《Knowledge Acquisition》1994,6(1):47-74
Knowledge acquisition is a modeling activity for the development of knowledge-based systems. Developers can take advantage of domain-specific knowledge-acquisition tools for the construction of knowledge bases. Modeling for the development of such tools is an activity that is analogous to the modeling for knowledge-based systems. However, there are important differences between the appropriate models for these two goals. The models for the development of domain-specific knowledge-acquisition tools involved can be divided into three major classes: knowledge-structure models, knowledge-acquisition models and design models. These models can help developers to create domain-specific tools for new application domains. 相似文献

Satisfying clinical information needs remains a major challenge in medicine, underscored by recent studies showing high medical error rates and suboptimal physician adherence to evidence-based practice guidelines. Advanced clinical decision support systems can improve practitioner performance and patient outcomes. Similarly, integrating online information resources into electronic health records (EHRs) shows great potential for positively impacting health care quality. This paper explores the evolution and current status of knowledge-based resource linkages within EHRs, including the benefits and drawbacks, as well as the important role librarians can play in this process. 相似文献

《Knowledge Acquisition》1993,5(1):79-116
Many efforts in knowledge acquisition are designed from a knowledge engineer's perspective and as a consequence fall short of allowing experts to elaborate successfully their own situated knowledge. Knowledge engineering approaches are typically not user-centered and consequently are often the cause of a bottleneck in system development. This paper describes and evaluates the Advanced Knowledge And Design Acquisition Methodology (AKADAM) project as an attempt to overcome such inadequacies by provision of user-centered knowledge acquisition techniques. Both theoretical and practical issues are examined. The role of multiple perspectives (i.e. "knowledge as rules", "knowledge as concepts", and "knowledge as designs"), their relationship to a user-centered approach, and the necessity of flexible knowledge integration are portrayed by applying AKADAM to a complex, real-world domain (i.e. the development of an electronic associate for fighter pilots). Results suggest that this approach is capable of providing: (a) a naturalistic knowledge elicitation environment endorsed by users, (b) an externalization of experts' intuitive knowledge in a form which is similar to their own mental representation and (c) an integrated, large-scale knowledge set suitable for infusing knowledge into AI architectures and human-computer interface design. 相似文献

文章利用“中国知网”以及其他数据源,对国内期刊1993年至今公开发表的知识元相关研究的文献进行调研,从理论探索与实践成果两个方面,对研究现状进行了分析,认为国内知识元相关研究取得了不俗的成绩,将知识元的理论应用于中文知识管理是切实可行的,但同时在知识元研究范畴、粒度把握、知识元构建方面还存在一系列问题,有待进一步深入研究。 相似文献

建立整合的知识结构贮藏库(英文) 总被引：2，自引：0，他引：2
不同的知识库对概念的语义与词义的表达都会不同。用户要在检索中使用它们就会有困难。该论文介绍了一个知识贮藏库的整合模型。这个模型全部利用开放式软件(Open-SourceSofware)以及可扩展标记语言(XML)和概念分类体系(Ontologies)的技术建成。它提供了知识库之间的知识结构映射,也为用户提供图表式界面以方便用户对知识库整合的直接参与。由于这一模型是以用户为中心,以知识结构为重点,它将为建立下一代的知识网络提供一个范例。 相似文献

This paper discusses the problem of joining production rules obtained from knowledge sources of different typology (experts, problem-oriented texts, electronic carriers in the form of databases) with a view to building complete and consistent knowledge bases in integrated expert systems. It describes the properties of distributed knowledge acquisition within the target-oriented methodology for building integrated expert systems and automatic technology created on its basis that includes new-generation instruments - an AT-TECHNOLOGY software complex. The problems of using the theory of multisets to join productive rules obtained from different knowledge sources are considered. 相似文献

This paper concerns a new class of systems that are, on the one hand, dynamic systems, and on the other, intelligent systems,
as their dynamics is described by knowledge representation, which is a common practice to use in intelligent systems, and
the states are described by parameters and variables that have a logical or linguistic character. The case is considered when
the rule system is used as a method of knowledge representation. 相似文献

The objectives of this study were to determine nurses' use of electronic databases to inform practice. A questionnaire survey of 114 nurses working on five acute wards in a large inner city teaching hospital investigated their general use of computers and the three databases, CINAHL, MEDLINE and the Cochrane Library. Eighty-two qualified nurses responded (response rate 72%). The results show limited confidence and low frequency in using the databases. Thirty-four per cent expressed low confidence using CINAHL. Twenty-seven per cent used CINAHL on a regular basis. Twenty-two per cent never used it. Eighteen per cent were unaware that it was available locally. Knowledge and use of MEDLINE was even lower with only 18% using it regularly. Knowledge of the Cochrane Library was extremely limited, with 75% unaware of its existence. Use of a home computer and higher education were associated with higher frequency of use of CINAHL and MEDLINE. If nurses are to make use of electronic resources to contribute to evidence-based practice, effort needs to be put into ensuring that already qualified nurses have basic computer skills and specific knowledge of available resources. More emphasis should be placed on 'evidence-based' resources, such as the Cochrane library, as sources of information for practice. 相似文献

Health sciences librarians at the University of Washington (UW) are partners in the evolution of Internet-based clinical information systems for two medical centers, University of Washington Medical Center and Harborview Medical Center, as well as the UW Primary Care Network clinics. Librarians lead information resource and systems development projects and play a variety of roles including facilitator, publisher, integrator, and educator. These efforts have been coordinated with parallel development efforts by the Integrated Advanced Information Management Systems (IAIMS) clinical informatics group in developing electronic medical record systems and clinical decision support tools. The outcome is MINDscape, a very heavily used Web view of the patient medical record with tightly integrated knowledge resources as well as numerous Web-accessible information resources and tools. The goal of this article is to provide a case study of librarian involvement in institutional information systems development at UW and to illustrate the variety of roles that librarians can assume in hospital settings. 相似文献
