Abstract

The invention discloses a method and system for extracting a knowledge graph from software project data and answering the knowledge graph. The method comprises the following steps that for each type of software project data in a software project database, entities and an incidence relation between entities are extracted from the type of the software project data to be stored in a corresponding graph database; based on a traceability correlation technology of software data, correlation processing is carried out on the data in each graph database, and the correlation between entities of different types of software project data is obtained; and a corresponding edge is added into each graph database according to the incidence relation between entities of different types of software project data, and the entities with different sources are connected to generate the knowledge graph of the software project data; for the input natural language query statement, a matched communication sub-graphis inquired from the knowledge graph to serve as an answer. By virtue of the method and system, the problems of data correlation deletion, serious information isolation and difficulty in connection query and analysis of the software project are solved.

Description

technical field

[0001] The invention relates to a method and system for extracting a knowledge map from software project data and asking and answering questions, belonging to the technical field of computer software. Background technique

[0002] Reuse of existing large-scale software projects is an important way to improve software productivity and software quality of software enterprises. The premise of successful software reuse is that the reuser can quickly and correctly learn and understand a large amount of relevant knowledge in software projects, such as domain concepts, system architecture, interface design, change history, and so on. This knowledge is contained in the multi-source heterogeneous data generated during the entire life cycle of a software project, such as: source code, requirements documents, design documents, version library, defect library, email records, forum discussions, technical blogs, etc.

[0003] At present, a large number of researchers in t...
