensional vermessenen Objekten in ihrem historischen räumlichen Bezugssystem zu erfassen. Die Dichte dieser multimedialen Daten wird mit dem Werkzeug nach Kategorien und Zusammenhängen abfragbar und visuell erfahrbar. Forschungsaussagen gewinnen dadurch an empirischer Qualität.</p>

AGIT_25 - Symposium und Fachmesse Angewandte Geoinformatik
Bürgerbeteiligung ist jeher ein demokratisches Gut um Menschen mit den verschiedensten Interessen und Hintergründen an politischen Prozessen teilhaben zu lassen. Immer häufiger findet diese Beteiligung über digitale Medien und im Internet statt. Neben der Bereitstel-lung von Informationen werden Foren zum Austausch und der Organisation immer wichti-ger. Mit KuLIS, dem KUlturLandschaftsInformationsSystem des Landes Rheinland-Pfalz, wurde durch das Institut für Raumbezogene Informations- und Messtechnik der Fachhoch-schule Mainz (i3mainz) eine technisch innovative Internetplattform aufgebaut, die enga-gierten Bürgern die Möglichkeit bietet Informationen der Kulturgüter in Rheinland-Pfalz zu erfassen und langfristig zu dokumentieren. In dem Projekt angewandtes Crowdsourcing ermöglicht die Erzeugung einer Fülle an Daten, welche auf konventionellem Wege große Kosten verursachen würden. So können Bürger dazu beitragen Daten mit Relevanz für politische Entscheidungsprozesse zu gewinnen. Aber wer stellt die Korrektheit dieser In-formationen sicher? Wie wird diese bewertet und durch wen? Lässt sich dabei eine amtliche Qualität der gewonnen Daten gewährleisten? Die vorgestellten Ergebnisse der Herausforde-rung und Umsetzung einer Qualitätssicherung im KuLIS geben Antworten auf diese Fragen und sollen als Anregung Einzug in Projekte mit vergleichbarem Hintergrund finden.

XXIV International CIPA Symposium
<p><span class="pb_abstract">Since 2010, the state of Rhineland-Palatinate in Germany has developed a cultural landscape information system as a process to secure and further enrich aggregate data about its cultural assets. In an open dialogue between governing authorities and citizens, the intention of the project is an active cooperation of public and private actors. A cultural landscape information system called KuLIS was designed as a web platform, combining semantic wiki software with a geographic information system. Based on data sets from public administrations, the information about cultural assets can be extended and enhanced by interested participants. The developed infrastructure facilitates local information accumulation through a crowdsourcing approach. This capability offers new possibilities for e-governance and open data developments. The collaborative approach allows governing authorities to manage and supervise official data, while public participation enables affordable information acquisition. Gathered cultural heritage information can provide incentives for touristic valorisation of communities or concepts for strengthening regional identification. It can also influence political decisions in defining significant cultural regions worth of protecting from industrial influences. The presented cultural landscape information allows citizens to influence the statewide development of cultural landscapes in a democratic way.</span></p>

<p>The emergence of the Semantic Web and its underlying knowledge technologies has brought changes in data handling. Transferring expert knowledge to machines through knowledge formalization provides us the required support in managing huge datasets like the information in the World Wide Web. In the field of geospatial technology semantic technologies not only entail the capability to achieve higher degree of data integration but also infer semantics to discover new and hidden knowledge. This is of particular interest in the field of archaeology, where complex interrelations among heterogeneous datasets exist. Although researches on semantics are active areas in geospatial communities, their initial use is mainly for spatial data integration. This article tries to go one step further and imply semantics for spatial knowledge discovery through spatial built-ins within SWRL and SPARQL. The work resembles the approach of the Open Geospatial Consortium (OGC) to define standards for ­GeoSPARQL.<br></p>

Angewandte Geoinformatik 2012
<p>Im Jahre 2010 hat das Land Rheinland-Pfalz mit dem Aufbau eines Kulturlandschaftskatasters einen landesweiten Prozess zur Sicherung und Entwicklung seiner Kulturgüter angestoßen. In einem offenen Dialog zwischen öffentlicher Verwaltung und interessierter Öffentlichkeit setzt dieses Vorhaben gleichermaßen auf das aktive Zusammenwirken öffentlicher und privater Akteure. Das Kataster &ndash; als digitale Informationsplattform konzipiert &minus; baut auf einen Datenbestand im Lande existierender öffentlicher und privater Datenbanken auf und kann von jedem interessierten Nutzer beliebig erweitert werden. Das technische Grundgefüge dieser offenen Lösung setzt sich aus einem WebGIS zur digitalen Verortung kulturlandschaftlicher Elemente und einem Wiki zur Erfassung beschreibender Informationen zu den Elementen zusammen. Angereichert ist das Wiki mit Technologien des semantischen Webs, mit deren Hilfe Auswertungen der Inhalte vorgenommen werden können. Auf dieser Basis können kulturlandschaftlich bedeutsame Räume ausgewiesen werden, die auf kommunaler Ebene Anreize für eine touristische Inwertsetzung schaffen können oder Anstöße zur Ausbildung von Entwicklungskonzepten zur Stärkung der regionalen Identifikation geben können.</p>

Introduction to a spatial layer within the Semantic Web framework: A proposition through web application ArchaeoKM

