| Abstract: | By using vertical search engine technology,you can quickly and accurately check the information in the vast amount of agricultural knowledge resources that meets user needs. There are some defects in the current agricultural subject vertical search engine filtering technology,such as ignoring WEB content,easily occurring topic drift and so on. Based on detailed analysis of the current algorithm and combining PageRank algorithm,the vertical search engine filtering algorithm aiming at agriculture information ... |
