example 1

[0072] Through the data processing method provided by the present invention, such as Figure 2-3 As shown, from Henan Bidding Network (http: / / www.hnzbw.cn / newshow1.asp?id=1920507&l=1) and Xuchang Municipal Government Procurement Network (http: / / www.hngp.gov.cn / henan / content?infoId=1540448944097797&channelCod e=H710202&bz=0) respectively extracted two titles related to "Xuchang Caowei Ancient City Development and Construction Co., Ltd. "Xuchang Caowei Ancient City South Gate, South Street Central Axis Wireless Wi-Fi and Block Security" project transaction result announcement" The contents of the bidding announcements are recorded as text data.

[0073] Using the above two text data records (bidding announcement content) as the input of the above steps S120-S130, the similarity value of the text data records obtained is 0.81, which is greater than the preset threshold value of 0.6, and is respectively output after the NER processing in the step S140 "Person name: Wang Qiang, Q...

[0075]By the data processing method provided by the present invention, from Beijing Construction Engineering Information Network (http: / / www.bcactc.com / home / gcxx / zbjggs_show.aspx?gcbh=230F0SG201800046) and Beijing Construction Engineering Information Network (http: / / www.bcactc.com / home / gcxx / zbjggs_show.aspx?gcbh=230F0JL201800020) extracted two data records as text data records whose title involves the project of "Special Service Fire Station Project in the Southern New District of Beijing Economic-Technological Development Zone".

[0076] The above-mentioned two text data records (the content of the winning bid publicity) are used as the input of the above-mentioned steps S120-S130, and its similarity value is 0.875, which is greater than the preset threshold value of 0.6. After the NER processing in the step S140, the output "personal name:; organization Name: Beijing Economic-Technological Development Zone Infrastructure Office Beijing Economic-Technological Development Zone...

Abstract

The invention relates to a public resource transaction data-oriented cleaning and duplicate removal method and system. The texts corresponding to public resource transaction data are stored in a dataset in a text data record form, wherein the data sets are grouped according to a preset rule, the number of the text data records in each group is controlled, and the data similarity among the text data records in each group is calculated based on the longest common subsequence. When the data similarity between the two text data records is larger than a preset threshold value, the named entity information of the two text data records is further compared, and when the named entity information of the two text data records is the same, it is judged that the two text data records belong to the repeated data, and otherwise it is judged that the two text data records belong to the non-repeated data. The repeated information in the public resource transaction data is determined in a multi-dimensional cross validation mode, so that the misjudgment of the repeated data can be further prevented on the basis of improving the text processing performance.
