data mining comments

I have a dataset of comments from the group in the social network and I do Text Mining of it.
I conducted a sentiment analysis,
made a word cloud,
found frequency words,
found associations with important words,
defined daily activity and
average length of the discussions.
What I can do more? Any ideas?
I use R and Python.
Thank you

you need to train a separate dataset manually.. thousands of observations. someone in the world might have done something like that hopefully.

I dont know the structure of the website but may be if you have the user data, may be you can find influencers (or power users)?. Whose posts irrespective of quality receive a lot of attention. If say Mark Zuckerberg is going to comment on this thread. He brings a lot more users with him than any other ordinary person. If you have the data, go for it.
