Research Impact

Research impact is generally the effect of research on society, economy, and culture outside of academia. Despite the difficulty of accurately measuring research impact in a broader context, some quantitative measurements based on citation metrics are commonly used by academia as an indicator of the impact of research.

Citation metrics are useful to researchers for identifying key publications and authors. Also, these metrics can be used to track the impact of articles, journals, and authors.

Article Impact

Usually, an article's impact is measured by how many times it has been cited.

Scopus article metrics

Four metrics can be found on a document’s metrics details page: 

  • total number of citations by a date range of the user’s choosing, 
  • citations per year for a range,
  • citation benchmarking (percentile),
  • Field-weighted Citation Impact.

Views count has been added so users can understand usage at a glance.

Preprints from some preprint servers (including SSRN) have been indexed in Scopus. However, preprints are considered a separate publication type from other curated published content and they do not contribute to any metrics available in Scopus. You can read more about preprints here.

Google Scholar publication metrics

Google Scholar includes journal and conference papers, theses and dissertations, academic books, pre-prints, abstracts, technical reports and other scholarly literature from all broad areas of research. Google Scholar also includes court opinions and patents. Due to the variety of indexed publication types the number of citations can be different from Scopus and Web of Science.

Metrics include:

  • Cited by
  • Web of Science citations count

Journal Impact

Journal metrics show the scientific impact of a journal and help to choose the best scientific journal for publication.

Scopus Journal Metrics

Scopus source metrics allow you to directly compare sources, regardless of their subject classification. 

To view source metrics:

  • select Sources in the top navigation bar and search for a source title, subject area or ISSN number,
  • search for a source title using documents search and click on the source title in the Source column in the results.

Source metrics are shown on the source details page. A source details page lists basic source information and journal metric scores for Scopus journals, book series, conference proceedings, and trade publications.

Source details page metrics include:

The source details page shows quartile and percentile rankings by Citescore.

Web of Science Journal Metrics

Journal metrics are available in the Journal Citation Reports. The link to the Journal Citation Reports is in the Products menu on the Web of Science webpage. To find a specific title and view its profile, use the full search bar for journal name, ISSN, eISSN, category or keyword. Each journal covered in the Journal Citation Reports has a Journal Profile page that provides access to detailed information about the journal, data, metrics and content.

Journal Profile page metrics include:

  • Journal Impact Factor (JIF)
  • Rank by Journal Impact Factor (journal quartile, percentile rankings)
  • Journal Citation Indicator (JCI)
  • Rank by Journal Citation Indicator (journal quartile, percentile rankings)

Google Scholar Top Publications

Google Scholar Metrics provide an easy way for authors to quickly gauge the visibility and influence of recent articles in scholarly publications. Scholar Metrics summarize recent citations to many publications, to help authors as they consider where to publish their new research.

Publications metrics include:

  • h5-index is the h-index for articles published in the last 5 complete years. It is the largest number h such that h articles published in 2018-2022 have at least h citations each.
  • h5-median for a publication is the median number of citations for the articles that make up its h5-index.

SCIMAGO Journal Ranks

The SCImago Journal & Country Rank is a publicly available portal that includes the journals and country scientific indicators developed from the information contained in the Scopus database. This platform takes its name from the SCImago Journal Rank (SJR) indicator, developed by SCImago. SCImago Journal Rank (SJR) indicator is also visible in Scopus and SciVal.

Journals can be searched by journal title, ISSN or publisher. Journal sets listed in rankings can be customized by filtering and ranking criteria and applying a lower threshold to the ranking.

Every journal has a a profile page including time series tables and charts to analyze significative metrics of journal performance. Journal profile metrics include: H Index, Quartiles, SJR, Citations per document (4, 3 and 2 years), Total Cites, Self-Cites, External Cites per Document, Cites per Document, International Collaboration, Citable Documents, Non-Citable Documents, Cites Documents, Uncited Documents.

Author Impact

Publication data inform funding and promotion applications. It is also used by those assessing the output of researchers and institutions. So, it is critical that each author's profile data is up-to-date and accurate. Author profiles help tell a more accurate and complete story about the output and influence of researchers and institutions compared to other solutions.

Scopus Author Metrics

Author metrics are displayed on the Author details page. The Author details page provides information about author research areas, publishing and citation information, name variants, the author Scopus identifier number, ORCID (if available), and other information regarding author publication history.

On the Author details page you can see:

  • citations
  • the document & citations trends graph
  • h-index

The Analyze author output page provides a visual graph of document, h-index, citations, co-author information, and other functions.

The citation overview displays the documents for an author details page and includes the number of times the documents were cited by publication year. You can view, print, or export a list of the citing documents. 

The link View all metrics takes you to the Author Metrics tab. The Author Metrics tab shows:

SciVal Author Metrics

SciVal researcher metrics are automatically generated based upon the researcher's Scopus Author Profile. The metrics given for a researcher or author in SciVal may look different to those found in Scopus for several reasons:

  • the year range you are looking at in SciVal is not the same as in Scopus,
  • there is a small time lag between Scopus and SciVal (SciVal is typically 1-2 weeks behind Scopus),
  • author profile corrections.

Metrics in SciVal include:

Web of Science Author Metrics

Use Researcher Search to search for author records and profiles of researchers across the Web of Science Core Collection. Researcher Search helps identify articles likely authored by the same person and view profiles for those authors that contain metrics and other scholarly activity (for example, peer review).

Author metrics are displayed in the author record. An author record is a set of documents likely authored by the same person. An author’s documents may show up on multiple records, or a record may have a document incorrectly assigned to it. An author can claim an author record to create a Web of Science Researcher Profile. 

Claim My Record can be used to claim publications authored by the same author in the Web of Science. This ensures your author record lists only publications you authored. Researchers can claim author records that have not already been claimed by someone else, or add publications in an author record to an existing claimed researcher profile.

It is also possible to create a Web of Science ResearcherID. It is a unique identifier that differentiates researchers in the Web of Science. Having a ResearcherID does not mean that the author record has been claimed by the researcher. 

It is possible to connect your ORCID account to your profile and then turn on settings which allow you to easily keep both your ORCID and Web of Science researcher profile up to date and in sync.

On the right-hand side of your Web of Science researcher profile, you will see a metrics sidebar once you have populated your profile by adding some publications, reviews or editor records.

Data corrections in Scopus and Web of Science

Correcting data is important because the scientific data helps to associate a researcher's publications with the researcher's profiles and contributes to the author metrics displayed in them (h-index, citations). Scopus and Web of Science data is used by funding agencies, institutions and other researchers to assess research and impact.

The data in Scopus and Web of Science is gathered from indexed publications. Errors mostly occur when the publication itself contains incorrect information. The most common errors are using different forms of the author's name and using the wrong form of the university name (TalTech). Grammatical errors also introduce new authors and institutions into the databases.

In Scopus and Web of Sciene, it is possible to correct data using correction submission forms. It is important to check whether the error is caused by Scopus or Web of Science or whether the error is in the original publication. Scopus and Web of Science only correct their own errors. If the error has come from a publication, you must contact the publisher of the publication.

For example, it is possible to correct errors in the title of the article, the affiliation with the university, and the names of the authors through the forms.
