Building a sentiment analysis model in SAS viya so that can be used by model studio

[nadaelmo]

Hello Everyone, 

I am building a text analytics model in Model studio using Text Analytics 8.5. The sentiment node doesn't have an interactive window, which is unfortunate, so I am trying to build a custom sentiment model so that it can catch certain phrases and assign the correct sentiment. I can't seem to find documentation that explains how to make your own sentiment model and then import into model studio so that text model can use it. Does anyone have any reference documents?

If your pipeline includes a sentiment node, the results of document level sentiment   will be included in the topic and the category node output.
