Awkward Error on Dictionary Based Sentimental Analysis Process

Melihck · December 2020

Hi there!

While I am exploring the sentimental analysis I found an XML process from @Benedict_von_Ah mschmitz in the forum.

In their model, they basically put the text into the create_document operator. But in my case, I had to use a dataset because I am working with Tweets. After I made the changes the error the below appears:

My XML is below if anyone can help I would definitely appreciate it🙏.
Also, I would love to see different models with more emotions like "fear" "anger" "joy" etc. instead of positive and negative. Please up me if you know any.

Thanks in advance for your help and for this amazing software.

I added the files in case of need.

Thanks a lot

MartinLiebig · December 2020

Hi,

The operator expects documents, not tables. Please try Data to Documents and have a look at the tutorial process.

Best,

Martin

Hi, @mschmitz thanks a lot.

I tried data to documents operator already. But this time it gives the error below:

And about the tutorial, I was thinking to explore the "text and web mining" tutorial. I saw the headline "Automatic Classification of Documents" and maybe I can use it for the sentimental analysis. But if you have any other starting point I would appreciate it.

Best!
Melih

hello @mschmitz thank you very much for your posts. My question is how can I group the "scoring string" obtained in the above model. Then how can I sum the string values? Thank you

Hi @akinozen; thanks! It's really helped, now I can calculate the positive and negative scores of texts.

But now I just noticed that dictionary-based sentimental operator designed for only negative and positive indicators. If I am wrong please correct me @mschmitz. Because I want to define different attributes like Anger, Anticipation, Disgust, etc.

I will try to do it with the "old-trick" where @jacobcybulski mention here: https://community.rapidminer.com/discussion/comment/64839#Comment_64839

Hopefully, it will work. Thanks again for your support.

MartinLiebig · December 2020

@Melihck ,

no need to use @jacobcybulski 's trick. I mean the operator just calculates a score. It can be Anger, Digust etc. You just need to have the right dictionary.

Best,

Martin

@mschmitz

How can we sum the scores of each category (anger, disgust etc) in the scoring string table? Can you suggest a dictionary of sentiment with verified scores? I use the dictionaries in the link. dictionary link: http://sentiment.nrc.ca/lexicons-for-research/

I want to create my result table according to my input dictionary and I want to sum the scores.

I am grateful for your help.
