It is our great pleasure to welcome you to the UMAP 2017 LBR, Demo, and TOR Track, the 25th User Modelling, Adaptation and Personalization, held in Bratislava, Slovakia organized between the July 9-12th, 2017. This track of UMAP wraps three categories: (i) Demos, which showcase research prototypes and commercially available products of UMAP-based systems, (ii) Late-breaking Results, which contain original and unpublished accounts of innovative research ideas, preliminary results, industry showcases, and system prototypes, addressing both the theory and practice of UMAP and (iii) Theory, Opinion and Reflection (TOR). TOR is an additional category introduced in this edition of UMAP. Papers in this category critically look at ongoing research topics, reflect on persistent or fleeting trends in the field and offer blue sky future agendas for UMAP research. A novelty related to the TOR category is the presentation format. TOR papers will be presented in the form of an interactive campfire session in a discussion corner during the poster session. In total, we received 13 LBR, 6 TOR, and 4 Demo submissions out of which 8, 3 and 3 were deemed of high quality by the reviewers. Further 6 LBR papers were accepted from the main conference.

It is our great pleasure to welcome you to the UMAP 2017 EvalUMAP workshop. The purpose of this workshop series is to establish comparative evaluation tasks and a suitable framework to support researchers in the user modelling and personalisation research field in comparing their research to that of others. In 2016 we discussed the key challenges in performing such comparative evaluations. This year we focus on the challenges of identifying appropriate datasets and methods. In particular, the planned outcomes of the workshop this year are as follows: (1) Understand the challenges and requirements related to the design of a shared task approach in User Modeling, Adaptation and Personalization space, (2) identify suitable and publicly accessible datasets that overcome the previous identified challenges and requirements and (3) using the identified datasets start designing shared evaluation tasks that will be performed throughout 2017 and be presented at UMAP 2018.

Research has shown that persuasive technologies are more effective when they are personalized. Persuasive strategies work differently for various people; hence a one size fits all approach may not bring about the desired change in behavior or attitude. This paper contributes to personalization in question and answer (Q&A) social networks by exploring the possibility of personalizing social influence strategies based on the computer programming skill level and the highest level of education of users. In particular, this paper explores the susceptibility of users in Stack Overflow, a Q&A social network, to social support influence strategies for novice and expert computer programmers. In addition, we explore if first degree holders respond to the social support influence strategies the same way graduate degree holders do. Using a sample size of 282 Stack Overflow users, we constructed four models using Partial Least Squares Structural Equation Modelling (PLS-SEM) and carried out multi-group analysis between these models. The results of our analysis show that social facilitation significantly influences cooperation for novice programmers, but not for expert programmers. In addition, social learning does not significantly influence the persuasiveness of the system for expert programmers compared to users who are novice in computer programming. For the users grouped according to their highest level of education, social learning influenced cooperation among the graduate degree holders and competition influenced the graduate degree holders to continue using the system. The result of this study can provide useful guidelines to social network developers that can be used in implementing personalized influence strategies in Q&A social communities.

During the phases of course construction, in Learning Management Systems, a teacher can be valuably helped by system's recommendations about learning objects to include in the course. A usual protocol is in that the teacher performs a query, looking for suitable learning material, and the system proposes a list of learning objects, with information shown for each one; then the teacher is supposed to make her choice, basing on the displayed information. Here we present a Recommender System for Learning Objects retrieved from Learning Objects Repositories, that is based on a ``social teacher model", based on the similarities with the teacher in the system, and the potential model evolutions over time. The proposed system is available as a Moodle plug-in. In the paper we show the details of the information decorating the learning objects retrieved after a query, the definition of the teacher model, and the similarity measure underlying the recommendation strategy.

Personalizing interactive systems including games increases their effectiveness. This paper explores and compares two main approaches to personalization: system-controlled and user-controlled adaptation. The results of large-scale exploratory studies of 1768 users show that both techniques to personalizing systems share seven common strengths of increasing users' perception of a system's relevance, usefulness, interactivity, ease of use, credibility and trust, and also increases users' self-efficacy. The results also reveal some unique strengths and weaknesses peculiar to each of the approaches that designers should take into consideration when deciding on a suitable adaptation technique to use in personalizing their systems. Users prefer system- over user-controlled adaptation.

