Content based user centric model of a network search system

by: Peter Vojtas

Abstract: Our goal is a progress in automated processing of web data and user preference search (of course Google does it with its indexes, keyword queries and (anthropological) user profile modeling). Our added value is an improvement of web information extraction (alas semantification) and methods for learning user objectives and utility for a multicriterial top-k user preferences querying.
We present models, methods and prototype experiments, mention connected problems of ontology engineering and uncertainty modeling. At the end I briefly present a profile of our Department of Software Engineering.

Bio: Peter Vojtas is a full professor of Computer Science at the Department of Sofware Engineering (School of Computer Science, Faculty of Mathematics and Physics), Charles University in Prague, Czech Republic.
He also keeps a part time position at the Institute of Computer Science, Czech Academy of Science, Prague. He has held the Alexander von Humboldt Foundation Research Fellow, Bonn, Germany in 90's. He has founded Institute of Computer Science at the P. J. Safarik University, Kosice, Slovak republic and acted as founding director several years. In 2004 he permanently moved to Praue. In spring 1994 he was visiting professor at Ohio University, Athens, Ohio, USA.
Peter Vojtas has MSc Suma Cum Laude in Theoretical Cybernetics and CSc(PhD) in Mathematical Logic from Charles University, Prague. He got Professor Titulaire in Mathematical Informatics from the President of Slovak Republic and DrSc.- Doctor of Science from Czech Academy of Science. His research interests include:

• computational intelligence, connecting web to the user, process of the Web semantization
• user preferences - modelling, learning, querying/searching with, user objectives and utility
• uncertainty and preferences in databases and indexes, web reasoning, information systems
• many valued/fuzzy logic programming/Datalog - deduction, induction, abduction
• formerly - set theoretic aspects of asymptotics and Galois-Tukey connections, etc.

He is a member of ACM, IEEE Computer Society and Computational Intelligence Society, Geselschaft fuer Informatik, Czech Society for Cybernetics and Informatics and DVMLG. He acts in editorial board of Computing and Informatics, Neural Network World, several organizing and program committees of conferences, several bodies of Czech Science Foundation and Ministry of Education.
