Research Of Web Structure Mining

With Internet rapid expanding some new concepts such as network economy and attention economy have been found.Web mining is becoming knockout research problems by huge society benefit and weathy challenge chance. A lot of datas of web have been stroed abundance information. It is very useful for improving commerce net competition power to find rules and afford individuation service by using technology of data mining. Most abundant and latency information has been provided for web mining in the relation of page links. Web structure dining is based on hyperlink analysis.It has been gained useful information from man-made links structure .Pages can be sorted making use of it. And important content pages can also be found.so that we can reform web structure to gain better content structure.at that time we can also find better way to improve Network design by it.This desseration goes on research to web structure mining,the work as follows has been done.Firstly It summarizes relevant fields development and tecnology of web mining and web structures.Secondly two important algorithm of PageRank and Hits have been analyzed and compared.Thirdly go deep into researching algorithm used in existing web structure system.And improves its core algorithm .we mainly analyze three datas of page . PageRank and Authority and Hub.so that we can gain the best query result.At last we also design an improvement web structure system prototype with experimental result and data analysis .
