The proposed research investigates two topics of importance to distributed information management: easing the integration of sources into distributed systems, and providing appropriate levels of source transparency for different users and tasks. The context for the research is the TAMBIS (Transparent Access to Multiple Biological Information Sources) project, which has developed an ontology centred query processing system over a collection of highly heterogeneous sources.The proposed research will develop two extensions to the TAMBIS approach to source querying. The first involves techniques that support source integrators in adding new sources. At present, the addition of new sources, and responses to changes in the functionality of existing sources, is an ad-hoc, manual process. The project will investigate the generic techniques for assisting the source integrator in linking sources with concepts in the ontology, and for relating sources to each other. The second involves the development of mechanisms that allow users who are querying sources selectively to view or to influence the sources that are to be used in addressing a query. The intention is to investigate circumstances in which complete source transparency may not be appropriate, and to explore how best users may be more fully involved in the query planning process.
