Welcome to UMAP 2014

UMAP is the premier international conference for researchers and practitioners working on systems that adapt to their individual users, or to groups of users, and collect and represent information about users for this purpose. UMAP is the successor to the biennial User Mo- deling (UM) and Adaptive Hypermedia and Adaptive Web-based Systems (AH) conferences that were merged in 2009. It is organized under the auspices of User Modeling Inc. The conference spans a wide scope of topics related to user modeling, adaptation and personalization, considering: UMAP in the era of big data, social data, and pervasive computing; technological and socio-pedagogical underpinning of user modelling and user adaptive interaction; applications of adaptation and personalisation.

The 22nd Conference on User Modeling, Adaptation and Personalization will be held in Ho- tel Comwell Hvide Hus in Aalborg, North of Denmark. Aalborg is a multi-faceted city - full of contrasts. A city with a lust for life and all of its pleasures. It is also grand on a manageable scale. All the major city attractions are concentrated within easy distance. From fast-paced fun to peaceful oases. From a foaming draft beer to sublime gastronomy. From the Viking era to the Middle Ages, to modern art.

Thanks for coming and welcome to Aalborg and Denmark.

For the meteorologist Weather in Denmark varies with the seasons. Denmark has a temperate climate and can be humid and overcast. The winters are usually mild and windy, and the summers can be cool or sunny. The weather in Denmark is a popular subject for discussion as it often changes from day to day and even during the day. It is therefore a good idea to bring a coat or an umbrella on outdoor activities. To check the weather forecast when you visit Aalborg, please visit the website of the Danish Meteorological Institute www.dmi.dk for the latest forecast. View the forecast for the next 5 days here: http://www.dmi.dk/eng/index/ forecasts.htm For the Benjamin Franklin Electrical appliances run at 230 volts in Denmark. Electrical outlets in Denmark use a two- prong plug typical for continental Europe. Most laptops will automatically work with 220- 230 volts (check the back of your laptop for power input markings). For Cary Grant The conference is a non-smoking event and smoking is prohibited throughout the venue. However, for those who do not want to walk outside for smoking, there are a smokers’ lounge and a smokers’ terrace in the building. For the one who wears a seat belt Generally speaking, Denmark is a very safe country and Aalborg is a particularly safe city. Like in most major cities in the world, however, it is advisable to watch ones belongings and valuables while being in public places and to keep cars locked. Currency and Banks Denmark’s official currency is the Danish krone. The krone is issued through the National Bank of Denmark and is also used in the provinces of Greenland and the Faroe Islands. The currency is pegged at approximately 7.46 kroner per euro (€). There are numerous ATM with 24-hours service cash dispenser in the city. Major credit cards are widely accepted in the hotel, restaurant, taxi and stores. Time The time in Aalborg is Central European Time (Summer Time GMT+1)

Welcome Reception at Utzon Center Monday, 7th of July 2014 18:30 - 20:30

The City of Aalborg’s official opening reception will be held at Utzon Center. The Utzon Cen- ter functions as a venue for diffusion and innovation, where art, architecture and design interact with exhibition, education, conferences, meetings and culinary experiences - an apt tribute to the Danish architect Jørn Utzon (1918-2008). Jørn Utzon grew up in Aalborg. It is therefore obvious that this architecture, design and cultural centre should be placed in Aal- borg – in the same area at Honnørkajen where he use to walk by on his way to school every day. The Center is designed by Jørn Utzon himself in cooperation with his son Kim Utzon. Utzon Center has become a gathering point at the water front where there is an active life for students, for the locals as well as visitors from Denmark and foreign nations. A light selection of snacks and beverages will be served and you will have free access to enjoy the current exhibitions at Utzon Center that evening.

