1. Citation Index as a General Concept:
This refers to the number of times a particular piece of work (e.g., a research paper, a book, a patent) has been cited by other publications. This is a crucial metric in academia and research because it reflects the impact and influence of that work. A high citation index generally indicates that the work is considered important, relevant, and influential within its field.
2. Specific Citation Indexes as Databases:
There are several well-known databases that collect and analyze citations. Some of the most prominent ones include:
* Web of Science (WoS): Developed by Clarivate Analytics, WoS is a comprehensive database that indexes millions of publications across various disciplines, including science, technology, social sciences, and humanities. It's particularly known for its Impact Factor metric, which measures the average number of citations received by articles in a specific journal.
* Scopus: Created by Elsevier, Scopus is another large-scale database that indexes research literature. It offers a variety of features, including citation tracking, analysis tools, and collaboration networks.
* Google Scholar: Google Scholar is a free, publicly accessible search engine that indexes scholarly literature from various sources. While not as comprehensive as WoS or Scopus, it offers a user-friendly interface and vast coverage.
3. "Citation Index" as a Part of a Publication:
Some journals and publications include a citation index at the end of each article. This list provides a comprehensive overview of all the works that the author has cited in their research.
Key Points to Remember:
* Citation indices are important indicators of research impact and influence.
* Different databases use different methodologies and coverage, so it's crucial to consider the context and limitations of each database when interpreting citation data.
* Citation indices are just one of many metrics that can be used to evaluate research quality.
