A POI data update approach based on Weibo check-in data

摘要

POI updates have a direct influence on data up-to-date state, thereby affecting the data value of POI. Aimed at solving the problem facing POI rapid and accurate update, an update approach for POI based on Weibo check-in data is brought forward in this paper. Firstly, regarding to the quality issue of check-in data, a pre-processing approach with spatial registration is proposed. Then, a POI data update approach based on check-in data is discussed. At last, with experimental data from Sina Weibo, a POI update experiment is carried out, the result of which is a feasibility validation of the proposed POI update approach.
