چکیده

We retrieved topics that contained the geographic and temporal information at NTCIR-8 GeoTime task. Employing morphological analysis, temporal and geographic information are extracted from GeoTime collection. The index that represents a geographic hierarchy is made from the geographic information. In the experiment, we confirmed that the effect of the geographic hierarchical index when topics included term of wide area region.
