Abstract
We describe a principled method for representing documents by phrases abstracted into Head/Modifier pairs. First the notion of aboutness and the characterization of full-text documents by HM pairs is didcussed. Based on linguistic arguments, a taxonomy of HM pairs is derived. We briefly describe the EP4IR parser/transducer of English and present some statistics of the distribution of HM pairs in newspaper text. Based on the HM pairs generated, a new technique to measure the accuracy of a parser is introduced, and applied to the EP4IR grammar of English. Finally we discuss the merits of HM pairs and HM trees as a document representation. © Springer-Verlag 2004.
