Syntax syntactic phrases

A question that has interested linguists for some time concerns the relationship between syntactic phrases (ie. the syntax tree) and prosodic phrasing. While there is clearly some relationship (easily seen in the above examples), finding the general nature of this is extremely difficult. Factors which complicate the relationship include ... 

More recently a number of approaches have been proposed which combine the advantages of decision tree approaches (use of heterogeneous features, robustness to curse of dimensionality) and the HMM approach (statistical, global optimal search of sequences). In addition, there has been somewhat of a re-awakening of use of syntactic features due to the provision of more robust parsers. Rather than attempt an explicit model of prosodic phrasing based on trying to map from the syntax tree, most of these approaches use the syntax information as additional features in a classifier [508], [209], [257].
