That program will contain all the SAS code necessary to generate topics and can be run in batch.</P> Thu, 05 Jan 2017 21:27:33 GMT RussAlbright 2017-01-05T21:27:33Z Which sas procedure corresponds to the text topic node in the EM https://communities.sas.com/t5/SAS-Data-Science/Which-sas-procedure-corresponds-to-the-text-topic-node-in-the-EM/m-p/322039#M9665 Hi,<BR />Who knows which sas procedure corresponds to text topic node in the EM?

And it corresponds to the hptmine statement.
