Abstract

The present invention relates to a database retrieval method, system and equipment based on entity attribute relationship. The method includes: S1. receiving the query content input by the user from the application interface; S2. judging the query mode according to the query content, and the query mode includes Semantic query, relational query and direct query; S3. If it is a semantic query, provide a unified structured semantic query interface, convert the query content into a standard data format, and perform entity and attribute analysis on the query content through a preset algorithm , the analysis and processing of the relationship, if it is a relational query, then execute step S4, if it is a direct query, then execute step S4 or S5; S4. compare the query content with the triple data in the preset database; S5. obtain The retrieval result of the preset database, and return the retrieval result to the application interface. The invention is based on the data organization mode of entities, attributes and relationships, which is convenient for data association analysis and provides a realization basis for data mining.

Description

technical field [0001] The invention relates to the field of database retrieval, in particular to a database retrieval method, system and equipment based on entity attribute relationship. Background technique [0002] Semantic query refers to the process of retrieving knowledge from the knowledge base on the basis of knowledge organization. It is an intelligent retrieval method based on the knowledge organization system that can realize knowledge association and concept semantic retrieval. In the early days of image retrieval, the characteristics of images were described by text description, such as the author, age, genre, and size of paintings. After that, image retrieval technology that analyzes and retrieves the content semantics of images, such as image color, texture, layout, etc., appears. Text-based image retrieval generally uses keywords to query images. For example, if you want to find pictures of landscapes, you can enter "landscape painting"; if you want to find ...
