摘 要: 认知空间位置,分享空间信息是在大尺度空间范围下,空间定位的最基本过程。在路径指引的过程中加以地标辅助解释有助于提高路人的认知程度。因此,如何以一种客观、高效、便捷、精确的方式提取不同显著的地标成为相关领域的热点。本文提出一种基于微博签到数据、微信热度以及搜狗热度的地标显著度模型的构建方法,以服务于导航数据库构建、地标补充、市政规划等。 Cognizing the spatial location and sharing the space information are the basis of spatial positioning in large scale space.In route navigation,the spatial cognition can be greatly improved with the help of landmarks.Therefore,many studies have been focusing on how to extract significant landmarks in an efficient and effective way.This study develops a model to evaluate the landmark saliences based on Weibo check-in data,Wechat index and Sougou index,which is helpful to find additional important landmarks,build navigation database,and improve municipal planning,etc..
