The work described in this report is the result of collaborative effort involving all contributors, as for all EAGLES work. Indications of individual contributions are given in the Contributors section: these indicate mainly which person was responsible for leading and summarising discussion.
The report is organised into five main chapters. Chapter 3 provides a review and comparison of different approaches to subcategorisation adopted in linguistic theories, practical NLP lexicons and bracketted corpora. In chapter 4, the results of the comparisons drawn in the preceding chapter are used to compile frame-based representations of subcategorisation structures. After a general description of the frame structure, specific details are given concerning the encoding of categorial and morphosyntactic properties, grammatical functions, order, verbal diatheses, control, thematic roles and semantic class. In chapter 5, a formalisation of the encoding scheme presented is given using an object-oriented specification written in SGML. In appendix (available only via ftp as a gzipped PostScript file), a set of macros is given which synthesises the formal frame descriptions presented in chapter 3; using these macros, a list of examples is compiled for each of the languages represented within the group.
