Ontology-centric Source Selection for Meta-querier Customization
With an increasing number of semi-structured data sources, meta-queriers are introduced to facilitate effective information retrieval from multiple data sources that are accessible through query forms. However, a one-size-fitsall meta-querier cannot cater for various individual needs. In meta-querier customization, source selection is arguably one of the most critical problems. This paper proposes a capability-based source selection to meet user needs in terms of query capabilities. The major challenges include modeling, understanding and matching of the user needs and source capabilities.
