General Information:
Following the successful 2011 Workshop on Context-awareness in Retrieval and Recommendation we are delighted to invite you to the second installment which will be held in conjunction with the 2012 Conference on Intelligent User Interfaces.

Context-aware information is widely available in various ways such as interaction patterns, location, devices, annotations, query suggestions and user profiles and is becoming more and more important for enhancing retrieval performance and recommendation results. At the moment, the main issue to cope with is not only recommending or retrieving the most relevant items and content, but defining them ad-hoc. Further relevant issues are personalizing and adapting the information and the way it is displayed to the user’s current situation (device, location) and interests.

In this workshop we focus on the integration of context for retrieval and recommendation. We recognize a general content context and a user-centric content context. A general content context is a common case defined by time, weather, location and many similar other aspects. A user-centric content context is given by the content of user profiles such as language, interests, devices used for interaction, etc.

Important Dates:
* Paper submission [EXTENDED]: January 6th, 2012
* Notification: January 20th, 2012
* Camera-ready submission: January 27th, 2012
* Workshop: February 14th, 2012

Call for Papers:
The aim of the CaRR Workshop is to invite the community to a discussion in which we will try to find new creative ways to handle context-awareness. Furthermore, the workshop aims at improving the exchange of ideas between different communities involved in research concerning, among other HCI, machine learning, information retrieval and recommendation.
The workshop is especially intended for researchers working on multidisciplinary tasks who want to discuss problems and synergies.

The participants are encouraged to address the following questions:
* Which benefits come from context-aware retrieval and recommendation systems?
* How do user interfaces handle context?
* In what ways can context improve HCI?
* How can we combine general- and user-centric context-aware technologies?
* How should context affect the way information is presented?
* Which new means for collecting user feedback does UbiComp provide?
* What new type of items (beyond books, news and movies) are worth recommending by means of context-aware systems (e.g. places, friends, apps)?

The topics of interest include, but are not limited to, the following aspects:
* Context-aware information retrieval
* Context-aware profiling, clustering and collaborative filtering
* Machine learning for context-aware information retrieval and ontology learning
* Ubiquitous and context-aware computing
* Use of context-aware technologies in UI/HCI
* Context-aware advertising
* Recommendations for mobile users
* Context-awareness in portable devices

Paper submissions and reviews will be handled electronically through the CaRR page in EasyChair (which will be made available at a later point in time).
