Research on knowledge fusion method of heterogeneous data in aerospace control software

Résumé fourni par la source

The field of aerospace control software has accumulated a large amount of reusable software assets in the long-term software development process. Developers have a demand to learn and retrieve code related knowledge from different sources and types during the software development process. Software knowledge graph can represent and apply multisource heterogeneous software knowledge. The raw data for building a code knowledge graph is very extensive, including functional descriptions of functions, modules, and projects from source code data, as well as requirement specifications, code, test cases, and so on. The entities and relationships in multi-source heterogeneous data have also become more complex. To address these issues, this article constructs a knowledge graph for aerospace control software and provides software knowledge retrieval based on the software knowledge graph. The main works are designing a software knowledge graph construction framework, proposing principles and methods for extracting software knowledge entities for different types of knowledge resources, proposing a heterogeneous data knowledge fusion method, implementing a software knowledge retrieval mechanism and presenting retrieval results in a graphical visualization format. Based on the above work, a software knowledge graph construction tool for aerospace control software projects is designed and implemented. The example proves that the constructed software knowledge graph can better assist software developers in retrieving and applying software knowledge.
