Update Approach of POIs Based on Weibo Position Check-in Data
摘要
Abstract
The latest tendency of POI is critical for location-based services. The traditional POIs collecting based on on-the-spot investigation is inefficient. However, the fact is that it is unable to meet the demands of the location-based service applications. In this paper, a POIs update approach based on Weibo that involved the largest number users was proposed. Firstly, by preprocessing Weibo check-in data, coarse error points that were semantically and spatially inconsistent were removed, on the basis of which, a geo-referencing method based on Weibo check-in data in RANSAC algorithm was proposed for the purpose of fulfilling reliability of Weibo position check-in data with existing geo-database. Secondly, spatial analysis and matching modeling of check-in data set and the existing POIs database was implemented. After validation of unmatched data, extraction of valid new data as an updated POI into database was implemented. Finally, a POIs update experiment of Wuhan Jiepang position check-in data was implemented with the proposed approach. The experiment results show that the proposed approach can meet the requirements and effectively find new POIs and disappeared POIs. It provides a new way to update POIs quickly and efficiently and has a good prospect of application.关键词
