Details

Specifies the name of the table containing extracted features. Features are usually created using one of the steps in Feature Extraction.

Expected column format of the table must/will contain at least the following:

  • group_id: Contains the "group_id" id-s (i.e. type specified by -c). Is an index.
  • feat: Contains the feature type. Could be n-grams, lexicon features, etc.
  • value: Contains the straight up count of the feature for the group_id. For ngrams, is just occurrence count. For lexical features, is number of words matched for given feature & group_id.
  • group_norm: Contain the "relative frequency" of each feature. See specific feature extraction pages for how it actually works.
