Summary]
We proposed a system for high-speed retrieval of posts about various POIs by maintaining the results of prior searches at various locations as an index in spatio-temporal Twitter searches that include POIs (Point-of-Interest) such as place names and facility names. We also verified through subjective evaluation experiments that the diversity of search results can be used as a reference for users’ behavior when they go out.
