Splits text blocks into separate tokens on any number of white spaces.
Operates On: Lexical Items with TEXT_BLOCK and possibly other flags as specified below.
Generic Configuration Parameters
-
boundaryFlags ( type=string array
| optional
)
- List of vertex flags that indicate the beginning and end of a text block.
Tokens to process must be inside two vertices marked with this flag (e.g ["TEXT_BLOCK_SPLIT"]) -
skipFlags ( type=string array
| optional
)
- Flags to be skipped by this stage.
Tokens marked with this flag will be ignored by this stage, and no processing will be performed. -
requiredFlags ( type=string array
| optional
)
- Lex items flags required by every token to be processed.
Tokens need to have all of the specified flags in order to be processed. -
atLeastOneFlag ( type=string array
| optional
)
- Lex items flags needed by every token to be processed.
Tokens will need at least one of the flags specified in this array. -
confidenceAdjustment ( type=double
| default=1
| required
)
- Adjustment factor to apply to the confidence value of 0.0 to 2.0 from (Applies for every pattern match).
- 0.0 to < 1.0 decreases confidence value
- 1.0 confidence value remains the same
- > 1.0 to 2.0 increases confidence value
-
debug ( type=boolean
| default=false
| optional
)
- Enable all debug log functionality for the stage, if any.
-
enable ( type=boolean
| default=true
| optional
)
- Indicates if the current stage should be consider for the Pipeline Manager
- Only applies for automatic pipeline building

Output Flags
Lex-Item Flags:
- ORIGINAL - Identifies that the Lex-Items produced by this stage are the original, as written, representation of every token (e.g. before normalization).
- ALL_LETTERS- All of the characters in the token are characters.
- ALL_PUNCTUATION - All of the characters in the token have punctuation.
- ALL_DIGITS - All of the characters in the token are digits (0-9)
- TOKEN - All tokens produced are tagged as TOKEN
- HAS_LETTER - Tokens produced with at least one letter character are tagged as HAS_LETTER
- HAS_DIGIT - Tokens produced with at least one digit character are tagged as HAS_DIGIT
- HAS_PUNCTUATION - Tokens produced with at least one punctuation character are tagged as HAS_PUNCTUATION. (ALL_PUNCTUATION will not be tagged as HAS_PUNCTUATION)
Vertex Flags:
- ALL_WHITESPACE - Identifies that the characters spanned by the vertex are all whitespace characters (spaces, tabs, new-lines, carriage returns, etc.).
