Input Format

• Anything between parentheses or square brackets will be ignored, i.e. (...) or [...] will be deleted. The only exception is when [..] immediately follows a word. In this case, it signals an index variable. See explanation. below.

• Words are turned into lexical items. Words may be delimited by the following characters, mainly punctuation symbols:

  .

  ?

  #

  "

  '

  ,

  -

  carriage return

  tab

  space

  All other characters are considered to be letters of a word except for $ and square brackets [] to be described below.

• If a word is immediately followed by a left square bracket as shown below, an index feature is added to the word:

  word[chars]

  Examples: John[i], himself[j]

  In other words, chars is considered to be an index variable. Note: no intervening space is permitted.

• Characters * and # are ignored.

• % is a comment character. The rest of the line will be ignored.

  Example:

  [1:13a]	*Who does mary like john	% Vacuous operator

• The delimiter ' is treated specially. It is not discarded. It marks the end of a word but also forms the beginning of the next. For example, John's is analyzed as two words, John and 's.

• If a word is immediately followed by the dollar sign as shown below, a feature eng(..) is added to the word:

  word$word'

  Example: katta$buy, katta$keep

  word' maps into the feature eng(word'). This can be used to select appropriate translations. Note: no intervening spaces are allowed.
