    @student_compute it sounds like you want to use the Aylien extension. Download that from the Marketplace and then build your process. There are KB articles on how to use Aylien.

    Hello
    Thank you so much for your answer

    May I give you a training link?
    I did not find myself.

    Do you mean, operator
    sentiment base aspect?

    I clustered my data. Should I apply this operator to any cluster?
    Please help me to fix the problem:smileysad:

     

     

    I used it for example. This is my output.
    But I did not understand anything ...
    Why do not some rows have any aspect?
    What does this photo show?

    @student_compute I have no idea what you are doing based on that screenshot. It's like taking a photo of the Grand Canyon and then asking me where to find the bathrooms from that one image.  Please follow the Community rules by posting sample data and your process.

    Hello
    I used a review containing data
    Clustered the texts.
    Next in each cluster to summarize the cluster content from aspect base sentiment analysis
    I used.
    But only a few sentences have aspect value and the rest are empty
    Can someone help me to summarize the emotions of every cluster?
    In the process below, the Excel file is the same as my clustering result on the data stored in Excel

    @student_compute Aylien has a daily limit of 1000 rows, so you'll run into that limitation quickly.

    @student_compute I don't use the Aylien extension, so I don't know how it works. I usually use the Wordnet extension to do any sentiment analysis. I go over it in this video: https://www.youtube.com/watch?v=0TnDW87nt58
