- Abstract
- This paper presents our approach of using hypertext representations to support a scholar in the early stages of a scholarly writing process. We take D. A. Schoen's model of design as a theoretical framework. Schoen views design as a reflective conversation with the materials of a situation, where the designer interacts with the materials, such as pen and sketch on a sheet of paper, in the reflection-in-action process. The designer acts and reflects almost simultaneously; acting on external representations, interpreting emerging representations, and reacting to them. We argue that a scholar needs to engage in two different types of representations in the reflection-in-action process: external representations for thinking about the problem, and representations for expressing a solution in a publishable form. The former does not necessarily precede the latter; rather, the two representations coevolve through the reflection-in-action process. Our approach uses hypertext representations as a means to interact with in the early stages of scholarly writing both for thinking about the problem and for expressing a solution. Hypertext representations have long been studied in their relation to supporting human intellectual work; our approach, however, is unique in providing the two representations with a specific concern for supporting reflection-in-action by applying the concept called ART (Amplifying Representational Talkback) as an interaction design principle. Based on this framework, we have developed ART014, a tool for scholarly writing. ART014 simultaneously supports two types of hypertext representations: a column-based network hypertext representation and a spatial hypertext representation. The two representations are located side by side, and integrated when an interaction with one representation is reflected in the visual presentation of the other. Although a user operates on the same set of objects through the two representations, the user expresses relationships among the objects independently in the two representations. We present a scenario to illustrate in detail how the design concepts underpinning ART014 supports scholarly writing. This paper then discusses our approach from three viewpoints by using the scenario: use of the two representations, engagement in reflection-in-action, and modes of authoring. The paper concludes with a description of future directions.

- Abstract
- The paradigm shift from the old system centered view to a user centered approach involves new tools needed for accessing library resources under the condition that the user's needs are taken into account. An end-user, who has only a little knowledge of classification systems or thesauri, understands little of the mode of the representation of contents and the use of authority lists. In addition, he will have difficulty in formulating his question in a precise manner. He needs to know better what the library proposes in order to define of what use it would be for him. Many studies have been carried out on the use of controlled vocabularies (classification, authority lists, thesauri) as searching devices. It is surprising to find that relatively little attention has been given to the role of these tools in filtering and browsing processes. We have developed a prototype named CATHIE (CATalog Hypertextuel Interactif et Enrichi) that supports such filtering and interactive reformulation features

- Abstract
- Fast, effective, and adaptable techniques are needed to automatically organize and retrieve information an the ever-increasing World Wide Web. In that respect, different strategies have been suggested to take hypertext links into account. For example, hyperlinks have been used to (1) enhance document representation, (2) improve document ranking by propagating document score, (3) provide an indicator of popularity, and (4) find hubs and authorities for a given topic. Although the TREC experiments have not demonstrated the usefulness of hyperlinks for retrieval, the hypertext structure is nevertheless an essential aspect of the Web, and as such, should not be ignored. The development of abstract models of the IR task was a key factor to the improvement of search engines. However, at this time conceptual tools for modeling the hypertext retrieval task are lacking, making it difficult to compare, improve, and reason an the existing techniques. This article proposes a general model for using hyperlinks based an Probabilistic Argumentation Systems, in which each of the above-mentioned techniques can be stated. This model will allow to discover some inconsistencies in the mentioned techniques, and to take a higher level and systematic approach for using hyperlinks for retrieval.

- Content
- This article reports an applied research on the construction and implementation of a semantically structured conceptual prototype to help in the organization and representation of human knowledge in hypertextual systems, based on four references: the Facet Analysis Theory (FAT), the Conceptual Map Theory, semantic structure of hypertext links and the technical guidelines of the Associacao Brasileira de Normas Técnicas (ABNT). This prototype, called Modelo Hipertextual para Organizacao de Documentos (MHTX) - Model For Hypertext Organization of Documents HTXM - is formed by a semantic structure called Conceptual Map (CM) and Expanded Summary (ES), the latter based on the summary of a selected doctoral thesis to which access points were designed. In the future, this prototype maybe used to implement a digital libraty called BTDECI - UFMG (Biblioteca de Teses e Dissertacöes do Programa de Pós-Graduacao da Escola de Ciência da Informacao da UFMG - Library of Theses and Dissertations of the Graduate Program of School of Information Science of Universidade Federal de Minas Gerais).
