Semantic Web data integration using F-Logic

The paper addresses data integration for heterogeneous knowledge sources in the Semantic Web domain. The objective of the works is to show that logic programming languages with second order syntax and with object oriented approach (HiLog + F-logic) provide adequate support for a data interation sysem. In particular, object oriented approach supporting the F-logic language provides a natural translation and manipulation of Web data. The paper describes elements relevant for the development of Semantic Web applications. Activities of data integration process are explained through the example of an application developed for a specific domain, searching data about scientific conferences.
