CALL FOR PAPERS
---
RecSys'12 Workshop on Human Decision Making in Recommender Systems
In conjunction with the 6th ACM Conference on Recommender Systems
(RecSys’12)
September 9-13, 2012, Dublin, Ireland
Workshop website: http://recex.ist.tugraz.at/RecSysWorkshop2012
Submission deadline: June 15th, 2012
DESCRIPTION:
Interacting with a recommender system means to take different decisions
such as selecting a song/movie from a recommendation list, selecting
specific feature values (e.g., camera’s size, zoom) as criteria,
selecting feedback features to be critiqued in a critiquing based
recommendation session, or selecting a repair proposal for inconsistent
user preferences when interacting with a knowledge-based recommender. In
all these scenarios, users have to solve a decision task.
The complexity of decision tasks, limited cognitive resources of users,
and the tendency to keep the overall decision effort as low as possible
lead to the phenomenon of bounded rationality, i.e., users exploit
decision heuristics rather than trying to take an optimal decision.
Furthermore, preferences of users will likely change throughout a
recommendation session, i.e., preferences are constructed in a specific
decision environment and users do not know their preferences beforehand.
Decision making under bounded rationality is a door opener for different
types of non-conscious influences on the decision behavior of a user.
Theories from decision psychology and cognitive psychology are trying to
explain these influences, for example, decoy effects and defaults can
trigger significant shifts in item selection probabilities; in group
decision scenarios, the visibility of the preferences of other group
members can have a significant impact on the final group decision.
The major goal of this workshop is to establish a platform for industry
and academia to present and discuss new ideas and research results that
are related to the topic of human decision making in recommender systems.
TOPICS:
I) Theories, algorithms and applications
- Decision theories in recommender systems (e.g., priming, framing, and
decoy effects)
- Trust inspiring recommendation (e.g., explanation-aware recommendation)
- Persuasive recommendation (e.g., argumentation-aware recommendation)
- The role of emotions in recommender systems (e.g., emotion-ware
recommendation)
- Mechanisms for effective group decision making (e.g., group
recommendation heuristics)
- Detection and avoidance of decision biases (e.g., in item presentations)
- Sequential decision making and selection
- Applications of the above mentioned features
II) User modeling and preference elicitation
- Modeling user information search and decision making processes in
recommender systems
- Preference elicitation (e.g., eye tracking for automated preference
detection)
- Adaptive recommendation processes
- Active approaches to preference elicitation
III) User interfaces
- User interfaces for decision making (e.g., decision strategies and
user ratings)
- User interfaces for group decision making (e.g., group decision making
in e-tourism)
- Explanations in Recommender Systems
IV) Evaluation
- User perceptions leading to the acceptance of recommendations
- The role of diversity and serendipity for the acceptance of
recommendations
- Cultural differences (e.g., culture-aware recommendation)
- Empirical studies and innovative metrics of system performance
SUBMISSION INFORMATION:
Submit either a full paper of no more than 8 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 system. 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: http://recsys.acm.org/2012/call_for_papers.html).
Papers should be submitted via EasyChair submission system
(http://www.easychair.org/conferences/?conf=decisionsrecsys12). If you
have used EasyChair before, you may use your existing username and
password. Otherwise please create a new EasyChair account.
Each submission is refereed by at least two 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. A contribution
submitted as a long paper may be accepted as a short paper, if the
program committee considers it to be inadequate for a long paper but to
present an important issue. At least one author of each accepted paper
is required to attend the workshop to present the paper.
