--add_lda_table

Switch

--add_lda_table LDA_MSG_TABLE

Description

Adds a feature table of per-message LDA topic assignments, from an LDA-labeled message table (e.g. one created by --estimate_lda_topics, named <corptable>_lda$<name> — see -m).

Argument and Default Value

The name of an LDA-labeled message table. Default: None. Can be combined with --sqrt/--anscombe.

Details

Verified table naming (from source): creates feat$lda_<msgtable_component>$..., where <msgtable_component> is taken from splitting the LDA message table name on $.

Known issue — broken in SQLite mode. FeatureExtractor.addLDAFeatTable() calls mm.disableTableKeys(...) directly, the same pattern confirmed broken for --add_char_ngrams/--add_fleschkincaid/--add_outcome_feats. Expect sqlite3.OperationalError: near "DISABLE": syntax error after the destination table is created but before any rows are written.

Other Switches

Required Switches:

-d, -g, -t
An existing LDA-labeled message table (see --estimate_lda_topics)

Example Commands

Requires MySQL — broken against SQLite, see Known issue above:

dlatkInterface.py -d dla_tutorial -t msgs -c user_id --add_lda_table 'msgs_lda$dla_topics'
