In this way, although the constructed knowledge map can cover a wide range, for a batch of samples, not only the data of each sample needs to be known, but also the corresponding category label needs to be known, which is very dependent on the data source containing the label. higher cost

Abstract

The embodiment of the invention discloses a knowledge graph completion method and device, a computer device and a storage medium. The method comprises the following steps of obtaining the knowledge information to be processed; extracting a named entity and an association relationship from the to-be-processed knowledge information according to a preset first extraction rule; generating an entity tuple according to the named entity and the association relationship; and supplementing the entity tuples to a knowledge graph. Via the above method, the obtained data source only needs a small part ofannotations; the grammar style is generated according to the labeled part of data, and the unlabeled data is subjected to information extraction through the grammar style, so that the dependency on labeling in the data source can be effectively reduced, the labor cost and the time cost for adding labeling to the data source are reduced, and the efficiency and the accuracy of knowledge graph completion are improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a knowledge graph complementing method, device, computer equipment and storage medium. Background technique [0002] A knowledge graph is a knowledge cluster organized in the form of a graph in knowledge engineering, which consists of different types of entities as nodes and relationships as edges connecting nodes. In the knowledge graph, an entity refers to an objective object in the real world, or an abstract concept in human thought, and a relationship describes the actual relationship between two entities. [0003] In known knowledge graphs, entity types include people, events, organizations, places, etc., and the types of relationships between them are also very diverse. Different entity types pay attention to different relationships. For example, for person entities, common relationships include relatives and friends; for people and organizations, c...
