These classe can be defined as feature bundles (cp. table below), and thus be disambiguated also by simply discarding or selecting semantic atomic features, like +LOC or +HUM. Currently, both NER-parsers achieve around 93% correct readings, with 2% chunking errors and 5% subtype classification errors. <p>For Danish, VISL's NER-system has participated in the Nordic <a href="http://scrooge.spraakdata.gu.se/nn/">Nomen Nescio</a> research network, funded by the Nordic Council of Ministers.
