Linking and Populating the Digital Humanities (DFG/NEH)
Together with the Indiana University, Bloomington we will develop tools that allow scholars to link data (using Linked Open Data) between digital humanities collections, using the Stanford Encyclopedia of Philosophy as a test case.
InFoLiS: Integrating Research Data and Literature in Social Science (DFG)
Scientific literature has always been the main source of inspiration for other researchers. Therefore, a lot of effort has been invested in the development of methods for searching relevant literature. With the incerasing use of computers in almost all areas of science, the importance of scientific data (results of surveys etc.) is constantly increasing. The InFoLiS project aims at providing integrated search mechanisms for literature and relevant datasets in the area of social science. The project is carried out in cooperation with the University Library and the Leibniz Institute for Social Science (GESIS).
A central problem which occurs when applying semantic technologies for data integration is the creation of correct mapping rules. Existing methods for the automatic induction of mapping rules must be corrected manually. This manual editing and adaption of the mapping rules requires a high amount of expert knowledge over the behavior of the rule system and the underlying infrastructure. Despite of this, the procedure is very error-prone.
Within the scope of the project MappingAssistant a tool will be developed, which will solve these problems with a new half automatic approach. This half automatic approach replaces the automatic induction of mapping rules with an interactive process in which the user controls the single induction steps. The resulting tool will also allow non technical people to perform the data integration of heterogeneous data sources by themselves.
The induction rules will be derived semi-automatically with new methods of artificial intelligence.
Linguistic aspects of sympolic knowledge representation (MWK)
This project, which is funded by a Margarete von Wrangell scholarschip, is concerned with combinations of logical and linguistic methods for web-based knowledge access. This issue is investigated from a mathematical as well as from a cognitive point of view.
Research Seed Capital (MWK)
The goal of this project is to design, implement and test robust and scalable reasoning services for supporting the semantic analysis of textual resources from the web. The design of these methods will be guided by the requirements of particular use cases from the area of computational linguistics; in particular information extraction and ontology-based querying of textual web contents.
ProMap - Probabilistic Mappings for the Semantic Web (DFG)
The project is concerned with the probelm of answering queries across heterogeneous information sources on the semantic web. It is assumed that these information sources are described using different ontologies that first need to be integrated via semantic mappings. A number of systems for generating such mappings have been developed in the past years, however, all of them suffer from inherent uncertainty in the mappings. In this project, we will developed methods and tools for quantifying this uncertainty in terms of probabilities and for answering probabilitic queries based on the evaluation of the uncertainty.
Forum Organic Electronics (BMBF)
The Forum organic electronics is one of the five 'Spitzencluster' funded by the ministry of science and education. The Cluster is concerned with matierials, devices, production processes and applications of organic electronics. We are involved in the subproject Polytos which is focussing on printed electronics as an alternative to silicon-based smart tags. In the context of this project we will build a scalable software infrastructure for managing data originating from smart labels in close cooperation with SAP and the university of Karlsruhe.
The project aims at developing a European platform for the evaluation of semantic web technologies. For this purpose, the project will design and and implement evaluation campaingns in terms of services that can be executed on the SEALS platform on demand. In the course of the project a European community concerned with the evaluation of semantic technologies will be built and two official evaluation campaings will be carried out covering technologies for supporting ontology engineering, logical reasoning and querying, ontology matching, web service discovery and composition as well as semantic search. The consortium consists of 10 partners from 6 European countries. Our main contribution to the project in in the area of evaluating ontology matching. This work is carried out in close collaboration with INRIA Rhones-Alpes in Grenoble.
Knowledge based information processing in complex, distributed areas of application by the means of local system architectures and distributed knowledge models is the topic of this project.
