Syntactic Uninvert

  • Short Description: Syntactic uninvert the input phrase.

  • Full Description:

    This flow strips out non-information words (such as NOS, NEC); and then uninvert phrase around commas if the words after comma is not a conjunction words (such as about, beneath, where, yet).

    Non-information words are defined in file "data/misc/nonInfoWords.data". Conjunction words are defined in file "data/misc/conjunctionWord.data". Both non-information words and conjunction words are configurable.

    No effect on the -m option. "none" is added at the end of the output.

  • Difference:
    • The Java version drops comma if comma is at the end of the word after stripping the non-information words, such as "Kyphosis, NOS".
    • The Java version does not uninvert words if it is a conjunction word shows up after a comma at any position of the words; while the "C" version does not uninvert only if a conjunction word show up after the first comma.


  • Features:
    1. Strip non-information words.
    2. Tokenize phrase by using commas as delimiters.
    3. Check if the word after commas is a conjunction word.
    4. Uninvert input phrases around commas if above condition is false.
