基于时空感知能力的农业信息搜索技术研究
Agricultural information search technique research based on space-time perception ability
摘要
Abstract
[Objective]This research aimed to provide key technology and prototype system for professional agricultural information search engine development with temporal perception, and ultimately to achieve higher recall rate, query efficiency rate, and excellent user experience. [Method]Agricultural search was used as the study subject, through the search engine system structure and the research and analysis of key technology and data structure, then referencing the existing segmentation search technology, location search technology, and gazetteer search technology, agricultural search was joined onto the independent position index on agricultural topics search and query methods in order to achieve positional (regional) search retrieval. [Result]This technology application formed spatial perception ability for the agricultural information search prototype system. After testing the prototype system, the position accuracy can reach above 80%.[Conclusion ]This technology application and promotion could improve the agricultural information system usage efficiency and achieve better application effect.关键词
