Splits tokens on specified characters, typically punctuation. Multiple split characters in a row will create a single split (not multiple splits) when using the "Split as Vertex" setting.

Uses Character Splitter Stage

Configuration

  • Split Flag - The flag to be put on the vertex between the two tokens.
    • If missing, defaults to ALL_PUNCTUATION.

Tokenize Tokens

  • Token Delimiters - List of characters which should be used to split tokens
    • If not present, then tokens are split on any sequence of punctuation. 
  • Allowed Token Characters - List of characters which will NOT be used to split tokens.
    • This is typically used to identify exceptions (characters which are not used to split tokens) when Token Delimiters is missing.
    • These characters are included in the produced tokens.

Split Characters (Before/After)

  • Before character - if any character in this list occurs inside a token, that token will be split just before that character
  • After character - if any character in this list occurs inside a token, that token will be split just after that character

Split Characters

  • At start of token - true/false whether to split on all punctuation (default: true)
  • At end of token - true/false whether to split on all punctuation (default: true)


General Settings

The general settings can be accessed by clicking on 


  • Enable - Enables the processor to be used in the pipeline.
  • Skip Flags ( optional ) - Lexical items flags to be ignored by this processor.
  • Boundary Flags  ( optional ) - List of vertex flags that indicate the beginning and end of a text block.
  • Required Flags ( optional ) - Lexical items flags required by every token to be processed.
  • At Least One Flags ( optional ) - List of lexical item flags where at least one of them needs to be present to be processed.
  • Don't Process Flags ( optional ) - List of lexical items flags that are not processed. The difference with "Skip Flags" is that this will drop the path in the Saga graph, skip just skips the token and continues in the same path.
  • Confidence Adjustment - Adjustment factor to apply to the confidence value of 0.0 to 2.0 from (Applies for every 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 - Enable debug logging.
