Affective Evaluation of Educational Lexicon in Spanish for Learning Systems

In the last years, several educational systems integrate text-based affective feedback. However, the analysis of educational lexicon from the affective perspective is limited. Previous work classified words in three categories: positive, negative or neutral. For that reason, this work proposes the construction of an educational lexicon in the Spanish and the evaluation of its affectivity using the arousal-valence scale. The educational lexicon was setting up by the suggestions of 166 undergraduate students. Then another group of 185 undergraduate students evaluated each word/phrase in a valence and arousal scale. An analysis by student gender and personality was conducted. Also, a clusterization analysis was performed to categorize the words/phrases.
