Abstract:

Knowledge graphs provide a graphical structured knowledge storage method, which can effectively manage unstructured knowledge. However, for the management of information technology project texts, general knowledge extraction methods still find it difficulty to obtain satisfactory knowledge. Therefore, an extraction framework based on dependency syntax rules that addresses the aforementioned problem by combining dependency analysis and syntax rules is proposed. The proposed framework firstly expands and integrates entities by constructing a dependency syntax structure and forms hyponymy relationships between entities. Then, it establishes relationships between entities based on their hyponymy relationships and solves the issue of multivariate relationships modeling between entities using hyperedges. Finally, the feasibility of the proposed method is verified through a case experiment.

Key words: dependency analysis, information technology, project management, knowledge graph, text mining, knowledge extraction
