Valitutti, A., Strapparava, C., & Stock, O. (2005). Lexical resources and semantic similarity for affective evaluative expressions generation. Proceedings of the First International Conference on Affective Computing and Intelligent Interaction (ACII05). Beijing, China.

This is a publication.

 This paper presents resources and functionalities for the selection of affective evaluative terms. An affective hierarchy as an extension of the WordNet-Affect lexical database was developed in the first place. The second phase was the development of a semantic similarity function, acquired automatically in an unsupervised way from a large corpus of texts that allows us to put into relation concepts and emotional categories. The integration of the two components is a key element for several applications.
