Research on Harmful Information Crawler System Based on Keywords Correlation
摘要
Abstract
Traditional approaches to harmful information detection on the Internet are based on Google,Baidu etc. ,users enter keywords for search,and then need to study the results obtained,however users often do not accurately describe the information they want,the key-words given by users are inaccurate,the search results often include what users don't want,some data which users care cannot be listed. It explores a crawler method based on meta-search,which introduces technology of keyword expansion. The method expands keywords in the Web capture and user query to improve information coverage and accuracy,with low cost and good effect,which can be applied to other domain with some extension.关键词
