Abstract
The participation of the University of Hildesheim focused on the monolingual German and English tasks of GeoCLEF 2007. Based on the results of GeoCLEF 2005 and GeoCLEF 2006, the weighting and expansion of geographic Named Entities (NE) and Blind Relevance Feedback (BRF) were combined and an improved model for German Named Entity Recognition (NER) was evaluated. Post submission experiments are also presented.. A topic analysis revealed a wide spread of MAP values with high standard deviation values. Therefore further development will lie in the field of topic-adaptive systems. © 2008 Springer-Verlag Berlin Heidelberg.
