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.
