Exclusive Filter: A Term contains pattern of incomplete

• Description:
  If a term contains pattern of incomplete, it is an invalid MWE. Incomplete patterns are terms that does not have even number of left and right parenthesis or square brackets or they are not closed. This filter also takes into consideration of core-term so that the input is a nGram. Patterns included are shown as the table below:

  Description	Incomplete Pattern
  uneven number of parenthesis	xx (yy xx ((yy) zz xx) yy (xx) yy) zz
  uneven number of brackets	xx [yy xx [[yy] zz xx] yy [xx] yy] zz
  unclosed parenthesis	xx) yy (zz
  unclosed brackets	xx] yy [zz

• Examples:
  • II (Hunter syndrome
  • 0.05) higher
  • bond]C-C[triple
  • (chi(2)

  This filter take core-term into consideration, such as XXX) will be convert to XXX and then check if it matches the incomplete pattern.

    Description	FilterType	Notes
    Assign default filter type	FT_INCOMPLET
    Check if a term is not incomplete (complete)	FT_TBD	check if number of left and right of parenthesis and square brackets are even check if parenthesis and square brackets are closed correctly
    Check if the core-term is not incomplete (complete). For example, "test" is the core-term of "(test", which is complete, thus "(test" pass this filter because core-term are used as LMW candidates at the end of these processes (this feature is updated in 2016).	FT_TBD	check if number of left and right of parenthesis and square brackets are even check if parenthesis and square brackets are closed correctly

    Please note the only trapped term from Lexicon, "antipoly ADP-ribose) polymerase", is an error in Lexicon.2014. It should be "antipoly (ADP-ribose) polymerase" and expected to be fixed in later version. In other words, the passing-rate is 100%.
