Association object retrieval method based on full-text search

Abstract

The invention discloses an association object retrieval method based on full-text search, and relates to the field of metallurgical equipment. According to the technical scheme, the association objectretrieval method based on full-text search comprises the following steps: S1, establishing object data models of different types of objects; S2, establishing a relation data model of an association relation between the objects; S3, establishing full-text index of an association relation database according to a result of S2; and S4, searching association relation database index according to searchkeywords provided by a user, extracting all association objects in the relation model, and returning the association objects to the user. The association object retrieval method based on full-text search has the beneficial effects that other object information which is associated with important objects are mined deeply, and the method is a powerful tool for strengthening management of public safety. A big data analyzing technology is creatively used in the field of public safety. Compared with a universal search engine technology, the association object retrieval method based on full-text search has the advantages that a search result which takes an object as a basic unit can be acquired accurately, and the association object retrieval method is particularly suitable for application scenarios which are guided by clues among objects such as criminal investigation and criminal case cracking.

Description

technical field [0001] The invention relates to the technical field of public security, in particular to a method for searching associated objects based on full-text search. Background technique [0002] In the era of rapid Internet technology and the Internet of Everything, data has become the main carrier of information dissemination. Information generated by various devices, services, and platforms has gathered into an ocean of data. How to quickly retrieve the most relevant information from it has given birth to general search. Development of engine technology. The existing technology includes the following processes: establishing an information database and its associated index database, performing full-text search, keyword search, and classification search for search words input by users, and presenting search results in descending order of relevance. Existing technologies have better solved the needs of general search, but for some special application scenarios, such...
