Creating a semantic-based discourse model for hypermedia presentations: (un)discovered problems
نویسندگان
چکیده
We address the problem of building a flexible discourse model that enables creation of relatively complex discourse structures by using a semantic framework and semantic descriptions of media items. With such model we intend to support different approaches to hypermedia presentation authoring. We give a short overview of existing hypermedia presentation generation systems and discuss what type of authoring they support. We present our motivation for working towards a discourse model that improves on existing approaches. We describe in more detail our experiences with various strategies for building discourse structures for DISC and SampLe systems. Based on these experiences we come up with a set of requirements for a common discourse model.

Clustering Semantics for Discourse Generation
In earlier work, we have shown how clustering techniques can transform semantic markup into discourse, which style sheets can transform into hypermedia presentations. This paper discusses the different clustering techniques for deriving discourse from semantics. These techniques use properties, relations and numerical properties of information objects and semantic networks. We show how these cl...
متن کاملExploiting Semantic Networks to Generate Hypermedia
Hypermedia is a hot research topic nowadays with a wide application domain In this paper we study the problem of generating hypermedia presentations from semantic network based repositories After discussing the application domain of this approach we focus on issues concerning the mapping of semantic networks to hypermedia structures In addition we present brie y our experiences from implementin...
متن کاملDiscourse knowledge in device independent document formatting
Most document structures define layout structures which implicitly define semantic relationships between content elements. While document structures for text are well established (books, reports, papers etc.), models for time based documents such as multimedia and hypermedia are relatively new and lack established document structures. Traditional document description languages convey domain-dep...
متن کاملBuilding Adaptive Information Presentations from Existing Information Repositories
1 Abstract In this paper we discuss issues that emerge in the attempt to integrate effectively techniques coming from Adaptive Hypermedia (AH) and Natural Language Generation (NLG) in order to reuse existing information to compose intelligent information presentations. In the solution we propose, NLG allows the generation of the most dynamic parts of the presentation i.e., with the selection of...
متن کاملPersonalization Functionality for the Semantic Web: Architectural Outline and First Sample Implementations
We propose a service–based architecture for bringing methods and techniques from the area of adaptive hypermedia to the Semantic Web. In our framework, personalization functionalities from adaptive hypermedia are available as web–services which a user can subscribe / un-subscribe as s/he likes. We have implemented our ideas in the Personal Reader, a framework for defining rule–based personaliza...
