Software - Named entity recognizers

  • Greek named entity recognizer (version 2) - currently identifies temporal expressions, person names, and organization names; see here for publications describing the recognizer
  • Balie Baseline implementation of named entity recognition.
  • English named entity recognizer - identifies/classifies entities as Person, Location, Organization and Misc (this last category relates to languages and nationalities); fast and robust; try the demo
  • UIUC NER - Java API to the UIUC NER tagger. Uses gazetteers extracted from Wikipedia, word-class model built from unlabeled text and extensively uses non-local features. Achieves 90.8F1 score on CoNLL03 shared task and is robust on other datasets.
  • Stanford NER Conditional Random Fields based NER. Also incorporates distributional similarity based features extracted from the English Gigaword corpus.
