A Practical Guide to Bibliometric Analysis Using VOSviewer

If you’ve ever attempted to write a literature review and were confronted by hundreds of research articles, you are not the only person to have experienced this challenge. Researchers have a particularly hard time finding, recording, and analyzing trends and important emerging topics and authors because of the rapid increase in the volume of academic work being published.

This is where you will find Bibliometric Analysis particularly valuable.

Bibliometric analysis allows researchers to analyze trends in scientific publications and use quantitative methods. Instead of the nearly impossible task of manually reviewing thousands of articles, you will be presented with a visualization of relationships between authors, keywords, journals, institutions, and countries, among others, possibly with the click of a few buttons. One of the most popular of these tools is VOSviewer, which is free software for bibliometric mapping and visualization.

This practical guide will provide you with a bibliometric analysis background, as well as the reasons researchers prefer VOSviewer, and a step by step guide to performing your own analysis.

What Is Bibliometric Analysis?

Bibliometric analysis is a research method used to evaluate and analyze Academic literature through measurable data such as citations, publications, keywords, and collaboration networks.

Researchers commonly use it to:

1. Discover research trends

2. Identify influential papers and authors

3. Analyze collaboration between institutions or countries

4. Explore keyword relationships

5. Map the intellectual structure of a research field

The growing popularity of bibliometric studies is largely due to the availability of databases like Scopus and Web of Science, combined with visualization tools such as VOSviewer and CiteSpace.

In simple terms, bibliometric analysis transforms large volumes of academic data into visual maps that are easier to interpret.

Why Use VOSviewer for Bibliometric Analysis?

Among all bibliometric tools available today, VOSviewer stands out because it is beginner-friendly, lightweight, and highly visual.

According to academic library resources, VOSviewer can create networks based on:

1. Co-authorship

2. Citation analysis

3. Co-citation analysis

4. Bibliographic coupling

5. Keyword co-occurrence

The software is especially popular because it allows researchers to visualize complex relationships using colorful network maps.

Here’s why many researchers prefer VOSviewer:

Easy Visualization

The software automatically creates visual clusters that reveal patterns and relationships in research data.

Free to Use

Unlike many premium academic tools, VOSviewer is freely available for researchers and students.

Supports Major Databases

You can import files from Scopus, Web of Science, PubMed, and other academic databases.

Useful for Beginners

Even researchers with limited technical skills can quickly learn the basics.

Step-by-Step Guide to Bibliometric Analysis Using VOSviewer

Let’s walk through the practical process.

Step 1: Define Your Research Topic

Before collecting data, clearly identify your research question or topic.

For example:

• Artificial Intelligence in Healthcare
• Sustainable Tourism
• Digital Marketing Trends
• Climate Change Adaptation

A focused topic produces cleaner and more meaningful visualizations.

Experts recommend defining clear research objectives before beginning bibliometric studies to avoid irrelevant or noisy datasets.

Step 2: Choose a Reliable Database

The quality of your bibliometric analysis depends heavily on your data source.

The most commonly used databases are:

Scopus

Web of Science

PubMed

Google Scholar

Scopus and Web of Science are often preferred because they provide structured metadata compatible with VOSviewer.

When searching, use targeted keywords related to your topic.

Example:

"Bibliometric Analysis" AND "Artificial Intelligence"

Apply filters such as:

1. Publication years
2. Document type
3. Language
4. Subject area

Step 3: Export the Data

After selecting relevant articles, export the bibliographic data.

For VOSviewer, the recommended export formats are:

CSV (Scopus)

TXT (Web of Science)

RIS files

Be sure to include:

• Citation information
• Abstracts
• Keywords
• References
• Author details

These fields are essential for generating accurate network maps.

Step 4: Clean the Data

Data cleaning is one of the most important steps in bibliometric analysis.

Why?

Because author names, institutions, and keywords are often inconsistent.

For example:

"AI" vs. "Artificial Intelligence"

"Univ Oxford" vs. "University of Oxford"

Cleaning improves visualization accuracy and prevents duplicate entries.

Researchers frequently use Excel, OpenRefine, or R packages for preprocessing and normalization.

Step 5: Import Data into VOSviewer

Now comes the exciting part.

Open VOSviewer and select:

Create a Map Based on Bibliographic Data

Upload your exported file and choose the type of analysis you want.

Popular options include:

Co-Authorship Analysis

Shows collaboration between authors or institutions.

Keyword Co-Occurrence

Identifies trending research themes.

Citation Analysis

Highlights influential publications.

Co-Citation Analysis

Shows which papers are frequently cited together.

Bibliographic Coupling

Connects papers sharing similar references.

Each visualization helps uncover different dimensions of a research field.

Step 6: Interpret the Visualization Maps

This is where bibliometric analysis becomes incredibly valuable.

VOSviewer creates colorful clusters representing relationships between nodes.

Typically:

Larger circles = more influential items

Lines = stronger relationships

Colors = thematic clusters

For example:

A keyword map may reveal that "machine learning," "deep learning," and "healthcare analytics" belong to the same research cluster.

These visual insights help researchers:

Identify hot topics

Detect research gaps

Understand collaboration networks

Explore emerging trends

Common Mistakes to Avoid

Even though VOSviewer is user-friendly, beginners often make a few mistakes.

Using Poor Search Queries

Broad keywords create noisy datasets.

Ignoring Data Cleaning

Messy metadata leads to misleading results.

Overinterpreting Visual Maps

Visualization supports analysis, but context still matters.

Using Small Datasets

Very limited data may not produce meaningful networks.

Researchers emphasize that bibliometric studies should combine quantitative mapping with thoughtful interpretation for reliable conclusions.

Final Thoughts

The growth of academic publishing has positioned bibliometric analysis as a valuable asset to researchers, postgraduate students, and other academics, as well as the institutions they populate.

With the aid of software like VOSviewer, the task of literature reviews becomes even simpler. Forget the tedious paperwork and the scouring of thousands of papers. If you want to find key studies, research hidden trends, and visualize the landscape of a field of research, this program does it all in a matter of minutes.

The most exciting aspect of VOSviewer?

You do not have to learn a new programming language.

With the appropriate data, research questions, and clean metadata, software like VOSviewer has the power to convert complex information into useful visual information.

Engaging in bibliometric analysis might help you comprehend more about the research in your field and aid you in writing your literature review, thesis, or in taking a more strategic approach when tackling new areas of research.
