A method for controlling the retrieval of information with a from the data type, the response time dependent strategy in order to reduce for the consumers.

摘要

An information fetching control scheme capable of reducing the response time for the user until the requested information is presented to the user in the WWW system is disclosed. A structured document is fetched by transmitting a fetching request to a server device, and a data structure of the fetched structured document is analyzed. Then, a data type indicating an information content of a candidate data for a next data fetching originating from the structured document is guessed according to an analysis result, and a data fetching strategy indicating whether a fetching of the candidate data should be carried out or not is determined according to the data type of the candidate data. The data fetching strategy indicating that the fetching of the candidate data should not be carried out or a partial fetching of the candidate data should be carried out is determined for prescribed types of data such that the response time for the user will be reduced.
