Hello,
I applied a TOPIC EXTRACTOR (PARALLEL LDA) node.
I would like to add the “TOPIC SCORER” node, but I have difficulty setting it up.
Who could help me?
Thank you Monica
See if this helps.
Hi, rfeigel,
Can I ask you for some details on how you configured the “constant value column” and " topic scorer" nodes?
I always get a process abort message from the " topic scorer" node.
Thanks,
Monica
You’re more likely to get help if you can share your workflow. In the meantime open the scorer component and see exactly where its failing.
Hi, this should be the work flow link. https://hub.knime.com/s/fS838m6zW0tmPQ9l
And this the error message.
The method join(java.lang.String…) in the type org.knime.base.node.preproc.stringmanipulation.manipulator.JoinManipulator is not applicable for the arguments (java.lang.String, java.lang.Integer, java.lang.String, java.lang.String, java.lang.String)
Line : 66 public java.lang.String internalEvaluate() throws Abort {
Line : 67 return join("MODELID: “,__col3,” // ","TOPICID: ",__col4);
The workflow is in your private space. I have no access.
I put it in public space.
Thanks
Your data is stored locally on computer. Create a “data” folder in side your workflow folder and store the data there.
I think I found the problem. You had integers for the model Ids which wouldn’t work with the downstream String Manipulation node. I added two Number to String nodes which fixed the problem although it probably would be more elegant simply fix the problem upstream. I’m old and lazy so I took the easy way out. While fooling around with your workflow I changed a number of the parameters. You can change them as you see fit.

Thank you rfeigel,
I tried, but unfortunately the node breaks even if Model id is a string.
I can’t help without more detail. Did you try the second workflow I posted? It works for me.
