the crucial role of semantic discovery and markup in geo-temporal search
Semantic questions require semantic processing to deliver results beyond bag-of-words search. Geo-temporal search concerns search which has both geographic and temporal constraints. In particular the search for events or to answer questions about events contains, often, specificity of location (where) and time (when). NTCIR-GeoTime, the first evaluation of geo-temporal search recently presented (mid-June 2010) at the eighth NTCIR Workshop in Tokyo. The results clearly demonstrated that semantic markup for geography and time outperformed traditional IR methodologies.
