Introduction

What’s XLE?

Xerox Linguistics EnvironmentA computational environment developed to facilitate the writing and debugging of Lexical Functional GrammarsC-structure, f-structure, s-structure, and further projections can be defined Includes other activities related to grammar development: analysing performance, test suites, generation, treebanks and other.

Assumptions

All four possible Modern Greek word orders (VSO, SVO, OSV and OVS) are equally acceptable and grammaticalModern Greek Word order is represented non-configurationally (Tzanidaki, 1996; Alexopoulou, 1999 among others) :

No morphology. For each word there is a separate lexical entry for each case, gender and number.

Demo Grammar

CoverageAll 4 word orders (ex.1-4)Pro-drop character of the language (empty string node e as a disjunction in the subject NP c-structure node) (ex.5-6)Subcategorization frames of intransitive, transitive and ditransitive verbs (including the realisation of the OBL object of ditransitive verbs either through an NP in GEN or a PP[se] (ex 7-10), successfully ruling out sentences like (11)successful assignment of the appropriate grammatical functions to constituents according to their case (NOMSUBJ, ACCOBJ, GENOBL) (ex.12) ruling out ex.13number, case and gender assignment among the constituents of an NP or a PP (ex.14-17)
