Citation Analysis

Citation analysis, also known as bibliometrics, is becoming increasingly important for research evaluation and the meaurement of research impact. The Library subscribes to tools to assist with these measurements which are useful for NRF ratings, CV's, interviews, evaluations, etc.

Citation reports

The following are examples of citation reports which are available on request from the Library:

Author analysis: Number of citations, H-index, highest cited articles by author.
Article analysis: Number of times an article has been cited, article level metrics (altmetrics).
Journal analysis: Journal Impact Factor; SJR (SCImago Journal Rank); SNIP (Source Normalized Impact per Paper).
Faculty or department analysis: Summary of citation performance per faculty, department or research group.

Citation reports are available on request from your Faculty Librarian.

Research publication metrics (Definitions, sources for metrics)

Article metrics

The number of citations to articles and books provides a measurable indicator of an individual's impact, providing a measure of how often their work is used by other researchers. Citation counts can be found in the following databases:

Web of Science

A large citation database that only reports the impact of those items indexed by their database.


Another large citation database, which works similar than Web of Science, but it searches a slightly different group of citations.

Google Scholar

This large free database counts citations from both scholarly and non-scholarly sources.

Author metrics

The h-index was developed by Professor Hirsch in 2005 and designed to be a simple metric with which to quantify the output of an individual researcher. The h-index is only meaningful when compared to others in the same discipline. The three databases mentioned above, Web of Science, Scopus and Google Scholar, can be used to calculate an author's h-index or a research group's h-index.

Journal metrics

The Journal Impact Factor is the most well known journal metric, but there are others as well, which attempt to take into account the variations between subject areas.

Journal Citation Reports (JCR)

This database can help one to get a list of top ranked journals in a specific field or to check an individual journal for its impact and rank.


The Scopus databasie is a good tool to compare journals with the 'Compare sources" option. One can analyse a variety of citation parameters, such as the Source Normalized Impact per Paper (SNIP) and the Scimago Journal Rank (SJR). A new measure, Citescore, was added recently. Search for a journal under "Sources" and view the metrics per journal or use the "Compare sources" option to compare journals.

Google Scholar Metrics

Google Scholar can be used to provide a list of journals by subject area ranked by their H5-index.


Scimago is a free website that uses Scopus data to provide rankings for journals.


Altmetrics (or Alternative metrics) was develeped to complement traditional metrics based on citations within academic publications. Evidence of societal impact will be collected in terms of mentions in social media, news reports, etc. Altmetric badges are now embedded within many sources and you can also download the Altmetrics Bookmarklet for individual use.

Please also see the Library guide Bibliometrics and citation analysis for more detailed information.

Unique Author Identifiers


The most recognized system for administering unique author identifiers is ORCID (Open Researcher & Contributor ID), an initiative that aims to create a central registry of unique author identifiers, including a mechanism to link between different author ID schemes, such as ResearcherID. ORCID is rapidly becoming a universal system. It brings together disparate publication data and interoperate with a wide variety of information systems.

You are invited to create your ORCID iD and connect it with your Stellenbosch University identity.  Please click here. If you already have an ORCID iD, please sign in to your account from the button below and connect your iD with your SU identity.

What is ORCID?

Open Researcher and Contributor ID (ORCID) is a non-profit organisation funded by institutional memberships, grant-making organisations and wide variety of research organisations and publishers.

ORCID is a persistent, unique, numeric identifier for individual researchers and creators. It distinguishes you from researchers and creators with the same or similar names.ORCID is similar to ResearcherID, Scopus Author ID, ISNI and other systems for identifying and distinguishing researchers and creators, but ORCID is rapidly becoming a universal system. It brings together disparate publication data and interoperate with a wide variety of information systems.

Please read more about the benefits of using ORCID on the Library guide for ORCID and other researcher identifiers.

Other author/researcher identifiers:
  • Researcher ID
  • Scopus Author ID
  • Google Scholar ID
Please see more information on these researcher identifiers on the library guide on ORCID and other researcher identifiers.

Improving Impact by Online Visibility

It is important for researchers to control their own online presence. What will one find when one enter your name into Google? What do you want them to find? See below some advice on improving your online visibility, in order that others will find the information you want them to find and also to improve your citations.

Institutional and open repositories

Self-archive your research publications in Stellenbosch University's institutional repository SUNScholar (if the publisher allows it) and other subject repositories such as arXiv.org or SSRN. This will help make your research discoverable, your citations might increase and Google will track when you have been cited.

