'''[[Software]] - Named entity recognizers'''

*[http://balie.sourceforge.net/ Balie] Baseline implementation of named entity recognition.
*[http://gate.ac.uk/ GATE] includes the ANNIE gazeteer-based NER subsystem.
*[http://www-tsujii.is.s.u-tokyo.ac.jp/GENIA/tagger/ GENiA]- part-of-speech tagging, shallow parsing, and named entity recognition for biomedical text. C++, BSD license.
* [http://www.aueb.gr/users/ion/software/GREEK_NERC_v2.tar.gz Greek named entity recognizer (version 2)] It currently identifies temporal expressions, person names, and organization names; see [http://www.aueb.gr/users/ion/publications.html here] for publications describing the recognizer.
*[http://www.alias-i.com/lingpipe/ LingPipe]
*[http://nlp.stanford.edu/software/CRF-NER.shtml Stanford NER] Conditional Random Fields based NER. Also incorporates distributional similarity based features extracted from the English Gigaword corpus.
*[http://l2r.cs.uiuc.edu/~cogcomp/asoftware.php?skey=FLBJNE 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 [http://cogcomp.cs.illinois.edu/page/demo_view/NER Illinois-NER-Demo]
* [http://l2r.cs.uiuc.edu/~cogcomp/asoftware.php?skey=NE 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 [http://l2r.cs.uiuc.edu/~cogcomp/ne_demo.php demo]

* [http://www.wikimeta.org Wikimeta] is an API service based on various methods (rules, CRF) for named entity extraction and linking to the semantic web. It works trough on-line web form and also provide Part of Speech tagging.
