Abstract. This paper characterises weaknesses in the ability of current digital libraries to support scholarly inquiry, and as a way to address these, proposes services grounded in semiformal models of the naturalistic argumentation commonly found in research literatures. It is argued that a design priority is to balance formal expressiveness with usability. We summarise the requirements for an argument modelling scheme for use by untrained researchers, describe the resulting scholarly discourse taxonomy, contrast it with other domain modelling and semantic web approaches, before focusing on examples of computational services to support the filtering and analysis of the repository. 1 1

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 a 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.

The creation, management and dissemination of bibliographic information is a common task for almost all people working in a research environment, and it also is a (often weak) way of knowledge management. Current tools and methods are either centered on the process of document preparation using bibliographic references, or on the aspect of creating annotations and/or relationships describing bibliographic resources. As a result, bibliography management in many cases is still carried out with fairly simple tools and methods, and with little or no support for sharing the information. In the ShaRef project, the areas of document preparation, knowledge management, and information sharing among workgroup members are treated as equally important. As a result, ShaRef enables users to create, manage, and disseminate bibliographic information in a wide variety of use cases.

Managing bibliographic data is a requirement for many researchers, and in the group setting within which the majority of research takes place, the managing and sharing of bibliographic data is an important facet of organizing the research work. Managing and sharing bibliographies has to balance di#erent levels of shared access (public catalogs, closed research group bibliographies, and personal bibliographies), and the sharing platform should integrate as seamlessly as possible into diverse environments in terms of operating systems, document processing, and other information management tools. The ShaRef system presented in this paper has been designed to fill the gap between public libraries and personal bibliographies, and provides an open platform for sharing bibliographic data among user groups. Through its simple and flexible data model and system architecture, ShaRef adapts to many settings and requirements, and can be used to increase collaboration and information flow within groups.

A problem facing many textbook authors (including one of the authors of this paper) is the inevitable delay between new advances in the subject area and their incorporation in a new (paper) edition of the textbook. This means that some textbooks are quickly considered out of date, particularly in active technological areas such as the Web, even though the ideas presented in the textbook are still valid and important to the community. This paper describes our approach to building a companion website for the textbook Hypermedia and the Web: An Engineering Approach. We use Bloom's taxonomy of educational objectives to critically evaluate a number of authoring and presentation techniques used in existing companion websites, and adapt these techniques to create our own companion website using Semantic Web technologies in order to overcome the identified weaknesses. Finally, we discuss a potential model of future companion websites, in the context of an e-publishing, e-commerce Semantic Web services scenario.

This article characterizes key weaknesses in the ability of current digital libraries to support scholarly inquiry, and as a way to address these, proposes computational services grounded in semiformal models of the naturalistic argumentation commonly found in research literatures. It is argued that a design priority is to balance formal expressiveness with usability, making it critical to coevolve the modeling scheme with appropriate user interfaces for argument construction and analysis. We specify the requirements for an argument modeling scheme for use by untrained researchers and describe the resulting ontology, contrasting it with other domain modeling and semantic web approaches, before discussing passive and intelligent user interfaces designed to support analysts in the construction, navigation, and analysis of scholarly argument structures in a Web-based environment. © 2007 Wiley Periodicals, Inc.

Abstract—The paper argues that automatic link generation and typing methods are needed to find and maintain crossdocument links in large and growing textual collections. Such links are important to organise information and to support search and navigation. We present an experimental study on mining cross-document links from a collection of 5000 documents. We identify a set of link types and show that the value of semantic similarity is a good distinguishing indicator. Keywords-text mining, automatic link generation and typing, semantic similarity, digital libraries I.
