 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

 Analysis
 Individual Researcher: calculate the yearly citation counts for a
researcher
 Groups of Researchers:
Calendar Year Citation/Publication Counts
 Career Year Citation/Publication Counts
 Career Year Citation/Publication : Average Counts Ratio
 Rank the Researchers

Evaluation
