This paper reports on an investigation into a formal language for specifying KADS models of expertise. After arguing the need for and the use of such formal representations, we discuss each of the layers of a KADS model of expertise in the subsequent sections, and define the formal constructions that we use to represent the KADS entities at every layer: order-sorted logic at the domain layer, meta-logic at the inference layer and dynamic-logic at the task layer. All these constructions together make up (ML)2, the language that we use to represent models of expertise. We illustrate the use of (ML)2 in a small example model. We conclude by describing our experience to date with constructing such formal models in (ML)2, and by discussing some open problems that remain for future work. 相似文献

This article compares the hybrid constructions of race, gender, and culture offered by two Japanese magazines very similar in nature, although one is targeted at men, the other at women. Locating non-no and Men's non-no within a larger transcultural discourse of commodified cultural representation, this comparison reveals significant differences in the magazines’ constructions. While the magazines’ hybridities may offer opportunities for subversive gestures, their representations of race and gender are ultimately likely to legitimize longstanding power relations, both globally and locally. 相似文献

Creating a learnable, effective, and user-friendly library Web site hinges on providing easy access to search. Designing a search interface for academic libraries can be particularly challenging given the complexity and range of searchable library collections, such as bibliographic databases, electronic journals, and article search silos. Library Web designers must decide whether to present users with a single search interface—one that searches across content silos by default—or to offer an interface that exposes the various silos available. Designers must also contend with the user's entire search experience and determine how search should appear on the library home page as well as in global navigation systems. In the spring of 2010, the North Carolina State University Libraries sought to answer search design questions for an upcoming Web site design effort. The Libraries evaluated two different search interfaces to determine whether a tabbed search approach with options to pre-select silos is an effective design for end users. Findings show that a tabbed search interface is an effective design device for presenting multiple silos. This study outlines the methods the North Carolina State University Libraries used to conduct usability testing as well as observations, findings, and recommendations about effective design of search on academic library Web sites. 相似文献

The Internet has created new opportunities for librarians to present literature search results to clinicians. In order to take full advantage of these opportunities, libraries need to create locally maintained bibliographic databases. A simple method of creating a local bibliographic database and publishing it on the Web is described. The method uses off-the-shelf software and requires minimal programming. A hedge search strategy for outcome studies of clinical process interventions is created, and Ovid is used to search MEDLINE. The search results are saved and imported into EndNote libraries. The citations are modified, exported to a Microsoft Access database, and published on the Web. Clinicians can use a Web browser to search the database. The bibliographic database contains 13,803 MEDLINE citations of outcome studies. Most searches take between four and ten seconds and retrieve between ten and 100 citations. The entire cost of the software is under $900. Locally maintained bibliographic databases can be created easily and inexpensively. They significantly extend the evidence-based health care services that libraries can offer to clinicians. 相似文献

Background
Degenerative cervical myelopathy (DCM) is a recently proposed umbrella term for symptomatic cervical spinal cord compression secondary to degeneration of the spine. Currently literature searching for DCM is challenged by the inconsistent uptake of the term ‘DCM’ with many overlapping keywords and numerous synonyms.Objectives
Here, we adapt our previous Ovid medline search filter for the Ovid embase database, to support comprehensive literature searching. Both embase and medline are recommended as a minimum for systematic reviews.Methods
References contained within embase identified in our prior study formed a ‘development gold standard’ reference database (N = 220). The search filter was adapted for embase and checked against the reference database. The filter was then validated against the ‘validation gold standard’.Results
A direct translation was not possible, as medline indexing for DCM and the keywords search field were not available in embase . We also used the ‘focus’ function to improve precision. The resulting search filter has 100% sensitivity in testing.Discussion and Conclusion
We have developed a validated search filter capable of retrieving DCM references in embase with high sensitivity. In the absence of consistent terminology and indexing, this will support more efficient and robust evidence synthesis in the field. 相似文献17.

Comprehensive yet efficient search methods are essential for any systematic or scoping review. This article outlines the stages of development of a systematic search methodology for a scoping review within the library and information science (LIS) literature. The effectiveness of the database search strategies (LISTA, LISA, ERIC, Scopus, Web of Science) and supplemental search techniques are measured through a retrospective analysis of performance metrics. Findings show that for research topics limited to the library setting, it may be more effective to search fewer databases (LISTA and Scopus only) for peer reviewed journal articles and allot more time to alternate search techniques such as web searching to identify non-journal literature. The article provides an evidence-based, methodological approach to developing a systematic search plan, unique to LIS researchers, that accounts for time and resource needs. 相似文献

Objective: To identify or develop a critical appraisal instrument (CAI) to aid in the selection of search filters for use in systematic review searching. The CAI is to be used by experienced searchers without specialized training in statistics or search filter design. Methods: Through extensive searching and consultation, one candidate instrument was identified. Through expert consultation and several rounds of testing, the instrument was extensively revised to become the Canadian Agency for Drugs and Technologies in Health (CADTH) CAI. Results: The CADTH CAI consists of ten questions and can be applied by experienced searchers with a moderate knowledge of search filter methodology. Conclusion: The CADTH CAI provides experienced searchers with a means of selecting the search filter that is most methodologically sound. 相似文献
