“…Baldwin et al 57 propose a user modelling mechanism that can build user profiles by observing users' interaction with a computer system. While these projects consider modelling a user's cognitive state merely on a belief level, the learner models we have described in this paper incorporate learner's beliefs and misconceptions that provide possible 60 use CGs in a 'self-tutoring system' that generates questions to the user from given text lessons, analyzes the learner answers and generates adaptive feedback. All sentences in the lessons have to use Controlled English, which is the case with terminological texts.…”

This paper discussed the use of Conceptual Graphs (CGs) for implementing tasks employed in web-based educational systems that aid terminology learning. Specifically, we focus on two critical issues in intelligent tutoring -student diagnosis and generation of adaptive explanations. Both tasks are demonstrated in terminological domains where learners have to familiarize themselves with concepts in a specific subject area (e.g. computing, finance, chemistry). Based on CG reasoning, robust and computationally tractable algorithms for student modelling and adaptive explanation generation are defined. Two intelligent systems are presented -STyLE-OLM and HYLITE+. STyLE-OLM is an interactive learner modelling system that extracts extended models of the learners' cognition. HYLITE+ is a natural language generation system that generates adaptive Web pages based on a learner model(LM). The two systems are complementary and have been implemented separately. However, considered together they cover most of the key tasks in adaptive web-based educational hypermedia that aid learning technical terminology. Based on evaluative studies of STyLE-OLM and HYLITE+, the use of CGs for interactive open student modelling and adaptive concept explanations is examined. The applicability of CGs in adaptive web-based systems that aid learning technical terminology is discussed.