Technical Program

Monday July 7th 2014, Tutorial 1, 9:00 - 12:30 User Affect and Sentiment Modelling by Björn W. Schuller Room: room P1 Abstract: Affect and Sentiment Recognition have matured to the degree where they are ready for real-world application. At the same time, the interest in such technology has tremendously grown over the last decade, and expectancy is nothing short of a potential to drastically change our way we interact with technology. Affect and emotion are omni-present - be it if a system does not react in the way we want it to, or - in the better case - be- cause it does. In addition, users may be affected by other influences and hu- mans certainly take such cues into account when interacting. Accordingly, there is great interest in having future interactive systems do so as well to make communication with them feel more natural, sensitive, and "intelligent". Modelling of "affect" thereby comprises an increasingly broader range of mental states beyond the "big six" basic emotions. Today's approaches target increasingly more subtle affective states including also social emotions or mental states such as cognitive and physical load, intoxi- cation, pain, or sleepiness, just to name a few. Models to represent affect are various, and dimensi- onal modelling is increasingly more used rather than looking at a closed inventory of discrete la- bels. Sentiment can be considered as one of these dimensions, highly related to valence, but usually in connection with an object or target the sentiment is directed at. This tutorial introduces the principles, methods, and state-of-the-art in user affect and sentiment modelling focussing first on speech and text, but also including facial expression, body gestures, physiological sensors, interaction patterns and context. It further introduces typical databases, tools, and benchmarks in the field, and touches upon use-cases and examples of affect-aware systems and their engineering. Emphasis is thereby laid on modelling and recognition "in the wild" and independent of the user. In detail, it will guide through the following parts:  Motivation for User Affect and Sentiment Modelling, Classes, Dimensions and Other represen- tation forms, Affect and Sentiment Data & Benchmarks, Database creation, Monomodal, Mul- timodal databases, Benchmark tests and challenges, Affect and Sentiment Recognition, Moda- lities, Pre-processing and de-noising, Features and selection, Classification and regression, Au- tonomous learning and adaptation, Affective Output and Feedback, Affect synthesis, Feed- back generation, System integration aspects, Confidence measures, Context integration, Di- stributed processing, Encoding, Tools, Labelling Toolkits, Feature Extraction Toolkits, Learning Toolkits, Use-Cases, The (likely) "next big things" in the field

Presenter: Björn W. Schuller received his diploma in 1999, his doctoral degree for his study on Au- tomatic Speech and Emotion Recognition in 2006, and his habilitation in 2012 all in electrical engineering and information technology from TUM/Germany.

Friday July 11th 2014, Tutorial 3, 14:00 - 18:00 Title: Social Information Access Room: room P1 Abstract: The power of the modern Web, which is frequently called the Social Web or Web 2.0, is frequently traced to the power of users as contributors of various kinds of contents through Wikis, blogs, and resource sharing sites. However, the community power impacts not only the producti- on of Web content, but also the access to all kinds of Web content. A number of research groups worldwide explore what we call social information access techniques that help users get to the right information using “collective wisdom” distilled from actions of those who worked with this information earlier. Social information access can be formally defined as a stream of research that explores methods for organizing users' past interaction with an information system (known as explicit and implicit feedback), in order to provide better access to information to the future users of the system. It covers a range of rather different systems and technologies from social navigation to collaborative filtering. An important feature of all social information access systems is self-organization. Social information access systems are able to work with little or no involvement of human indexers, organizers, or other kinds of experts. They are truly powered by a community of users. Due to this feature, social information access technologies are frequently considered as an alternative to the traditional (content-oriented) technologies. The goal of this tutorial is to provide an overview of the emerging social information access research stream and to provide some practical guidelines for building social information access systems.

Presenter: Peter Brusilovsky is a Professor of Information Science and Intelli- gent Systems at the University of Pittsburgh, where he directs Personalized Adaptive Web Systems (PAWS) lab. Peter has been working in the field of adaptive educational systems, user modeling, and intelligent user interfaces for over 20 years.

He is also the current President of User Modeling Inc., a professional association of user modeling researchers.

th Friday July 11 2014, Tutorial 2, 9:00 - 12:30 Title: Personalization for behaviour change Room: room P1 Abstract: Digital behaviour intervention is a growing area of research which investigates how interactive systems can encourage and support people to change their behaviour, for their own or communal benefits. Personalization plays an important role in this, as the most effective persuasive and motivational strategies are likely to depend on user characteristics such as the user’s personality, affective state, existing attitudes, behaviours, knowledge, and goals. Example application areas include healthcare (e.g., encouraging people to eat more healthily and exercise more), education (e.g., motivating learners to study more), environment (e.g., encouraging people to use less energy and more public transport), and collaborative content development (e.g., incentivising people to annotate resources, participate online). This tutorial will cover the role of personalization in behaviour change technology, and methods and techniques to design personalized behaviour change technology. The tutorial will include both traditional and more recent approaches (such as gamification). It will be highly interactive, with short interactive lectures, exercises and mini- experiments. Presenters: Julita Vassileva is a professor of Computer Science at the University of Saskatchewan, Canada. Her research areas involve human issues in decentralized software environments: user modeling and personalization, and in designing incentive mechanisms for encouraging participation and facilitating trust in web, cloud and mobile applications. She is interested in how to use personalized recommendations, games and social influence to support people in their learning and engaging in beneficial behaviours. She serves on the Editorial Boards of User Model- ling and User Adapted Interaction, Computational Intelligence and IEEE Transactions on Learning Technologies. She has served on the PC of Persuasive since 2006. Judith Masthoff is an associate professor of Computing Science at the University of Aberdeen, UK.

