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 ‘Labeling Approach’. 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.


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

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 "label" 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.


Schneller und ausdauernder als das menschliche Auge: Modulare Okularkameras am Motortachymeter

Allgemeine Vermessungs-Nachrichten (avn)

Bis zu 62 500 Zielungen pro Sekunde werden derzeit mit einer USB 3.0 Industriekamera am geodätischen Tachymeter erreicht. Exemplarisch betrachten wir die Einsatzmöglichkeiten solcher Systeme für die Erfassung hochfrequenter Schwingungen, stellen aktuelle Grenzen dar und schlagen einen pragmatischen Weg für eine präzise zeitliche Zuordnung der Beobachtungen mithilfe eines GPS-Zeitempfängers vor.

Neben hochfrequenten Zielungen erlaubt das am Institut für raumbezogene Informations- und Messtechnik i3mainz entwickelte Konzept MoDiTa – Modulare DigitalkameraTachymeter – ein hochgenaues Monitoring über lange Zeiträume. Mithilfe der modularen Okularkameras und einem Kollimator als Ziel werden die bekannten Verfahren zur automatischen Zielerfassung und Zielverfolgung von Punkten im Raum (wie z.B. ATR) mit der hochgenauen Erfassung absoluter Ausrichtungen im Raum ergänzt.


Modular Imaging Total Stations - Sensor Fusion for high precision alignment

3rd International Conference on Machine Control & Guidance Proceedings

Initialized in 2009, the Institute for Spatial Information and Surveying Technology (i3mainz), Mainz University of Applied Sciences, forces research towards modular concepts for imaging total stations. On the one hand, this research is driven by the successful setup of high precision imaging motor theodolites in the near past, on the other hand it is pushed by the actual introduction of integrated imaging total stations to the positioning market by the manufacturers Leica Geosystems, Sokkia, Pentax, Topcon and Trimble.

Modular concepts for imaging total stations are manufacturer independent to a large extent and consist of a particular combination of accessory hardware, software and algorithmic procedures. The hardware part consists mainly of an interchangeable eyepiece adapter offering opportunities for digital imaging. An easy assembly and disassembly in the field is possible allowing the user to switch between the classical and the imaging use of a robotic total station. The software part primarily has to ensure hardware control, but several level of algorithmic support might be added and have to be distinguished. Algorithmic procedures allow reaching several levels of calibration concerning the geometry of the external digital camera and the total station. Here the resulting resolution capacity of our sensor fusion and also the accuracy of the system are presented based on examples. We deliver insight in our recent developments and quality characteristics.

The sensor fusion between camera and polar measuring system allows detecting and measuring different types of targets with high precision. MoDiTa is used to calibrate inclination sensors and to control the long-term stability of laser and tripods.