Evaluation of personalized systems is a complicated endeavor. First, evaluation goals, methods and criteria are manifold and have to be carefully selected to fit the actual application scenario and the scope of the evaluated system. Second, it is considerably harder to locate the source of problems, compared to non-adaptive systems where problems most often reside on the UI level. Thus, in the past, a layered evaluation approach for personalized systems has been proposed that distinguishes between five layers that can theoretically all be the source of problems (e.g., collection of input data or adaptation decision). This paper outlines a use case related to personalized interaction comprising i) modeling a user's interaction abilities, ii) recommending interaction methods and devices that fit the user's individual needs, and iii) personalized system behavior and reaction to user input. Next, the paper describes experiences with an evaluation process using the layered evaluation framework.

Welcome to the 4th International Workshop on Educational Recommender Systems (EdRecSys) held in conjunction with the 25th ACM Conference on User Modeling, Adaptation, and Personalization (UMAP 2017). Recommender systems have become increasingly popular in recent years, helping us to make decisions about what products to buy, what movies to watch, what books to read or who to date. While these systems have shown their effectiveness in e-commerce, music and social networks, the field of education is an emerging and very promising application area. The educational environment is no longer limited to face-to-face classes; it includes online learning and activities using Technology Enhanced Learning (TEL), Learning Management Systems (LMS) and Massive Open Online Courses (MOOC), all of which can benefit from the application of recommender systems to alleviate information overload and improve personalisation, to better meet the needs of the individual student. For example, high school and university students can be provided with recommendations about: (i) suitable degrees and courses, based on their background, preferences and prior experience; (ii) project and thesis topics, and appropriate supervisors; (iii) internships and jobs; (iv) other students to work with (to do group work or peer learning); (v) suitable learning resources based on their knowledge, skills and learning style, e.g. books, tutorials, activities, etc. This workshop has brought together researchers and practitioners from the areas of user modeling and personalisation, recommender systems, education, data mining, learning analytics, intelligent tutoring systems and other related disciplines, to explore the use of recommender systems in education, share their experience and discuss the challenges and open research topics in the design and deployment of effective solutions.

It is our great pleasure to welcome you to the UMAP 2017 Workshop on Surprise, Opposition, and Obstruction in Adaptive and Personalized Systems (SOAP). Following the successful first edition of the workshop at UMAP 2016, we are happy to see a continuing and increasing interest in the workshop's topics. As with the first edition, for the second edition we were able to accept four highly relevant submissions, allowing us to discuss the challenges of recommending unexpected, nonetheless relevant and impactful artifacts during a focused half-day workshop. With the workshop being originally motivated by interviews with music creators and producers who articulated a strong rejection of "more-of-the-same" search engines and recommender systems as they challenge their notion of originality and, ultimately, pose a threat to their artistic identity, we realized that a demand for adaptive and personalized systems that not only have the capability to surprise, but also to oppose and even obstruct can be found in a wider field. In fact, this coincides with ongoing trends to deal with and escape generally negatively connoted effects of automatic recommender systems, such as the so-called "filter-bubble". Apart from the potential dangers of such effects on the unreflecting user, there seems to be a growing impression that collaborative, as well as content-based recommender systems keep making obvious, uninspiring, and therefore disengaging suggestions based on previous interactions. Over the last years, this has emphasized the value of system qualities beyond pure accuracy, e.g., diversity, novelty, serendipity, or unexpectedness, to keep the user satisfied. In fact, these approaches to kicking the user out of his or her "comfort zone" seem to be highly promising methods to increase satisfaction with a system in the long run.

Research has shown that Competition is a powerful intrinsic motivator of behavior change. However, little is known about the predictors of its persuasiveness and the moderating effect of culture. In this paper, we investigate the predictors of "the persuasiveness of Competition" (i.e. Competition) using three social influence con-structs: Reward, Social Comparison and Social Learning. Using a sample of 287 participants, comprising 213 individualists and 74 collectivists, we explored the interrelationships among the four social influence constructs and how the two cultures differ and/or are similar. Our global model, which accounts for 46% of the variation in Competition, reveals that Reward has the strongest influence on Competition, followed by Social Comparison. However, the model shows that Social Learning has no significant influence on Competition. Finally, our multigroup analysis reveals that, for our population sample, culture does not moderate the interrelationships among the four constructs. Our findings suggest that designers of gamified applications can employ Reward, Social Comparison and Competition as co-persuasive strategies to motivate behavior change for both cultures, as the susceptibilities of users to Reward and Social Comparison are predictors of their susceptibility to Competition.
