Data labeling


I cleaned the data and for further analysis needs to label data. But I could not find how can I do it in Knime. Would you please help me!


Hi vida,
do you mean you want to manually add an existing column with a label to the table?
That’s currently not directly possible, however, we will have a new nice JavaScript Table Editor for that in the next release.
Currently, you could try to use the table creator and create two columns: one with a key identifying the row you want to assign the label to and the other with the label you want to assign. After that, you could use a joiner to add the labels to the other table.

Edit: The JavaScript Table Editor is already released in 3.5.

Hi @vida,
the easiest way to do the labeling is via the JavaScript table editor node, as @DaveK suggested. I have attached a workflow that demonstrates how to do this, as well as how to create a class column filled with missing value cells, where you can enter the class labels.
