Abstract
A method for inferring a location where each textual message was posted by a test user method includes partitioning an area into a plurality of sub-areas, associating textual messages posted by training users with respective sub-areas where each textual message was posted, extracting a keyword characterizing each sub-area among one or more keywords obtained from each textual message posted by the training users associated with each sub-area, constructing a feature vector of the given sub-area based on each extracted keyword, computing a transition probability for the given sub-area by time-series of location information associated with the textual messages posted by the training user, computing a plurality of scores of each location, using the feature vector, where each textual message was posted by the test user, and computing, based on the plural scores and the transition probability, time-series of locations where each textual message was posted by the test user.
