I´m new to LDA and doing some experiments with Python + LDA and some sample datasets. I already got some very interesting results and now I asked myself a question but couldn´t find an answer so far. Since I worked with customer reviews/ratings of a certain app the documents contain different topics (e.g. one talks about the app performance, price, functionality). So for my understanding I got three topics within one document.

My question: Is LDA capable to assign more than one topic to one document?

Thank you for your answer!

Yes, this is the whole idea of LDA - is searched for topic distribution inside the documents. So it will assign several topics to documents (unless they are too short).
