Community-based geospatial tag estimation

Wei Niu, James Caverlee, Haokai Lu, Krishna Kamath
2016 2016 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining (ASONAM)  
This paper tackles the geospatial tag estimation problem, which is of critical importance for location-based search, retrieval, and mining applications.  ...  However, tag estimation is challenging due to massive sparsity, uncertainty in the tags actually used, as well as diversity across locations and times.  ...  Evaluating the Community-based Approach We now turn to investigating the quality of conceptual community-based tag estimation, before turning in the following section to comparing the community-based estimator  ...
