  1. Validating the Evaluation of Adaptive Systems by User Profile Simulation Javier Bravo and Alvaro Ortigosa {javier.bravo, alvaro.ortigosa}@uam.es Universidad Autónoma de Madrid

  2. Motivation • Evaluation of AHS is a difficult task. • Log analysis tools can be used to support (semi) automatic evaluation of AHS. • Look for anomalous behavioral patterns that may point to problems on the adaptation rules. • Requirement: these tools should also be validated! • The validation process itself is a difficult task • A large set of student logs is needed to test the evaluation tool.

  3. Main Goals • Evaluation tools integrated into the AHS architecture. • Provide to the course designer a tool to test if the evaluation works correctly: all anomalous patterns are detected • Use simulation techniques to test the tool. • Classify the anomalies.

  4. Evaluation Based of Student Data

  5. Approach of Validating the Evaluation

  6. Conclusions and Future Work • This approach propose a practical way to test an evaluation tool based on log analysis. • Future work includes: • Testing SIMULOG with real designers • It is the ontology complete enough? • Checking SIMULOG results against real user logs • Creating an ontology for adaptive course description.

  7. Thank you • If you have any questions, I will be next to the poster.
