# Use pos tagging in bag of words

I'm using the bag of words for text classification. Results aren't good enough, test set accuracy is below 70%.

One of the things I'm considering is to use POS tagging to distinguish the function of words. How is the to go approach to doing it?

I'm thinking on append the tags to the words, for example the word "love", if it's used as a noun use:

love_noun


and if it's a verb use:

love_verb
