I am trying to do performance analysis of sentiment data retrieved from Twitter in excel format. But when I apply SVM or any other prediction model, it's showing an error of missing attribute. I am not able to figure out what to do. Please help.

    Without seeing your process it's hard to know exactly but this error is telling you that the data you're training on, has no label or target variable defined. I would use a Set Role operator before the Validation and set an attribute (column) as a 'label.'

    hello@lambamanika07欢迎来到the community! I'd recommend posting your XML process here (seehttps://youtu.be/KkgB5QXWXJ8and "Read Before Posting" on right when you reply) and attach your dataset. This way we can replicate what you're doing and help you better.
