text: These experiments were dual purpose : -LRB- 1 -RRB- to validate the central thesis of the work of -LRB- Levin , 1993 -RRB- , i.e. , that verb semantics and syntactic behavior are predictably related ; -LRB- 2 -RRB- to demonstrate that a 15-fold improvement can be achieved in deriving << semantic information >> from [[ syntactic cues ]] if we first divide the syntactic cues into distinct groupings that correlate with different word senses .
