Hi , I am new to Knime and Ineed your help with my project…
I initially have a raw data like this :
then, i used category to number node to insert number value to each, like this :
I want to combine it both so that I can continue the association mining process, this is my desired output :
How should i do it? May I ask, which node i should use? Thankyou so much !!!
Here’s an example workflow, which I think does what you’re asking:
Hi @KainLittleCloth ,
You can use the Cell Replacer to do this. The Cell Replacer allows you to replace based on a dictionary/mapper.
The challenge is to replace multiple “words” in the same cell. You can break them down by playing around with GroupBy/Ungroup.
Something like this will work:
Here’s the workflow: Replace mapped value for association mining process.knwf (15.7 KB)
For this particular case, I would recommend to look at example below
Dictionary tagger could be skipped and String manipulation node needs to be added to replace comas by spaces.
Just 5 nodes to get result.
@izaychik63 @elsamuel Thankyou so much for your reply!! But I don’t have knime extension so i couldn’t use one of the node stated in your solutions…
But managed to the get solution proposed by @bruno29a !! Thankyou very much for your help!!!
To get extension installed, download example and open (double-click) it in KNIME. KNIME will ask you if you want to install missing extension. Good luck.
