Social network not only plays an important role in People's Daily life,but also has enormous commercial potential.There is an importa nt purpose of User Identity Linkage,which connects the user identities that belong to the same person in real worl d and mining the commercial potential in social network to provide support for business decisions.As one of the main research fields of User Identity Linkage,connecting the user identities by matching the usernames,which is called connecting username in this paper,has regarded in domestic and international scholar.And it is mainly to English users,however,the connecti ng username to Chinese users has not got a systematic research.This paper has made careful research and analysis to properly connect Chinese user identities by matching the usernames.And the work of this thesis are:1,Based on the features of Chinese usernames,this paper has drawn out the problems that should be solved in connecting Chinese username.2,This paper proposes a kind of language mapping method,which can translate Chinese words into their corresponding Pinyin words to solve these problems: there are simplified or traditional Chinese characters,English characters and homophonic words in a given username.3,This paper has designed various matching modes of string for the difference of naming habits between English and Chinese.And combined with the similarity matching algorithms,we made a n experi ment on Spa rk to evaluate the effectiveness of each matching mode.At last,according to the precision,recall and F-Measure,we analyzed the effectiveness of each matching algorithm on dif ferent matching modes.4,In chapter 4,this paper introduced the UISL M and the application of research results in this paper in UISLM.
