Opis:: In the paper an algorithm for automatic knowledge acquisition is proposed. The knowledge is acquired from aggregate data stored in different repositories. The algorithm operates by means of semantic data integration, allowing both syntax and semantic differences between data coming from different sources. If only we know data taxonomies, can interpret data schemas and design schema mappings, then the differences are not an obstacle to integration. The acquired knowledge is being defined in a form of production rules with uncertainty. The considerations are illustrated with medical examples.

Tytuł:: Schema mapping and query reformulation in peer-to-peer XML data integration system
Autorzy:: Pankowski, T.

query answering in peer-to-peer systems
Opis:: In the paper we discuss the problem of XML data integration in a P2P environment. In this setting each peer stores schema of its local data, mappings between the schema and schemas of some other peers (peer's partners), and schema constraints. The goal of the integration is to answer the queries formulated against arbitrarily chosen peers. The answer consists of data stored in the queried peer as well as data of its direct and indirect partners. We focus on denning and using mappings, schema constraints, and query reformulation in such scenario. We discuss a strategy that allows us to obtain a complete answer with the possibility of discovering missing values. The method is the theoretical foundation of the implementation of SixP2P system (Semantic Integration of XML data in P2P environment).
