Systemic functional linguistics offers a grammar that is semantically organised, so that salient grammatical choices are made explicit. This paper describes the explication of these choices through the conversion of the Penn Treebank into a systemic functional grammar corpus. Developing such a resource can help connect work in natural language processing to a significant body of research dealin...

Language CoLLAGE is a collection of grammatical descriptions developed in the context of a grammar engineering graduate course with the LinGO Grammar Matrix. These grammatical descriptions include testsuites in well-formed interlinear glossed text (IGT) format, high-level grammatical characterizations called ‘choices files’, HPSG grammar fragments (capable of parsing and generation), and docume...

We investigate parsing replicability across 7 languages (and 8 treebanks), showing that choices concerning the use of grammatical functions in parsing or evaluation and the influence of the rare word threshold, as well as choices in test sentences and evaluation script options have considerable and often unexpected effects on parsing accuracies. All of those choices need to be carefully documen...

This study examines a variable-length Particle Swarm Algorithm for Social Programming. The Grammatical Swarm algorithm is a form of Social Programming as it uses Particle Swarm Optimisation, a social swarm algorithm, for the automatic generation of programs. This study extends earlier work on a fixed-length incarnation of Grammatical Swarm, where each individual particle represents choices of p...

Our focus in this chapter is on grammatical composition, the relation that holds (relative to a formal or cognitive system of grammatical analysis G) between the global properties associated with a linguistic entity and the correlative properties associated with its component parts. We first discuss why grammatical composition in this sense raises questions that deserve particular attention. We...

In natural language generation, the use of a lexicalized grammar formalism and incremental syntactic and semantic processing places strong and specific constraints on the form and meaning of grammatical entries. These principles restrict which grammatical representations are possible and suggest examples an analyst can consult to decide among possibilities. We discuss and justify a number of su...
