  • Patent number: 6490579
    Abstract: A system and method for facilitating the retrieval of information from a system of distributed computers or information resources is disclosed. In particular, the system and method of the present invention improves upon metasearch techniques by including information resource profiles that provide directives to the metasearch engine for facilitating information recovery. These information resource profiles additionally allow for metasearches to recover information from non-indexed information resources such as when browsing the web. Contextual searching is further provided via a grouping of the information resource profiles. The present invention is further directed to tools for the creation and management of the information resource profiles.

  • Patent number: 6275820
    Abstract: A system and method for relative ranking and contextual summarization of search hits from multiple distributed, heterogeneous information resources based upon the original content of each hit is disclosed. In particular, the system and method of the present invention improve upon metasearch engine techniques by downloading the original documents (text or multimedia) identified by standard search engines as relevant and using the original content of each “hit” to re-rank them relative to each other according to the original query pattern for the search, providing a uniform ranking methodology for the user. The present invention is also directed to an improved summarization process where the downloaded documents are re-summarized relative to each other according to the original query pattern for the search, providing a uniform summarization methodology for the user.
