Terms are extracted from service description documents describing desired services, and the terms are used to search for candidate service providers operable to provide the desired services. A matrix of terms and documents are determined from the service description documents. Singular value decomposition (SVD) is used to decompose the matrix. Eigen vectors from the SVD decomposition are weighted by top k singular values in a diagonal matrix S of singular values also generated from the decomposition. The weighted eigen vectors are used to rank terms from the matrix X based on relevance of the terms to the requirements for desired services described in the service description documents.
