TRUE: Traces for Reusing User Experience

International Workshop co-located with ICCBR-2012 September 3rd, 2012, Lyon, France

There has been a recent interest in artificial intelligence approaches based around traces. An important part of users; experience is stored in traces that record human activity, for example, when interacting with computer systems. Such traces record user interactions with a computer system through an application, a game, etc.

The opportunity to collect user experience as traces enables reusing those traces in CBR processes, since such traces capture user past experiences. Therefore, traces constitute a knowledge container from which a CBR process may buid and reuse cases or traces. The goal of the workshop is to gather and contrast approaches in exploiting numeric traces for various tasks and domains through CBR.

We welcome contributions in areas that include, but are not limited to, the following:

  • Collecting traces, building cases from traces
  • Modeling trace content, trace elements and cases
  • Provenance information regarding traces
  • Reasoning via user demonstrations/observations
  • Learning and adaptation of user traces
  • Novel applications of trace-based reasoning
  • Toolkits and/or methodologies for reasoning via traces
  • Architectures of trace reusing systems
  • Game playing via user traces
  • Tools for integrating trace-based techniques and gaming environments
  • Planning from user traces
  • Lessons learned from trace-based reasoning


This workshop will be held on September 3rd, 2012 as part of the ICCBR 2012 workshop series in Lyon, France. This workshop is open to all interested conference participants, but may be limited by available room facilities.

We plan to include an invited speaker to summarize recent work in this area and might also invite papers from a small but diverse set of contributors. The Organizing Committee will select a subset of the submitted papers for oral presentation. Finally, time will be reserved during the workshop where some participants can demonstrate their systems and illustrate the contributions of CBR technology.


We invite submissions of two types:

  • Research and application papers: a maximum of 10 pages describing original contributions.
  • Demonstration of trace-related CBR systems: a maximum of 5 pages describing the system

and why is it interesting for research on CBR.

Papers must be submitted in electronic form as PDF. Springer LNCS is the format required for the final camera-ready copy, Authors' instructions along with LaTeX and Word macro files are available on the web at Springer.
