This paper describes the features of the problem-thematic structure of the Science Studies Database, which was created at the Institute of Scientific Information on Social Sciences (INION) of the Russian Academy of Sciences. A complex of linguistic tools for science studies, which was developed for analytical and synthetic processing of documents and queries, is described. The features of the formation of information search strategies are considered.  相似文献

CRISP (Computer Retrieval of Information on Scientific Projects) is a large database maintained and operated by the National Institutes of Health (NIH). It contains comprehensive scientific and selected administrative data on research carried out by the U.S. Public Health Service (PHS) or supported by PHS grants and contracts. Developed originally to meet the needs of NIH, it is an excellent, largely untapped resource for health information professionals at large, revealing new trends, methods, and techniques, often before they appear in the published literature. CRISP uses its own controlled vocabulary, developed to permit indexing of new and active research areas. Queries can combine subject headings with a great variety of administrative data elements (e.g., research category or principal investigator's name). Output is available in a variety of formats and media. While information professionals cannot directly access the CRISP system, abridged CRISP records are merged into the FEDRIP (Federal Research in Progress) database, and FEDRIP is publicly accessible through DIALOG. CRISP records in toxicology are also furnished to the National Library of Medicine's TOXLINE database. This paper discusses the indexing, information retrieval, publication products, and search services of the CRISP system, and how users of medical information can benefit from it.  相似文献

This article describes how the National Science Foundation's support of information research has evolved from NSF's original mission of improving the dissemination of scientific and technical information to its present interest in information robotics and intelligent systems. The pattern of grant support, since a major reorganization of the information science division in 1978, is analyzed in terms of the institutions, the investigators, and the disciplines that have been major grant recipients.  相似文献

This paper presents a review of open data research based on bibliometric analysis of publications in Web of Science from 1998 to 2016. It shows that research on open data has grown rapidly since 2009 with the development of various open data initiatives. We identify the different themes using science mapping and performance analysis. The most important themes are semantic web, open government, and crowdsourcing. The basic and transversal themes are data sharing and public sector information. As for the emerging themes, these are Big Data and open government data. In addition, data journalism, monitoring, and recommender systems are specific themes that deserve special attention. The UK and the USA are the leading publishing countries, both in theoretical and practical research on open data. In China, most researchers focus on practical research, and there have been efforts to promote the development of open data. Papers introducing large‐scale projects receive more attention and citation quickly. Recently, researchers have been publishing more on objective topics, including possible issues and dilemmas in the era of Big Data and many problems such as budgets, ownership, licensing, culture, and sustainable development.  相似文献

Background: Academic, medical and research libraries frequently implement Web 2.0 services for users. Several reports notwithstanding, characteristics and effectiveness of services are unclear. Objectives: To find out: the Web 2.0 services implemented by medical, academic and research libraries; study designs, measures and types of data used in included articles to evaluate effectiveness; whether the identified body of literature is amenable to a systematic review of results. Methods: Scoping review mapping the literature on the topic. Searches were performed in 19 databases. Inclusion criteria: research articles in English, Italian, German, French and Spanish (publication date ≥2006) about Web 2.0 services for final users implemented by academic, medical and research libraries. Reviewers’ agreement was measured by Cohen’s kappa. From a data set of 6461 articles, 255 (4%) were coded and analysed. Results: Conferencing/chat/instant messaging, blogging, podcasts, social networking, wikis and aggregators were frequently examined. Services were mainly targeted at general academic users of English‐speaking countries. Conclusions: Data prohibit a reliable estimate of the relative frequency of implemented Web 2.0 services. Case studies were the prevalent design. Most articles evaluated different outcomes using diverse assessment methodologies. A systematic review is recommended to assess the effectiveness of such services.  相似文献

Objectives: What does the publicly available literature tell us about the attitudes of health care staff to the development of information technology in practice, including the factors which influence them and the factors which may be used to change these attitudes? Methods: Twelve databases were searched for literature published between 2000 and 2005 that identified research related to information technology (IT), health professionals and attitude. English language studies were included which described primary research relating to the attitudes of one or more health care staff groups towards IT. Letters, personal viewpoints, reflections and opinion pieces were not included. Results: Complex factors contribute to the formation of attitudes towards IT. Many of the issues identified were around the flexibility of the systems and whether they were ‘fit for purpose’, along with the confidence and experience of the IT users. The literature suggests that attitudes of practitioners are a significant factor in the acceptance and efficiency of use of IT in practice. The literature also suggested that education and training was a factor for encouraging the use of IT systems. Conclusions: A range of key issues, such as the need for flexibility and usability, appropriate education and training and the need for the software to be ‘fit for purpose’, showed that organizations need to plan carefully when proposing the introduction of IT‐based systems into work practices. The studies reviewed did suggest that attitudes of health care professionals can be a significant factor in the acceptance and efficiency of use of IT in practice. Further qualitative and quantitative research is needed into the approaches that have most effect on the attitudes of health care staff towards IT.  相似文献
