A SAS text analyst needs to score new documents into an existing latent semantic space created by PROC TEXTMINE's SVD. Which SAS procedure is used for this scoring step?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — b is correct because PROC TMSCORE is designed to score new documents into an existing text mining space. It applies the existing vocabulary, IDF weights, and SVD components from the original PROC TEXTMINE run (specified via TERMS=) to parse and project new documents into the same latent dimensions.

Full Explanation
B is correct because PROC TMSCORE is designed to score new documents into an existing text mining space. It applies the existing vocabulary, IDF weights, and SVD components from the original PROC TEXTMINE run (specified via TERMS=) to parse and project new documents into the same latent dimensions. A is wrong; PROC SCORE handles linear scoring matrices for regression-type models, not text mining SVD. C is wrong; PROC TEXTMINE does not have a MODEL= scoring option. D is wrong; PROC TEXTMINE does not produce ASTORE items.
