From Lexical Functional Grammar to enhanced Universal Dependencies

Estonian Dependency Treebank: from Constraint Grammar tagset to Universal Dependencies

This paper presents the first version of Estonian Universal Dependencies Treebank which has been semi-automatically acquired from Estonian Dependency Treebank and comprises ca 400,000 words (ca 30,000 sentences) representing the genres of fiction, newspapers and scientific writing. Article analyses the differences between two annotation schemes and the conversion procedure to Universal Dependen...

Lexical Functional Grammar

Lexical Functional Grammar (LFG) is a linguistic theory which studies the various aspects of linguistic structure and the relations between them. Traditional LFG analyses focus on two syntactic structures. Constituent structure (cstructure) represents word order and phrasal groupings, and functional structure (f-structure) represents grammatical functions like subject and object. These structur...

Lexical Functional Grammar

The term Lexical Functional Grammar (LFG) first appeared in print in the 1982 volume edited by Joan Bresnan: The Mental Representation of Grammatical Relations, the culmination of many years of research. LFG differs from both transformational grammar and relational grammar in assuming a single level of syntactic structure. LFG rejects syntactic movement of constituents as the mechanism by which...

Long-Distance Dependencies and Applicative Universal Grammar

To deal with long-distance dependencies, Applicative Universal Grammar (AUG) proposes a new type of categorial rides, called superposition rules. We compare the AUG rules with the alternative rules of Steedman's Combinatery Categorial Grammar (CCG) (Steedman, 1987, 1988, 1990; Szabolcsi, 1987; Ades and Steedman, 1982). In contrast to Steedtmm's rules, the AUG rules are free from inconsistencies...
