Embodiment Construction

[0048] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0049]Before introducing the solution for building a knowledge graph based on structured data provided by the present invention, a brief introduction to the concept of a knowledge graph is given. The knowledge graph aims to describe various entities or concepts that exist in the real world, and each entity or concept is identified by a globally unique ID (Identity). Each attribute-value pair is used to describe the intrinsic charac...

Abstract

The invention provides a knowledge graph construction method and device based on structural data. The method comprises the steps of obtaining one or more structural data containing entity names and corresponding entity attribute information, extracting the mapping relation between the entity names and the entity attribute information contained in the structural data, and generating a corresponding data structural pair; using the generated data structural pair as knowledge graph data items to be stored. A knowledge graph is constructed based on the structural characteristics of the structural data, the framework of data items in the knowledge graph is made to contain the entity names and the corresponding entity attribute information, and the entity attribute information can be visually and accurately used as a research result to be provided for a user when a search service is externally provided based on the structural data of the knowledge graph.

Description

technical field [0001] The present invention relates to the field of information search, in particular to a method and device for constructing a knowledge graph based on structured data, and a method and device for providing search by using the structured data of the knowledge graph. Background technique [0002] With the rapid development of information technology, today's society has entered the era of information explosion, and people increasingly rely on the Internet to find the information they need. Therefore, retrieval has become an indispensable part of people's work and life. People usually use search engines to search. Search engines refer to collecting information from the Internet according to certain strategies and using specific computer programs. The system by which information is presented to the user. [0003] At present, when search engines collect information on the Internet, they mainly collect data through the link relationship between web pages, so the...
