Abstract:
OntoGRator is a system for integration and organization of access to various information and knowledge stored in independent computerized sources that stay external to it. The sources can be of various structuralization: data in relational data bases, documents, XML files, web pages etc. It is assumed that the sources gathered knowledge of some domain like casting technology or metallurgy. Integration of such sources is realized by defining two kinds of ontologies: “domain otologies” representing concepts of the domain together with dependences between these concepts, and “data source ontologies” describing each data source. Use of the knowledge gathered in the system consists in navigating through notions of the domain ontology and – after identifying the interesting concept – in retrieval of the information about chosen this way topic (coming from different data sources). The paper discusses some architectural and implementation issues of OntoGrator as well as its distinctive application in the field of casting technology.
