ADS expert     
ADS Expert is an integrated system that (a) provides suggestions about suitable optimization algorithms for a particular structural optimization problem, (b) it offers explanations and guide lines, in the form of hypertext, that refer to the optimization strategy, optimizer and one dimensional search method, (c) it produces the required gradients for the objective function and the constraints using symbolic differentiation, (d) establishes a direct linking with ADS routines and (e) it monitors the evolution of the optimization process. The system can be used as an educational tool for structural optimization and as an efficient integrated system for small to medium size optimization problems for which the objective function and the constraints are given in the form of explicit functions of the design variables. The system is a Windows application and runs quite satisfactorily on PCs.  相似文献

There are many studies that offer different opinions on the effects of hypertext usage as an educational tool. Given the differences of opinion, it is useful to research the effects of metaphor usage in hypertext education and the use of hypertext as an educational tool. In this study, the effects of metaphors' uses in constructing the characteristics of the hypertext teaching have been approved. A between-group design experiment was conducted to study the effects of four metaphors on four different groups. Survey results emphasise the importance of metaphor usage and the manner in which metaphor is used. It was also discovered that metaphor usage in the hypertext teaching affects the construction duration of the hypertext but does not have any effects on the acquisition of knowledge.  相似文献

Our overall research goal is providing hypertext functionality through the WWW to hypertext-unaware information systems with minimal or no changes to the information systems. Information systems dynamically generate their contents and thus require some mapping mechanism to automatically map the generated contents to hypertext constructs (nodes, links, and link markers) instead of hypertext links being hard-coded over static contents. No systematic approach exists, however, for building mapping routines to create useful links that give users direct access to the ISs' primary functionality, give access to metainformation about IS objects, and enable annotation and ad hoc (user-declared) linking. This paper contributes a procedure for analyzing ISs and building mapping routines that supplement information systems with hypertext support. This paper also contributes an eXtensible Markup Language (XML) DTD that declares a set of elements and attributes for representing mapped information in a human-readable, machine-readable, structured, and semantic way. We implemented a prototype to demonstrate the feasibility of using XML to represent mapped information.  相似文献

The electronic generation of documents in modern offices will trasform the nature of archives, and also the techniques of historical research. Although considerable attention has been directed to developing research methodologies for social and economic history using computerized numeric data, almost no attention has been paid to the impact of machine readable textual records on historical writing. This article considers the advantages and disadvantages for the historian of the shift from paper records to electronic documents, and suggests a number of approaches to historical research made possible by the new technology. Ronald Zweig is a graduate of the University of Sydney (Australia) and Cambridge University (UK). He is currently a Senior Lecturer in Jewish History, and Chairman of the Computing Committee, Faculty of Humanities, Tel Aviv University. He is the author of Britain and Palestine the Second World War;and German Reparations and the Jewish World;he is also editor of David Ben-Gurion: Political Leadership in Israel,as well as the journal Studies in Zionism.  相似文献

Adaptive Hypermedia   总被引:7,自引:2,他引:7  
Adaptive hypermedia is a relatively new direction of research on the crossroads of hypermedia and user modeling. Adaptive hypermedia systems build a model of the goals, preferences and knowledge of each individual user, and use this model throughout the interaction with the user, in order to adapt to the needs of that user. The goal of this paper is to present the state of the art in adaptive hypermedia at the eve of the year 2000, and to highlight some prospects for the future. This paper attempts to serve both the newcomers and the experts in the area of adaptive hypermedia by building on an earlier comprehensive review (Brusilovsky, 1996; Brusilovsky, 1998).  相似文献

Hypertext functionalities represent a form of the distilled wisdom of the hypermedia community. Even if they were introduced and advocated already in the pre-Web era, most of these functionalities are absent in current Web browsers. However, such functionalities can be very useful in some specific applicative fields, like for instance browsing complex software engineering documents, using standard WWW components. We propose to exploit the advent of XML as a basic infrastructure for describing software engineering hypertexts. In fact, we describe XMLC, a prototype of an XML browser that, given its modular architecture and general scope, can be seen as the basis for implementing sophisticated hypertext functionalities for software engineering documentation to be maintained and browsed on the Web.  相似文献

There is more to legal knowledge representation than knowledge-bases. It is valuable to look at legal knowledge representation and its implementation across the entire domain of computerisation of law, rather than focussing on sub-domains such as legal expert systems. The DataLex WorkStation software and applications developed using it are used to provide examples. Effective integration of inferencing, hypertext and text retrieval can overcome some of the limitations of these current paradigms of legal computerisation which are apparent when they are used on a stand-alone basis. Effective integration of inferencing systems is facilitated by use of a (quasi) natural language knowledge representation, and the benefits of isomorphism are enhanced. These advantages of integration apply to all forms of inferencing, including document generation and casebased inferencing. Some principles for development of integrated legal decision support systems are proposed.  相似文献
