Linguistic Resources

In an ideal world, computational semanticists would not have to worry overly much about linguistic resources. Large scale lexica, treebanks, and wide coverage grammars (supported by fast parsers and offering a flexible syntax semantics interface) would be freely available and easy to combine and use. The semanticist could then focus on modelling semantic phenomena and their interactions.

Needless to say, in reality matters are not nearly so straightforward. For a start, for many languages (including French) there are no large-scale resources of the sort that exist for English. Furthermore even in the case of English, the idealised situation just sketched does not obtain. For example, the syntax/semantics interface cannot be regarded as a solved problem: phenomena such as gapping still offer challenging problems for semantic construction.

Thus a team like LED simply cannot focus exclusively on semantic issues: it must also have competence in developing and maintaining a number of different lexical resources (and in particular, resources for French).

LED is involved in such aspects in a number of ways. For example, it participates in the development of an open source morpho syntactic lexicon for French, in an attempt to lay the ground for a French version of FrameNet; it collaborates with the development of a metagrammar compiler for Tree Adjoining Grammars, TAG, (to enable the construction of a wide coverage grammar for French); and, more recently, it is involved in the development of a Lexical Functional Grammar, LFG, and a Head-Driven Phrase Structure Grammar, HPSG, (both offering a syntax/semantics interface) for French.
