Schwarz, Lara & Putnam, Michael T.: Expanding the Pipeline: A Prolegomenon to Modeling Multilingual Grammars in LFG
In light of evidence from
cognitive neuroscience that both source grammars are simultaneously active in
the mind of a bilingual, we discuss the ramifications this has on the modeling
of outputs from bilingual grammars, especially those that contain elements from
multiple source grammars (i.e., code-switching). Here we provide a sketch of the
architectural assumptions necessitated in light of these findings. To best model
these structures, we introduce an expanded pipeline architecture that builds
upon the foundation of previous work by Asudeh and Toivonen (2015). Similar to
previous work integrating violable constraints from Optimality Theory (OT)
(Prince and Smolensky, 2008) into LFG’s parallel correspondence architecture
(Bresnan, 2000; Sells, 2001a,b), we augment this architecture with gradient,
probabilistic mapping functions between the independent levels of grammar as
initially suggested by Goldrick et al. (2016a).
