Searching Lifelong Learner Metadata Using Query Approximation and Relaxation

Trends in e-Commerce | Public Lecture in Business Informatics

Abstract

Supporting the needs of lifelong learners is leading to research into new learner-centred models of delivering learning resources and opportunities. In this direction, the L4All system aims to support lifelong learners in planning and reflecting on their learning. In this talk, some L4All system's facilities such as finding "people like me" based on string similarity metrics or "what next" for identifying possible future learning options will be described. The second part of the talk will explore more flexible querying techniques, which are based on a combination of query approximation and query relaxation techniques. They would provide users with more flexibility in formulating their requirements and exploring alternative formulations for the timeline search.
