extract_features: To extract features of an object

In sanmai-NL/feat: Extract (Linguistic) Structural and Surface Features from XML Documents

Description

Extracts features of an object given a feature representation.

Usage

extract_features(object, FEATURES_EXTRACTION_PARAMETERS, OBJECT_ID_I,
  OBJECT_OUTPUT_DIR_PATH_STR, RELATIVE_FILE_PATHS_CVEC)


  ## S4 method for signature 
## 'SrfFeatureRepresentation,
##   FeaturesExtractionParameters,
##   integer,
##   character,
##   character'
extract_features(object,
  FEATURES_EXTRACTION_PARAMETERS, OBJECT_ID_I, OBJECT_OUTPUT_DIR_PATH_STR,
  RELATIVE_FILE_PATHS_CVEC)


  ## S4 method for signature 
## 'StrctFeatureRepresentation,
##   FeaturesExtractionParameters,
##   integer,
##   character,
##   character'
extract_features(object,
  FEATURES_EXTRACTION_PARAMETERS, OBJECT_ID_I, OBJECT_OUTPUT_DIR_PATH_STR,
  RELATIVE_FILE_PATHS_CVEC)

Arguments

object	See: StrctFeatureRepresentation and SrfFeatureRepresentation.
FEATURES_EXTRACTION_PARAMETERS	See: FeaturesExtractionParameters.
OBJECT_ID_I	The object_ID of the object.
OBJECT_OUTPUT_DIR_PATH_STR	The directory path for output about the object.
RELATIVE_FILE_PATHS_CVEC	The file paths relative to the documents root directory that collectively represent the object.

Value

OBJECT_FEATURES_DVEC Object features. May be DUMMY_OBJECT_FEATURES_DVEC, a single zero score for the feature named after the empty string. This is the case when from one or more objects no structural features could be extracted given the feature representation parameters.
