地理信息检索关键技术研究综述
Review of the key techniques of geographic information retrieval
摘要
Abstract
Most of the available digital information is associated with locations or places on the Earth.Although queries submitted to search engines often contain geographic information,the traditional information retrieval methods based on keywords are not effective,as they neglect the spatial relationship in the queries.Geographic information retrieval outputs results by spatial semantic match between queries and documents set,so it becomes a research hotspot in information retrieval and geographic information science.A framework of geographic information retrieval system is proposed,and the key techniques such as geographic knowledge base,geographic information extraction,geographic information retrieval model,hybrid index structure,and visualization of information retrieval are classified and surveyed according to this framework.Based on the comprehensive comparison and analysis of existed researches,some suggestions are presented for future research,and a lot of references are provided.关键词
