Separates tokens based on character changes from lowercase-uppercase, letter-number, alphanumeric-punctuation.Without taking any character in the vertex, and respecting the capital letter
Operates On: Lexical Items with TOKEN flag
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
Configuration Parameters
- case (boolean, optional) - If true, all tokens are separated on a case change (default = true)
- number (boolean, optional) - If true, all tokens are separated on a letter-number. (default = true)
- punctuation (boolean, optional) - If true, all tokens are separated on an alphanumeric-punctuation. (default = true)
{
"type":"CharChangeSplitter",
"case": true,
"number": true,
"punctuation": true
}
Output Flags
Note that flags are placed on every token as appropriate to the current token:
- If the token is "President" then that token will have the TITLE_CASE flag.
- If a new lower-case normalized interpretation, "president" is added as an alternative, this alternative will have the "ALL_LOWER_CASE" flag.
Lex-Item Flags:
- TOKEN - All tokens produced are tagged as TOKEN
- ALL_PUNCTUATION - Tokens processed or produced composed only of punctuation characters are tagged as ALL_PUNCTUATION
- 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:
- CHAR_CHANGE - Identifies the vertex as a change between character formats