<p>Spatial technology has gained momentum under database systems. More specifically, the spatial operations and spatial functions are used to carry out spatial analysis which can be executed through these database systems. In addition, there has been significant amount of research in the field of the geospatial ontology domain in order to achieve the semantic interoperability between different data sources. Although, data interoperability is one of the main objectives of the Semantic Web technologies, the potentiality of the underlying knowledge tools and techniques have not been completely identified. With the growing influence of the Semantic Web technologies towards the application based on knowledge management and intelligent systems, the geospatial application benefits from this influence. This thesis emphasizes on the use of knowledge to manage spatial data within spatial information systems through the Semantic Web framework.</p><p>This research activity is carried out with the backdrop of the case study of the industrial archaeology. It sets up an ideal environment for the application of knowledge to manage the huge and heterogeneous dataset. The use of knowledge to manage the diversity of information was well executed through the application prototype named ArchaeoKM which is based on the Semantic Web. The ArchaeoKM framework follows the 4Ks processing steps: Knowledge Acquisition, Knowledge Management, Knowledge Visualization and Knowledge Analysis. The same processing principle of 4Ks was implemented during the spatial knowledge processing. A top level ontology was developed in order to serve as the background representation of the case study in order to adjust the spatial components. Keeping the custom, the spatial knowledge processing begins with acquiring spatial signatures of the identified objects. The spatial signatures are stored within the spatial database system with proper mapping to the objects in the knowledge base. The spatial knowledge of these objects is managed through executing the spatial functions at the database level and enriching the knowledge base with the results. This spatially enriched knowledge base is used again to analyze the spatial knowledge. This research thesis benefits from Semantic Web Rule Language in order to infer knowledge. In addition, the spatial built-ins proposed during the course add up spatial dimension to the SWRL for spatial inferences. Similarly, a spatial extension of the query language SPARQL is proposed in order to query spatial knowledge from the knowledge base.</p><p>Actually, this research thesis provides the initial steps in integrating spatial components within the Semantic Web framework. This integration process is important for both technologies. Regarding the Semantic Web, the integration of non-typical semantic information within this framework opens up doors to other data pattern making the transformation of technologies easier. Likewise, geospatial technologies and GIS systems benefits through the inclusion of knowledge in the analysis process making the analysis much closer and efficient to human interpretation.</p>

<p>Die buddhistische Steinschriften (8. - 12. Jh. n. Chr.) der Provinz Sichuan im Südwesten Chinas repräsentieren eines der bedeutendsten Kulturgüter Chinas, welche archäologisch, kunsthistorisch und textwissenschaftlich dokumentiert, analysiert, interpretiert und visuali-siert werden müssen. Einerseits sollen diese buddhistischen Steinschriften für zukünftige Generationen konserviert werden. Andererseits sollen weitere Voraussetzungen zur Analy-se der Daten geschaffen werden, indem diese einer breiten Öffentlichkeit zugänglich ge-macht werden, um beispielsweise die geschichtliche Entwicklung des Buddhismus in China und seine Anpassung an die chinesische Kultur zu erforschen.</p>

<p>Das Herstellen von Kopien bedeutender archäologischer Fundstücke hat eine lange Tradition am Römisch-Germanischen Zentralmuseum (RGZM) in Mainz. Der Artikel beschreibt kurz einige Verfahren und Möglichkeiten zur berührungslosen Erstellung von virtuellen Modellen sowie Kopien als Ergänzung zu den etablierten Verfahren. Anhand mehrerer Beispiele aus dem RGZM werden verschiedene Vorgehensweisen gezeigt. Die beschriebenen Beispiele sind mit den klassischen Methoden der Kopienherstellung nicht möglich. Beschränkungen bestehen noch in der Oberflächenqualität der 3D-Drucke, teilweise in der geometrischen Auflösung feiner Strukturen sowie der Farbe der Drucke.</p>

Angewandte Geoinformatik 2010 - Beiträge zum 22. AGIT-Symposium
<p>Seit Ende 2006 wird das Umfeld des keltischen Oppidum &bdquo;Hunnenring&ldquo; im nördlichen Saarland untersucht. Reiche Grabfunde des 5./4. und 1. Jh. v. Chr. aus dem unmittelbaren Einzugsgebiet der treverischen Befestigung weisen auf die Ansiedlung einer keltischen Oberschicht in dieser heute peripher gelegenen Mittelgebirgsregion hin, aber auch für die anschließende römische Zeit bezeugt die Fundsituation des Raumes eine intensive Besiedlungstätigkeit.</p><p>Ziel dieses Artikels ist die Modellierung von Besiedlungsstrategien der eisenzeitlichen und römerzeitlichen Bevölkerung für ein Teilgebiet des Untersuchungsraumes rund um den Hunnenring von Otzenhausen. Zu diesem Zweck wird eine gemeinhin als Archäologische Prädiktionsmodellierung (engl. Predictive Modelling) bezeichnete Methodik angewendet, die auf einer Analyse des Naturraums und bestimmter Annahmen potentieller menschlicher Verhaltensweisen aufbaut. Mit Hilfe der Theorie von Dempster-Shafer, einer Methodik aus dem Bereich der Wahrscheinlichkeitstheorie, werden die zuvor definierten Einflussgrößen in einem Geographischen Informationssystem (GIS) modelliert und erlauben auf diese Weise Bereiche unterschiedlicher Siedlungspräferenzen herauszubilden. Zur Modellvalidierung wird das Ergebnis schlussendlich mit dem bekannten Fundkontext des Untersuchungsgebietes in Beziehung gesetzt und kritisch bewertet.</p>
