I am trying to test one name entity tagger.
I am using NLTK's
which requires data in Brown corpus's tagged_sents() format.
I was looking for a free benchmark entity tagged corpus in the said format of Brown corpus.
I could not find anyone.
I found conll2000 in NLTK itself from which I am trying to extract data as (w,c) format as in http://pastebin.com/AttNEbSe and test.
I am thinking of an alternative. I found two online NERs, like Stanford Online NER Cognitive Computing Group NER
If I paste data generate NER like http://pastebin.com/x1bVW6u7 and create data in said format, may I use either of them as benchmark data?
