Abstract:
This paper shows how underlying forms are learned by an
OT on-line learning algorithm. The proposed algorithm is
stupid: it processes one form at a time under one grammar
at a time. Stupid is good and effective: no extra learning
mechanisms are required than the ones already involved in
a general grammar learning model of OT (e.g. Boersma 1997).
Interpretation of incoming forms and constraint reranking
as a reaction to error detection is enough. Surface and
underlying forms are connected via faithfulness constraints,
and underlying forms are connected to meaning via lexical
constraints. It is shown that the learner can acquire grammar
and underlying forms concurrently, and creates an economical
lexicon.
