Just to clarify, *UIMA* itself doesn't specify any part-of-speech tags. However, it appears that the annotators Jeff is using with Apache Solr (and, as far as I know, it may be possible to configure SOLR to use several different kinds of annotators in UIMA pipelines) specify some kind of type system. I've changed the "Subject" line for this email thread to reflect this :-) -Marshall On 8/1/2013 11:09 PM, Anuj Kumar wrote: > AFAIK, it is based brown corpus- > http://en.wikipedia.org/wiki/Brown_Corpus#Part-of-speech_tags_used > > Also, see Penn Treebank- > http://www.ling.upenn.edu/courses/Fall_2003/ling001/penn_treebank_pos.html > The guide is available here- http://www.cis.upenn.edu/~treebank/ > > - Anuj > > On Thu, Aug 1, 2013 at 10:05 PM, Jeffery Yuam wrote: > >> Is there online resource that explains the meaning of all pos tags used in >> UIMA? >> >> Recently I am using uima in Solr, and trying to understand the meaning of >> pos >> tags such as ap, ppl, ppls, ppo, pps, ppss. >> >> Tired google search, but no luck. >> >> Is there online resource that explains all pos tags used in UIMA? >> Thanks in advance. >> >>
