Authoring


Regular learning material• Linear• One story line• Granularity doesn’t matter• Reuse is no issue (normally)• Book-like structure


Intelligent learning material• Non-Linear• Several story lines• Granularity does matter• Reuse is an issue • Hypermedia-like structure

• so …


Authoring ILS, AHS• content alternatives, : domain model• adaptation techniques & : adaptation model• whole user-description design : user model

• complicated heavy task => authors require help, guidelines & automation facilities.

• for AHS to spread widely => facilitate author work (Open Learning Repositories)


Authoring & standardization

• Formalization attempts: – standardising the whole procedure

• Research on a systematic base– clear explicit models for adaptive authoring


Authoring perspectives

• Conceptual view: defining concepts, interrelationships and resources.

• Navigational (goal) view: defining pages content and navigation behavior.

• Presentation view: defining presentation aspect like frame, frameset, and window.

Title: Adaptive Hypermedia

Introduction: Adaptive Hypermedia deals with personalization and adaptation in hypertext and hypermedia.

Keywords: adaptive; hypermedia; hypertext; personalization

Conclusion: Adaptive Hypermedia deals with personalization and adaptation in hypertext and hypermedia.

Text: Adaptive Hypermedia is a special type of hypermedia that customizes the information that each user receives. Based on an interpretation of the user’s current needs, interests, goals, knowledge, etc., adaptive hypermedia systems provide the users with information ...

Authoring Roles – regular LM• Author performs all (or at least most of)

the tasks required in creation of the learning material


Authoring Roles – intelligent LM• Author could perform all (or at least most of) the

tasks required in creation of the learning material

• Ideally, authoring roles would be applicable, depending on the specialization of the author– Domain– Adaptation mechanism– Meta-data– etc.


Conclusion authoring• The tasks are divided• The domain is restructured and divided• A lot of new components emerge

• So we need a framework to describe this new structure
