Splits tokens on specified characters, typically punctuation. Multiple split characters in a row will create a single split (not multiple splits).
Operates On: Lexical Items with TOKEN
Configuration
Parameters
- splitChars (string, optional) - List of characters which should be used to split tokens.
- If not present, then tokens are split on any sequence of punctuation.
- dontSplitChars (string, optional) - 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 splitChars is missing.
- These characters are included in the produced tokens.
- splitFlag (string, optional) - The flag to be put on the vertex between the two tokens.
- If missing, defaults to ALL_PUNCTUATION.
Examples
{
"type":"CharacterSplitter",
"dontSplitChars":"."
}
Splits on all punctuation, except periods.
For example, the token: "SagaToolkit-1.0" will produce the following graph:
V-------[SagaToolkit-1.0]-------V
^---[SagaToolkit]--V--[1.0]----^
{
"type":"CharacterSplitter",
"splitChars":"-",
"splitFlag":"DASH_SPLIT"
}
(splits tokens dashes)
Output Flags
Lex-Item Flags:
- TOKEN - All tokens produced are tagged as TOKEN
Vertex Flags:
- ALL_PUNCTUATION - Identifies the vertex as all token
- The default flag if no "splitFlag" is present.
- <splitFlag> - Defines an alternative flag to ALL_PUNCTUATION, if desired (see above)
