IS_A: Integrated Semantic Access in Situated Operations
Prof. Dr. Jon Atle Gulla - IS_A project manager
Jon Atle Gulla is professor of Information Systems at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway since 2002. He received his MSc in 1988 and his PhD in 1993, both in Information Systems at the Norwegian Institute of Technology. In his PhD thesis he used linguistic theories to generate user-tailored explanations of conceptual models and their executions. Gulla also has a MSc in Linguistics from the University of Trondheim from 1995. In 2003 he completed a MSc of Management (Sloan fellow) at London Business School with a thesis on strategic modeling and simulation of fast growing software companies. Before accepting the professorship at NTNU he was the general manager of Elexir Sprachtechnologie, a Munich software company developing computational linguistics software for the search engine of Fast Search & Transfer. He was a senior consultant and project manager in Norsk Hydro in Brussels from 1997 to 2000, focusing on large-scale SAP projects. As a research scientist with GMD (later Fraunhofer) in Darmstadt from 1996 to 1997, he worked on dialog models for information retrieval.
Gulla's research focus is on semantic enterprise technologies and enterprise engineering. He has a multi-disciplinary approach and works in close collaboration with industry. His research includes intelligent text mining and information retrieval, ontologies and enterprise models, enterprise architectures and systems, and the Semantic Web. His group develops innovative methods and tools for ontology engineering and ontology-driven semantic applications. An important part of his research is the evaluation of ontologies and their applications, as well as of business processes supported by enterprise business applications.

We are currently working on tagging and finding strategies to expand the semantics of tags and use the expanded semantics to build a structure over the tags. We are currently looking into tags from social bookmarking services (mainly delicious.com). The tags and their structure will in the next step be used for information access
