I am looking forward to know how could I use POS tags as the features. Adding partOfSpeechDetails after tokenizing the document has tagged every word with its respective POS. But how could I take these tags as the features to fed into a classifier?
As an example, for the sentence, "hello. how are you?", I got the POS details as the following:
Token DocumentNumber SentenceNumber LineNumber Type Language PartOfSpeech
_______ ______________ ______________ __________ ___________ ________ ______________
"hello" 1 1 1 letters en interjection
"." 1 1 1 punctuation en punctuation
"how" 1 2 1 letters en adverb
"are" 1 2 1 letters en auxiliary-verb
"you" 1 2 1 letters en pronoun
"?" 1 2 1 punctuation en punctuation
Now, how could I take the PartOfSpeech columns as a feature for the sentence? And do u shed some light on how many part of speeches are avilable in Matlab?
I am looking for your advice in this regard.
