Embodiment 1

[0083] A method for constructing and updating a knowledge map, comprising:

[0084] Word segmentation processing is performed on the data text of the input unstructured data or semi-structured data to determine the set of sentences; in the field of state-owned assets supervision and management, according to the type of business or system, a large amount of report data or other shared data, video, audio, Data such as text, the present invention is based on these unstructured data and semi-structured data, carries out data processing in the form of data text, word segmentation mainly divides keywords, and then divides the statement set according to keywords.

[0085] The attribute information, relationship information and entity information in the statement set are extracted; the entity information is the theme information of a data, and the relationship information indicates the coincidence degree and semantic relationship between data under different data subjects or under the ...

Abstract

The invention provides a knowledge graph construction and updating method. The method comprises the following steps: performing word segmentation processing on a data text of input unstructured data or semi-structured data, and determining a statement set; extracting attribute information, relation information and entity information in the statement set; carrying out fusion processing on the attribute information, the relation information and the entity information through co-reference resolution and entity disambiguation technologies, determining fusion information, and verifying the fusion information based on preset structured data and a third-party knowledge base; and constructing a knowledge graph according to the verified fusion information, and updating the knowledge graph.

Description

technical field [0001] The invention relates to the technical field of data management of knowledge graphs, in particular to a method for building and updating knowledge graphs. Background technique [0002] At present, in the field of state-owned assets supervision, the existing technology mainly manages through manual and systematic data classification, but the regulatory data in the field of state-owned assets supervision is mainly structured data and unstructured data, while manual and existing management The system is very difficult to process data, and the efficiency is very low. [0003] In the existing technology, the knowledge graph can provide structured semantic information that can be understood by computers and has become an indispensable and important resource for many artificial intelligence applications, but it is affected by "incompleteness". The Knowledge Graph Completion (KGC) task came into being, aiming to measure the knowledge missing in the current kn...
