Abstract

The invention discloses a code file query method and device and belongs to the technical field of data processing. The method comprises converting current query term vectors and code characteristic vectors of all code files based on historical query term vectors and a transfer matrix formed by textual characteristic vectors and code characteristic vectors of all code files, wherein the code characteristic vectors are determined according to code file code blocks; calculating the similarity between all the code files and the query terms according to current query term vectors, transformed query term vectors and transformed code characteristic vectors of all the code files and textual characteristic vectors of all the code files to obtain code file query results. By means of the method and the device, the effect of the code file structure on semantics is considered, contents and structures of the cold files are fully dug, the characteristic extraction accuracy is improved, and during the code file query, the similarity is calculated based on the textual characteristic vectors and the code characteristic vectors, and accordingly, the query accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a code file query method and device. Background technique [0002] The code base of a software system is generally composed of a large number of code files. In order to maintain the software system, it is necessary to query the code files related to the query words from the code base according to some given query words, so as to perform targeted maintenance. [0003] To this end, a paper by GiulianoAntoniol, Gerardo Canfora, Gerardo Casazza, Andrea De Lucia, and Ettore Merlo, published in IEEE Transactions on Software Engineering (the journal IEEE Transactions on Software Engineering) Vol. 28, No. 10, October 2002, entitled In the paper "Recovering Traceability Links between Code and Documentation", a method of querying code files is proposed, which specifically includes the following steps: extracting the text features of the code files according to the text information ...
