Study on Web Information Search Model

From informatics we found that the basic reason of searching Internet information difficultly is the long distance of information arisen by the huge whole net information structure state.With the continuously enlarging of the net scale,the solution is to look for a valid method of how to shorten the information distance.We can optimize the whole net structure in logic function and construct the net structure with the shortest information distance. The solution that the author puts forward includes:the Web information search agency model,the Web information search agency model based on the customer's demand,and the Web information search agency model with whole information based on the domain ontology.