Monday July 7th 2014, PIA 2014 9:00 - 18:00 The Joint Workshop on Personalized Information Access Room: Bøgesalen Description: This unique workshop was a result of merging two workshops with overlapping topics - the First Workshop on Personalized Multilingual Information Access (PMIA 2014), and the First Workshop on Personalizing Search - From Search Engines to Exploratory Search Systems (PESE 2014): • The PMIA 2014 workshop was designed to share, discuss, and combine ideas for novel solutions that support users according to their particular language abilities, as well as other characteristics (e.g. culture, domain expertise) and contexts (e.g. intent, topic) that influence what and how information should be retrieved, composed, and presented. • The PESE 2014 workshop was designed to explore another subtopic of personalized information access: addressing the challenges in user modeling when aiming to bring personalization to complex exploratory search tasks. During the reviewing process, the organizers discussed the overlapping nature of the workshops and a broader scope of interesting submissions, and decided that it would be most appropriate to merge these workshops under a broader topic of personalized information access. The organizers hope that the workshop results will directly influence the design of personalized applications that support more effective access to knowledge and deliver users search experiences which are tailored to their information needs and contexts.´

Schedule for The Joint Workshop on Personalized Information Access 09:15-09:30: Introduction 09:30-10:30: Keynote by Pia Borlund Evaluation of interactive information retrieval by use of simulated work task situations. The talk introduces the test instrument named a "simulated work task situation" that is commonly used in evaluations of interactive information retrieval (IIR). IIR evaluations focus on users’ satisfaction with retrieved information and use of IR systems. The test instrument takes the form of written search task descriptions that are assigned to the test participants. The objective of the use of simulated work task situations is to obtain reali- stic, reliable, and comparable search and assessment behaviour during testing. The talk presents the concept of simulated work task situation, and the requirements for the use of it as a test instrument. The talk further emphasises the importance tailoring of the simulated work task situations towards the group of test participants by providing illustrative examples of successfully tailored simulated work task situations and less successfully ones. 10:30-11:00: Coffee break 11:00-11:20: Supporting Exploratory Search Through User Modeling.

Friday July 11th 2014, PALE 2014 9:00 - 18:00 Workshop on Personalization Approaches in Learning Environments Room: Det Ny Kilden Description: The PALE 2014 workshop is a follow-up of the three previous editions of PALE. The focus of this workshop series is put on the different and complementary perspectives in which personalization can be addressed in learning environments. From the past experience we have identified new areas of interest in this research scope to complement the previous ones. In this workshop we would like to share and discuss the current research on how user modeling and as- sociated artificial intelligent techniques provide the personalization support in a wide rangeof learning environments, which are increasingly more sensitive to the learners and their context, such as: intelligent tutoring systems, learning management systems, personal learning environments, serious games, agent-based learning environments, and others. We are especially interested in the enhanced sensitivity towards learners’ interactions (e.g., sensor detection of affect in context) and technological deployment (including web, mobiles, tablets, tabletops), and how can this wide range of situations and features impact on modeling the learner interaction and context. Furthermore, we aim to cover the every time more demanding need of personalized learning in massive open online courses (MOOCs). Topics of interest:

 Affective computing, ambient intelligence

 Personalization of MOOCs

 Learner and context awareness

 Social and educational issues to be addressed

 Open-corpus educational systems, adaptive mobile learning

 Successful methods and techniques

 Reusability, interoperability, scalability

 Evaluation of adaptive learning environments Web: http://adenu.ia.uned.es/workshops/pale2014 Organizers:

