Problems solved by technology

However, since there are more than ten data processing modules in the HDFS-based knowledge graph construction architecture, each data processing module runs serially through scripts, and it takes a day or even several days to run a complete process. For fast entities, their information cannot be updated to the knowledge map in time, and the real-time performance is poor
At the same time, the storage structure of HDFS determines that a single piece of data cannot be modified according to the key.

Abstract

The disclosure provides a method and a device for updating a knowledge graph, and relates to the field of artificial intelligence. The method includes: in response to a knowledge map update request, calling the first service to obtain the first identification information in the message queue, obtaining the network resources corresponding to the first identification information in the HBASE database according to the first identification information, and performing knowledge on the network resources Extract to obtain triplet information; call the second service to fuse the triplet information with the original triplet information to obtain the fusion triplet information; call the third service to merge the attributes and attribute values ​​in the triplet information Process to obtain the intermediate triplet information, and perform information fusion according to the entity information in the intermediate triplet information to obtain the target triplet information; call the fourth service to process the target triplet information to obtain the updated Knowledge map, and write the updated knowledge map into the HBASE database. The present disclosure can improve the updating efficiency of the knowledge graph and ensure the real-time performance of knowledge updating.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, in particular, to a method for updating a knowledge graph, a device for updating a knowledge graph, a computer storage medium, and electronic equipment. Background technique [0002] Knowledge Graph is the successful application of knowledge engineering, an important branch of artificial intelligence, in a big data environment. Together with big data and deep learning, knowledge graph has become one of the core driving forces for the development of the Internet and artificial intelligence. A knowledge graph is a structured semantic knowledge base for describing concepts in the physical world and their interrelationships in a symbolic form. Its basic unit is the "entity-relationship entity" triplet, as well as entities and their related attribute-value pairs. Entities are connected to each other through relationships to form a networked knowledge structure. [0003] Usual...
