EMPIRE 2013 - 1st workshop on "Emotions and Personality in Personalized Services" http://empire2013.wordpress.com

in conjuction with UMAP 2013 (June 10-14, 2013 Rome, Italy)

While a lot of discussion has been made on filtering algorithms, and evaluation measures, few studies have stood to consider the role of emotions and personality in user models and personalized services. Characterizing the user model and the whole user experience with personalized service, by means of affective traits, is an important issue which merits attention from researchers and practitioners in both web technology and human factor fields.

Some questions motivate this workshop:

• Do affective traits (personality, emotions, and mood) influence and determine the acceptance of the personalized suggestions?
• How personality traits should be included in the user model?
• How the personalized services should be adapted to emotions and mood to increase user satisfaction?

ABSTRACT

In the pursuit of increasing the quality of personalized services, researchers started to turn to more user-centric descriptors of content and services in recent years. The advances made in affective computing, especially in automatic emotion detection techniques, paved the way for the exploitation of emotions and personality as descriptors that account for a larger part of variance in user behavior than the generic descriptors (e.g. genre of a multimedia content) used so far.

Emotions, users' responses, can be characterized in different ways. The two most common approaches are (i) the discrete basic emotions (discrete classes, e.g. joy, sadness, fear, disgust, surprise, anger) and (ii) the continuous values, in the valence-arousal-dominance space. The affective computing community has been very active in the past decade and has developed several methods for the automatic non-invasive detection of emotions via several modalities (Zeng et al., 2009).

While emotions can change pretty quickly, personality, on the other hand, describes long-lasting human traits. The most common way of describing personality is the five-factor model (openness, conscientiousness, extraversion, agreeableness and neuroticism).

Emotions and personality in personalized services (e.g., recommender systems) can be exploited in different ways at different stages in the service-usage (e.g. content consumption) chain (Tkalčič et. al, 2011). In the entry stage they can be used as a contextual parameter, as additional information to predict, assist and influence decision-making (Kahneman, 2011) or a way to diversify the personalization via the detection of serendipitous services. In the consumption stage, emotions can be used as additional tags for the characterization of the services, content and users (Jiao and Pantid, 2011), opening new research areas for modeling services and content with different lengths. Finally, emotions can be exploited also for the non-invasive acquisition of the implicit user feedback as well as for novel evaluation metrics.

So far, research on emotions and personality in personalized services has been carried out in a scattered fashion. The goal of this workshop is to provide a venue for researchers to present their work, discuss it and benefit from the interaction.
