Direct constituent analysis:A reflection on the debates of sentence analysis methods
LU Bingf · 2008
The article first revisits the debates on ICA(Immediate Constituent Analysis)and the traditional sentence analysis during the 1950s.It points out that both fail to provide a definite criterion for the limit of constituent segmentation.The paper emphasizes that the fundamental defect of ICA is that the notion of heads does not play any role therein.ICA only provides a set of binary structural patterns,but not the association patterns composed of various binary patterns.ICA also fails in representing the multi-valence semantic relations.A new method is then positted,namedDirect Constituent Analysis,which emphasizes the unique head-word and the orbit layer structure centered on the head-word.
