This paper presents a method for the syntactic parsing of Hungarian
natural language texts using a machine learning approach. This method
learns tree patterns with various phrase types described by regular
expressions from an annotated corpus. The PGS algorithm, an improved
version of the RGLearn method, is developed and applied as a classifier
in classifier combination schemas. Experiments show that classifier
combinations, especially the Boosting algorithm, can effectively improve
the recognition accuracy of the syntactic parser.
