Enhancing Authoring Efficiency Through Interoperability in Multiple AEH Systems

This paper discusses the importance of interoperability in addressing the high cost of authoring in Adaptive Educational Hypermedia (AEH) systems, ensuring content remains relevant amidst rapid developments. It explores the many-to-many paradigm, conversion and lingua franca approaches, and interoperability of materials, content, user models, and presentation. A comparison of MOT and WHURLE user models, transfer of user models, conceptual conversion, and additional user information is examined. The potential methods for achieving user interoperability, such as middleware or standard user models, are considered, along with the need for a core set of variables. A common data storage framework for system-specific data is proposed.

  1. Interoperability as an Aid to Authoring:Accessing User Models in Multiple AEH SystemsIlknur Celik1, Craig Stewart2 and Helen Ashman11 School of Computer Science and Information Technology, University of Nottingham, Jubilee Campus, Wollaton Road, Nottingham, NG8 1BB, UK{ixc,hla}@cs.nott.ac.uk2 Department of Electronic Engineering, Queen Mary, University of London Mile End Road, London, E1 4NS, UKcraig.stewart@elec.qmul.ac.uk

  2. Introduction • The need for interoperability: • High cost of authoring for AEH • Authored content becoming outdated • Rapid rate of developments in AEH

  3. Our Approach • The ideal many-to-many paradigm • The conversion and lingua franca approaches • Interoperability of materials, content, adaptation rules, user models and presentation

  4. High Level Comparison of MOT and WHURLE User Models

  5. Transfer of UMs from MOT to WHURLE

  6. Conceptual Conversion Commonalities MOT UM WHURLE UM Additional User Info: Password … Additional User Info: DoB Address Gender … User ID Additional Lesson Info: Next lesson Test (pre- and post-) Score Lesson closing date … UserName Additional Domain Info: Concept Access Attribute name … Fore Name Family Name Lesson Domain Additional Lesson Info: Teacher name … Additional Presentation Info: Configuration name Configuration file … Stereotype Knowledge Additional Presentation Info: Machine type Min character size …

  7. Discussion • Interoperability of users can be achieved either: • With a middleware program, or • By building a standard user model • Extract common factors • Some UM variables have no equivalent • A core set of variables is needed • Assumptions • A common data storage framework to retain the system specific data
