Hello
community,
I am
currently doing my masters degree and in one of our courses me and my group
have to work on a project with rapidminer. We have no background in programming
and this is the first time we are working with rapidminer. Our task is do
create a textmining tool that crawls a list of excel-files and in a first step
enables us to search for a list of keywords. We then need to know wether the
texts contain those keywords or not. We would also like to know how often a
keyword appears in those texts.
We tried
using the following operators:
1. SelectAttributes
2. Filter documents (by content) (we
created a loop that goes through the excel-file and wrote every text in a
separate document)
3. FilterExamples
However we
don’t really know how to use those operators because everything we’ve tried
(playing with the different options of the operators) didn’t work out.
Another
thing we thought about is to create a cut-set of the texts and the keywordlist
and see which elements the two files have in common (but again we don’t know
how to implement this).
Are we heading towards the right direction or do you have any tips how we should start?
I hope you
can help us
Cheers
Tim
