*** LAST CALL FOR PAPERS *** 27th ACM International Conference on User Modeling, Adaptation and Personalization (ACM UMAP 2019) "Making Personalization Transparent: Giving control back to the User" Golden Bay Beach Hotel 5*, Larnaca, Cyprus, June 9-12, 2019 http://www.cs.ucy.ac.cy/~george/lm/lm.php?tk=YWlyLUwJCQlhaXItTEBsaXN0c2Vydi5... Abstracts due: January 25, 2019 (mandatory) Papers due: February 1, 2019 BACKGROUND AND SCOPE ACM UMAP, "User Modeling, Adaptation and Personalization", is the premier international conference for researchers and practitioners working on systems that adapt to individual users, to groups of users, and that collect, represent, and model user information. ACM UMAP is sponsored by ACM SIGCHI and SIGWEB. The proceedings are published by ACM and will be part of the ACM Digital Library. ACM UMAP covers a wide variety of research areas where personalization and adaptation may be applied. This include (but is in no way limited to) a number of domains in which researchers are engendering significant innovations based on advances in user modeling and adaptation, recommender systems, adaptive educational systems, intelligent user interfaces, e-commerce, advertising, digital humanities, social networks, personalized health, entertainment, and many more. This year the conference hosts three new tracks, one on privacy and fairness, one on personalized music access, and one on personalized health. CONFIRMED INVITED SPEAKERS · Marios Avraamides, University of Cyprus · Judith Masthoff, Utrecht University · Mounia Lalmas-Roelleke, Spotify London CONFERENCE TRACKS Track 1 - Personalized Recommender Systems Chairs: Marko Tkalcic, Free University of Bozen-Bolzano, marko.tkalcic@unibz.it Alan Said, University of Skövde, alansaid@acm.org Personalized, computer-generated recommendations have become a pervasive feature of today's online world. The underlying recommender systems are designed to help users and providers in a number of ways.

From a user's viewpoint, for example, these systems assist consumers in finding relevant things within large item collections. On the other hand, from a provider's perspective, recommenders have also shown to be valuable tools to steer consumer behavior. From a technical perspective, the design of such systems requires the careful consideration of various aspects, including the choice of the user modeling approach, the underlying recommendation algorithm, and the user interface. This track aims to provide a forum for researchers and practitioners to discuss open challenges, latest solutions and novel research approaches in the field of recommender systems. Besides the above-mentioned technical aspects, works are also particularly welcome that address questions related to the user perception and the business value of recommender systems.

Topics include (but are not limited to): · Recommendation algorithms · Recommender and personalization system evaluation · User modeling and preference elicitation · Users' perception of recommender systems · Business value of recommendation systems and multi-stakeholder environments · Explanations and trust · Context-aware recommendation algorithms · Recommending to groups of users · Case studies of real-world implementations · Novel, Psychology-informed User- and Item-modeling Track 2 - Adaptive Hypermedia And The Semantic Web Chairs: Liliana Ardissono, University of Torino, liliana.ardissono@unito.it Katrien Verbert, KU Leuven, katrien.verbert@cs.kuleuven.be Adaptive hypermedia and adaptive web explore alternatives to the traditional "one-size-fits-all" approach in the development of web and hypermedia systems. Adaptive hypermedia and adaptive web systems build a model of the interests, preferences and knowledge of each individual user, and use this model in order to adapt the behavior of hypermedia and web systems to the needs of that user. Semantic web frequently serves as an infrastructure to enable adaptive and personalized Web systems. Semantic web technology targets the use of explicit semantics and metadata to help web systems perform the desired functionality: this implies the use of linked data from the web, the use of ontologies in models, or the use of metadata in user interfaces, as well as the use of ontologies for information integration. This track aims to provide a forum to researchers to discuss open research problems, solid solutions, latest challenges, novel applications and innovative research approaches in adaptive hypermedia and semantic web. Topics include (but are not limited to): · Web user profiles · Adaptive navigation support · Personalized search · Web content adaptation · Analytics of web user data · Adaptive web sites and portals · Adaptive books and textbooks · Social navigation and social search · Navigation support in continuous media and virtual environments · Usability engineering for adaptive hypermedia and web systems · Novel methodologies for evaluating adaptive hypermedia and web systems · Semantic Web technologies for web personalization · Ontology-based data access and integration/exchange on the adaptive web · Ontology engineering and ontology patterns for the adaptive web · Ontology-based user models · Semantic social network mining, analysis, representation, and management · Crowdsourcing semantics; methods, dynamics, and challenges · Semantic Web and Linked Data for adaptation Track 3 - Intelligent User Interfaces Chairs: Li Chen, Hong Kong Baptist University, lichen@comp.hkbu.edu.hk Jingtao Wang, Google, jingtaow@acm.org Intelligent User Interfaces aim to improve the interaction between computer systems and human users by means of Artificial Intelligence. The systems support and complement different types of abilities that are normally unavailable in the context of human-only cognition. Previous work has found that humans do not always make the best possible decisions when working together with computer systems. By designing and deploying improved forms of support for interactive collaboration between human decision makers and systems, we can enable decision making processes that better leverage the strengths of both collaborators. More generally this research track can be characterized by exploring how to make the interaction between computers and people smarter and more productive, which may leverage solutions from human-computer interaction, data mining, natural language processing, information visualization, and knowledge representation and reasoning. Topics include (but are not limited to): · Adaptive personal virtual assistants (e.g., interaction with robots) · Adapting natural interaction (e.g., natural language, speech, gesture) · Intelligent user interfaces based on sensor data (UIs for cars, fridges, etc.) · Multi-modal interfaces (speech, gestures, eye gaze, face, physiological info, etc.) · Intelligent wearable and mobile interfaces · Smart environments and tangible computing · Transparency and control of decision support systems (e.g., semi-autonomous systems) · Explainable intelligent user interfaces · Affective and aesthetic interfaces · Tailored persuasion and argumentation interfaces · Tailored decision support (e.g., over- and under-reliance in uncertain domains) · Adaptive information visualization · Scalability of intelligent user interfaces to access huge datasets · User-centric studies of interactions with intelligent user interfaces · Novel datasets and use cases for intelligent user interfaces · Evaluations of intelligent user interfaces Track 4 - Personalized Social Web Chairs: Ilaria Torre, University of Genova, ilaria.torre@unige.it Osnat Mokryn, omokryn@univ.haifa.ac.il The social web is continuously growing and social platforms are a fundamental part of our life. Mediated communication is becoming the primary form of communication for young people, and adults follow in increasing numbers. Online communication is increasingly enriched by the use of memes, pictures, audio and video, though language (textual and oral) remains a fundamental tool with which people interact, convey their opinions, construct and determine their social identity. Lifelogging data (e.g., health, fitness, food) is growing as well on the social web. This type of personal information source, gathered for private use through personal devices, is now often shared in online communities. These trends open new challenges for research: how to harness the power of collective intelligence and quantified self data in online social platforms to identify social identities, how to exploit continuous feedback threads, and how to improve the individual user experience on the social web. We invite original submissions addressing all aspects of personalization, user models building and personal experience in online social systems. Topics include (but are not limited to): · Personalization of the web experience in social systems · Adaptations based on personality, society, and culture · Personalization algorithms and protocols inspired by human societies · Social recommendation · Identifying social identities in social media · Social and crowd-generated data for adaptation · Personalized information retrieval · Exploiting quantified self data on the social web of things · Data-driven approaches for personalization · Modeling individuals, groups, and communities · Collective intelligence and experience mining · Pattern and behaviour discovery in social network analysis · Opinion mining for user modeling · Sentiment analysis · Topic modeling for online conversations and short texts · Privacy, perceived