Abstract

The present disclosure relates to a method and device for constructing a knowledge base, wherein the method for constructing a knowledge base includes: acquiring a text corpus, and judging whether the text corpus contains first information according to a preset attribute description mode, and the first information includes a preset entity attribute information of the entities in the set; when it is determined that the text corpus contains the first information, the first information is extracted, and a knowledge base is constructed according to the first information and the entities corresponding to the first information. In the embodiments of the present disclosure, in the process of building a knowledge base, knowledge mining does not need to be performed manually, which saves manpower and improves the speed of building a knowledge base.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, in particular to a method and device for constructing a knowledge base. Background technique [0002] Named Entity Recognition (NER for short), also known as "proper name recognition", refers to the recognition of entities with specific meanings in text, mainly including names of people, places, institutions, and proper nouns. [0003] The nutritional value of food is a special named entity, including the name of the nutritional ingredient and its content, such as "carbohydrate", "20 grams". [0004] At present, the nutritional value of some foods is often introduced on forums, messages, blogs, news and encyclopedias. These data are of great value for the construction of a food nutritional value knowledge base. However, manual knowledge mining requires a lot of manpower and the construction of the knowledge base is slow. Contents of the invention [0005] Embodiments ...
