Problems solved by technology

[0004] In fact, due to the diversity and concealment of plagiarism forms, the complexity of grammar and syntax, etc., the two main types of plagiarism recognition technologies currently used, "digital fingerprint" and "word frequency statistics", can no longer meet the actual needs of plagiarism detection. Caused many missed and false detections, its "recall rate" and "precision rate" need to be improved

Embodiment Construction

[0028] Further description will be made below in conjunction with the accompanying drawings.

[0029] like figure 1 As shown, the present invention is based on the embodiment of the method for duplicating academic papers of a computer retrieval system, and its method steps include:

[0030] (1) Steps of establishing an academic paper source database (a corpus of academic papers in a certain professional field) on the server.

[0031] The database includes the full text of the literature, the metadata index database of the literature, and the keyword sentence database of the literature;

[0032] This step is the basic data preparation that needs to be carried out in the early stage. The data sources of the database (academic paper corpus) mainly include paper documents, digitized books, periodicals, newspapers, conference papers, dissertations, patent documents, other academic paper databases, foreign language Databases, academic paper webpages, etc.

[0033] For paper docum...

Abstract

The invention relates to a detection method on similarity of academic thesis based on a computer searching system, to provide a searching model and a similarity algorithm with pertinence through using structures and language features of the academic thesis, thereby increasing speed and efficiency of copy edit of the expert when the thesis is submitted to a higher level for approval or revision. A technical scheme of the invention comprises: an academic thesis copy detecting method based on the computer searching system, comprising the steps of: the step of building an academic thesis database on a server; the step of building a storage space of the academic thesis data based on the computer searching system; the step of building an alternation window on the server for the user to input searching condition; the step of submitting the academic thesis to be detected; building the academic thesis data ans storing according to the set searching condition; the step of comparing the academic thesis data and the data in a source database; the step of submitting the compacting result to the user by the server.

Description

technical field [0001] The invention relates to the field of computer information retrieval, in particular to the protection of intellectual property rights on a computer interconnection network, a method for detecting the similarity of academic papers through a computer retrieval system, and preventing plagiarism of academic papers. Background technique [0002] With the increasing exposure of academic misconduct in academia, plagiarism of academic papers has aroused widespread concern in society. Its severity has reached the point of "academic corruption".
