Agenda Adaptation process modeling AH classification and adaptation cycle AHS evolution GAF layers Generic Flowchart GAF sequence chart Use-cases Conclusions / Department of Computer Science PAGE

Adaptation process modeling: / Department of Computer Science PAGE Classic loop user modeling - adaptation Munich Model: Lifecycle of Adaptation Generic Adaptivity Model GOMAWE

Classification of AH methods and techniques; adaptation process highlights: / Department of Computer Science PAGE Classification of AH methods and techniques integrated with adaptation process cycle Basis for the AHS layered structure

AHS evolution: / Department of Computer Science PAGE Generalize AHS functionality in GAF Enhance GAF layered structure with the process Generalize adaptation process in GAF

Rotating GAF layered model: / Department of Computer Science PAGE GAF aligns the order of the layers in the system according to the classification of AH methods and techniques Rotate layered structure of GAF and match with adaptation process flowcharts GAF layered structure

Adaptation process: Generic representation of the process Aligned it with the traditional ‘adaptation questions’ Provides a flowchart diagram of a generic AHS Align the layers of AHS in a sequence chart Matched flow and sequence charts Reference Adaptation Process / Department of Computer Science PAGE 625/07/2014

Generic Flowchart (example) : / Department of Computer Science PAGE main blocks: goal acquisition, adaptive functionality test-feedback loop Mapped on the layered structure of GAF model Mapped on the Adaptation process sequence chart (see process numbers and GAF sequence chart further)

Key elements of GAF sequence chart: Layered structure preserved in a sequence Layers aligned with adaptation questions Layers aligned with process and generic flowchart Layers determine (de) composition of the GAF model / Department of Computer Science PAGE

Use-case 1: Adaptive course: / Department of Computer Science PAGE Generic Flowchart compliance  ‘next’ goal / concept / test main loop  granularity module  concept-content adaptation sequence  presentation generation

Use-case 2: WWW Search: Sequence chart (GAP) compliance with the search process: Goal Model – defines search query Domain Model – defines search index Resource model - WWW Context Models – defines user and usage context properties (IP, user profile, etc.) Group Model – defines user collaborative profile Adaptation and Application models – define search engine and ranking mechanisms / Department of Computer Science PAGE

Use-case 2: WWW Search sequence chart: / Department of Computer Science PAGE

Conclusions: Generic Adaptation Process Conformity of the adaptation process sequence and flowchart approaches Layered process-based (de)composition of an adaptive system Building Block of a User-Adaptive System process / Department of Computer Science PAGE

Further work: Elaborate process description and extend generic adaptation process emphasizing new developments in AH Align adaptation sequence chart with other user- adaptive systems (e.g. Recommender systems) Emphasize interoperability of the new AH developments in the context of the process (e.g. open corpus adaptation, higher order adaptation, etc.) / Department of Computer Science PAGE
