Since only specific kinds of data will do, one of the most difficult parts of the training process can be finding enough relevant data.
Sentiment Analysis is the process of ‘computationally’ determining whether a piece of writing is positive, negative or neutral. Both rule-based and statistical techniques … I recommend using 1/10 of the corpus for testing your algorithm, while the rest can be dedicated towards training whatever algorithm you are using to classify sentiment.
