Google Scholar

Google Scholar Profile: track citations to your publications

Google Scholar

Search for researchers working on certain research topic

Overview

AimsMethodologyEvaluationFuture Research

5

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.

6

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

7

Methodology

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

8

Evaluation

Accuracy of calculating the yearly citation counts for an individual researcher.
