| Abstract: | In order to improve the precision of meta search engine,an improved results merging algorithm based on PageRank is proposed.With meta search engine technology analyzed and the disadvantages of PageRank algorithm considered,rtf algorithm is proposed.The improved merging algorithm could realize query based on synonym or near-synonym.It use in the professional search engine of coal geology,proves to be effective. |
| Keywords: | meta search professional search search-result merging PageRank algorithm coal geology |
