Classification Of Emotions in Internet Chat: An Application of Machine Learning Using Speech Phonemes Export

@techreport{holzman03classification, abstract = {This article reports our progress in the classification of expressions of emotion in network-based chat conversations. Emotion detection of this nature is currently an active area of research [8] [9]. We detail a linguistic approach to the tagging of chat conversation with appropriate emotion tags. In our approach, textual chat messages are automatically converted into speech and then instance vectors are generated from frequency counts of speech phonemes present in each message. In combination with other statistically derived attributes, the instance vectors are used in various machine-learning frameworks to build classifiers for emotional content. Based on the standard metrics of precision and recall, we report results exceeding 90\% accuracy when employing k-nearest-neighbor learning.
