Extracting and Exploring the Geo-Temporal Semantics of Textual Resources

, , und . Proceedings of the International Conference on Semantic Computing, Seite 1--9. IEEE Computer Society, (August 2008)


Geo-temporal criteria are important for filtering, grouping and prioritizing information resources. This presents techniques for extracting semantic geo-temporal information from text, using simple text mining methods that leverage on a gazetteer. A prototype system, implementing the proposed methods and capable of displaying information over maps and timelines, is described. This prototype can take input in RSS, demonstrating the application to content from many different online sources. Experimental results demonstrate the efficiency and accuracy of the proposed approaches.
