The proposed student model represents the observed characteristics and attitudes of the student when he comprehends a historical text and reflects the student's historical profile and his cognitive model. The student model was based on the Model Of Comprehension Of Historical Narration (MOCOHN) and on an experimental study of students' historical text comprehension. The experimental tool we have designed, considered as the core of the student diagnosis module of an intelligent tutoring system, can be exploited for inferring a student's cognitive state from his performance. The generalisation of the student model gives evidence for the dynamics of the constructed student model that can affect educational decisions in supporting individualised history teaching and tutoring.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116260620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reserves (a form of power supply insurance) are key to power system operability. Traditionally, reserves have been characterized in terms of time-domain quantities, such as ramping rate capabilities and the like. Also, traditionally such measures have not considered the possibility that some of the reserve services may be energy- or otherwise time-limited. This paper illustrates how to take into consideration energy-constrained reserve services, and also how to classify and measure both the need for reserves as well as the ability to provide them in terms of frequency-domain techniques. In a sense, the use of frequency-domain quantities is more \"natural\" for this problem where the characterization of the speed of response is in fact quite important. The paper illustrates a number of numerical examples.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125785269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, we have developed a database-driven system that will ultimately consist of more than 3000000 HTML documents, written in German, which are the empirical basis for our research. We introduce the notions of Web genre type which constitutes the basic framework for a certain Web genre, and compulsory and optional Web genre modules. These act as building blocks which go together to make up the structure characterised by the Web genre type and furthermore, operate as modifiers for the default assignment involved. The analysis of a 200 document sample illustrates our notion of Web genre hierarchy, into which Web genre types and modules are embedded. The analysis of four different documents of the Web genre Academic's Personal Homepage, not only illustrates our approach, but also our long-term goal of automatically extracting the contents of Web genre modules in order to build up structured XML documents of groups of unstructured HTML documents.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124525151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A relevant question to ask, though, is how systems and technology intended for information such as the intranet can be able to assist in the managing of knowledge. To understand this, we must examine the relationship between information and knowledge. Building on Polanyi's theories, the author argues that all knowledge is tacit, and what can be articulated and made tangible outside the human mind is merely information. However, information and knowledge affect one another. By adopting a multi perspective of the intranet where information, awareness, and communication are all considered, this interaction can best be supported and the intranet can become a useful and people-inclusive KM environment.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115768184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing online instructional management systems contain primitive discussion tools that do little to facilitate online interaction and collaborative discourse. This paper proposes the design of a new type of software - the TextWeaver/sup TM/ - to meet these needs. In particular, we illustrate improved design in four areas: reading and composing, message keywording and weaving, material storing and reusing, and working offline. The paper starts with an overview of existing network-based educational systems and discusses software design considerations for networked computers and related pedagogical principles. This is followed by a description of the proposed design of the TextWeaver/sup TM/ and a discussion of its pedagogical implications. We conclude with a discussion of evaluation strategies for the software, future directions for research, and a summary of our conclusions.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131040692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

XML evolved from standard generalised markup language (SGML) and became a World Wide Web Consortium (W3C) recommendation in February 1998. One of XML's main goals is to separate the structure and content of a document from its Web presentation. This means that virtually any application type irrespective of the presentation medium being used can read data in XML documents (www.w3.org). The critical enabler here is that XML is not a language per se but a standard for describing syntax that can be used to create particular vocabularies which can be shared by others (www.W3.org). Basically the structure and content of the data are defined once in a Document Type Definition (DTD) and an XML document, these can then be parsed and displayed in a myriad of ways by applying a particular stylesheet (XSL). The anticipated benefits of XML include easier integration of legacy systems, improved businessto-business communications, simplified delivery of management information and platform independence across the complete customer-supplier value chain (Information Age, August/September 2000) (Morrison et al, 2000) (Finkelstein & Aiken, 2000). These benefits are vital in the push for increased Internet services across a variety of business types and customers. If your business is involved with or is considering offering services and information through the Web, then XML should be investigated as a potential new strategy in your IT armoury (www.W3.org). This minitrack will look at the implications of XML on IT strategy and operations and how XML has been used in real world business applications. The minitrack will aim to provide IT managers with information on the benefits of XML and how it can be used as part of IT strategy development. Practical knowledge will also be provided for systems developers through the presentation of case studies involving XML designs and implementations. 0-7695-1435-9/02 $17.00 (c) 2002 IEEE 1 the 35th Annual Hawaii International Conference on System Sciences (HICSS-35’02) 02 $17.00 © 2002 IEEE","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126216551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The project ran two main studies with learning technology professionals. The key results emerging from this work are that different kinds of video clips were found to offer support for professional development needs. The subjects agreed that watching themselves in video clips was still a relatively novel experience and that using artifacts relating to the practice helped to 'ground' or anchor a representation in realistic ways for reflective learning. The studies found video clips and voice annotations could be rapidly created. Speed was seen as a significant benefit, and regarded as more important than creating a polished product, especially in fluid, evolving areas such as the learning technology field.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115989069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Network-centric approaches are particularly well suited for examining the social and technical dimensions of IT-enabled communication, such as those that occur via email, the Internet, intranets, electronic journals, and other collaborative communication technologies. A social network is a set of people, including organizations, connected by a set of social relationships. Information and communication technologies (ICTs) are increasingly integral to these networks. A sociotechnical network includes the technologies that sustain human interaction, and the technologies that people construct and use in collaboration. In socio-technical networks, the social and the technical are essentially inseparable and co-constitutive. The dynamics of these socio-technical networks are known to play a critical role in a number of diverse transformations, such as those that diffuse knowledge, invention and innovation from university scientists to industry entrepreneurs (and vice-versa.) Informational environments also constrain and enable collaborative interactions in such settings, and may attenuate or amplify the influence of ICTs. Researching the use of digital documents is an interesting way to engage the issues that surround the technical, geographic, social and economic dynamics that influence communications and collaborations within and among geographically and organizationally dispersed communities-of-practice. A focus on the use of these potentially malleable technologies may reveal more clearly how networked communities and informational environments differentially shape ICTs. This mini-track focuses attention on the use of networked information and communication technologies such as multimedia communication systems, remote sensing instruments, intranets and email, within and among communities-of-practice, such as research scientists, industrial researchers, consultants, and policy-setting groups. Our goal is to bring together researchers who are interested in the technical, geographic, social and economic dynamics that influence communications and collaborations among colleagues both within a community and across communities.

These digital documents include speech documents, and video and images as well as text documents in digital form. This minitrack focuses on how one gains an understanding of a digital document and how that information is communicated. It encompasses retrieval and text analysis methods, including summarization, catergorization, genre theory and detection, Web navigation and visualzation methods that increase understanding of document content and genre. This is the second year of this minitrack which is the result of merging two previous successful minitracks, Understanding and Visualization and Genre in Digital Documents. As such, there are continuing themes from both of the previous minitracks and from last year’s successful minitrack. This year there are two sessions. The first session has papers by Boongoen et al. and by Rehm. Both these papers attempt to “understand” documents but from very different approaches. Boongoen uses a network of agents and a natural language approach to extract knowledge from textual sources. The process is evolutionary in nature in that context gained from one document is used to help interpret the next document. Rehm’s approach is to identify the Web genre of documents. His approach is to view a genre as consisting of a set of sub-genres which can then be automatically identified and extracted from the main genre.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123443156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
