TAILIEUCHUNG - Báo cáo khoa học: "Optimality Theory: Universal Grammar, Learning and Parsing Algorithms, and Connectionist Foundations"

The talk proceeds as follows: (1) we summarize OT and its applications to UG. The we present (2) learning and (3) parsing algorithms for OT. Finally, (4) we show how crucial elements of OT emerge from connectionism, and discuss the one central feature of OT which so far eludes connectionist explanation. (1) In OT, UG provides a set of highly general universal constraints which apply in parallel to assess the wellformedness of possible structural descriptions of linguistic inputs. | Optimality Theory Universal Grammar Learning and Parsing Algorithms and Connectionist Foundations Abstract Paul Smolensky and Bruce Tesar Department of Computer Science and Institute of Cognitive Science University of Colorado Boulder USA We present a recently proposed theory of grammar Optimality Theory OT Prince Smolensky 1991 1993 . The principles of OT derive in large part from the high-level principles governing computation in con-nectionist networks. The talk proceeds as follows 1 we summarize OT and its applications to UG. The we present 2 learning and 3 parsing algorithms for OT. Finally 4 we show how crucial elements of OT emerge from connectionism and discuss the one central feature of OT which so far eludes connectionist explanation. 1 In OT UG provides a set of highly general universal constraints which apply in parallel to assess the well-formedness of possible structural descriptions of linguistic inputs. The constraints may conflict and for most inputs no structural description meets them all. The grammatical structure is the one that optimally meets the conflicting constraint sets. Optimality is defined on a language-particular basis each language s grammar ranks the universal constraints in a dominance hierarchy such that each constraint has absolute priority over all lower-ranked constraints. Given knowledge of UG the job of the learner is to determine the constraint ranking which is particular to his or her language. The explanatory power of OT as a theory of UG has now been attested for phonology in over two dozen papers and books . McCarthy Prince 1993 Rutgers Optimality Workshop 1993 applications of OT to syntax are now being explored . Legendre Raymond Smolensky 1993 Grimshaw 1993 . 2 Learnability of OT Tesar Smolensky 1993 . Theories of UG can be used to address questions of learnability via the formal universal principles they provide or via their substantive universals. We will show that OT endows UG with sufficiently tight formal .
