The "Affective Text" task focuses on the classification of emotions and valence (positive/negative polarity) in news headlines, and is meant as an exploration of the connection between emotions and lexical semantics. In this paper, we describe the data set used in the evaluation and the results obtained by the participating systems.

This paper describes experiments concerned with the automatic analysis of emotions in text. We describe the construction of a large data set annotated for six basic emotions: anger, disgust, fear, joy, sadness and surprise, and we propose and evaluate several knowledge-based and corpusbased methods for the automatic identification of these emotions in text.

Humor is one of the most interesting and puzzling aspects of human behavior. Despite the attention it has received in fields such as philosophy, linguistics, and psychology, there have been only few attempts to create computational models for humor recognition or generation. In this paper, we bring empirical evidence that computational approaches can be successfully applied to the task of humor recognition. Through experiments performed on very large data sets, we show that automatic classification techniques can be effectively used to distinguish between humorous and non-humorous texts, with significant improvements observed over apriori known baselines.

This paper explores the role of domain information in word sense disambiguation. The underlying hypothesis is that domain labels, such as Medicine, Architecture and Sport, provide a useful way to establish semantic relations among word senses, which can be profitably used during the disambiguation process. Results obtained at the Senseval-2 initiative confirm that for a significant subset of words domain information can be used to disambiguate with a very high level of precision.
