Motivation
• Creation of adaptive content is crucial to the popularisation of A(E)H.
• 2 separate challenges for Authoring AH– Content Creation– Strategy Creation
• MOT focuses on Content Creation

LAOS Framework• Hierarchy of concepts
• Each concept contains attributes
• Standard attributes include:• Title (required)• Text• Keywords• Exercise• Introduction• Conclusion
Domain Model

LAOS Framework
Goal Model
• Hierarchy of sublessons (or groups of sublessons)
• Each sublesson is a link to a concept attribute
• Sublessons (or groups) can be labelled/weighted

LAOS Framework• Content in concepts and attributesDomain Model
• Describes goals of lessonGoal Model
• Stores data about userUser Model
• Strategy for showing/hiding contentAdaptation Model
• How the content is shownPresentation Model

Semi-Automatic Authoring
• Focus on reusing existing content– MediaWiki– Microsoft PowerPoint
![Page 12: Adaptive Hypermedia Content Authoring using MOT3.0 Jonathan G. K. Foss Dr. Alexandra I. Cristea](https://reader036.vdocuments.mx/reader036/viewer/2022062511/55160e4b550346d46f8b611b/html5/thumbnails/12.jpg)
MediaWiki Importer
• Extracts concepts from WikiText
• Parses other WikiText into HTML then stored in text attribute
![Page 13: Adaptive Hypermedia Content Authoring using MOT3.0 Jonathan G. K. Foss Dr. Alexandra I. Cristea](https://reader036.vdocuments.mx/reader036/viewer/2022062511/55160e4b550346d46f8b611b/html5/thumbnails/13.jpg)
Presentation Importer
• Files converted using OpenOffice.org
• Each slide creates a concept with attributes:– Text– Image– Notes
![Page 14: Adaptive Hypermedia Content Authoring using MOT3.0 Jonathan G. K. Foss Dr. Alexandra I. Cristea](https://reader036.vdocuments.mx/reader036/viewer/2022062511/55160e4b550346d46f8b611b/html5/thumbnails/14.jpg)
Future Research
• Extend MediaWiki importer– Extract keywords from articles– Crawl/Import related topics
• How deep?! Six Degrees of Seperation?
