Learning multilingual named entity recognition from Wikipedia

dataset
posted on 03.10.2017 by Joel Nothman, Nicky Ringland, Will Radford, Tara Murphy, James R Curran
This is the data associated with Joel Nothman, Nicky Ringland, Will Radford, Tara Murphy and James R. Curran (2013), "Learning multilingual named entity recognition from Wikipedia", Artificial Intelligence 194 (DOI: 10.1016/j.artint.2012.03.006). A preprint is included here as wikiner-preprint.pdf

This data was originally available at http://schwa.org/resources (which linked to http://schwa.org/projects/resources/wiki/Wikiner).

The .bz2 files are NER training corpora produced as reported in the Artificial Intelligence paper. wp2 and wp3 are differentiated by wp3 using a higher level of link inference. They use a pipe-delimited format that can be converted to CoNLL 2003 format with system2conll.pl.

nothman08types.tsv is a manual classification of articles first used in Joel Nothman, James R. Curran and Tara Murphy (2008), "Transforming Wikipedia into Named Entity Training Data", In Proceedings of the Australasian Language Technology Association Workshop 2008. http://aclanthology.coli.uni-saarland.de/pdf/U/U08/U08-1016.pdf

popular.tsv and random.tsv are manual article classifications developed for the Artifiical Intelligence paper based on different strategies for sampling articles from Wikipedia in order to account for Wikipedia's biased distribution (see that paper). scheme.tsv maps these fine-grained labels to coarser annotations including CoNLL 2003-style.

wikigold.conll.txt is a manual NER annotation of some Wikipedia text as presented in Dominic Balasuriya and Nicky Ringland and Joel Nothman and Tara Murphy and James R. Curran (2009), in Proceedings of the 2009 Workshop on The People's Web Meets NLP: Collaboratively Constructed Semantic Resources (http://www.aclweb.org/anthology/W/W09/W09-3302).
