Full Text Search in XML Documents
The goal of this paper is to show how XML structure information can be used for full text search in XML documents. Existing products for full text search are investigated regarding their support of XML. The main aspect of this investigation is how the search scope of queries is specified and narrowed by taking advantage of the XML format. Considering the results of this investigation, a suggest...
متن کاملPersonalizing XML Full Text Search in PIMENTO
XML search is increasing in popularity as more and larger XML repositories are becoming available. The accuracy of XML search varies across different systems and a lot of effort is put into designing scoring functions tailored to specific datasets. For example, the INEX effort [8] aims at improving the search relevance of IEEE XML data collections. To the best of our knowledge none of the exist...
متن کاملOn Wrapping Query Languages and Eecient Xml Integration (full Version)
Modern applications (portals, e-commerce, digital libraries, etc.) require integrated access to various information sources (from traditional RDBMS to semistructured Web repositories), fast deployment and low maintenance cost in a rapidly evolving environment. Because of its exibility, there is an increasing interest in using XML as a middleware model for such applications. XML enables fast wra...
متن کاملXML Full-Text Search: Challenges and Opportunities
An ever growing number of XML repositories are being made available for search. A lot of activity has been deployed in the past few years to query such repositories. In particular, full-text querying of text-rich XML documents has generated a wealth of issues that are being addressed by both the database (DB) and information retrieval (IR) communities. The DB community has traditionally focused...
متن کاملFull-Text and Structural XML Indexing on B+-Tree
XML query processing is one of the most active areas of database research. Although the main focus of past research has been the processing of structural XML queries, there are growing demands for a full-text search for XML documents. In this paper, we propose XICS (XML Indices for Content and Structural search), novel indices built on a B-tree, for the fast processing of queries that involve s...