Workshop on Personalization in eGovernment Services and Applications Room: Bøgesalen Description: The advent of e-government (e-Gov) initiatives has changed the interaction between governments and citizens. Services can now be delivered by means of virtual channels, e.g. through Web portals or mobile apps, or even online communities, and citizens can exploit these channels to interact with public administration. In this new scenario, innovative solutions based on e-Gov service offers, that are better tailored to citizens needs, can facilitate the access to services and reduce the red tape that usually cha- racterizes the public service provision. Even though several personalization methods and user modeling techniques have been proposed and successfully applied in several domains (e.g., e-commerce), the application of these approaches in the eGovernment domain is still in its infancy. As an example, while, in an e- commerce, we can quite easily catch user preferences and subsequently make suggestions according to the user profile, in the e-Gov domain the concept of preference itself is difficult to define. There are also potentially ethical (including privacy) issues related to the fact that citizens might be in a dependence relationship with governments, and automatic user profiling might be considered big brother and not desirab- le. The major goal of this workshop is to stimulate the attention of the scientific and business community on the aforementioned issues to move towards more user-aware and adaptive services in e-Gov by means of personalization methods. We are specifically interested in the role of user modeling and profiling in advanced public service design and delivery by dealing also with aspects related to privacy, security, and multilingualism. Following on the successful inaugural edition of the UMAP-PEGOV workshop of last year, this second workshop on Personalization in eGovernment Services and Applications aims to stimulate further interest of the scientific and business communities on the aforementioned issues to move towards more user-aware and adaptive services in the e-Gov domain by means of personalization methods. Topics of interest:

 Motivations, benefits, and issues of personalization in e-Gov, Approaches for the personalization of inclusive, personal and interactive e-Gov services, User and context awareness in personalization of e-Gov services ,Multilingual e-Gov services, Adaptation, personalization and recommendation models and goals in e-Gov, User, group and family modeling in e-Gov, Mining of user behavior, opinion mining, and sentiment analysis in e-Gov

Friday July 11th 2014, EMPIRE 2014 9:00 - 18:00 Workshop on Emotions and Personality in Personalized Services Room: Birkesalen Description: The 2nd workshop on Emotions and Personality in Personalized Services will be organized in conjunction with the UMAP 2014 conference and will be held in Aalborg, Denmark, as a full-day workshop on 11. July 2014. Personality and emotions shape our daily lives by having a strong influence on our preferences, decisions and behaviour in general. Hence, personalized systems that want to adapt to end users need to be aware of the user’s personality and/or emotions to perform well. Affective factors may include long-term personality traits or shorter-term states ranging from ‘affect dispositions’, ‘attitudes’ (liking, lov- ing, hating,…), ‘interpersonal stances’ (distant, cold, warm,…), ‘moods’ (cheerful, irritable, depressed,…) or ‘real emotions’. Recently, there have been extensive studies on the role of personality on user preferences, gaming styles and learning styles. Furthermore, some studies showed that it is possible to extract personality information about a user without annoying questionnaires, by analyzing the publicly available user’s social media feeds. Also, the affective computing community has developed sophisticated techniques that allow for accurate and unobtrusive emotion detection. Generally, emotions can be used in personalized systems in two ways: (i) either to change the emotion (or mood, e.g. from a negative to a positive) or (ii) to sustain the current emotion (e.g. keep a user “charged” while doing sports). Recent studies showed that such information can be used in various personalized systems like emotion-aware recommender systems. Topics of interest:  Adaptation strategies using affect and/or personality (e.g. to different learning styles, openness to diverse content etc.)  Scenarios/domains where emotions and personality could be utilized effectively  Privacy issues, Evaluation measures/strategies  Emotions as context, Emotions in the decision-making process for recommender systems, Role of personality on user similarities, Emotion detection in recommended content consumption, Emotion detection as non-invasive feedback, Affective tagging of multimedia content and services, Emotion- based evaluation metrics (satisfaction…)  Lifestyle recommender systems, Personality and mood for group decision making  Incorporating personality and emotions in user models  Datasets for affective modeling (collecting, available)  Personality traits acquisition (explicit and implicit), Personality and interfaces/control/bubble- control  Could interfaces/control/bubble-control be personalized based on personality traits  Personality and users’ tasks/goals  Social signal processing for personalized services, Strategies for modeling emotions and personality, Detecting triggers and causes of emotion  Theories about the relationship between reasoning and affect, between decision-making and affect, Methods for evaluating the utility of adaptation to affective factors  Personality-based preference elicitation Web: http://empire2014.wordpress.com/ Organizers:

Friday July 11th 2014, NRA 2014 14:00 - 18:00 Workshop on News Recommendation and Analytics Room: Bøgesalen Description: The news domain is characterized by a constant flow of unstructured, fragmentary, and unreliable news stories from numerous sources and different perspectives. Finding the right information, either in terms of individual news stories or aggregated knowledge from analyzing entire news streams, is a tremendous challenge that necessitates a wide range of technologies and a deep understanding of user preferences, news contents, and their relationships. This workshop addresses primarily news recommender systems and news analytics, with a particular focus on user profiling and techniques for dealing with and extracting knowledge from large-scale news streams. The news streams may originate in large media companies, but may also come from social sites, where user models are needed to decide how user-generated content is to be taken into account. This workshop aims to create an interdisciplinary community that addresses design issues in news recommender systems and news analytics, and promote fruitful collaboration opportunities between researchers, media companies and practitioners. Topics of interest:

