Abstract
The techniques presented herein are directed towards providing a user-directed keyword-based search on a large collection of XML documents, and displaying a summary of results to the user. Prior to receiving search requests from a user, an offline analysis of a large collection of XML documents is performed to construct an inverted index of keywords. For each keyword, the index stores a set of location indicators that identify all the instances of the keyword found in the collection of documents. Once the index is constructed, keyword searching can be done efficiently by a keyword lookup in the index. Various display strategies enable the user to see the specific portion of a large XML document containing the keyword and/or path frequency information allowing the user to easily refine the search to specific paths within the collection of documents.
