Dear Siniraju,

unfortunately, your problem description is not precise enough to be any more specific than I was in my first reply. If you have specific questions regarding your application, this forum is probably not the right place to discuss them. I would recommend you to attend one of the introductory data mining courses listed on

http://rapid-i.com/content/view/7/95/lang,en/

In such a course, we can also elaborate on your specific problem.

Best,
Simon

Dear Siniraju,

There are several solutions for your problem, hoewever, all of them are independent of whether the data comes from a CSV file or some other data source.

- Try an ExampleFilter with an attribute_value_filter parameter to filter only matching lines.
- Use an AttributeConstruction to set an attribute to 1 if it matches and 0 otherwise. Then use Aggregation to count.

Use an AttributeFilter.
