The Exercises

Step 1: Research conceptualization

Step 2: Scientific screening

Step 3: Scientific and Patent Landscapes

Step 1: Research conceptualization

Research question

🎯 Goal:

  • Based on the canvas, Identify a research question from a general topic that you want to study.
    • Define two or three specific research topics that complete the general research question.

Step 3: Scientific and Patent Landscapes

scientific and the Patent landscapes

🎯 Goal: Create a detailed description and facilitate a discussion on the visualizations generated by VOSviewer.

  • Focus on interpreting how the clusters identified relate to the research question.
  • Examine key patterns and connections.
  • Uncover insights into the relationships among concepts and themes.
  • Make a description enhancing the understanding of the research landscape.

Bibliometric mapping: Vosviewer

VOSviewer

Functions of VosViewer:

  1. Create maps based on network data.
  2. Visualize and explore the maps.

📕  Offical Manual of VOSviewer

VOSviewer: Terminology

  1. Maps are created by items
  2. Items are object of interest → 📚Publications, 👩🏻‍🔬👨🏻‍🔬Researchers or 🔤Terms
  3. Links are the relations between two items.
    • Each link has a Strength → Positive number. The higher, the stronger.
      For instance:
      • Bibliographic coupling : Number of cited references two publications have in common.
      • Co-authorship: number of publications that two researches have co-authored.
      • Co-occurence: Number of publications in which two terms occur together.
  4. Clusters are a group of items

Entities in OpenAlex

OpenAlex will identify these metadata:

  • Works → Articles, Conferences, Books.
  • Authors → Names, Institutions
  • Institutions → Name, location..
  • Funding → APC

The idea is to obtain the metadata of the scientific documentation.

Metadata on OpenAlex

Source. OpenAlex documentation

Metadata on OpenAlex

Source. OpenAlex documentation

Search on OpenAlex

Structure of the search equation:

(key1 OR key2) AND (key3 OR key4) AND (key5 OR key6)

Interface on OpenAlex

Type of search:

  • Works
  • Authors
  • Sources
  • Institutions

Filters on OpenAlex

  1. Filters are the basis of query-building and allow searching of entities, attributes, and text.

Currently 47 filters are available in the UI.

Works on OpenAlex

Each work can be identified

Connecting of OpenAlex

  • Using the API
  • Less than 50000!!

  • Developed at CWTS

Co-Authorship Analysis

Add data: from Bibliographic database file

Add data: from Bibliographic database file

Add data: Select the .txt files from WoS

Select: Co-Authorship

You can see the types of analysis. Use this ﹖icon to see the relatedness for each type of the analysis:

Select Co-Authorship

Select: Thresholds

In fonction of the type of ‘Co-Authorship analysis’ (Authors, Organizations, Countries), different type of threholds are proposed:

Authors

Organizations

Countries

Co-Occurence of Keywords

Add data: Minimum number of Occurrencies for Keyworkds

Add data: Keywords to be plotted

Add data: Verify if Keywords are correct

Attention to the Redundancies

Network Visualitation

Overlay Visualitation

Overlay Visualitation: Selecting the node

Density Visualization

Patents Network visualization
