We analyze common errors and complications in company names committed by users that make the company name-matching problem difficult. Although the company name-matching problem is a type of name-matching problem, it has special features that make these common name-matching methods barely the best choice in the company name-matching problem. Therefore, according to the construction of the company name, we propose a novel idea of position weight to address company name-matching problem. Then, we compare our proposed position-weighted measure with the Monge-Elkan measure and the soft TF/IDF in the popular business data set and two data sets from a major semiconductors manufacturer. The result indicates that the position-weighted measure performs best overall based on maximum F1 and our proposed rating measure in the company name-matching problem. Besides the company name, the position weighted measure can also be used in some name-matching problems that have similar construction with the company name.3986497 bytesapplication/pdf論文公開時間: 2019/7/26論文使用權限: 同意有償授權(權利金給回饋學校)公司名字串比對位置權重名稱匹配資料整合Company nameName-matching problemString similarityPosition weightData integrationthesis10.6342/NTU201600955http://ntur.lib.ntu.edu.tw/bitstream/246246/275281/1/ntu-105-R03323037-1.pdf
