Analyzes the case of every token (adds additional flags) and optionally adds a lower case normalized token to the interpretation graph.
Operates On: Lexical Items with TOKEN 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
Configuration Parameters
-
normalize ( type=boolean
| default=true
| optional
)
- If true, all tokens are normalized to all lower case
$action.getHelper().renderConfluenceMacro("$codeS$body$codeE")
Example Output
V--[Sentence]--V--[with]--V--[UPPER]--V--[and]--V--[LoWer]--V--[Words!]--V
^--[sentence]--^ ^--[upper]--^ ^--[lower]--^--[words!]--^
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:
- ALL_LOWER_CASE - All of the characters in the token are lower case characters.
- ALL_UPPER_CASE - All of the characters in the token are upper case characters (for example, acronyms).
- TITLE_CASE - The first character is upper case; all of the other characters are lower case.
- MIXED_CASE - Handles any mixed upper & lower case scenario not covered above.
- LOWERED - Applies only to tokens that were changed to all lower case; preexisting tokens with all lower case will not be marked with this flag.
