--feat_labelmap_lex

Switch

--feat_labelmap_lex LEXICON

Description

Name of a topic lexicon to derive feature labels from (e.g. showing each LDA topic's top words instead of its raw numeric id), used when displaying results.

Argument and Default Value

A lexicon table name. Default: ''.

Details

Can be supplied directly, or built automatically: when --make_topic_labelmap_lex is used, FeatureRefiner.makeTopicLabelMap(topiclexicon, numtopicwords, weightedlexicon) is called and its result is written into args.featlabelmaplex for you, using --num_topic_words top words per topic. See --feat_labelmap_table for the alternative, hand-built mapping table.

Other Switches

Optional Switches:

• --make_topic_labelmap_lex (builds this automatically from --topic_lexicon)

• --num_topic_words

• --feat_labelmap_table (alternative source of labels)

• --bracket_labels (currently non-functional — see that page)
