Aims

To collect research outputs by individual researchers from Google Scholar.

To develop techniques analysing the productivity of researchers.

To develop visualisation techniques that allow a presentation of the analyse.

Methodology

Data Crawling and Parsing Individual Researcher Groups of Researchers

Data Analysis Individual Researcher: yearly citation counts Groups of Researchers:

Calendar Year Citation/Publication Counts Career Year Citation/Publication Counts Career Year Citation/Publication : Average Counts Ratio Rank the Researchers
