摘　　要：文本作为一种占比80%的信息存储形式,对文本信息中重复数据的识别尤为关键,如何进行文本重复记录检测,检测文本之间是否存在抄袭现象,成为自然语言处理领域研究热点。以国家开放大学Moodle学习平台发帖重复记录检测的数据为依据,研究了文本类重复记录检测方法,通过以今日头条新闻为样本进行重复记录检测,算法准确率为93.1%,召回率为95.9%,验证了该方法的可行性。然后应用于Moodle学习平台发帖数据的平台内部、平台与外部数据重复记录检测,可有效发现重复发帖,为管理者和教师提供了有价值的反馈。As an information storage form, a text accounts for 80% of the total information. It is particularly important to recognize duplicate data in text information. How to detect duplicate records and detect whether there is plagiarism between texts has become a hot research topic in the field of natural language processing. Starting from duplicate record data of Moodle platform deployed by the Open University of China, this paper studies the detection method of duplicate records of text information. Through the detection of duplicate records of news source from Headlines as sample, the accuracy rate of the algorithm is 93.1% and the recall rate is 95.9%. The experiment verifies the feasibility of this method, and then applies it to the detection of duplicate records of internal, systematic and external data of Moodle platform. This method provides valuable feedback for managers and teachers.
