In this paper we present the results of three investigations of our broad research on the usage of affect and personality in recommender systems. We improved the accuracy of a content-based recommender system with the inclusion of affective parameters in user and item modeling. We improved the accuracy of a content filtering recommender system under the cold start conditions with the introducti...

This article describes the required parameters for the development of the socio-Affective Module (MSA) of Recommender of learning objects by competencies (RECoaComp)-MSA-RECoaComp. This is intended to recognize the socio -affective aspects in recommending Learning Objects (OAs) skills. The module is being implemented by a multidisciplinary team and is on the prototyping phase. In the first stag...

In this paper, a real-time facial expression recognition system is proposed to classify images of human facial expressions into a two dimensional model of emotion. The system is comprised of a facial feature detection system that uses constrained local models to locate the features, and a facial expression recognition system that utilizes multi-class support vector machines to classify the faci...

BACKGROUND Combining two standard-of-care medications for Alzheimer's disease (AD) into a single once-daily dosage unit may improve treatment adherence, facilitate drug administration, and reduce caregiver burden. A new fixed-dose combination (FDC) capsule containing 28 mg memantine extended release (ER) and 10 mg donepezil was evaluated for bioequivalence with co-administered commercially avai...

In this paper we use a result by J. Krasinkiewicz to present a description of the topological behavior of an open map defined between dendrites. It is shown that, for every such map f : X → Y, there exist n subcontinua X1, X2,. . ., Xn of X such that X = X1∪X2∪· · ·∪Xn, each set Xi∩Xj consists of at most one element which is a critical point of f , and each map f|Xi : Xi → Y is open, onto and c...

1. TALK SUMMARY I chose the title Metadata is back! because of schema.org, which is a joint effort of Bing, Google and Yahoo to provide a collection of schemas for marking up Web pages with machine-readable data. This helps search engines to understand the meaning of information and allows them to provide rich search results to the user, which makes it easier for them to find relevant informati...

This paper makes two contributions to increasing the engagement of users in virtual heritage environments by adding virtual living creatures. This work is carried out on the context of models of the Mayan cities of Palenque and Calakmul. Firstly, it proposes a virtual guide system. The guide navigates a virtual world and tells stories about the locations within it, bringing to them its personal...

nature of emotions. A second factor that contributes to the difficulty of improving accuracy is the abstract nature of emotions. To apply emotion assessment techniques for evaluating affective interfaces, we need to measure and quantify the abstract construct of emotion. Measuring emotions is then a quest to map the abstract world of emotions onto a mathematical, quantitative measure. Without a...
