Abstract
We developed a new semantic question analyser for a custom prototype assembled for participating in GikiCLEF 2009, which processes grounded concepts derived from terms, and uses information extracted from knowledge bases to derive answers. We also evaluated a newly developed named-entity recognition module, based in Conditional Random Fields, and a new world geo-ontology, derived from Wikipedia, which is used in the geographic reasoning process.
