Google Scholar Metrics - Short Review

Research Tools



Product Overview: Google Scholar Metrics

Google Scholar Metrics is a powerful tool designed to help authors, researchers, and academics gauge the visibility, influence, and impact of scholarly publications. Here’s a detailed look at what the product does and its key features and functionality.



Purpose and Functionality

Google Scholar Metrics provides a comprehensive way to measure the impact of journal articles and publications through citation analysis. This tool helps authors assess the influence of recent articles, identify highly cited publications, and make informed decisions about where to publish their new research.



Key Features



Citation Metrics

  • h-index: This metric measures the largest number \(h\) such that at least \(h\) articles in a publication have been cited at least \(h\) times each. For example, if a publication has five articles cited by 17, 9, 6, 3, and 2 times respectively, its h-index would be 3.
  • h-core: This refers to the set of top-cited \(h\) articles from the publication, which the h-index is based on. For instance, the h-core for the previous example would include the three articles cited 17, 9, and 6 times.
  • h-median: This is the median of the citation counts within the h-core, providing a central measure of the distribution of citations to the articles in the h-core. In the example, the h-median would be 9.


Five-Year Metrics

  • h5-index: A variation of the h-index that focuses only on articles published in the last five years. This ensures that a journal’s impact is measured in a more recent context.
  • h5-median: The median citation count of the articles in the h5-core, similar to the h-median but limited to the last five years.


Browsing and Exploration

  • Users can browse the top 100 publications in several languages, ordered by their five-year h-index and h-median metrics. This allows for a quick overview of the most influential publications in various fields.
  • The tool enables users to explore publications in broad research areas (e.g., Engineering & Computer Science, Health & Medical Sciences) and specific subcategories (e.g., Databases & Information Systems, Development Economics). However, browsing by research area is currently available only for English publications.


Author Profiles and Tracking

  • Authors can set up their profiles on Google Scholar to track who is citing their publications and view their citation metrics. This includes adding articles manually and seeing articles that match their name as the author.
  • The profile section includes a total number of citations to the author’s publications and metrics like the h-index and i10-index (the number of publications with at least 10 citations).


Coverage and Inclusions

  • Google Scholar Metrics cover a substantial fraction of scholarly articles published in the last five years, excluding items like court opinions, patents, books, dissertations, and publications that received no citations in the last five years. Only publications with at least a hundred articles in the last five years are included.


Benefits

  • Informed Publishing Decisions: Helps authors choose where to publish their new research by providing insights into the citation impact of various journals.
  • Visibility and Influence: Allows authors to gauge the visibility and influence of their recent articles and recognize which journals are most cited.
  • Comprehensive Metrics: Offers a broader scope of academic publications, including niche fields that may not be well-represented in other databases.

In summary, Google Scholar Metrics is an indispensable tool for the academic community, providing detailed citation metrics and facilitating informed decisions about research publication and citation tracking.
