Bibliometrics

Bibliometrics involves the quantitative study of academic publications, and measures, among other things, productivity and impact. Collaboration and citations can also be used to illustrate networking and subject interactions.

Bibliometric analyses are often used as a complement to peer review with internal or external evaluations of academic research, for example with ranking of universities and colleges.
 

Bibliometrics at LiU

At LiU, the bibliometrics group is part of the Department for Publishing Infrastructure at the university library. The group supports LiU in a range of ways:

  • Deliver publishing statistics including bibliometric analyses of the departments, subdepartments and research groups at LiU
  • Provide university management with the expertise to evaluate external bibliometric analyses and ranking lists.
  • Raise awareness and knowledge of bibliometrics and its implications within LiU.

In our work with bibliometric analyses we apply the principles in Leiden Manifesto for Research Metrics.

Frequently asked questions

In Thomson Reuter's database Journal Citation Reports ® you can find the journal’s impact factor. Choose between the Science Edition and the Social Sciences Edition, and search for a specific journal or a group of journals in a specific subject category.

There are three citation databases available:

  1. Web of Science is the most widely used database for citation analyses. Indexes ca 12 000 journals as well as conference series and book series. Very good coverage of science and medicine. Good coverage of technology, mathematics and economics. Lower coverage of other social sciences and humanities.

  2. Scopus indexes ca 20 000 journals as well as conference series and book series. Very good coverage of science and medicine. Good coverage of technology, mathematics and economics. Lower coverage of other social sciences and humanities.

  3. Google Scholar is freely available. Indexes all document types – journals, conference proceedings, books, theses, preprints etc. Better coverage of non-english material than Web of Science and Scopus. Specially useful for fields not fully covered by Web of Science and Scopus.

When you want to know your h-index, you have to start by finding your publications in a citation database, i.e., Web of Science, Scopus or Google Scholar. The h-index is usually different depending on what database you use. They cover different sources and the number of citations are not the same.

Web of Science

  1. Search for your name in the Author field (or search by your ORCID/ResearcherID) Search interface in Web of Science
  2. When your publications are listed, choose ”Create Citation Report” Create ciation report in Web of Science
  3. Citation Report gives you the h-index:
    H-index in the citation report in Web of Science

Scopus

  1. Search for your name in the Author field (or by your ORCID) Search interface in Scopus
  2. When your publications are listed, mark them and choose ”View Citation Overview” Show citation report in Scopus
  3. Citation Overview gives you the h-index H-index in citation report in Scopus

Google Scholar

There are two tools available for getting citation metrics based on Google Scholar-publications:

  1. Use Google Scholar Citations - you can create a profile (private or public) and add your publications, and then your citation metrics are computed and presented.
  2. Download Publish or Perish – a software programme that retrieves and analyzes academic citations. It uses Google Scholar to obtain raw citations. Search by Author’s name to see your metrics. H-index in Publish or Perish

A long-standing problem for researchers as they have progressed through their careers is ensuring that their various activities (publications, grants, employment record…) are coupled to themselves; this has been particularly problematic for those with “common” names who have changed affiliation a number of times.

By using a unique identifier such as ORCID and ResearcherID one can make sure all publications are coupled to the correct author.

ORCID

ORCID (Open Researcher and Contributor ID) is a global register where researchers get a unique identifier for use in most aspects of their professional activity. Many journals already make use of these IDs as are the larger international funders. In Sweden, Vetenskapsrådet and the other larger funders are in the process of building up an application system based on ORCID. At LiU, ORCID can be included with publications registered in DiVA and behind the scenes, we have the tools to couple your ORCID to all of your registered publications (i.e. retroactively). 

We recommend that LiU-researchers register themselves at ORCID to get an ID and then send that to E-press.

How to get an ORCID:

  1. Go to http://orcid.org/
  2. Click on “Register now” (direct link: https://orcid.org/register). Enter your name and e-mail address
  3. Send us your ORCID (a 16-digit number, often presented as a link: e.g.: http://orcid.org/0000-0002-3993-9985) to ep@ep.liu.se, together with your LiU-ID. We will then see to that your ORCID is added to all your DiVA posts.
  4. Start using your ORCID when submitting articles to journals and in grant applications.

ResearcherID

ResearcherID is a register developed by Thomson Reuters for the database Web of Science (WoS). Researchers sign up for a ResearcherID, and can then link all their WoS-publications to this ID. This makes it easier to retrieve all publications by a researcher, and it will help avoid the problem of author misidentification.

How to get a ResearcherID:

  1. Go to http://researcherid.com>
  2. Click on the box ”Join now” and fill out your name and e-mail. Follow instructions to complete the registration.
  3. You are able to link your ResearcherID to your ORCID (which you create at the same time if you have not already got one) . We recommend that you do this, so that the two systems can share information. When an article with an ORCID is published, it will automatically be linked to the corresponding ResearcherID.

In the database Norwegian register of scientific journals, series and publishers all publication channels included in the Norwegian model are listed. Search for a journal or publisher to find out if it is a scientific channel (level 1) or a scientific channel considered leading in its field (level 2).

If you want a list of journals in a subject area, you can use Advanced search and specify the Subject Area you are interested in

Altmetrics, or alternative metrics, is an alternative way to measure the impact of a publication rather than traditional citations. You could, for example, measure the number of views on a webpage or the number of blogs or Tweets that mention the publication. This is often done by use of the publication’s DOI (Digital object identifier).

Today, many publications are published online and the use of social media is increasing also in the academic community. This leads to increased opportunities for spreading research results. Publications are also discovered and commented more quickly by others. While traditional citations takes months or years to occur, social media mentions can happen within hours or days. Social media is also available for comments from the public.

Several journals today, for example Nature and PLoS, have altmetric indicators on their article websites, such as the number of downloads of the publication or the number of Tweets about it. Some companies have specialized in gathering information about social media, news media and web based reference systems for a large number of publications. Some of these are Altmetric, Impactstory and Plum Analytics.

LiU E-press has access to data from Altmetric which is used to show the articles from Linköping University with high activity in social media in the last three months.

  1. Think about where you publish. Pick a publication channel that is suitable for your audience but also one which many can access and is considered highly ranked for that audience. Read more about choosing a publication channel on the page Evaluate journals
  2. Parallel publish whenever possible. If you parallel publish your publication more people will have access to it which increases the chance of someone using it. Read more about parallel publishing and other forms of open access on the page Publish Open Access
  3. Active dissemination of your publications. After publication you can use social media and networks for researchers for marketing your publications in order to increase their visibility. Read more about how to use social media as a researcher on the page Social media for researchers
