Create an item used to create a pattern/line in the Stanford CoreNLP regular expression definition file with a regex created from content and NER label.

The opts parameter are keys with:

• :lem-min-len minimum item utterance length to turn on lemmatization for the last token (default -1), for example:
  • 2: if the string is or longer than 2 chars lemmatize the last token
  • 0: always lemmatize
  • -1: never lemmatize
• :case-min-tok must have at least N tokens to turn on case sensitivity (default to -1), for example:
  • 2: if there are 1 or 2 tokens make it case sensitive
  • 1: if there is only one token then make it case sensitive
  • 0: always case sensitive
  • -1: always case insensitive
• :conj-regexp? add and|& regex to match both symbols, defaults to true
• :first-det-chop? chop off ‘the’ at the beginning of the item utterance, defaults to true
• :is-regexp? if true write the regular expression verbatim instead of generating one from the utterance like form

Write all items to the Stanford token regular expression files regex-output-file with all possible features in features-output-file.
