SaarlandTdlDiscussion

TDL formalism discussion

Yi's slides

Open questions:

• Was the level of simplification correct?
• future extensions?
• Other uses? (other applications)

Glenn: model floating point numbers and integers

Ann: TDL syntax LKB Copestake 91, not Kreiger 95

oe: name our formalism DELPH-IN Typed Feature Structure (DTFS) Logic

Emily, Glenn, Ann: BNF in white book or appendix in green book

Woodley: what operations on floating points

Glenn: we lose precision differently between processors on POS probabilities

Yi: in deependence, treat them as a special case in particular places in FS

oe: not quite the original LKB formalism now: unique GLB requirement eliminated (in specification); only LKB has defaults; PET et al. support regular expressions, token mapping; etc.

Ann: logic hasn't changed, formalism may have

Yi: compatibility and extensionability

David: do you have URIs? (Yi: no) should you? for sharing code fragments

Woodley: do grammarians want disjunctions?

oe: we should have mechanism for conseratively changing as needed