security, and trust in social systems · Ethical issues involved in studying the social web · User awareness and control · Evaluation methodologies for the social web Track 5 - Technology-Enhanced Adaptive Learning Chairs: Jesús G. Boticario, UNED, jgb@dia.uned.es Inge Molenaar, Radboud University, i.molenaar@pwo.ru.nl At large there is an on-going "fusion" between humans and technological systems. The ongoing integration of devices into our daily lives furthers the integration of technology in human learning. With technology increasingly gaining more data and intelligence, a new era of technology-enhanced adaptive learning is emerging. Consequently, the interactions between learners, teachers and technology are becoming increasingly complex. Learning is a positioned as a complex human process that involves cognitive, metacognitive, motivational, affective and psychomotor aspects which interact with the learning context. Smart technological solutions are increasingly able to identify and model the learner needs on these five aspects and accordingly provide personalized support that can improve the effectiveness, efficiency and satisfaction of learning experiences. Current research in artificial intelligence combined with data science and learning analytics bring new opportunities to recognize, and effectively support individual learners' needs and orchestrate collaborate and classroom learning with intelligent learning solutions, and augment teachers in blended learning situations. The aim of this track is to foreground the systematic complexity of human learning and use systematic analytic approaches to measure, diagnose and support human learning with technologies. This covers not only formal educational settings, but also lifelong learning requirements (including workplace training) as well as the acquisition of skills informal learning settings (e.g., in daily activities, serious games, sports, healthcare, wellbeing, etc.). To address the wide spectrum of modeling issues and challenges that can be raised, contributions from various research areas are welcome. Therefore, this track invites researchers, developers, and practitioners from various disciplines to present their innovative adaptive learning solutions, share acquired experience, and discuss the main modeling challenges for technology enhanced adaptive learning. Topics include (but are not limited to): · Domain, learner, teacher and context modeling · Modeling cognitive, metacognitive, motivational, affective and psychomotor aspects of learning · Diagnosis of learner needs and calibration of support and feedback Adaptive and personalized support for learning · Dealing with ethical issues involved in detecting and modeling a wider range of information sources (e.g., information from novel sensing devices, ambient intelligent features) that may affect learning · Management of large, open, and public datasets for educational data mining · Agent-based learning environments and virtual pedagogical agents · Open corpus personalized learning · Collaborative and group learning · Adaptive technologies to orchestrated classroom Learning · Personalized teachers awareness and support tools · Multimodal learning analytics to personalize learning · UMAP aspects in specific learning solutions: educational recommender systems, intelligent tutoring systems, serious games, personal learning environments, MOOCs · Wearable technologies and augmented reality in adaptive personalized learning · Processing collected data for UMAP: educational data mining, learning analytics, big data, deep learning. · Semantic web and ontologies for e-learning · Interoperability, portability, and scalability issues · Case studies in real-world educational settings · New methodologies to develop user-centered highly personalized learning solutions Track 6 - Privacy And Fairness Chairs: Bart Knijnenburg, Clemson University, bartk@clemson.edu Esma Aimeur, University of Montreal, aimeur@iro.umontreal.ca Adaptive systems researchers and developers have a social responsibility to care about their users. This involves building, maintaining, evaluating, and studying adaptive systems that are fair, transparent, and protect users' privacy. We invite papers that study, in the context of UMAP, the topics of privacy (as well as innovative means to resolve privacy problems through algorithms, interfaces, or other technical or non-technical means), fairness (covering the spectrum from algorithmic fairness to social implications of adaptive systems), and transparency (as a concept of system usability as well as a means to resolve problems with privacy and fairness). Beyond this we encourage authors to submit to this track any work that ascribes to or advances the general idea of "adaptive systems that care".

