  • Patent number: 7809717
    Abstract: A method and apparatus is provided for visually coding or sorting search results based on the similarity of the search results to one or more concepts. A search query containing search terms is used to conduct a web search and obtain search results comprising a number of document surrogates describing the located web pages. Concepts are obtained using the search terms and the similarities between the obtained concepts and the search results are evaluated. The search results are then displayed in a manner that indicates the relative similarity of search results to one or more of the determined concepts, such as by sorting the search results based on the level of similarity of the search results to one or more concepts or by providing an accordance indicator with each displayed search result, the accordance indicators indicating the similarity of the corresponding search result with one or more of the concepts.

  • Patent number: 7752243
    Abstract: A data structure, apparatuses and methods for expanding a search query to be used by a web search engine is provided. The search query is expanded by accessing a concept knowledge base data structure having concept data objects and term data objects with each term data object defining a term and associated with at least one of the concept data objects. Search terms making up the search query are matched to term data objects and a concept set is generated containing concept data objects associated with the term data objects. A second set of term data objects are generated by using the concept data objects to locate term data objects associated with the concept data objects. A user can then select one of the term data objects in the second set to expand the user's search query.
