1. A computer system comprising:
- a processor;
a computer readable memory encoded with logic that when executed by the processor is operable to perform operations comprising;
deriving concept terms by extracting significant terms from search text and inferring relevant terms from the extracted significant terms using a concept matrix, the concept matrix derived from a plurality of sample documents using singular value decomposition of a term-document matrix, the concept matrix identifying a latent pattern of word usage in the plurality of sample documents around a concept, the concept matrix further providing a term-term similarity between the search text and terms in the plurality of sample documents; and
generating a query for a search engine, the query comprising a search expression having at least one of the derived concept terms.

Abstract
A concept bridge employable with a search engine, method of operating the same and computer information system employing the concept bridge and method. In one embodiment, the concept bridge includes an extractor configured to derive concept terms by extracting significant terms from search text and inferring relevant terms therefrom. The concept bridge also includes a query generator configured to generate a query consistent with an index of a search engine as a function of the concept terms.
