Author keywords for scientific literature are terms selected and created by authors. Although most studies have focused on how to apply author keywords to represent their research interests, little is known about the process of how authors select keywords. To fill this research gap, this study presents a pilot study on author keyword selection behavior. Our empirical results show that the average percentages of author keywords appearing in titles, abstracts, and both titles and abstracts are 31%, 52.1%, and 56.7%, respectively. Meanwhile, we find that keywords also appear in references and high-frequency keywords. The proportions of author-selected keywords appearing in the references and high-frequency keywords are 41.6% and 56.1%, respectively. In addition, keywords of papers written by core authors (productive authors) are found to appear less frequently in titles and abstracts in their papers than that of others, and appear more frequently in references and high-frequency keywords. The percentages of keywords appearing in titles and abstracts in scientific papers are negatively correlated with citation counts of papers. In contrast, the percentages of author keywords appearing in high-frequency keywords are positively associated with citation counts of papers.  相似文献

ABSTRACT

The authors updated their 2009 article on the MLA International Bibliography (MLAIB) by comparing it across three vendor platforms to determine if seemingly comparable searches continued to produce varying results. As much as possible, the authors tested the same searches as were tested in the original article and added additional ones for further exploration. Findings illustrate that while there are fewer differences than was the case previously, differences still exist. The authors also investigated discovery services to identify factors affecting MLAIB searches. The authors discuss the impact of their findings on users, from undergraduates to faculty researchers.  相似文献

Abstract

This research project explores how to ethically, efficiently, and accurately add demographic terms for African American authors to catalog records. A Department of History graduate student located evidence of self-identification as African American for authors, and catalogers added the demographic term to bibliographic records and are in the process of creating work level Name Title Authority Records for titles written by those authors. This work is the beginning of systematically enhancing catalog data with author characteristics to support making such information available in faceted results.  相似文献

ABSTRACT

The authors of this article analyzed the differences in output when searching MEDLINE direct and MEDLINE via citation management software, EndNote X1®, EndNote Web®, and RefWorks©. Several searches were performed on Ovid MEDLINE and PubMed directly. These searches were compared against the same searches conducted in Ovid MEDLINE and PubMed using the search features in EndNote X1, EndNote Web, and RefWorks. Findings indicated that for in-depth research users, should search the databases directly rather than through the citation management software interface. The search results indicated it would be appropriate to search databases via citation management software for citation verification tasks and for cursory keyword searching.  相似文献

Objective:A growing volume of studies address methods for performing systematic reviews of qualitative studies. One such methodological aspect is the conceptual framework used to structure the review question and plan the search strategy for locating relevant studies. The purpose of this case study was to evaluate the retrieval potential of each element of conceptual frameworks in qualitative systematic reviews in the health sciences.Methods:The presence of elements from conceptual frameworks in publication titles, abstracts, and controlled vocabulary in CINAHL and PubMed was analyzed using a set of qualitative reviews and their included studies as a gold standard. Using a sample of 101 publications, we determined whether particular publications could be retrieved if a specific element from the conceptual framework was used in the search strategy.Results:We found that the relative recall of conceptual framework elements varied considerably, with higher recall for patient/population (99%) and research type (97%) and lower recall for intervention/phenomenon of interest (74%), outcome (79%), and context (61%).Conclusion:The use of patient/population and research type elements had high relative recall for qualitative studies. However, other elements should be used with great care due to lower relative recall.  相似文献

ABSTRACT

British translator and publisher of Russian technical literature Eugene Gros, evidently of Czech origin, collected over two thousand titles published in the Soviet Union from approximately 1945 to 1965. These books are now at Texas A&M University library, which introduced the books into the OCLC online union catalog from Library of Congress catalog cards while updating name entries, series, subject headings, and classification numbers. Publishers, notable authors, and titles in the Gros collection are surveyed, proceeding from power, mechanical and civil engineering, metallurgy and defense (e.g., aerospace and electrical engineering) to Academy of Sciences and popular publications on science and technology. Book title imagery and style are another perspective on the collection.  相似文献

This paper describes the construction of a synonym thesaurus or entry vocabulary for the SUNY Biomedical Communication Network, which will permit the user greater ease of access to the MeSH-indexed material without previously consulting a printed list of indexing terms. In order to discover the actual terminology used by a researcher, words were extracted from titles of articles appearing in Index Medicus, and compared with the subject heading under which they appeared. As well as strict synonyms, grammatical variants were also included. Work is continuing on relating other indexing vocabularies, such as Excerpta Medica and Current Medical Terminology, used in the biomedical world to MeSH terms.  相似文献

