We report a Japanese parsing system with a linguistically fine-grained grammar based on the Lexical-Functional Grammar (LFG) formalism. The system is the first Japanese LFG parser with over 97% coverage for real-world text. We evaluated the accuracy of the system comparing it with standard Japanese dependency parsers. The LFG parser shows roughly equivalent performance on the dependency accurac...

A nested datatype, also known as a non-regular datatype, is a parametrised datatype whose declaration involves different instances of the accompanying type parameters. Nested datatypes have been mostly ignored in functional programming until recently, but they are turning out to be both theoretically important and useful in practice. The aim of this paper is to suggest a functorial semantics fo...

The nature of mathematical language and the linguistic challenges of learning mathematics have been explored since the 1970s. Schleppegrell (2007) provides a comprehensive synthesis of the research completed by applied linguistics and mathematics educators which aims to identify the linguistic structures in mathematics and how these differ from everyday language. In particular, Michael Halliday...

the category of verb as the nucleus of sentence has a significant importance in grammar. this grammatical category has specific semantic and syntactic characteristics in different languages. in role and reference grammar as a functional grammar, predicates are classified into five classes including states, activities, achievements, accomplishments and active-accomplishments. these five classes ...

In addition, the project has entered into two collaborations that show great promise. The KOMET project at the IPSI Insti tute in West Germany (funded by the German Federal Government) is a new project with goals very similar to our own. In addition to funding some of our work, they are building a systemic grammar of German and are collaborating on our parsing research. The Department of Lingui...

We describe a method for interpreting abstract fiat syntactic representations, LFG f-structures, as underspecified semantic representations , here Underspecified Discourse Representation Structures (UDRSs). The method establishes a one-to-one correspondence between subsets of the LFG and UDRS formalisms. It provides a model theoretic interpretation and an inferen-tial component which operates d...

This paper defends the thesis that in German all sentential arguments occurring in sentenceinitial position have undergone obligatory left dislocation. This implies that the Vorfeld is unable to be occupied by sentential arguments. The resumptive pronoun that immediately follows the left-dislocated phrase may be deleted in accordance with the conditions on Topic Drop that hold for German (cf. O...