 News semantics and ontologies, News summarization, classification and sentiment analysis

 Recommender systems and news personalization, Group recommendation for news

 User profiling and news context modeling

 News evolution and trends , Large-scale news mining and analytics

 Evaluation methods

 News from social media , Big Data technologies for news streams

Tuesday July 8th 2014, Keynote Speaker 1, 9:30 - 10:30 Title: The ABCS: A Framework for Thinking about People-Centered Systems Design Presenter: Elisabeth Churchill Room: Det Ny Kilden Chairman: Vania Dimitrova

Abstract: Interactive technologies pervade every aspect of modern life. Web sites, mobile devices, house- hold gadgets, automotive controls, aircraft flight decks; everywhere you look, people are interacting with technologies. This trend is set to continue as we move towards a world comprising Smart Cities built around the Internet of Things. Unfortunately, much of the rhetoric surrounding this dawning age of ubiquitous and embedded computing fails to appropriately consider the people at the centre of it. These people are embo- died social agents with motivations, emotions, capabilities, capacities, proclivities and predilections. Techno- logical imaginings around the Internet of Things are often steeped in generalities or idealised scenarios of use. Such imaginings typically forget that design is always about meeting particular peoples' needs in particular contexts. From concept to ideation to prototype and evaluation, the design of interactive technologies and systems that are intended for people should start with some understanding of who the users will be, what tasks and experiences they are aiming for, and what the circumstances, conditions or context(s) are at play. In this talk, I will discuss a simple people-centric framework devised with my colleagues and coauthors to inform the way we think about design, the ABCS of designing interactive systems. A descriptive guide rather than a prescriptive checklist, the framework draws on basic research in ergonomics, psychology and user modeling. It is intended to focus design thinking about people as the users of interactive, computational systems. It is intended to support us as the designers of interactive technologies as we scope, draft and iterate on the design space of imagined interactive experiences. Using examples from my own work, I will illustrate how this framework has been explicitly and/or tacitly applied in the design, development and evaluation of interactive, multimedia systems. In particular, I will consider how this framework is currently being applied to rethinking the concept of personalization.

Wednesday July 9th 2014, Keynote Speaker 2, 9:00 - 10:00 Title: Mobile Sensing and Understanding User Behavior in Urban Contexts Presenter: Kaj Gronbæk Room: Det Ny Kilden

Chairman: Peter Dolog

Abstract: In the EcoSense project we strive to understand human activity in urban contexts and how it impacts the local environment and the climate in general. We develop methods that combine mobile sensing, mobile experience sampling, and qualitative ethnographic methods to understand behavioral patterns, their impacts, and the potentials to change behavior where needed. The methods involve disse- mination of smartphone apps to the general public or specific user groups to sense and probe their activities in order to make analysis as well as to support the everyday life of the users. Examples of environmental domains for mobile sensing and analysis are transportation behavior, green transportation campaigns (e.g. promotion of biking and electric vehicles), pollution mapping, as well as sensing presence and energy related activities in large buildings. But the methods may also generalize beyond climate related behavior to e.g. safety mapping of city areas, and understanding participant behavior during large urban cultural events. The talk will give an overview of the methods being developed and examples of their usage. Finally I will discuss important challenges ranging from collection of data from a large number of heterogeneous devices, maintaining data collection, making sense of big data from mobile sensing,

Thursday July 10th 2014, Keynote Speaker 3, 9:00 - 10:00 Title: Computing and Autism: How a real problem drives computing research Presenter: Gregory D. Abowd Room: Det Ny Kilden

Chairman: Tsvi Kuflik

Abstract: In 2002, I had a fortunate collision of my personal and professional lives when I realized that work in ubiquitous computing, specifically the automated capture of live experiences for later access, could actually have an impact on the world of autism. I am the father of two boys with autism, and for the past decade I have seen many different ways that computing technology can address challenges fa- ced by a wide variety of stakeholder communities linked with autism, from the individuals and their fami- lies, to educators, therapists, clinicians and researchers. In this talk, I want to explain how a concrete applications domain, such as autism and related developmental disabilities, can present a wide variety of opportunities for computing research.
