A geo-temporal Web gazetteer integrating data from multiple sources

This paper presents a geo-temporal gazetteer Web service that provides access to names of places and historical periods, together with the associated geotemporal information. Within the DIGMAP project, this gazetteer serves as the unified repository of geographic and temporal information, assisting in the mining of geotemporal expressions over text, as well as in resource searching and indexing. We describe the data integration methodology and some of the applications that use the gazetteer. Initial evaluation results show that the proposed system can adequately support several tasks related to geotemporal information extraction and retrieval.
