Objectives & Topics:
Information systems are becoming more and more intertwined with systems and
approaches developed with the purpose of keeping us healthy and increasing
our general wellbeing. In the two previous workshops on Health Recommender
Systems (HRS), we elaborated a great variety of fields in which recommender
systems can improve our awareness, understanding and behavior regarding our
own, and the general public's health. At the same time, these application
areas bring new challenges into the recommender community. Recommendations
that influence the health status of a patient need to be liable, today,
they often involve a human in the loop to make sure the recommendations are
sound. To make the recommender liable, complex domain-specific user models
need to be created, which creates privacy issues. While trust in a
recommendation needs to be explicitly earned by e.g. transparency,
explanations and empowerment, other systems might want to persuade users
into beneficial actions that would not be willingly chosen otherwise. The
variety of those challenges also results from the number and diversity of
stakeholders involved in health systems. Taking the patient's perspective,
simple interaction and safety against harmful recommendations might be the
prioritized concern. For clinicians and experts, on the other hand, what
matters is precise and accurate content. Finally, health care providers,
insurance providers, and clinics are interested in other aspects, e.g.
success rates, study results, and financial benefits of the new systems.
This workshop goes deeper into the discussions started at the two prior
workshops and works towards the further development of the research topics
in Health Recommender Systems.

Our aim is to enhance the results of the last two workshops in the
following areas:

** Elaborate discussion topics of the previous workshops on health
promotion, health care as well as methods
** Strengthen the community of researchers working on Health in RecSys
** Attract representatives from e.g. health, psychology, medicine,
nutrition, fitness
** Find cross-domain collaboration projects and funding targets
** Exchange and share infrastructure (datasets and tools)

We invite submissions that may include the following topics but are not
limited to:

** Algorithms and Recommendation Strategies
** Domain Knowledge Representation
** Regulations and Standards
** Medical Evaluation Techniques
** User Profiling
** Pervasive Systems
** Personalization
** Behavioral Interventions
** Persuasion/Nudging/Behavioral Change
** Gamification and Serious Games
** Adherence
** Empowerment
** Trust
** Explanations
** Patient Needs/ Satisfaction
** User Interaction Design
** Human/ Expert-in-the-Loop
** Privacy

The goal of this workshop is to share and discuss research and projects
that reach beyond classic recommender techniques and discuss health domain
related challenges of recommender systems.

We solicit research papers (up to 6 pages) and short position papers (2
pages), both in the ACM conference paper style. Participants can decide
between a research focused submission, resulting in a workshop
presentation, and a project focused submission, resulting in a workshop
poster. A selection of best papers will be presented in a flash talk.
Further papers will be presented in the form of a poster. Papers should be
submitted in EasyChair:

** Submission category research: innovative research ideas, preliminary
results or system prototypes

** Submission category project: funded research projects, industry and
research collaborations or health-care and research collaborations

Submission guidelines:
All submitted papers must:

** Be written in English;
** Contain author names, affiliations, and email addresses;
** Be formatted according to the ACM SIG Proceedings Template with a font
size no smaller than 9pt;
** Be in PDF (make sure that the PDF can be viewed on any platform), and
formatted for US Letter size;

Link or demo in attachment are preferred in both cases. All papers will be
peer-reviewed, must not be under review in any other conference, workshop
or journal (at the time of submission), and must contain novel
contributions. Accepted papers will be published according to the ACM
RECSYS 2018 WS publication rules.
Please use the workshop's EasyChair submission page for submitting your

A Few Remarks
**  The title of the paper, authors, and the author order cannot be changed
after the acceptance
** Major changes to the text of the reviewed and accepted papers are not
permitted after the review
** At least one of the authors should participate in the workshop, register
in the RecSys conference, and personally present the paper in the workshop.

RecSys 2018 will be hosted in Vancouver, Canada, at Parq Vancouver from
October 2-7, 2018. Please visit the RecSys 2018 website for more
