searching for information on toxicological data of chemical substances in selected Bibliographic Databases selection of essential Databases for toxicological researches
Chemosphere, 1996Co-Authors: H Ludl, K Schope, I MangelsdorfAbstract:By using information from printed and online database guides, 18 online Bibliographic Databases (BD), which cover literature on toxicology were selected from 5 hosts. A search for literature containing information on three selected chemicals was carried out with each of the Databases, and the number of documents relevant to toxicology found in them was compared by computer-assisted analysis. Some Databases yielded very little information pertinent to toxicology, while others provided a considerable amount. In addition, the Databases contained numerous duplicates (references common to more than one database). Most of the relevant documents could be obtained using only 8 of the 18 BDs selected. These Databases are: Biosis Previews (BIOSIS), Chemical Abstracts (CA), Chemical Safety Newsbase (CSNB), Excerpta Medica (EMBASE), National Institute for Occupational Safety and Health (NIOSH), Scisearch, Toxicology Information Online (TOXLINE) and the former Toxicology Literature (TOXLIT).

searching for information on chemical substances in selected biomedical Bibliographic Databases
Chemosphere, 1995Co-Authors: H Ludl, K Schope, I MangelsdorfAbstract:A method was developed which allows effective searching for information on chemical substances in Databases. Several searches for chemicals in Bibliographic Databases were carried out to analyse the method of indexing chemical names. The recall rates of documents were compared to evaluate information resources as well as searching strategies. Recall rates of documents searched with the CAS Nos. were compared to those searched with substance name. It turned out that searching for substances is most specific and fastest with CAS Nos. They should always be used whenever possible. However, this is not sufficient in many BDs, making an additional search using chemical names necessary. Specific search options that have to be considered for each database are reported.

visualization and quantitative study in Bibliographic Databases a case in the field of university industry cooperation
Journal of Informetrics, 2015Co-Authors: Feng Feng, Leiyong Zhang, Weiguang WangAbstract:Abstract CiteSpace is a visual document analysis software, by which performances and trends of certain disciplines can be displayed for a given period. Moreover, the evolution of a frontier research can be explored by such software as well. This research focuses on the visualization and quantitative study in Bibliographic Databases by taking the university–industry collaboration studies as an example. Using the Web of Science (WOS), 587 publications and over 30,000 references were selected for analysis, which produced the following results: (1) Our method can clearly reveal the key elements of certain disciplines, such as the largest share of publications, the most frequently cited authors and journals in the university–industry cooperation research field; (2) The relationships among the frequently cited authors, references, journals and keywords can be explained visually in the university–industry cooperation research field; (3) Of special note is that the potential problems and evolutionary trends of certain research fields such as university–industry cooperation can also be ascertained via our method; (4) In general, according to the case study, our visualization and quantitative method evolved a new research framework to evaluate the performance of some research areas.

citespace ii visualization and knowledge discovery in Bibliographic Databases
American Medical Informatics Association Annual Symposium, 2005Co-Authors: Marie Synnestvedt, Chaomei Chen, John H HolmesAbstract:This article presents a description and case study of CiteSpace II, a Java application which supports visual exploration with knowledge discovery in Bibliographic Databases. Highly cited and pivotal documents, areas of specialization within a knowledge domain, and emergence of research topics are visually mapped through a progressive knowledge domain visualization approach to detecting and visualizing trends and patterns in scientific literature. The test case in this study is progressive knowledge domain visualization of the field of medical informatics. Datasets based on publications from twelve journals in the medical informatics field covering the time period from 1964-2004 were extracted from PubMed and Web of Science (WOS) and developed as testbeds for evaluation of the CiteSpace system. Two resulting document-term co-citation and MeSH term co-occurrence visualizations are qualitatively evaluated for identification of pivotal documents, areas of specialization, and research trends. Practical applications in bio-medical research settings are discussed.
