--gzip_csv

Switch

--gzip_csv FILENAME

Description

Extracts n-gram features directly from a gzipped CSV file of messages, instead of a message table given by -t.

Argument and Default Value

Path to a .csv.gz file. Default: '' (not used).

Details

Verified from source: this switch is only checked inside the --add_ngrams code path (if args.addngrams: ... elif args.gzipcsv: ...), so you must pass --add_ngrams together with --gzip_csv — it is not a standalone alternative to it. Routes to FeatureExtractor.addNGramTableGzipCsv() with a hardcoded column layout (message-id column 3, group-id column 0, message column 19) — this is a fixed-format bulk-import path for a specific corpus layout, not a general-purpose CSV reader. Use -n to control which n-gram sizes are extracted.

Other Switches
