Abstract
A technique for analyzing affect in which ambiguity in both emotion and natural language is explicitly represented and processed through fuzzy logic. In particular, textual information is processed to i) isolate a vocabulary of words belonging to an emotion, ii) represent the meaning of each word belonging to that emotion using multiple categories and scalar metrics, iii) compute profiles for text documents based on the categories and scores of their component words, and iv) manipulate the profiles to visualize the texts. The representation vehicle in the system is a set of fuzzy semantic categories (affect categories) followed by their respective centralities (degrees of relatedness between lexicon entries and their various categories) and intensities (representative of the strength of the affect level described by that word) called an affect set. A graphical representation of the affect set can also be used as a tool for decision making.
