A model for enhancing Internet medical document retrieval with "medical core metadata".
(1/419)
OBJECTIVE: Finding documents on the World Wide Web relevant to a specific medical information need can be difficult. The goal of this work is to define a set of document content description tags, or metadata encodings, that can be used to promote disciplined search access to Internet medical documents. DESIGN: The authors based their approach on a proposed metadata standard, the Dublin Core Metadata Element Set, which has recently been submitted to the Internet Engineering Task Force. Their model also incorporates the National Library of Medicine's Medical Subject Headings (MeSH) vocabulary and MEDLINE-type content descriptions. RESULTS: The model defines a medical core metadata set that can be used to describe the metadata for a wide variety of Internet documents. CONCLUSIONS: The authors propose that their medical core metadata set be used to assign metadata to medical documents to facilitate document retrieval by Internet search engines. (+info)
Library residencies and internships as indicators of success: evidence from three programs.
(2/419)
This paper discusses post-master's degree internships in three very different organizations; the University of Illinois at Chicago, the National Library of Medicine, and the Library of Congress. It discusses the internships using several questions. Do the programs serve as a recruitment strategy? Do the programs develop key competencies needed by the participant or organization? Do the programs develop leaders and managers? Is acceptance into a program an indicator of future career success? A survey was mailed to 520 persons who had completed internships in one of the three programs. There was a 49.8% response rate. Responses to fifty-four questions were tabulated and analyzed for each program and for the total group. The results confirm the value of internships to the career of participants. (+info)
Complete genomes in WWW Entrez: data representation and analysis.
(3/419)
MOTIVATION: The large amount of genome sequence data now publicly available can be accessed through the National Center for Biotechnology Information (NCBI) Entrez search and retrieval system, making it possible to explore data of a breadth and scope exceeding traditional flatfile views. RESULTS: Here we report recent improvements for completely sequenced genomes from viruses, bacteria, and yeast. Flexible web based views, precomputed relationships, and immediate access to analytical tools provide scientists with a portal into the new insights to be gained from completed genome sequences. AVAILABILITY: Entrez Genomes can be accessed on the World Wide Web at http://www.ncbi.nlm.nih.gov/Entrez/Genome/ org.html. (+info)
Powerful connections for public health: the National Library of Medicine and the National Network of Libraries of Medicine.
(4/419)
As incorporated in Healthy People 2010 objectives, data and information systems and a skilled workforce are 2 of the critical components of the public health infrastructure. The National Library of Medicine (NLM) and the National Network of Libraries of Medicine (NN/LM) are important resources for improving Internet access and providing related training to the public health workforce and to those in training for public health careers. The NLM and the NN/LM have joined forces with the Centers for Disease Control and Prevention, the Health Resources and Services Administration, the Association of State and Territorial Health Officials, the National Association of County and City Health Officials, and the Public Health Foundation. The goal of this collaboration is to improve electronic resources useful in public health practice and increase awareness of them, to train public health professionals to use electronic information services, and to help public health agencies obtain the equipment and Internet connections needed to use these services effectively. The databases, outreach programs, and connection grants available to public health professionals from the NLM, and the training and ongoing support available from the NN/LM for accessing these programs and services, are described.

Terminology issues in user access to Web-based medical information.
(5/419)
We conducted a study of user queries to the National Library of Medicine Web site over a three month period. Our purpose was to study the nature and scope of these queries in order to understand how to improve users' access to the information they are seeking on our site. The results show that the queries are primarily medical in content (94%), with only a small percentage (5.5%) relating to library services, and with a very small percentage (.5%) not being medically relevant at all. We characterize the data set, and conclude with a discussion of our plans to develop a UMLS-based terminology server to assist NLM Web users. (+info)
IAIMS: an interview with Dick West. Integrated Advanced Information Management Systems. Interview by Joan S Ash and Frances E Johnson.
(6/419)
Richard T. West, IAIMS (Integrated Advanced Information Management Systems) Program Officer at the National Library of Medicine for 13 years, reflects on the origin, development, effectiveness, and future of IAIMS efforts. He dwells on the changes that have taken place as the concept of IAIMS has evolved from a technology-based to an organization-based level of integration. The role of IAIMS in patient care, education, and research is discussed, along with the role of the librarian in the implementation of IAIMS programs. He sees a need for training for librarians, informaticians, and others in preparation for these efforts and for the development of academic reward systems that encourage them. He expresses a desire for those working in information technology in hospitals to gain a clearer understanding of IAIMS, because the concept fits hospitals as well as academic health science centers. He exhorts informaticians to bring to reality the futuristic fantasies of a new information world. (+info)
Database resources of the National Center for Biotechnology Information.
(7/419)
In addition to maintaining the GenBank(R) nucleic acid sequence database, the National Center for Biotechnology Information (NCBI) provides data analysis and retrieval and resources that operate on the data in GenBank and a variety of other biological data made available through NCBI's Web site. NCBI data retrieval resources include Entrez, PubMed, LocusLink and the Taxonomy Browser. Data analysis resources include BLAST, Electronic PCR, OrfFinder, RefSeq, UniGene, Database of Single Nucleotide Polymorphisms (dbSNP), Human Genome Sequencing pages, GeneMap'99, Davis Human-Mouse Homology Map, Cancer Chromosome Aberration Project (CCAP) pages, Entrez Genomes, Clusters of Orthologous Groups (COGs) database, Retroviral Genotyping Tools, Cancer Genome Anatomy Project (CGAP) pages, SAGEmap, Online Mendelian Inheritance in Man (OMIM) and the Molecular Modeling Database (MMDB). Augmenting many of the Web applications are custom implementations of the BLAST program optimized to search specialized data sets. All of the resources can be accessed through the NCBI home page at: http://www.ncbi.nlm.nih. gov (+info)
GenBank.
(8/419)
The GenBank((R))sequence database incorporates publicly available DNA sequences of >55 000 different organisms, primarily through direct submission of sequence data from individual laboratories and large-scale sequencing projects. Most submissions are made using the BankIt (Web) or Sequin programs and accession numbers are assigned by GenBank staff upon receipt. Data exchange with the EMBL Data Library and the DNA Data Bank of Japan helps ensure comprehensive worldwide coverage. GenBank data is accessible through NCBI's integrated retrieval system, Entrez, which integrates data from the major DNA and protein sequence databases along with taxonomy, genome, mapping and protein structure information, plus the biomedical literature via PubMed. Sequence similarity searching is provided by the BLAST family of programs. Complete bimonthly releases and daily updates of the GenBank database are available by FTP. NCBI also offers a wide range of WWW retrieval and analysis services based on GenBank data. The GenBank database and related resources are freely accessible via the NCBI home page at http://www.ncbi.nlm.nih.gov (+info)
