Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Before explaining the embodiment of the present invention in detail, the implementation scenarios involved in the knowledge map construction method provided by the embodiment of the present invention will be briefly introduced.

[0026] The knowledge map construction method provided by the embodiment of the present invention is applied to chat robots. Among them, a chat robot is essentially a program used to simulate human dialogue or chat, which can realize a question-and-answer function. When a user terminal asks a question, the chatbot can return an accurate answer to the user terminal, at least temporarily making the user think they are chatting with another real person. Among them, the important core of realizing the quest...

Abstract

The invention discloses a knowledge graph construction method and device and belongs to the technical field of Internet. The method comprises the following steps: based on a target language, constructing a primary knowledge graph aiming at a target object, wherein the target language is a lightweight data exchange format with the complexity which is less than that of an RDF (Resource Description Framework) language, wherein the primary knowledge graph contains various key elements needed by semantics understanding and each key element is stored in the same file; collecting industry data matched with at least one key element in the various key elements from at least one data source; adding the industry data into positions indicated by the at least one key element in the primary knowledge graph to obtain a target knowledge graph of the target object. The knowledge graph is constructed based on the lightweight target language with the complexity which is less than that of the RDF language so that the knowledge graph has relatively good readability and maintainability; the chatting effect of a chat robot can be improved. Furthermore, the knowledge graph contains various key elements which are needed by the semantics understanding and are stored in the same file, and is convenient for uniform managing.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method and device for constructing a knowledge map. Background technique [0002] Knowledge map, also known as scientific knowledge map, is called knowledge domain visualization or knowledge domain mapping map in the library and information industry. It is a series of different graphics showing the knowledge development process and structural relationship. Its carrier mines, analyzes, constructs, maps and displays knowledge and the interrelationships between knowledge. Nowadays, building a knowledge graph and applying the constructed knowledge graph to a chat robot to achieve intelligent question answering has become a widely adopted practice by those skilled in the art. [0003] When constructing a knowledge graph in related technologies, RDF (Resource Description Framework, resource description framework) language is usually used to construct a knowledge graph f...
