Authoring of adaptive hypermedia comprises the design and creation process of adaptive hypermedia (AH): creation of content (usually in the form of a resource collection and domain model) and adaptive behaviour (usually in the form of IF-THEN rules; recently, adaptation languages have been proposed for increased generality; e.g., the (LAG language ) by Alexander I. Cristea et al., the (LAG-XLS language ) by Natalia Stash et al., etc.). As adaptive hypermedia adapts at least to the user, authoring of AH comprises at least a user model. Depending on the authoring framework used, different models of the static components to which an adaptation engine adapts can be represented and populated in the authoring process, such as presentation model, goal model, pedagogic model, etc. ==Issues== Authoring of adaptive hypermedia has been long considered as secondary to adaptive hypermedia delivery. This is not surprising in the early stages of adaptive hypermedia, when the focus was on research and expansion. Now that adaptive hypermedia itself has reached a certain maturity, the issue is to bring it out to the community and let the various stakeholders reap the benefits. However, authoring and creation of hypermedia is not trivial at all. Unlike in traditional authoring for hypermedia and the web, a linear storyline is not enough. Instead, various alternatives have to be created for the given material. For example, if a course should be delivered both to visual and verbal learners, there should be created at least two perfectly equivalent versions of the material in visual and in verbal form, respectively. Moreover, an adaptation strategy should be created that states that the visual content should be delivered to visual learners, whereas the verbal content should be delivered to the verbal learners. Thus, authors should not only be able to create different versions of their content, but be able to specify (and in some cases, design from scratch) adaptation strategies of delivery of contents. Issues with which authoring of adaptive hypermedia is confronted are: * creation of exchange language for the content (some early examples are (the CAM language )) * creation of exchange language for adaptation (with (the LAG language ) and the (LAG-XLS language ) as examples) * creation of a framework for adaptation (see, e.g., the (LAG framework )) * standardization of adaptation processes 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Authoring of adaptive hypermedia」の詳細全文を読む スポンサード リンク
