Purpose
To investigate the use of the text mining/data visualization tool OmniViz™ as a way to:
•Help us understand patterns in our portfolio that could inform the management of science in a new way.
•Visualize the assignment of grants to program officers.
•Explore emerging areas of science.
•Identify gaps in research.

The Process:
1. Obtain our active grant portfolio data.
2. Limit our data set by grant type and program to focus on our Research Grant Program portfolio.
3. Import data into OmniViz.
4. Select text mining algorithm.
5. Identify words to eliminate in the text mining algorithm. (stop words)