Background:Literature searches underlie the foundations of systematic reviews and related review types. Yet, the literature searching component of systematic reviews and related review types is often poorly reported. Guidance for literature search reporting has been diverse and, in many cases, does not offer enough detail to authors who need more specific information about reporting search methods and information sources in a clear, reproducible way. This document presents the PRISMA-S (Preferred Reporting Items for Systematic reviews and Meta-Analyses literature search extension) checklist, and explanation and elaboration.Methods:The checklist was developed using a three-stage Delphi survey process, followed by a consensus conference and public review process.Results:The final checklist includes sixteen reporting items, each of which is detailed with exemplar reporting and rationale.Conclusions:The intent of PRISMA-S is to complement the PRISMA Statement and its extensions by providing a checklist that could be used by interdisciplinary authors, editors, and peer reviewers to verify that each component of a search is completely reported and, therefore, reproducible.  相似文献

Objective

The authors sought to determine whether unexpected gaps existed in Scopus''s author affiliation indexing of publications written by the University of Nebraska Medical Center or Nebraska Medicine (UNMC/NM) authors during 2014.

Methods

First, we compared Scopus affiliation identifier search results to PubMed affiliation keyword search results. Then, we searched Scopus using affiliation keywords (UNMC, etc.) and compared the results to PubMed affiliation keyword and Scopus affiliation identifier searches.

Results

We found that Scopus''s records for approximately 7% of UNMC/NM authors'' publications lacked appropriate UNMC/NM author affiliation identifiers, and many journals'' publishers were supplying incomplete author affiliation information to PubMed.

Conclusions

Institutions relying on Scopus to track their impact should determine whether Scopus''s affiliation identifiers will, in fact, identify all articles published by their authors and investigators.  相似文献

Summary

This article addresses pricing questions raised by the 1996 acquisition of West Publishing Company by The Thomson Corporation by considering what happened to Lawyer's Co-op/Bancroft-Whitney treatise titles transferred to CB-C following the Thomson acquisition of Lawyer's Co-op. Although the sample of titles examined is small, it appears that price increases have been well above increases in the legal publications industry generally, and this suggests the need to monitor West titles carefully.  相似文献

Readers' advisory databases are used by public librarians to assist patrons in finding books based on the facts of the plot, the factors used to describe the appeal of the book, or read titles similar to another book they have read. Librarians depend on these databases to give a complete view of the titles available given these limiters, and may assume that identical searches in each database would give similar results. This study compares search results from four databases to see the extent of crossover within those results, using fact-based searches, appeal factor searches, and read-alike searches.  相似文献

ABSTRACT

Librarians at the Arnold Bernhard Library of Quinnipiac University were concerned with the usage levels of their electronic reference titles. They added the titles to the library's Web page, made individual records in the online catalog, and even established links between an OPAC keyword search and a search through electronic reference titles. It was still felt that the collection was underutilized. In 2007, the Automation Librarian began a project to add one more level of access to these titles—a graphic interface that simulated the process of walking into a reference room and picking out a title. A preliminary version was loaded in the Fall of 2007, and early results indicate that it has found an audience.  相似文献

Zoological medicine furthers the health and well-being of captive and free-ranging wild animals. Effective information retrieval of the zoological medicine literature demands searching multiple databases, conference proceedings, and organization websites using a wide variety of keywords and controlled vocabulary. Veterinarians, residents, students, and the librarians who serve them must have patience for multiple search iterations to capture the majority of the available knowledge. The complexities of thorough literature searches are more difficult for nondomestic animal clinical cases and research reviews as demonstrated by three search requests involving poisonous snakes, a gorilla, and spiders. Expanding and better disseminating the knowledgebase of zoological medicine will make veterinary searching easier.  相似文献

Abstract

Diversity literary awards and other sources were used to create a list of high-quality titles written by and about underrepresented groups. This list was used to assess the diversity and inclusiveness of the library collections of a land-grant university in the Pacific Northwest and compare it to peer institutions. Gaps in the collection and acquisition processes were identified and will be used to improve the processes to increase the number of diverse titles added to the library’s collections.  相似文献

ABSTRACT

Researcher services have proliferated in recent years and numerous free or fee-based sites now promise increased visibility and impact for authors or contributors of publications and other research products. Not all services have the same goals, however, and it can be difficult to know with which services researchers should engage. In this article we establish three categories (author/researcher identification, academic/professional networking, and reference/citation management) and examine nineteen services that fit into those categories.

Column Editor's Note This JLA column posits that academic libraries and their services are dominated by information technologies, and that the success of librarians and professional staff is contingent on their ability to thrive in this technology-rich environment. The column will appear in odd-numbered issues of the journal, and will delve into all aspects of library-related information technologies and knowledge management used to connect users to information resources, including data preparation, discovery, delivery and preservation. Prospective authors are invited to submit articles for this column to the editor at kenning.arlitsch@montana.edu  相似文献
