This paper discusses methods enhancing the selection of a ``best''
parsing tree from the output of natural language syntactic analysis.
It presents a method for cutting away redundant parse trees based on
the information obtained from a dependency tree-bank corpus.

The effectivity of the enhanced parser is demonstrated by results of
inter-system parser comparison. The test were run on the standard
evaluation grammars (ATIS, CT and PT), our system outperforms the
referential implementations.
