Abstract

The invention discloses question and answer method, system and device based on knowledge graph and storage medium. The method comprises the steps: receiving a questioning statement inputted by a user,carrying out the word segmentation extraction of the questioning statement, and obtaining questioning information; if it is judged that one piece of information in the questioning information is correspondingly matched with one piece of information in any piece of reference triple information in the knowledge graph, adding the reference triple information to a preset attention stack; assembling aquery statement according to the reference triple information and the questioning information in the attention stack; and querying the knowledge graph by adopting the query statement to obtain a questioning answer, and returning the questioning answer to the user. The questioning answers can be returned to the user according to the questioning sentences of the user, and the accuracy of multiple rounds of questioning and answering can be higher.

Description

technical field [0001] The present invention relates to the technical field of knowledge graphs, and in particular, to a question and answer method, system, device and storage medium based on knowledge graphs. Background technique [0002] Knowledge graph technology describes conceptual entities and their relationships in the objective world in a structured form, expresses Internet information in a form closer to the human cognitive world, and provides a way to better organize, manage and understand massive amounts of Internet information. Ability. Knowledge graph relational concepts, entities and their relationships, where entities are things in the objective world, and concepts are generalizations and abstractions of things with the same properties. Knowledge graphs are usually represented in the form of triples, that is, G=(E, R, S), where E={e1, e2, e3,...,en} is the set of entities in the knowledge base, including |E| different entities; R={r1, r2, ..., rn} is the rel...
