Abstract

The invention discloses a data-driven professional knowledge graph construction method. The method comprises the following steps of: performing ontology modeling according to data sources and businesscharacteristics covered by a professional field; performing knowledge extraction from a professional knowledge data source; storing the extracted professional knowledge in a mode of combining a graphdatabase, a relational database and a document database; carrying out knowledge fusion on professional knowledge collected from each data source; professional knowledge graph is constructed. According to the data-driven professional knowledge graph construction method provided by the invention, the construction of the professional knowledge graph is effectively and accurately realized, and the knowledge covering the professional field is more comprehensive under the condition that a data source is sufficiently supported.

Description

technical field [0001] The present invention relates to the field of professional knowledge map construction, in particular to a data-driven professional knowledge map construction method. Background technique [0002] Knowledge graphs can be applied to many application scenarios, such as information recommendation based on knowledge graphs in information recommendation systems, or classification based on knowledge graphs in the process of text classification. In the field of knowledge map construction, there are many research methods that build knowledge maps by constructing relational data between entities, mainly including triple-based closed-domain learning methods, and defining the relationship recognition problem as a classification problem. method. in: [0003] In the closed-domain learning method based on triples, the map relationship is defined as: <; E1, Relation, E2>;, where E1, E2 are entity descriptors, that is, entity words, and Relation is used to repr...
