Abstract

The invention relates to a knowledge base construction method and device. The knowledge base construction method includes the steps that text linguistic data are obtained, and whether the text linguistic data contain first information is judged according to a preset attribute description mode, wherein the first information includes attribute information of entities in a preset entity set; when it is determined that the text linguistic data contain the first information, the first information is extracted, and a knowledge base is constructed according to the first information and entities corresponding to the first information. According to the embodiment of the knowledge base construction method and device, in the process of constructing the knowledge base, it is unnecessary to perform knowledge mining in a manual mode, in this way, labor is saved, and the construction speed of the knowledge base is increased.

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 meaning 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 o...
