6. 6 1. Adaptive HypermediaAdaptive Hypermedia Why, areas of application, what to adapt, Brusilovsky’s taxonomy, Adapt to what, (UM, GM, DM, Envir.) how to adapt, Brusilovsky’s loop, adaptability versus adaptivity, new solutions. You can be presented with a description of an application, and asked to describe it in terms of AH as above. E.g., what is Amazon book recommendation adapting to? What is being adapted? Etc.

7. 7 1. Personalization in e- CommercePersonalization in e- Commerce Benefits, perspectives, ubiquitous computing, b2b, b2c, CRM, CDI, pull, push, generalized, personalised recommendations, hybrid, latency (cold start), m- commerce Again, theory and application of theory in practice; e.g., a business personalization case is presented to you, and you are asked to describe it in terms of the newly learned acronyms and give the definitions. You would need to recognize from the description which apply and which not. E.g., is Amazon’s book recommender technique push or pull? Is b2b, b2c? Etc.

9. 9 2. User ModellingUser Modelling What, why, what for, how, early history, academic developments, what can we adapt to (revisited, extended – knowledge, cognitive, etc.), generic UM techniques, new developments Stereotypes, overlays, UM system, UM shell services + requirements (Kobsa), semantic levels of UM, deep- shallow UM, cognitive styles – Kolb, filed-dep-indep, intended/keyhole/obstructed plan recognition, moods and emotions, preferences UM techniques: rule-based, frame-based, network- based, probability, DT, sub-symbolic, example-based Challenges for UM UM server + requirements

10. 10 2. User ModellingUser Modelling Theory + application thereof either on a system you know, or on a system with a given description; e.g., is Amazon book recommendation based on UM shell services, or UM server – plus justification! Or: how would you extend the recommendation to cater for Kolb taxonomy’s active people?

Content alternatives, UM descript, presentation, adaptation tech., roles LAOS components and justification, LAG model layers and justification, LAG language : a small program – either to read or to write !! (based on programs you’ve been shown, and programs you’ve been asked to create for the coursework)
