ACM RecSys 2012 Workshop on Recommender Technologies for Lifestyle Change

RecSys 2012 Workshop
Recommender Technologies for Lifestyle Change

In conjunction with the 6th ACM Conference on Recommender Systems (RecSys’12) September 13, 2012, Dublin, Ireland


In today’s society, particularly in the affluent society, lifestyle is
influenced by technology and the abundance of financial resources.
Moreover, many believe that nowadays medical knowledge can be immediately
applicable in case of illness, and cure illnesses also caused by bad
habits, as technical knowledge can be used for repairing a broken car.

This results in lifestyles that do not care about the negative long-terms
effects on each individual person, but also on the environment. The most
prominent example of this is represented by various types of chronic
illnesses in developed countries that result from poor lifestyle choices
(e.g. diabetes or heart diseases).

In this context, the aim of this workshop is to explore possibilities for
recommender systems to support  users in taking useful decisions related
to various aspects of their lifestyle; we call them Lifestyle  Change
Recommender Systems (LSCRS).

There are three main challenges for LSCRSs: firstly, such systems have to
assess the user’s context for  delivering such recommendations. Secondly,
in order to promote any change in the lifestyle of the user,  they have
to recommend a tailored sequence of items, mostly actions, taking into
account the dependencies  between items and the effects of each item
recommendation. Thirdly, the systems have to be defined in a way that
favors the user’s continuous attention, and allows to explain the reasons
for the  change in the user’s future behavior, and to communicate the
changes already effectuated.

Hence, in order to provide an effective support to lifestyle change,
recommender systems need to provide communicative capabilities, e.g, with
multi-modal dialogue systems. Recommender technologies must initiate a
feedback-change-loop that could contribute to lowering the risks of severe
illnesses for many individual users and to improving  the overall
environmental situation.

In the light of these challenges, submissions are solicited that address
the following topics:

– Surveys of lifestyle related activities and technological approaches to
monitoring them
– Context modeling for activity recommendations
– Formal models of sensor data for monitoring every day activities
– User models for every day life recommendations that provide
user-tailored content
– Motivational models for lifestyle, every day activities, and
environmental responsibility
– Recommendations of sequences of items (e.g. physical exercises for a
whole week, planning meals for a month)
– Measures of the effectiveness for lifestyle change recommender systems
– Approaches to combine sensor data and interactive user input in LSCRSs
– Strategies to cement behavioral change
– Strategies for situation- and user-aware presentation of recommendations
– Persuasive technologies for interaction with and/or among users on their
personal situation,
their habits, and their options to change their lifestyle
– Recommendation of activities for leisure time and lifestyle
– Recommendation of information sources (e.g. forum entries, blogs) for

June 18, 2012: Workshop paper submission deadline
July 9, 2012: Author notification
July 23, 2012: Camera-ready workshop papers due
Sept 13, 2012: Workshop date

Submit either a full paper of no more than 6 pages, or a short paper (at
most 4 pages). Short papers may address an important problem for further
research or describe a practical problem or an interesting lesson learned.
In addition, we solicit proposals for short demonstrations (at most 4
pages, and software demonstrations taking at most 15 minutes), emphasizing
the original contribution, functionality or conceptual foundation of the

All submissions will be handled electronically in PDF format. The
submissions should follow the RecSys 2012 style guide (paper templates are
provided in Microsoft Word and LaTeX on the conference website: Papers should be submitted
via EasyChair submission system
( If you have
used EasyChair before, you may use your existing username and password.
Otherwise please create a new EasyChair account.

Each submission is blind reviewed by three members of the program
committee. Refereeing criteria are  relevance to workshop topics,
significance and novelty of the research, technical content, discussion on
relation to previous work and clarity of presentation.

At least one author of each accepted paper is required to attend the
workshop to present the paper.
