Mark Johnson
Once one has enriched LFG's formal machinery with the linear logic mechanisms needed for semantic interpretation as proposed by Dalrymple et. al., it is natural to ask whether thes…
The effect of alternative tree representations on tree bank grammars
Mark Johnson
The performance of PCFGs estimated from tree banks is sensitive to the particular way in which linguistic constructions are represented as trees in the tree bank. This paper presen…
Features as Resources in R-LFG
Mark Johnson
This paper introduces a non-unification-based version of LFG called R-LFG (Resource-based Lexical Functional Grammar), which combines elements from both LFG and Linear Logic. The p…
Proof Nets and the Complexity of Processing Center-Embedded Constructions
