Currently, vast amounts of geospatial information are offered through OGC’s services. However this information has limited formal semantics. The most common method to search for a dataset consists in matching keywords to metadata elements. By adding semantics to available descriptions we could use modern inference and reasoning mechanisms currently available in the Semantic Web. In this paper w...

Spatial information that grounds events geographically is often ambiguous, mainly because the same location name can be used in different states, countries, or continents. Spatial mentions, known as toponyms, must be disambiguated in order to understand many spatial relations within a document. Previous methods have utilized both “flat” and ontologybased ranking techniques to identify the corre...

Toponym disambiguation or location names resolution is a critical task in unstructured text, articles or documents. Our research explores how to link ambiguous locations mentioned in documents, news and articles with latitude/longitude coordinates. We designed an evaluation system for toponym disambiguation based on annotated GEOCLEF data. We implemented a node-based approach taking population ...

Toponym resolution (TR) is the task of mapping the name of a location to a spatial representation of the location referred to, such as the centroid of the location, given as latitude/longitude. While a number of systems for automating the task have been described in the literature, to date no comparative evaluation study has existed, mainly for lack of a standard benchmark (i.e., gazetteer and ...
