SPIM workshop at ISWC

1. CROKODIL provides support for
the collaborative acquisition and
management of web resources
for learning purposes by
offering:
 Semantic tagging (tag types)
 Activity hierarchies to
structure these resources
 Learner groups

Personalized recommender systems
support learners by suggesting relevant
resources for learning purposes.
The challenge however, is identifying
these relevant resources considering the
learner’s personal context and needs.
To this aim, additional semantics found
in folksonomies can be exploited to
enhance the ranking of resources
Motivation
 Create a folksonomy-based
recommender system
 Rank resources considering
context semantics (Extension of
FolkRank)
 Integrate User Feedback and
Relevance Ranking (Rochio’s
approach)
 Offer explanations of
recommendations to stimulate
reflection
 Enrich recommendations with
external learning resources (OER)
Conceptual Approach
 Implement and
evaluate algorithms
 Integrate approach in
application scenario
 Evaluate approach
 Conduct usability
study to evaluate user
acceptance
