Toward automatic information search and convergence: A method on dynamic information requirement expression generation

As available information on networked environment becomes more abundant, diversified, and dispersed, traditional fixed information service mode will be substituted by on-demand information search and convergence. Therefore, dynamic and precise express of user information requirement becomes an important impact factor of information service quality. Based on TIREM (task information requirement express model), a method is proposed on dynamic information requirement expression generation, along with a demo software developed to verify the feasibility of TIREM and the proposed method.
