Implementation of sentence constrained LDA into Knime

Hello everyone,

on recommondation of my Professor I’m using Knime for my master thesis. I try to analyse customer reviews from a Yelp dataset on the influence of Service quality on Customer satisfaction. It was also recomended to use SC-LDA, which is based on a Paper: Büschken, J., & Allenby, G. M. (2016). Sentence-based text analysis for customer reviews. Marketing Science , 35(6), 953-975. First I taught to just split the reviews into single sentences but in after reading the paper completely I saw that there is more to it than just that.

Now to my question: I’m not quiet shure what this adaption changes and how or if i can add this into knime? Can somebody help me with that?

Here are some bits of the paper:
