摘要
从信息学角度发现互连网信息搜索困难的根源是全网信息结构状态数量巨大所导致的信息距离遥远。解决的手段是在互连网规模不断增大的客观条件下,寻找如何缩短信息距离的有效方法。可以在逻辑功能层面优化互连网全网信息结构,构建具有最短信息距离的互连网全网信息结构。作者提出的全网信息结构模型有:中介的Web信息搜索模型、基于用户需求的Web信息搜索中介模型、基于领域本体全信息的Web信息搜索中介模型。
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.
