EXTENDING AN XML MEDIATOR WITH TEXT QUERY

Abstract

Supporting full-text query in an XML mediator is a difficult problem. This is because most data-sources do not provide keyword search and ranking. In this paper, we report on the integration of the main functionalities of the emerging XQuery Text standard in XLive, a full XML/XQuery mediator. Our approach is to index on keywords virtual documents in views. Selected virtual documents are on demand mapped to data source objects. Thus, the mediator selection operator is efficiently extended to support full-text search on views. Keyword search and result ranking are integrated. We rank results using a relevance formula adapted to XPath, based on number of keywords in elements and distance from the searched nodes.
