The invention provides a knowledge graph-based search method and device, a computer device and a storage medium. The method comprises the steps of receiving a first query statement input by a user; analyzing the first query statement to obtain at least one first keyword and obtain attributes of the first keyword; searching for a target keyword having the same attribute as the first keyword and thecorresponding attribute in a preset keyword-attribute table, and judging whether a second keyword associated with the target keyword exists or not, wherein the attribute table is a table set according to a preset attribute dimension; if yes, determining from the keyword; determining a second keyword and an attribute of the second keyword in the attribute table; and respectively searching in the knowledge graph according to the target keyword, the attribute of the target keyword, the second keyword and the attribute of the second keyword. Search is more accurate, and the quality of search recall results is also improved.
Description
technical field [0001] The present application relates to the technical field of knowledge graphs, and in particular, to a knowledge graph-based search method, apparatus, computer equipment and storage medium. Background technique [0002] The current knowledge graph search only performs word segmentation for the search query words (query), and recalls the search results for the split words respectively. The quality of the recall results is not high and cannot meet the query needs of users. SUMMARY OF THE INVENTION [0003] The main purpose of this application is to provide a search method, device, computer equipment and storage medium based on knowledge graph, aiming at solving the problem of low quality of recall results. [0004] In order to achieve the above purpose, the present application provides a search method based on knowledge graph, comprising the following steps: [0005] receiving the first query statement input by the user; [0006] Parsing the first query...
