Our feature selection method picks up on indicators suggested by sociolinguistics, and it also allows for the identification of features that are not obviously characteristic of UpSpeak or Down-Speak.
some easily recognizable features include: other features are less intuitive: I'll, we'll "I'll let you know the final results soon" "Everyone is very excited […] and we're confident we'll be successful" Downspeak that is, this is "Neither does any other group but that is not my problem" "I think this is an excellent letter" We hope to improve our methods for selecting and binning features with information theoretic selection metrics and clustering algorithms.
