Title
(EN) Retrieval system and method for improving performance through structured information pre-filtering deploy and control library
(ZH) 通过结构化信息前过滤布控库提升性能的检索系统和方法
Abstract
(EN)
The invention discloses a retrieval system for improving performance through a structured information pre-filtering deploy and control library. The retrieval system comprises a retrieval database, atleast one structural feature recognition module, a unique feature recognition module, a pre-filtering module and a retrieval module. The retrieval database comprises a plurality of data, and each datacomprises a unique feature and a structural feature. Retrieval request information is input into the structural feature recognition module and the unique feature recognition module. The structural feature recognition module extracts structural information in the retrieval request information. The unique feature recognition module extracts unique information in the retrieval request information. The front filtering module performs front filtering on the retrieval database according to the structured information and forms an intermediate database. The retrieval module retrieves the intermediatedatabase according to the unique information to form a retrieval result. The invention further discloses a retrieval method for improving the performance through the structured information pre-filtering deploy and control library. According to the invention, time consumption and false alarm rate can be reduced.
