Information structure, topic-comment, topicalisation, and sentiment analysis

I have run some experiments over the past year to figure out what happen if we weighted attitudinal items differentially according to their position in the utterance, thinking that topicalisation and the vanilla topic-comment structure might have something to say about which items are the most interesting. Yes, they do, but how to make use of it is not entirely clear.

A brief report of those experiments is here.
