Patent ID: 7792786

Claim:
A method for use with a set of seed documents P 0 extracted from a data warehouse, the method comprising: searching the data warehouse to provide a set of additional documents P 1 similar to documents of P 0 , wherein said similarity is determined using a query search; generating an initial taxonomy for a combined document set P 0 +P 1 that includes all documents from both the set of seed documents P 0 and the set of additional documents P 1 , wherein said generating of the initial taxonomy includes an analysis using words, bags of words, phrases, structured and unstructured features; classifying the combined document set P 0 +P 1 using terms obtained from structured fields, wherein the structured fields are extracted from the combined document set P 0 +P 1 wherein at least one of the structured fields includes names of people and is formed using a name annotator to extract names from documents of the combined document set P 0 +P 1 ; generating a contingency table that compares categories of a refined taxonomy to the structured fields in cells and assigns a degree of significance to the comparisons in each cell; examining the contingency table to find a relationship between the categories of the refined taxonomy and the names of people wherein said relationship is plotted according to the degree of significance of respective cells to determine who is related to which document categories, hence who has what expertise; overlaying trending information on top of a document taxonomy and contingency table; using the contingency table to identify recent and most related expertise taxonomies and people; iterating the processes of extracting, searching, and generating using domain knowledge to produce the refined taxonomy from the initial taxonomy; comparing one name classification against another name classification in the refined taxonomy; and identifying people with similar expertise by examining highly related people names using network graph analysis or other relationships in the structured and unstructured fields.
