摘要: An information retrieval system that deals with the problems of synonymy, polysemy, and by concept allowing for a wide margin uncertainty in initial choice keywords query. For each input query vector an matrix, disclosed solves optimization problem which maximizes stability solution at given level misfit. The may include decomposition matrix terms orthogonal basis functions. Each encodes groups conceptually related keywords. bases are arranged order decreasing statistical relevance to search engine approximates weighted sum first few bases. Other commercial applications than can also be built on techniques.
