This blog covers the functionality available in VA 7.3 Designer – Word Cloud. So if you have VA 7.3 then you have the Word Cloud object to use in your VA reports – and you can replicate everything I showed here in the blog and my screenshots. None of my screenshots in this blog use the text analytics functionality.

My understanding was that your question was about the text analytics, also known as sentiment analysis which is (https://en.wikipedia.org/wiki/Sentiment_analysis) the processing of text to identify if the text has a positive, neutral, or negative meaning. Frequently used words that do not add to the evaluation of sentiment are included in a Stop List and are ignored at processing (https://en.wikipedia.org/wiki/Stop_words). This functionality is immensely computationally intensive and which is why it is only available from the VA 7.3 Explorer. Those with access to Explorer are considered power users and have access to the other more computationally intensive analytic visualizations not available in Designer. To include it in VA 7.3 Designer for reports where it could potentially be hit by hundreds or thousands of users – it would not be performant.

The Word Cloud with text analytics is available with Viya VA 8.1 as Viya uses our next generation analytic engine with improvements to algorithms and multi-threading which allows us to make this visualization available for reports. Also, Viya, like our previous software versions, can be deploy on premise hardware or the cloud – so if your data isn’t cloud ready you can install on local hardware.
