Very strange - parameter changes during csv generation

spokspok

Hi,

I´m rather new and try text mining with some 100s of documents. I tokenize, filter stopwords, use porter stemmer, filter by lenght, transform to lower case and wright the result to csv.

In the csv file some stemmed words have propabilities in the range of 10e+11, althought they have propabilities well below 1 in the example set table in rapidminer (as it should be to my opinion).

This effect is reproducable and seems to happen cumulative at certain parameters (words).

The effect occurs also if I copy and paste the example set matrix from rapidmier into excel.

What goes wrong??????

Many thanks for any assistance

Hi, I know this post is very old, but I recently had the same problem. It is probably a bug. I compared the results in both rapidminer and csv. Its an error with the engineering notation. In rapidminer, let's suppose the results are written in engineering notation with a MINUS (e.g. 10E-11). When writing these results to csv, they suddenly change to PLUS (e.g.10E+11). That's the error. Any solutions, rapidminer team?
