Software - Named entity recognizers

  • Balie Baseline implementation of named entity recognition.
  • GATE includes the ANNIE gazeteer-based NER subsystem.
  • GENiA- part-of-speech tagging, shallow parsing, and named entity recognition for biomedical text. C++, BSD license.
  • Greek named entity recognizer (version 2) It currently identifies temporal expressions, person names, and organization names; see here for publications describing the recognizer.
  • LingPipe
  • Stanford NER Conditional Random Fields based NER. Also incorporates distributional similarity based features extracted from the English Gigaword corpus.
  • Illinois NER Java-based Illinois 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 the CoNLL03 shared task data and is robust on other datasets. Try the LBJ-NER-Demo
  • Older version of Illinois NER - identifies/classifies entities as Person, Location, Organization and Misc (this last category relates to languages and nationalities); fast and robust; try the demo
