Author Topic: Creating ExampleSet from WVTInputList  (Read 1686 times)

Hello,
I have build a WVTInputList (as described in the tutorial) and created WordVector and WordLists.

Now I want to compare (similarity) the input documents, so I need an ExampleSet. It seems that I can use com.rapidminer.operator.TextInputOperator for "creating an ExampleSet from a collection of texts" (javadoc). But the documentation doesn't describe how to use this class.

So how do I get an ExampleSet from a WVTInputList or a list of WordVectors?

Hi,

I would directly use the operator instead of manually creating the WVTInputList. You can find many references to how this can be done (from files, from strings, from databases...) here in the forum. If you want to stick to the WVTInputList, you will need the RM text plugin anyway and use the ExampleTableOutputFilter (or something similar, I don't remember the exact name).

Cheers,
Ingo

Did you try our new Marketplace? Upload or download new Extensions, add comments, and organize your operators. Have a look at  http://marketplace.rapid-i.com

Unfortunately I didn't find anything that helped me in this forum. Maybe you could give me another hint?

Ok, i think i will try another approach the next days.

Maybe I come back for some questions then. But thank you for your help so far!
