The PolySyn project is an ESRC funded project. The principal investigator and research fellow is Lynne Cahill.
The aim of the project is to add syntactic subcategorisation information to the PolyLex lexicons.
One of the most fundamental kinds of information required by NLP lexicons is the syntactic subcategorisation of verbs and, to a lesser extent, nouns. The PolySyn project took the results of two previous projects and combine them to maximum effect.
The first project is the PolyLex project, which developed highly structured lexicons of closely related languages, concentrating on aspects of lexical knowledge that are particularly similar in related languages, namely phonology, morphology and orthography.
The other is the GREG project, which developed a cross-linguistic approach to syntactic subcategorisation and semantic roles (valency) in relatively unrelated languages, namely English, German, Georgian and Russian.
The primary aim of the PolyLex project was to exploit the similarities of closely related languages. In this project the techniques developed in that project will be taken one step further, to show that the techniques can also be usefully employed for certain aspects of the lexical knowledge required for unrelated languages. The idea behind this is that, while phonological, morphological and orthographic information is only likely to be significantly similar in closely related languages, syntactic subcategorisation information is likely to be much more similar, as it is inherently related to the number of semantic arguments.
The project is a follow-on to the POLYORTH project, undertaken at the University of Sussex by Lynne Cahill, Carole Tiberius and Jon Herring. More information and resources from this project can be found here.
The full PolyLex lexicons with syntactic information added will be available
here shortly (after some reorganisation of the phonological, morphological and
orthographic information). In the meantime reduced versions of the lexicons
with just the syntactic subcategorisation information are available
here.