Professional networking sites

Your LinkedIn profile may be the top item on a Google search using your name, therefore it is important to make sure that the information on your profile is accurate and up to date.

Profiles focusing on your research products

The following products focus specifically on your research. Creating and maintaining your profile on these sites will make others aware of your research and help you see the impact of your work on the research community: ORCID, Kudos, figshare, ImpactStory.

Social media

Twitter is very popular among researchers as a place to share recent publications, opinions about research on your topic and many more. A Facebook profile may also be used to share information about your research.

Academic networking sites for researchers

ResearchGate, academia.edu and Mendeley are examples of academic networking sites for researchers. You can discover new research on your topic (sometimes even including full text articles), find collaborators and update your online profile. Your profiles will show when someone searches your name on Google.

Research Group websites

It is helpful to have and maintain a detailed research group or departmental website. It is important to update it regularly with your recent publications and research interests. You may also consider to start a research group blog where you can share any content about your research group or their work.

Sitaatanalise, ook bekend as bibliometrie, word al meer belangrik vir navorsingsevaluering en die meting van navorsingsimpak. Die Biblioteek teken in op databasisse wat van hulp is met hierdie metings, wat nuttig is vir NRF evaluerings, CV's, onderhoude, evaluerings, ens.


Die volgende is voorbeelde van sitaatverslae wat op aanvraag van die Biblioteek :

Outeursanalise: Aantal sitasies, h-indeks, artikels wat die meeste aangehaal is
Artikelanalise: Aantal kere wat 'n artikel aangehaal is, altmetrics (article level metrics)
Tydskrifanalise: Journal Impact Factor; SJR (SCImago Journal Rank); SNIP (Source Normalized Impact per Paper)
Analise per fakulteit of departement: Opsomming van sitaatprestasie per fakulteit, departement of navorsingsgroep

Sitaatverslae is beskikbaar op aanvraag van jou Fakulteitsbibliotekaris.


Die aantal sitasies vir artikels en boeke verskaf 'n meetbare indikator van 'n individu se impak, sowel as 'n meting van hoe gereeld die individu se werk deur ander navorsers  gebruik word. Sitaatmetings kan in die volgende databasisse gevind word:

Web of Science

'n Groot sitaatdatabasis wat slegs verslag doen oor die impak van items wat in hul databasis geïndekseer word.


Nog 'n groot sitaatdatabasis soortgelyk aan Web of Science, maar wat 'n effens verskillende groep sitasies indekseer.

Google Scholar

Hierdie groot gratis databasis meet sitasies van vakkundige sowel as nie-vakkundige bronne.


Die h-indeks is in 2005 deur Professor Hirsch ontwikkel  en ontwerp om 'n eenvoudige meting te wees wat die uitset van 'n individuele navorser kwantifiseer. Die h-indeks het slegs waarde wanneer dit met ander in dieselfde dissipline vergelyk word. Die drie databasisse wat hierbo genoem word, Web of Science, Scopus en Google Scholar, kan gebruik word om 'n outeur of 'n navorsingsgroep se h-indeks te bepaal.


Die Journal Impact Factor is die bekendste tydskrifmeting, maar daar is ook ander wat poog om die verskille per onderwerpsgebied in ag te neem.

Journal Citation Reports (JCR)
Hierdie databasis word gebruik om 'n ranglys van tydskrifte in 'n spesifieke onderwerpsveld te bekom of om 'n individuele tydskrif se impak of rangorde na te gaan.

Se hulpmiddel, Compare Journals,  is nuttig om te gebruik vir die analise van 'n verskeidenheid sitaatparameters, soos die impak per publikasie (IPP) en Source Normalized Impact per Paper (SNIP).

Google Scholar Metrics
Word gebruik om 'n lys tydskrifte per onderwerpsveld te trek wat volgens hul H5-indeks gerangskik is.

Scimago is 'n gratis databasis wat gebaseer is op Scopus data om ranglyste vir tydskrifte te skep.


Altmetrics (of alternatiewe metings) is ontwikkel om tradisionele metings wat op sitasies van akademiese publikasies gebaseer is, aan te vul. Bewys van sosiale impak word versamel in terme van hoeveel keer in sosiale media na die artikel verwys word, nuusverslae, ens. Altmetric inligting word nou vasgelê in verskeie bronne en dit is ook moontlik om die Altmetrics Bookmarklet af te laai vir individuele gebruik.

Sien ook asseblief die biblioteekgids Bibliometrics and citation analysis vir meer inligting.

