Curse or Boon? Presence of Subjunctive Mood in Opinionated Text

In addition to the expression of positive and negative sentiments in the reviews, customers often tend to express wishes and suggestions regarding improvements in a product/service, which could be worth extracting. Subjunctive mood is often present in sentences which speak about a possibility or action that has not yet occurred. While this phenomena poses challenges to the identification of positive and negative sentiments hidden in a text, it can be helpful to identify wishes and suggestions. In this paper, we extract features from a small dataset of subjunctive mood, and use those features to identify wishes and suggestions in opinionated text. Our study validates that subjunctive features can be good features for the detection of wishes. However, with the given dataset, such features did not perform well for suggestion detection.
