A fundamental step in sentence compre- hension involves assigning semantic roles to sentence constituents. To accomplish this, the listener must parse the sentence, find constituents that are candidate argu- ments, 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 pa- per we focus on the parsing and argument- identification steps that precede Seman- tic Role Labeling (SRL) training. We combine a simplified SRL with an un- supervised HMM part of speech tagger, and experiment with psycholinguistically- motivated ways to label clusters resulting from the HMM so that they can be used to parse input for the SRL system. The results show that proposed ...