Unieke Navorsersidentiteite
Die stelsel wat die meeste erken word vir die skep van 'n unieke navorsersidentiteit is ORCID (Open Researcher & Contributor ID), 'n inisiatief wat daarop gerig is om 'n sentrale register van unieke outeursidentiteite te skep, met insluiting van metodes om tussen verskillende outeur IDs, bv. ResearcherID, te skakel. ORCID is vinnig  besig om 'n universele stelsel te word wat verskeie publikasiedata bymekaarbring en met 'n wye verskeidenheid inligtingstelsels integreer.

Skep jou ORCID iD en koppel dit met jou Universiteit Stellenbosch identiteit hier. Indien jy reeds 'n ORCID iD het, teken in en koppel jou iD met jou US identiteit.

Wat is ORCID?
Open Researcher en Contributor ID (ORCID) is 'n organisasie wat befonds word deur institusionele lidmaatskap, befondsingorganisasies en 'n wye verskeidenheid navorsingsorganisasies en uitgewers.

ORCID bied 'n unieke, numeriese identifiseerder vir individuele navorsers en outeurs. Dit onderskei jou van navorsers met dieselfde of soortgelyke naam. ORCID is soortgelyk aan ResearcherID, Scopus Author ID, ISNI en ander stelsels wat navorsers identifiseer en van mekaar onderskei. ORCID groei vinnig en is besig om 'n universele stelsel te word. Dit bring ook 'n verskeidenheid publikasiedata bymekaar en integreer met verskillende inligtingstelsels.

Lees asseblief meer oor die voordele van die gebruik van ORCID in die Biblioteekgids ORCID and other researcher identifiers.

Ander outeur/navorsersidentifiseerders:
  • ResearcherID
  • Scopus Author ID
  • Google Scholar ID
Sien asseblief meer inligting oor hierdie navorsersidentifiseerders in die biblioteekgids ORCID and other researcher identifiers.

Verbeter Jou Sigbaarheid as Navorser

Dit is vir navorsers belangrik om hul teenwoordigheid op die internet te beheer. Wat sal iemand vind as hulle jou naam op Google invoer? Wat wil jy hê moet gevind word? Hieronder volg raad oor hoe om jou sigbaarheid te verbeter sodat ander die inligting oor jou sal vind wat jy graag wil hê gevind moet word en ook om jou aantal sitate te verbeter.

Institusionele en oop navorsingsbewaarplekke

Argiveer self jou navorsingspublikasies in Universiteit Stellenbosch se institusionele bewaarplek SUNScholar (indien die uitgewer dit toelaat)  en ander onderwerpsbewaarplekke soos arXiv.org of SSRN. Dit sal help om jou navorsing meer opspoorbaar te maak, jou sitasies kan meer raak en Google sal naspoor wanneer 'n ander navorser jou aangehaal het.

Professionele netwerkwebblaaie

Jou LinkedIn profiel is gewoonlik die eerste item in 'n Google lys van resultate wanneer jou naam as soekterm gebruik word. Daarom is dit belangrik om te verseker dat die inligting op jou profiel korrek en op datum is. 

Profiele wat fokus op jou navorsingsuitsette

Die volgende produkte fokus spesifiek op navorsing. Indien jy 'n profiel hier skep en in stand hou, maak jy ander navorsers meer bewus van jou navorsing en kan jy die impak van jou werk op die navorsingsgemeenskap sien: ORCID, Kudos, figshare, ImpactStory.

Sosiale media

Twitter is baie gewild by navorsers om nuwe publikasies, opinies oor spesifieke navorsing  en nog meer te deel. 'n Facebook​ profiel kan ook gebruik word om inligting oor jou navorsing te deel.

Akademiese netwerkwebblaaie vir navorsers

ResearchGate, academia.edu en Mendeley is voorbeelde van akademiese netwerkwebblaaie vir navorsers. Dit is moontlik om hiermee nuwe navorsing oor jou onderwerp op te spoor (insluitend soms volteksartikels) sowel as nuwe medewerkers. Jou profiel sal verskyn wanneer iemand jou naam op Google invoer.

Webblaaie vir navorsingsgroepe

Dit is nuttig om 'n gedetailleerde webblad vir 'n navorsingsgroep of departement te hê, maar belangrik dat dit gereeld opgedateer word met jou onlangse publikasies en navorsingsonderwerpe. Dit mag ook nuttig wees om 'n blog vir jou navorsingsgroep te begin waar jy enige inligting oor jou navorsingsgroep en hul navorsing kan deel.
