I have 2 English text corpora. One is people talking about topic "A" while other is people talking about topic "B".
From a language point of view - the way people express themselves on topic "A" is different from topic "B". I want to understand and analyze how is language of one corpus is similar/disimilar from the language in the other corpus (both qualitatively and quantitatively). I am aware of only the following techniques:
I am aware of only -
- word frequency counts
- KL divergence
- sentiment analysis
What other techniques are there in the literature ?
