--add_lex_table

Switch

--add_lex_table [-l LEX]

Description

Add a lexicon-based feature table

Argument and Default Value

--add_lex_table -l <LEX> (where <LEX> is the name of the table)

Details

Given an existing N-gra,s table as your original feature table, this switch produces a new feature table where the features are now topics (as opposed to N:doc:fwflag_grams) based on the topics in the LEX table.

Unless -f is provided, the table feat$1gram$TABLE$GROUP_BY_FIELD$16to16 must be present.

Other Switches

Required Switches:

• -d, -g, -t, -l

Optional Switches:

• -f [alternative n-gram table; can be used in place of word table]

• --weighted_lexicon --anscombe, --sqrt, --log, --boolean (transformations, default is no transformation)

Example Commands

# Creates the table: feat$cat_LEX_TABLE$TABLE$GROUP_BY_FIELD$16to#
# In the above # = (1, 2, 4, 8, 16) and depends on the transformation (boolean, log, sqrt, anscombe and none, respectively)
./dlatkInterface.py -d DATABSE -t TABLE -c GROUP_BY_FIELD -add_lex_table -l LEX_TABLE

# Creates the table: feat$cat_met_a30_2000_cp_w$primals_new$dp_id$16to16
./dlatkInterface.py -d primals -t primals_new -c dp_id --group_freq_thresh 40000 --add_lex_table -l met_a30_2000_cp --weighted_lex
