Embodiment

[0054] This embodiment describes the process of adopting a source code author identification method based on a deep belief network according to the present invention, such as figure 1 shown.

[0055] From figure 1 It can be seen that the specific steps are as follows:

[0056] Step 1), construct the source code data set by the source code data acquisition module, and preprocess the source code data;

[0057] Grab source code from a source code website and save it to your local computer. Wherein, the source code website can be a github website, and the URL is https: / / github.com / ;

[0058] Preprocess the collected source code, obtain the source code author and the source code file collection written by him;

[0059] Step 2), for the source code file, the source code feature extraction module adopts the method based on the continuous n-gram code segment model to extract the source code feature;

[0060] A code segment is a string of fields in source code separated by blanks,...

Abstract

The invention discloses a source code author identification method based on a deep belief network, and belongs to the field of Web mining and information extraction. The method includes the followingsteps of constructing a source code data set, and preprocessing source code data; extracting source code features based on a continuous n-gram code segment model; training a deep belief network modelbased on a training source code file sample; using the trained deep belief network model to identify an author of an source code file, and outputting an author identification result of the source codefile. The method converts a source code author identification problem into a classification problem, and identifies the identity of the author of the source code through the deep belief network, so that the performance and efficiency of identification of author identity are improved, and the method has broad application prospects in the fields of information retrieval, information security, computer forensics and the like.

Description

technical field [0001] The invention relates to a source code author identification method based on a deep belief network, which belongs to the field of Web mining and information extraction. Background technique [0002] Existing source code author identification methods mainly include sorting methods, statistical analysis methods, shallow structure machine learning classification methods, and similarity measurement methods. [0003] Source code author identification based on sorting methods includes sorting methods based on information retrieval and sorting methods based on author portraits. The core idea of ​​the sorting method based on information retrieval is to use information retrieval techniques to identify the author of the source code. First, convert the source code into a string sequence such as operators and keywords; secondly, convert the string sequence into an n-gram sequence; then, build an index for all source code; finally, retrieve the source code whose a...
