From Revisiting the LCA-based Approach to a New Semantics-based Approach for XML Keyword Search
Most keyword search approaches for data-centric XML documents are based on the computation of Lowest Common Ancestors (LCA), such as SLCA and MLCA. In this paper, we show that the LCA is not always a correct search model for processing keyword queries over general XML data. In particular, when an XML database contains relationships among objects, which is quite common in practical data, LCA-bas...
متن کاملProcessing XML Keyword Search by Constructing Effective Structured Queries
Recently, keyword search has attracted a great deal of attention in XML database. It is hard to directly improve the relevancy of XML keyword search because lots of keyword-matched nodes may not contribute to the results. To address this challenge, in this paper we design an adaptive XML keyword search approach, called XBridge, that can derive the semantics of a keyword query and generate a set...
متن کاملKeyword Search in XML Database with Relevance Ranking and Maintaining Stored Websites
Keyword search in XML Database is to provide access on XML database by overcoming keyword ambiguity. Here users are allowed to search on XML database using keyword search like Text Databases. A novel IR style approach which well captures XML’s hierarchical structure, and works well on pure keyword query independent of any schema information of XML data. A search engine prototype called XReal is...
متن کاملA System for Keyword Proximity Search on XML Databases
Keyword proximity search is a user-friendly information discovery technique that has been extensively studied for text documents. In extending this technique to structured databases, recent works [6, 7, 4, 2] provide keyword proximity search on labeled graphs. A keyword proximity search does not require the user to know the structure of the graph, the role of the objects containing the keywords...
متن کاملKeyword Search on Both XML and Relational Data
Keyword search is a familiar and effective method to retrieve information under databases for any user. Keyword search on structured/semi-structured databases has received significant attention in recent years. A number of solutions have been proposed and many prototypes have been developed. Building on growing user needs, recently several RDBMS (IBM DB2, etc.) have made themselves be compatibl...
متن کاملICRA: Effective Semantics for Ranked XML Keyword Search
Keyword search is a user-friendly way to query XML databases. Most previous efforts in this area focus on keyword proximity search in XML based on either tree data model or graph (or digraph) data model. Tree data model for XML is generally simple and efficient for keyword proximity search. However, it cannot capture connections such as ID references in XML databases. In the contrast, technique...
