Abstract

The embodiment of the invention discloses a domain knowledge base construction method and device, and the method comprises the steps: obtaining entity data according to a preset expert knowledge base,and the entity data comprises the concepts and attributes of entities and the relation between the entities; performing text information extraction on the entity data by using a preset extraction technology, and taking the extracted text information as ontology data; and carrying out knowledge construction on the ontology data by adopting the created reasoning knowledge base, and forming a new domain knowledge base according to new knowledge obtained by knowledge construction. Through the scheme of the embodiment, a knowledge base which is low in cost and based on knowledge reasoning is established, an automatic decision-making process is realized, the data quality and flexibility of the map are improved, and the data governance difficulty and cost are reduced.

Description

technical field [0001] Embodiments of the present invention relate to data processing technology, in particular to a method and device for constructing a domain knowledge base. Background technique [0002] (1) Ontology technology [0003] The research on ontology is very extensive, and the most commonly used classification method is to divide these numerous ontology into five types according to the subject of ontology application: domain ontology, general or common sense ontology, knowledge ontology, linguistics ontology and task ontology. According to the level and domain dependence of ontology, Guarino et al. divided it into four categories: top-level ontology, domain ontology, task ontology and application ontology. [0004] 1. Top-level ontology: research on general concepts and the relationship between concepts, such as space, time, events, behaviors, etc., has nothing to do with specific applications and is completely independent of limited fields, so it can be share...
