PROC TEXTMINE processes a collection of legal contracts. The RULES statement is included in the PROC TEXTMINE call. What does the RULES statement enable?
Select an answer to reveal the explanation.
Short Explanation
You use the RULES statement to group synonyms and related terms into one concept before the term-document matrix is built. It’s for term normalization, not document filtering or association mining.
Full Explanation
The RULES statement in PROC TEXTMINE lets analysts define custom term synonyms, equivalences, and grouping rules. For example, 'liability', 'liabilities', and 'liable' can be grouped under a single concept. This is applied during parsing before the term-document matrix construction, improving the quality of text features for downstream analysis. The metadata inclusion/exclusion option is wrong because document filtering is done at the data preparation stage, not RULES. The association-rules option is wrong because association rule mining (Apriori) is done by PROC DMDB/Enterprise Miner, not PROC TEXTMINE RULES. The regular-expression entity-extraction option is wrong because regular expression entity extraction is done by the Text Parsing CAS action or SAS Visual Text Analytics, not PROC TEXTMINE RULES.
