Type Description Language and other aspects of DELPH-IN Joint Reference Formalism

Case Sensitivity

Case Sensitive

• Things inside quotes (NB: strings passed from TFS world into MRS can be treated as case insensitive in MRS processing (i.e. as predicate symbols, but not CARGs)

Case Insensitive

• Everything in TDL not inside of quotes.
• Lexicon look-up.
  • Proper names?
  • Acronyms?
• .. approach these with token-mapping (preserve the info, and then downcase anyway)

Unknown

Notes: Arguments for case insensitive include shouting (call caps); Arguments for case sensitive include the use of upper case vowels in vowel harmony languages (linguistic representations, not orthography)

TDL types allow a doc string:

n_-_c_le := n_intr_lex_entry &
"Intransitive count noun (icn)
