Combining Parallel Treebanks and Geo-Tagging

This paper describes a new kind of semantic annotation in parallel treebanks. We build French-German parallel treebanks of mountaineering reports, a text genre that abounds with geographical names which we classify and ground with reference to a large gazetteer of Swiss toponyms. We discuss the challenges in obtaining a high recall and precision in automatic grounding, and sketch how we represent the grounding information in our treebank.
