1st International ‘Alan Turing’ Conference on Decision Support and Recommender Systems (DSRS-Turing 2019)

Objectives

Decision Making processes constantly occur in our daily lives, both at an individual, collective and large-scale societal level. Even for machines and AI systems, making autonomous and rational decisions has nowadays become part of their core duties. Decision making often occurs amid highly dynamic, uncertain and data-pervaded scenarios, thereby becoming increasingly complex. This conference based in the UK’s Alan Turing Institute brings together international researchers, industry professionals and domain experts to discuss latest trends and ongoing challenges in:

The event particularly aims at exploring the existing – or potential – interaction between various AI techniques and applications, and state-of-the-art decision support and recommendation approaches. Young researchers (PhD students, postdocs) are particularly encouraged to attend for an opportunity to network with – and receive advice from – leading experts in the field.


Topics of Interest

Students, researchers and professionals with interest or expertise in the following topics are encouraged to attend:

Submission

Young researchers are invited to submit extended abstracts in English.

  • Any submissions within the scope of the Topics of Interest list are welcome.
  • There are no particular constraints regarding format and length of extended abstracts, but we recommend a maximum of 4 pages in single column formatting.
  • The submission of the extended abstracts is exclusively for young researchers: PhD students, postdocs or academics who received their PhD on or after 2014.
  • Authors of accepted abstracts will be invited to showcase a poster – and optionally to present a demo – of their work, to network with and receive feedback from senior experts and attendees in general. Some selected authors will be also invited to deliver an 8-minute Flash Talk at a conference session.
  • The submission and acceptance of an extended abstract are not compulsory to attend.
  • After evaluation, notification of acceptance will be provided to authors via email. Please note that the full submissions will not be published, but plans are underway to ellaborate a mini-proceedings booklet with short abstracts of accepted works.

    Title: Personalising the Listening Experience

    Abstract: When users interact with the recommendations served to them, they leave behind fine-grained traces of interaction patterns, which can be leveraged to predict how satisfying their experience was. This talk will present various works and personal thoughts on how to measure user engagement. It will discuss the definition and development of metrics of user satisfaction that can be used as proxy of user engagement, and will include cases of good and bad scenarios. An important message will be to show that, when aiming to personalise the recommendations, it is important to consider the heterogeneity of both user and content to formalise the notion of satisfaction, and in turn design the appropriate satisfaction metrics to capture these. One way to do this is to consider the following angles when developing machine learning solutions for personalization: (1) Understanding intents; (2) Optimizing for the right metric; (3) Acting on segmentation; and (4) Thinking about diversity.

    Dr Christoph Trattner. University of Bergen (Norway)

    Title: Computational Analytics on the Web for Better Food Decision Making

    Abstract: According to the World Health Organization around 80% of cases of heart disease, strokes and type 2 diabetes could be avoided if people were to implement a healthier diet. Computational data analytics approaches have been touted as a valuable asset in achieving the ambitious goal of understanding user behavior and being able to develop intelligent online systems, which can positively influence people’s food choices. In this talk, I will present our latest research on computational data analytics approaches to understand, predict and potentially change food decision making in an online context. First, I will show to what extent online food interactions can be linked to real-world health issues such as obesity on a large-scale. After that, I will show how people upload, bookmark or rate online recipes in large online food communities and how contextual factors and biases such as seasonality, temporality, social context or presentation of recipes have an impact on popularity and how they are perceived. Furthermore, I will reveal to what extent these factors and biases can be exploited to model and predict the users’ online food choices. To conclude, I will present some preliminary work aiming to nudge people towards food choices and recent work on learning to recommend similar items from human judgments in that domain employing crowdsourcing.

    Speaker Bio: Christoph Trattner is an Associate Professor at the University of Bergen in the Information Science & Media Studies Department. Previously, he was an Asst. Prof. at MODUL University Vienna in the New Media Technology Department.

    Title: Recommender Systems and Decision-making in the Tourism Domain (tentative)

    Abstract: Recommender systems face specific challenges in the travel domain, as the tourism product is typically very complex. In addition, travelling can be seen as an emotional experience. Particularly in the early phases of a travel decision process, users are not able to explicitly express their preferences. Therefore, comprehensive user models are required. In this talk, I present a picture-based approach as an effective and joyful method to implicitly elicit user preferences for tourism products. In this approach, a user’s travel profile is composed of seven basic factors. The scores of these factors are determined by asking the user to select a number of pictures that are appealing to him or her. In addition, I will discuss automated ways for determining the seven-factor scores of tourism products to enable matchmaking for recommender systems. Finally, since travelling is typically a social activity, I will talk about group decision making and show that in order to understand the outcome of a group decision making process new strategies that go beyond the simple aggregation of the initial preferences of the group members have to be applied.
