Graduated as mathematical engineer in 1982, and as a sociologist in 1985. He got his PhD in Sociology in 1999. From 1987 he is working for the Technical University of Budapest as a teacher at the Department of Sociology. During his academic career he was CD-ROM editor and developer for IDG Hungary between 1994 and 1997, and adviser, finally chief scientist for Hungarian Telekom between 1997 and 2004. From 2002 he participated in a lot of R&D-projects like Web of Words (developing deep web search engine based on semantic-like standards) and Data Riddle (building a web traffic analyzer for the largest Hungarian portal). He designed the metadata model of National Audiovisual Archive (2005) and the open archive based architecture for the Hungarian National Digital Archive (2003-2004). In 2005-2006 he was the leader of a big national R&D Consortium called MEO. The most important objective of the MEO project was to build a top ontology and to form an ontology infrastructure. In 2009 he joined the ENCOMPASS 2.0 team, and he is responsible for the portal development. In 2007 he published a book about the new media (‘All in One‘), and in 2008 another one about the theory of action. Recently, he is trying to develop a formal approach of the theory of action. >>download_CV logo
