Problems solved by technology

The main reason is that Chinese is not as fixed in format as English, and the expression is simple and does not require word segmentation. The structure of Chinese is complex, and the expression forms are diverse and need word segmentation.

Embodiment 1

[0035] The system provided by the present invention mainly includes four modules: a document processing module, an entity and relationship extraction module, a knowledge map generation module and a knowledge database module in various fields. The specific workflow is to preprocess the input document through the document processing module, then extract the entities and relationships in the document through the entity and relationship extraction module, and finally send the extracted entities and relationships to the knowledge map generation module to build complete knowledge The graph is returned to the user, and the data in the knowledge graph generation module is updated. Below is a detailed introduction to each module.

[0036] The knowledge database module of various fields excavates the knowledge data of various fields from the online encyclopedia, and then saves them to construct the knowledge map of the document. According to the classification of the encyclopedia, the ...

Abstract

The invention provides an automatic Chinese text knowledge graph construction method. When the automatic Chinese text knowledge graph construction method is employed more frequently, text libraries, relational databases and entity libraries related to various fields are enriched gradually, so that better knowledge graph construction effect is achieved.

Description

technical field [0001] The present invention relates to the field of knowledge graph construction, and more specifically, to a method and system for automatically constructing a Chinese text knowledge graph. Background technique [0002] The knowledge map is a kind of knowledge organization structure, which is shaped like a map, hence the name. A typical knowledge graph usually contains a series of concepts, instances and relations. Compared with plain text, the knowledge graph is structured. The nodes in the graph are represented as concepts or instances, and the edges between nodes represent the relationship between the two, so text is usually regarded as unstructured . The application of knowledge graph is very extensive and can be applied to many fields such as semantic search, intelligent question answering, knowledge engineering, data mining and digital library. In general, the construction of knowledge graphs can be divided into manual construction, automatic const...
