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 invention provides a knowledge graph updating method and device, and relates to the field of artificial intelligence. The method comprises the following steps of: in response to a knowledge graphupdating request, calling a first service to obtain first identification information in a message queue, obtaining network resources corresponding to the first identification information in an HBASE database according to the first identification information, and performing knowledge extraction on the network resources to obtain triple information; calling a second service to fuse the triple information and original triple information so as to obtain fused triple information; calling a third service to process attributes and attribute values in the fused triple information to obtain intermediate triple information, and performing information fusion according to entity information in the intermediate triple information to obtain target triple information; and calling a fourth service to process the target triple information to obtain an updated knowledge graph, and writing the updated knowledge graph into the HBASE database. According to the invention, the updating efficiency of the knowledge graph can be improved, and the real-time performance of knowledge updating is ensured.

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...
