Improved algorithm of Context Graph based on feature selection
Wei Liu, Jian Ming Zhao, Yongji Yang · Journal of Computational Methods in Sciences and Engineering · 2020
In order to solve the problem of low efficiency of traditional theme crawlers in searching theme pages, the crawling algorithm based on Context Graph was discussed. After analyzing the working principle and process of the algorithm, we introduced a new algorithm idea named feature selection algorithm. This new algorithm improved the original TF-IDF formula accordingly and solved the algorithm problems.
