This paper discusses concepts and terminology of some aspects of the laboratory diagnosis of liver (hepatic) disease and biliary tract disease (hepatobiliary disease) as it relates to medical reference work. Details of anatomic, biochemical, and pathologic processes are not discussed. Knowledge of the specific terminology involved in this area may help to ensure a good approach to developing prudent strategies for database searching of the medical literature and therefore is reviewed. MeSH and EMBASE thesauri terms are discussed and textword synonyms are presented that provide tools for thorough searching techniques. Commonly used medical jargon for this area is also explained. Examples of specific search strategies are illustrated. 相似文献

This paper provides an overview of the research into current medical vocabularies and their impact on searching the Web for health information. The Web provides growing opportunities for laypersons to gain knowledge about specific health conditions, though research to date has been incomplete. Many studies have examined aspects of controlled medical vocabularies. Other studies have examined aspects of medical Web searching vocabularies. In this context, there is a growing need to examine more closely laypersons' Web queries using controlled medical vocabularies that were designed to serve the needs of medical professionals. It may be the case that the average consumer of Web health services is not able to use correct medical terminology, and may not be able to choose analogous or synonymous terms from a search result list. Our review suggests a growing need for studies to examine the current applicability of controlled medical vocabularies as well as alternatives to semantic query by Web search engine users. 相似文献

Problems in online retrieval of information concerning medical devices are discussed, including background data regarding legislative history and terminology. An analysis of the results of searching on ten sample topics in this subject area provides a framework for approaching such problems. In addition to a consideration of recall, uniqueness, and overlap, other factors influence database selection and order of consultation. Indexing characteristics of selected health science, engineering, business, and regulatory databases play a major role in medical device information provision. 相似文献

OBJECTIVE: The article explores the characteristics of public health information needs and the resources available to address those needs that distinguish it as an area of searching requiring particular expertise. METHODS: Public health searching activities from reference questions and literature search requests at a large, urban health department library were reviewed to identify the challenges in finding relevant public health information. RESULTS: The terminology of the information request frequently differed from the vocabularies available in the databases. Searches required the use of multiple databases and/or Web resources with diverse interfaces. Issues of the scope and features of the databases relevant to the search questions were considered. CONCLUSION: Expert searching in public health differs from other types of expert searching in the subject breadth and technical demands of the databases to be searched, the fluidity and lack of standardization of the vocabulary, and the relative scarcity of high-quality investigations at the appropriate level of geographic specificity. Health sciences librarians require a broad exposure to databases, gray literature, and public health terminology to perform as expert searchers in public health. 相似文献

PURPOSE: The paper explores the current state of generalist search education in library schools and considers that foundation in respect to the Medical Library Association's statement on expert searching. SETTING/SUBJECTS: Syllabi from courses with significant searching components were examined from ten of the top library schools, as determined by the U.S. News & World Report rankings. METHODOLOGY: Mixed methods were used, but primarily quantitative bibliometric methods were used. RESULTS: The educational focus in these searching components was on understanding the generalist searching resources and typical users and on performing a reflective search through application of search strategies, controlled vocabulary, and logic appropriate to the search tool. There is a growing emphasis on Web-based search tools and a movement away from traditional set-based searching and toward free-text search strategies. While a core set of authors is used in these courses, no core set of readings is used. DISCUSSION/CONCLUSION: While library schools provide a strong foundation, future medical librarians still need to take courses that introduce them to the resources, settings, and users associated with medical libraries. In addition, as more emphasis is placed on Web-based search tools and free-text searching, instructors of the specialist medical informatics courses will need to focus on teaching traditional search methods appropriate for common tools in the medical domain. 相似文献

