Historical Context
Google Scholar was introduced by Google in November 2004. The tool was developed to help users access scholarly articles, theses, books, conference papers, preprints, abstracts, technical reports, and other scholarly literature from various academic publishers, professional societies, online repositories, universities, and other web sites.
Types/Categories
Google Scholar covers a wide range of academic content, which can be broadly categorized into:
- Journal Articles - Peer-reviewed and published articles.
- Conference Papers - Research presented at academic conferences.
- Theses and Dissertations - Graduate and doctoral research works.
- Books and Monographs - Full texts of academic and scholarly books.
- Technical Reports - Reports from research organizations and academic institutions.
- Citations - References in scholarly works.
Key Events
- 2004: Google Scholar is launched.
- 2006: The introduction of My Citations, enabling authors to track citations of their works.
- 2012: Google Scholar Metrics introduced to measure the visibility and influence of recent articles in scholarly publications.
Detailed Explanations
Google Scholar indexes the full text or metadata of scholarly literature from a variety of publishing formats and disciplines. It uses Google’s web-crawling capabilities to provide a comprehensive and unified search experience for academic material. The search results in Google Scholar are ranked by relevance, which is determined by factors such as the full text of each article, the author, the publication in which the article appears, and how often the piece has been cited in other scholarly literature.
Google Scholar Citations
This feature allows researchers to create a personal profile showing their works, citations, h-index, and i10-index. The h-index measures both the productivity and citation impact of the publications, while the i10-index indicates the number of publications with at least ten citations.
Mathematical Formulas/Models
h-index Calculation
The h-index is calculated based on the set of a scientist’s most cited papers and the number of citations that they have received in other publications. The formula for the h-index (h) is:
