    Towards supporting annotation for existing web pages enabling hyperstructure-based searching
    ( 2005)
    Qiu, Z.
    ;

    This paper discusses the requirements and tasks in annotating existing Web pages with additional structural and semantic information. It suggests annotating existing Web pages with the concepts of a domain model, and annotating the links between the Web pages with the relations between these concepts. It also suggests explicitly representing high-level hypermedia structures, so-called hypertext composites and contexts, and annotating the corresponding composite and context pages with such structures. RDF and RDF Schema are adopted to represent the domain models and the resulting annotations. The architecture of a prototype annotation tool is outlined and corresponding requirements for automatic annotation support are discussed.

    Using Hypertext Composites in Structured Query and Search

    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.
