Aim of the CaRR Workshop
Invite the community to a discussion in
which we will try to find new creative
ways to handle context-awareness
Improve the exchange of ideas between
different communities involved
(user interfaces, machine learning,
information retrieval and recommendation)

Previous Workshops
Context-awareness in Retrieval and Recommendation
Current SOA systems are generally context-ignorant,
CAMRa focused on identifying and utilizing contextual
data in real-life data from Moviepilot and Filmtipset.
Challenge on Context-aware Movie
Recommendation (CAMRa2010)
joint event with the Workshop on Context-aware
Recommender Systems (CARS-2010)
in conjunction with the ACM Recommender Systems
2010 Conference (RecSys2010).

Can We Define Context?
”Any information that can be used
to characterise the situation of
entities”, Dey 2001
1. Item context
•
•
Seasonal (Christmas, Oscar’s)
Relation (movie sequel, director, actor)
2. User context
•
•
•
•
13.02.2011
Surroundings (weather, location)
Company (alone, with friends)
Mood/emotions
any user related factor

Why do we need Context?
+
•
•
•
Filters relevant information
Ad hoc recommendations
Aware of changes
•
•
What is context?
Where do we find it?

Context-aware information
It is widely available in various ways
interaction patterns, location, devices,
annotations, query suggestions and user
profiles
It is becoming more and more important
for
enhancement of retrieval performance and
recommendation results
personalization and adaptation of
information
