>Title:
>Starting From Scratch in Semantic Role Labeling
>
>Abstract:
>A fundamental step in sentence comprehension involves assigning  semantic 
>roles to sentence constituents. To accomplish this, the listener must parse 
>the sentence, find constituents that are candidate arguments, and assign 
>semantic roles to those constituents. Each step depends on prior lexical and 
>syntactic knowledge. Where do children learning their first languages begin 
>in solving this problem? In this work we attempt to train a Semantic Role 
>Labeling system with only high level semantic feedback and 
>psycholinguistically-motivated background knowledge.  We combine a 
>simplified SRL with an unsupervised HMM part of speech tagger trained on 
>actual child directed speech.  The results show that proposed shallow 
>representations of sentence structure are robust to reductions in parsing 
>accuracy, and that the contribution of alternative representations of 
>sentence structure to successful semantic role labeling varies with the 
>integrity of the parsing and argument-identification !
