This stage identifies tokens that looks like URL addresses and flag them as "URL".

Operates On:  Lexical Items with TOKEN and possibly other flags as specified below.

Stage is a Recognizer for Saga Solution, and can also be used as part of a manual pipeline or a base pipeline


Currently handles the following situations:

  • HTTP and HTTPS protocols: http://mydomain.com, https://mydomain.com
  • Domains: www.my_domain.com, http://www.blog.my_2nd_domain.com
  • IP address (with protocol): http://235.156.13.10/
  • Ports: http://mydomain.com:9890
  • Paths: http://mydomain.com/path/to/dir.html
  • Parameters and anchors, query strings: http://mydomain.com/path/to/dir.html?var1=true+or+false&setFlag, http://mydomain.com/path/to/dir.html#section2
  • Encoding: http://mydomain.com/path%20to%20dir

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

  • domain ( type=boolean | default=false | optional ) - Enable recognition for domains. (e.g www.mydomain.com)
  • url ( type=boolean | default=false | optional ) - Enable recognition for urls. (e.g http://mydomain.com)

"domain": false,
"url": true

Output Flags

Lex-Item Flags:

  • SEMANTIC_TAG - Identifies all lexical items which are semantic tags.
  • URL - Identifies the token as an URL address
