Hi all. Thank you very much for your suggestion. I have learned HMMs in the class of NLP. Sorry for that I don't know that how HMMs are used in Apertium to perform part-of-speech disambiguation. I will take time to learning soon. I think I can use the phoneme based approaches. the problem I need to deal with is: how to deal with the European languages besides Asian languages. (a) Apertium (by installing it, studying its PoS tagger, etc.); (b) the documentation available about Apertium part-of-speech tagging; (c) the problem of "hidden" unknown words, and that makes a proposal to detect these with an indication
Someone who has suggestion to me please feel free to tell me ! Thank you very much ! I think this topic is quite interesting Thank you very much Chen Xiajian 2011-04-03 xmujay 发件人： Jimmy O'Regan 发送时间： 2011-04-03 09:23:27 收件人： ftyers; apertium-stuff 抄送： 主题： Re: [Apertium-stuff] Detect 'hidden' unknown words inApertium_chenxiajian On 3 April 2011 02:01, Francis Tyers <fty...@prompsit.com> wrote: > El ds 02 de 04 de 2011 a les 21:21 +0100, en/na Jimmy O'Regan va > escriure: >> On Saturday, 2 April 2011, Mikel Forcada <m...@dlsi.ua.es> wrote: >> > >> > Dear Xiajian, >> > >> > I think you haven't taken your time to study how HMMs are used in >> > Apertium to perform part-of-speech disambiguation.

No, you can evaluate by subtracting existing analyses, not just by adding new ones. -- <Leftmost> jimregan, that's because deep inside you, you are evil. <Leftmost> Also not-so-deep inside you. ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ Apertium-stuff mailing list Apertium-stuff@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/apertium-stuff
