Datasets of conversations of people in text format which have been labelled positive and negative

Question

I am currently doing a project on sentiment analysis. For this, I am searching for datasets of conversations of people in text format which have been labelled positive and negative. Can someone give me the links of such data sets.

Answer 1

There are some good data sets with sentiment tags, but they are not from conversations. Check out this answer to see some of them.

Another good corpus for sentiment analysis that is also used for question answering (QA) is MPQA.

Answer 2

A good dataset is downloadable from Stanford CoreNLP website (http://nlp.stanford.edu/sentiment/, then look at the box "Dataset downloads" on the right). This dataset is labelled at different levels (single word, phrases, entire sentences): if you only look for a sentence-level annotation you can simply take the outermost label of every sentence.
