Text classification

[alezonin]

Hello everyone, sorry if I ask trivial questions but I am taking my first steps with KNIME.

I need to classify each row of an excel sheet according to whether they contain one or more keywords.

My dictionary is like that.

type keywords-to-match
oriental foods, miso,tofu,ukicha,amasake,tahin,sitan,tempeh
fruits, apple,banana,pear,orange
vegetables, garlic,asparagus,beetroot,basil

My input looks like this

Text-to-classify
My family makes it kind of like a beverage?? Maybe like amasake?
How To Make Banana Bread? About garlic?
i’m a big fan of back hugs, tight hugs and forehead kisses

The desired output is like this:

Classified-text Type1 Type2 ….
My family makes it kind of like a beverage?? Maybe like amasake? oriental foods
How To Make Banana Bread? About garlic? fruits vegetables
i’m a big fan of back hugs, tight hugs and forehead kisses

Any suggestions are welcome. Thanks

Is this helpful?

It works and I thank you for it.

I have to try it on a large table. I think the “Cross Joiner” node can take a long time to run. I keep looking for a solution with nodes like “Dictionary Tagger” or similar.

Thanks again

You’re welcome.
Will explore “Dictionary tagger”.
How about this?

Unfortunately something is missing in my environment

Could not start Python executable at the given location (no_conda_environment_selected/bin/python): Cannot run program “no_conda_environment_selected/bin/python”: error=2, No such file or directory
Please refer to the log file for more details.

Yes, you will have to install Anaconda/Python to run this as it uses few libraries in the new node.
