This paper pro poses a structured query and search model for applying link-based hypertext composites that can be represented with new Web standards in Web searching and describes a primitive prototype system that implements the model. We argue that by enabling users to query different levels of the composite structures with same or different keywords and getting search hits that are not separate nodes but sets of inter-linked nodes, the precision of the search results can be improved. Meanwhile, users may get more contextual information about the search results.

Adaptive web meta-search enhanced by contraint-based query constructing and mapping

This paper introduces an adaptive method that can be used to construct the query user interfaces for the information integration systems (IIS) on the Web, and a constraint-based method for mapping queries from such IISs into the specific formats of heterogeneous Internet sources. The fuse of this research was ignited by witnessing that WWW information searching becomes harder and harder due to the tremendous development of the Internet and the explosive growth of digital information on the World Wide Web. Incorporating adaptive and constraints-coordinated mechanisms into an information integration system can overcome the diversity of heterogeneous sources and utilize the functionality of the individual sources to the fullest extent.
