  • Business object search using multi-join indexes and extended join indexes
    Patent number: 7562073
    Abstract: A method and search system for implementing fast access to business objects in a Service Oriented Architecture. The method and search system enables near real-time update of the data used for the results. The method is based on multi-join indexes with anchor surrogate identifiers combined with extended join indexes. The method executes much faster than previous approaches and also reduces response times for complex queries.

  • Taxonomy generation for electronic documents
    Patent number: 7243092
    Abstract: Systems and techniques to generate a term taxonomy for a collection of documents and filling the taxonomy with documents from the collection. In general, in one implementation, the technique includes: extracting terms from a plurality of documents; generating term pairs from the terms; ranking terms in each term pair based on a relative specificity of the terms; aggregating the ranks of the terms in each term pair; selecting term pairs based on the aggregate rankings; and generating a term hierarchy from the selected term pairs.