These systems record information on user behavior in terms of actions on music items, such as play, skip, or playlist creation and modification. As a result, an abundance of user and usage data has been collected and is available to companies and academics, allowing for user profiling and to create and improve personalized music access. This track addresses unsolved challenges in this area relating to user understanding and modeling, personalization in recommendation and retrieval systems, modeling usage context, and adapting interactive intelligent music interfaces. This track aims to provide a forum for researchers and practitioners for the latest research on? user modeling and personalization for finding, making, and interacting with music. Topics include (but are not limited to): · Personalized music preference elicitation and preference learning · Psychological modeling of music listeners (e.g., personality, emotion, etc.) · Subjective perceptions of music (e.g., similarity, mood, tempo) social and cultural aspects of listening behavior (e.g., for group recommenders) · Applications for personalized music consumption and creation · Personalized playlist generation and continuation (e.g., sequences and transitions) · Personalized music interaction and interface paradigms (e.g., visualization, VR) · Explainability, transparency, and fairness in personalized music · Systems user-centric performance measures (e.g., diversity, novelty, serendipity, etc.) · Datasets (including benchmarks) for personalizing music retrieval and recommendation Track 8 - Personalized Health Chairs: Christoph Trattner, University of Bergen, trattner.christoph@gmail.com David Elsweiler, University of Regensburg, david@elsweiler.co.uk Growing health issues and rising treatment costs mean that technological systems are increasingly important for global health. Personalised systems, tailored to the needs and behaviours of individual patients, are one of the promising approaches to health promotion by encouraging lifestyle change, managing treatment programmes and providing doctors and other healthcare providers with detailed individualized feedback. The challenges to developing such systems, which model user needs and preferences, as well as appropriate medical knowledge to provide assistance and recommendations are plentiful. The diverse technologies which could potentially feature in solutions are equally vast, ranging from AI systems to sensors, from mobile computing, augmented reality and visualization, to mining the web or other data streams to learn about health issues and user behaviour. In this track we invite scholars working in these or related areas to contribute to the discourse on how technology can promote health. This track aims to provide a forum to researchers to discuss open research problems, solid solutions, latest challenges, novel applications and innovative research approaches and in doing so to strengthen the community of researchers working on Personalized Health and attract representatives from from diverse scholarly backgrounds ranging from computer and information science to public health, epidemiology, psychology, medicine, nutrition and fitness. Topics include (but are not limited to): · Algorithms and Recommendation Strategies to increase health · Mobile health · Quantified self · Applied data analytics and modeling for health · Health risk modeling and forecasting · Systems for Preventative Measures · Medical Evaluation Techniques · Domain Knowledge Representation · Behavioral Interventions: Persuasion/Nudging/Behavioral Change · HCI, Interfaces and Visualisations for health · Regulations and Standards · Human/ Expert-in-the-Loop · Gamification and Serious Games · Privacy, Trust, Ethics · Datasets SUBMISSION AND REVIEW PROCESS Papers should be submitted through EasyChair: http://www.cs.ucy.ac.cy/~george/lm/lm.php?tk=YWlyLUwJCQlhaXItTEBsaXN0c2Vydi5... The ACM User Modeling, Adaptation, and Personalization (ACM UMAP) 2019 Conference will include high quality peer-reviewed papers related to the above key areas. Maintaining the high quality and impact of the ACM UMAP series, each paper will have three reviews by program committee members and a meta-review presenting the reviewers' consensual view; the review process will be coordinated by the program chairs in collaboration with the corresponding area chairs. Long (8 pages + references) and Short (4 pages + references) papers in ACM style, peer reviewed, original, and principled research papers addressing both the theory and practice of UMAP and papers showcasing innovative use of UMAP and exploring the benefits and challenges of applying UMAP technology in real-life applications and contexts are welcome. Long papers should present original reports of substantive new research techniques, findings, and applications of UMAP. They should place the work within the field and clearly indicate innovative aspects. Research procedures and technical methods should be presented in sufficient detail to ensure scrutiny and reproducibility. Results should be clearly communicated and implications of the contributions/findings for UMAP and beyond should be explicitly discussed. Short papers should present original and highly promising research or applications. Merit will be assessed in terms of originality and importance rather than maturity, extensive technical validation, and user studies. For both long papers and short paper submissions, it is not required to anonymize the manuscripts, i.e., ACM UMAP will apply a single-blind reviewing process. Separation of long and short papers will be strictly enforced so papers will not compete across categories, but only within each category. Papers that receive high scores and are considered promising by reviewers, but didn't make the acceptance cut, will be directed to the poster session of the conference and will be invited to be resubmitted as posters. Papers must be formatted using the ACM SIG Standard (SIGCONF) proceedings template: http://www.cs.ucy.ac.cy/~george/lm/lm.php?tk=YWlyLUwJCQlhaXItTEBsaXN0c2Vydi5... . Please note that ACM changed its templates at the start of 2017, so please ensure that you use the new template and do not reuse an old template. All accepted papers will be published by ACM and will be available via the ACM Digital Library. At least one author of each accepted paper must register for the conference and present the paper there. AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of your conference. The official publication date affects the deadline for any patent filings related to published work. (For those rare conferences whose proceedings are published in the ACM Digital Library after the conference is over, the official publication date remains the first day of the conference.)
