Reader Nodes: Allow Type Collection (List or Set)

[mwiegand]

Hi,

while giving support in:

Category to class = "undefined"

Hi everyone, I am performing dictionary-based sentiment analysis on the KNIME analytics platform. However, when I run the Category to Class node, it returns ‘undefined’. I have been unable to solve this problem. Below, I am providing the workflow and the data I used. Can you please help me? Thanks everyone in advance. final2.knwf (64.9 KB) Since my data file is quite large, I’m providing the Kaggle link. I used the Books_rating.csv file.

I read books_data.csv from:

Amazon Books Reviews

The CSV contains collections of the type set but the CSV reader does not allow to import this data type. I know there can be various types of collections.

Nevertheless, I’d like to suggest bare minimum support to allow reading the type collection of strings in the CSV Reader.

Best
Mike

Hi @mwiegand ,

Since I’m working with the Books.rating.csv file, I’m not sure how to adapt this situation for myself. Nevertheless, thank you.

I apologize profusely. I’m new around here and still exploring.