Successful subject searching depends upon the terminology of the search query. This paper compares the terminology of book titles with that of Library of Congress Subject Headings (LCSH) 1 on a semantic level. Methods of ananlyzing titles into title phrases that serve as matching units are described. Guidelines used to choose LCSHs with the closest semantic matches to title phrases are set forth. The pairing of title phrases with semantically related LCSHs constitutes the data of the study. Categories representing the types of semantic relationships holding between pairs of terms are defined. Results of the study show that the most common semantic relationship holding between title phrases and LCSH is a hierarchical one where title phrases are more specific than LCSHs. 相似文献

The relationship between the development of mediated online literature searching and the recruitment of medical librarians to fill positions as online searchers was investigated. The history of database searching by medical librarians was outlined and a content analysis of thirty-five years of job advertisements in MLA News from 1961 through 1996 was summarized. Advertisements for online searchers were examined to test the hypothesis that the growth of mediated online searching was reflected in the recruitment of librarians to fill positions as mediated online searchers in medical libraries. The advent of end-user searching was also traced to determine how this trend affected the demand for mediated online searching and job availability of online searchers. Job advertisements were analyzed to determine what skills were in demand as end-user searching replaced mediated online searching as the norm in medical libraries. Finally, the trend away from mediated online searching to support of other library services was placed in the context of new roles for medical librarians. 相似文献

A brief review of hospital library reference problems is presented. The essential problem in a one-person medical library is the time factor or time constraint under which appropriate answer to reference questions must be delivered. Various other common reference problems such as emergencies, misunderstood requests, ethical considerations of priorities, and the choice of computerized data base versus manual searching are discussed as they relate to the small medical library. Some reference aids are suggested as they apply to specific problems in cancer chemotherapy, syndrome identification, and adverse effects of drugs. A sampling of quick reference sources is included. 相似文献

Contemporary society and our educational institutions over-emphasize left-brained, analytical skills. This pervasive influence extends even into the library instruction classroom. This article calls for an adjustment of this left-brained paradigm, with a more holistic, right-brained, or “global” instructional approach. Background information is offered on split-brain theory, hemispheric function, and the importance of right-brain teaching techniques. The specific strategies of metaphor, visual thinking, direct experience, and fantasy are discussed with specific examples cited. A mind map, cluster diagram, and literature searching exercise are included. 相似文献

Ranking information resources is a task that usually happens within more complex workflows and that typically occurs in any form of information retrieval, being commonly implemented by Web search engines. By filtering and rating data, ranking strategies guide the navigation of users when exploring large volumes of information items. There exist a considerable number of ranking algorithms that follow different approaches focusing on different aspects of the complex nature of the problem, and reflecting the variety of strategies that are possible to apply. With the growth of the web of linked data, a new problem space for ranking algorithms has emerged, as the nature of the information items to be ranked is very different from the case of Web pages. As a consequence, existing ranking algorithms have been adapted to the case of Linked Data and some specific strategies have started to be proposed and implemented. Researchers and organizations deploying Linked Data solutions thus require an understanding of the applicability, characteristics and state of evaluation of ranking strategies and algorithms as applied to Linked Data. We present a classification that formalizes and contextualizes under a common terminology the problem of ranking Linked Data. In addition, an analysis and contrast of the similarities, differences and applicability of the different approaches is provided. We aim this work to be useful when comparing different approaches to ranking Linked Data and when implementing new algorithms. 相似文献

ABSTRACT The study investigated implications of variations in EAD-encoded finding aids on the Web. A content analysis methodology was used to examine five different aspects of EAD finding aids: (1) data elements; (2) labeling terminology; (3) navigation; (4) browsing; (5) searching. Seventeen EAD finding aid web sites selected from 161 RLG member institution web sites, were examined. The results of the study showed that variations in EAD finding aids existed. These include inconsistency in the use of data elements, labeling terminology, and browsing attributes. In addition, some of the EAD finding aid web sites did not provide navigational aids within a finding aid or search functions for access to it. Findings suggest that increased navigational aids, as well as more browsing and search functions are needed to provide better access to EAD-encoded finding aids. 相似文献
