Class Tag Clustering Algorithm of Clustering Search Engine

In order to solve the problems including semantic search, label cluster, theme-related difference of search engines especially under the Chinese environment, this paper aimed to construct a cluster search engine retrieval model suitable for semantic search environment for Chinese through introducing ontology and class label mechanism. Based on the improvement of traditional STC algorithm as well as ontology library and suffix array, this paper studied the class label extraction method of cluster research engine, and put forward related arithmetic of label cluster. The study of cluster research engine label cluster broke through the bottleneck of the semantic research of research engine and information resource management, and solved the single on-line research problem of metasearch and robot engine.
