Description
This change adds the PosNegIrony transformer based on the theory described in Linda Hutcheon's paper The Complex Functions of Irony and a demo using the r/Ohio and r/Cleveland subreddit corpus'. The transformer uses a sentiment-based approach, categorizing ironic utterances by the statistical deviation from the mean sentiment of the corpus. Then it applies a simple rule-based approach to categorize an ironic utterance as positive or negative irony by taking a measure of the sentiment of the comment itself and its replies.
New PR to merge forked branch instead of forked master.
Motivation and Context
This new transformer aims to capture and score the linguistic/literature theory of positive and negative irony. It requires the corpus to have utterances labeled with "/s" for ironic comments, so it is primarily for subreddit / Reddit corpus'.
How has this been tested?
This has been tested locally in a Jupyter Notebook using the demo code provided.
