Fredric C. Gey, Ray R. Larson, Noriko Kando, Jorge Machado, Tetsuya Sakai · 2010
For the NTCIR Workshop 8 we organized a Geographic and Temporal Information Retrieval Task called “NTCIR GeoTime”. The focus of this task is on search with Geographic and Temporal constraints. This overview describes the data collections (Japanese and English news stories), topic development, assessment results and lessons learned from the NTCIR GeoTime task, which combines GIR with time-based search to find specific events in a multilingual collection. Eight teams submitted Japanese runs (including unofficial three teams who provided runs to expand the pools) and six teams submitted English runs. One team participated in both Japanese and English.
