      • getIntArray

        public int[] getIntArray​(java.util.Properties propDef,
                         java.lang.String propName)

      • offsetConjFromConfig

        public int[][] offsetConjFromConfig​(java.lang.String offset_conjunctions)
        extracts the offset conjunction information (feature creation horizon) from a String of the form (-1) (0) (1), (-1) (0) (1,2) or (-1) (0) (1 2)

      • getLexiconKeys

        public java.util.ArrayList<java.lang.String> getLexiconKeys​(java.util.Properties propDef)

      • getTrueMetas

        public java.lang.String[] getTrueMetas​(java.util.Properties featureConfig)
        The Properties Object featureConfig contains key-value pairs. Some of these pairs correspond to information about meta datas. This method returns a list of the used meta datas by searching for pairs of the form "xxx_feat_enabled = true". It then adds the "xxx" to the list. For "pos_feat_enabled = true" it will add pos to the list. For "chunk_feat_enabled = false" it will do nothing.

      • getStringArray

        public java.lang.String[] getStringArray​(java.util.Properties propDef,
                                         java.lang.String propName)
        Gets the value of a property, splitting it into Strings
        Parameters:
        propDef - Property file to parse
        propName - Property key to extract values for
        Returns:
        String[], containing the value split at "," or null, if not found
