Lecture Notes in Computer Science- P9:This year, we received about 170 submissions to ICWL 2008. There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings. The authors of these accepted papers came from many different countries. | 30 M. Leontidis C. Halatsis and M. Grigoriadou Emotions Mood and the OCC Model Although many efforts have taken place there is not an explicit definition for the emotion. It is easy to feel but it is hard to describe it. According to Scherer 19 emotion is the synchronized response for all or most organic systems to the evaluation of an external or internal event. Nevertheless various attempts have been made but the cognitive theory of emotions known as OCC model which formulated by Ortony Cl ore and Collins 16 keeps a distinctive position among them. The three authors constructed a cognitive theory of emotion that explains the origins of emotions describing the cognitive processes that elicit them. The OCC model provides a classification scheme for 22 emotions based on a valence reaction to events objects and agents. Events are situations which are interpreted by people in a certain way. Objects are material or abstract constructions. Agents can be human beings animals artificial entities which represent humans or animals and software components which act in a specific way. The origin of emotions relate to the subject s perspective against Goals Standards and Attitudes. The events are evaluated in terms of their desirability according to the goals of the subject. Standards are used to evaluate actions of a subject and objects are evaluated as appealing depending on the compatibility of their attributes with subject s attitudes. Emotion is analogous to a state of mind that is only momentary. Mood is a prolonged state of mind resulting from a cumulative effect of emotions 19 . Mood differs from the emotion because it has lower intensity and longer duration. It can be consequently considered that mood is an emotional situation more stable than emotions and more volatile than personality. Based on this definition we categorize mood into two categories named positive and negative. We consider that the student has either a positive mood when he feels emotions like .
