Theoretical principles of use of ontologies for semantization of the Web resources

Yu.V. Rogushina

Abstract


In this paper we show the main directions of semantization of the Web information resources and their theoretical bases. We consider the semantization problems associated with the open environment information at the knowledge level. This analysis substantiates the need for the Web semantic search methods and means. Modern principle tendencies in the personified semantic deal with the ontology-based formalization of knowledge about the information needs of users and their current tasks. Our approach is based on use of the semantically marked Wiki-resources as a source of knowledge for constructing of ontologies of individual task. Each task ontology is considered as a small subset of domain ontology with large number of terms volume and high complexity. We develop the formal model of the task ontology as a special case of the formal model of domain ontology and propose methods for constructing of this task ontology on base of the set of semantically marked Wiki pages. The software implementation of the retrieval systems capable to process such task ontologies is analyzed on example of MAIPS – semantic retrieval system which provides personalized satisfaction of user information needs. Such personification is based on knowledge contained into the user task thesauri that are built on base of task ontologies.
