A new Just KNIME It! challenge has just been released!
This week we have our first hard challenge, focusing on sentiment analysis over tweets, and relying a lot on text processing techniques. To make the task easier for those who do not know much about text processing, we are sharing two components that may come in handy and can be adapted by you for your solution.
Here is the challenge. Let’s use this thread to post our solutions to it, which should be uploaded to your public KNIME Hub spaces with tag JKISeason2-6 .
Need help with tags? To add tag JKISeason2-6 to your workflow, go to the description panel on the right in KNIME Analytics Platform, click the pencil to edit it, and you will see the option for adding tags right there. Let us know if you have any problems!
Last few days of log attached. I’m using v. 4.7.2. This problem is affecting my installed components as well. See pic below. A component already in a workflow will run, but I can’t add a component to a new workflow. 2023-05-02 185028,102 ERROR Worke.txt (35.3 KB)
I created a workflow with the provided components.
Positive, negative and neutral were randomly selected 1,000 each to save time.
Apart from that, I did without a dictionary tagger for my study, referring to the education material [L4-TP].
I didn’t diagnose the problem, but I fixed it. I did a clean reinstall and everything seems to be fine. I’m still curious about what caused this. Identifying the cause may help avoiding the problem in the future.
