Abstract

The invention provides a method and device for establishing a knowledge graph based on user annotation information. The method comprises the steps that the user annotation information for a specific entity in a network is collected, a structural data pair of the specific entity and the annotation type attribute information is generated according to the user annotation information, and the knowledge graph is established with the structural data pair as knowledge entries. According to the method and device, when a search service is provided for the outside based on the structural data pair, the annotation attribute information can visually and accurately serve as a search result to be provided for a user, and therefore the search efficiency is improved, and the user search experience is improved.

Description

Technical field [0001] The invention relates to the field of information search, in particular to a method and device for constructing a knowledge graph based on user annotation information, and a method and device for providing search based on the knowledge graph. Background technique [0002] With the rapid development of information technology, today's society has entered an era of information explosion. People are increasingly using 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 collect information from the Internet according to certain strategies and use specific computer programs. After the information is organized and processed, it provides users with search services, which will be related to user searches. The system by which information is presented to users. [0003] In related technologies, such as film and television retrieval, m...
