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

)
- 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

-
enable ( type=boolean
| default=true

"caseInsensitive" : true,
"stopWords" : "words-provider:stop_words"
}
Example Output
V--------------[A test to be skipped]--------------V
^--[A]--V--[test]--V--[to]--V--[be]--V--[skipped]--^
^--[a]--^
Item [A] - [TOKEN, SKIP]
Item [to] - [TOKEN, SKIP]
Item [be] - [TOKEN, SKIP]
Item [a] - [TOKEN, SKIP]
Output Flags
Lex-Item Flags:
- SKIP - All matched stop words will be marked as SKIP
Resource Data
The resource data will be a json file with an array of words in a field named stopWrods
{
"stopWords": ["a", "about", "above", "after", "again", "all", "am", "an", "and", "the", "i", "who", ...]
}
