Structured Web pages management for efficient data retrieval

The widespread use of the World Wide Web in recent years has opened up universal access to a vast number of information sources. An obstacle that affects the access to Web data is the lack of an information structure among and within Web pages. This raises a need for structured Web page management for efficient Web information searching. Our proposed structured Web page management is built in two stages: (i) HTML transformation to XML, and (ii) a navigation hierarchy. Also, we study how querying Web data can be accomplished in our structured Web page management, by which users may follow a navigation hierarchy to browse both inter-page and intra-page structures of the Web database and can specify queries for desired information.
