Knowledge Based Search Engine: Granular Computing on the Web

Granular computing is an emerging technology. This paper summarizes its applications to the Web. A high frequent co-occurring ordered set of keywords is called a keyword set;it represents some concept in the given document set. These concepts forms a simplicial complex of concepts,which is regarded as a knowledge base for a new search engine.The return of a query will be organized ino meaningful clusters. A fundamental difference of this approach from semantic web is that the search engine carries the semantic of a Website, instead of the website has to be organized in the sense of semantic Web, namely, the semantics is machine readable.
