Wide-coverage efficient statistical parsing with CCG and log-linear models
- COMPUTATIONAL LINGUISTICS
, 2007
"... This paper describes a number of log-linear parsing models for an automatically extracted lexicalized grammar. The models are "full" parsing models in the sense that probabilities are defined for complete parses, rather than for independent events derived by decomposing the parse tree. Dis ..."

. Discriminative training is used to estimate the models, which requires incorrect parses for each sentence in the training data as well as the correct parse. The lexicalized grammar formalism used is Combinatory Categorial Grammar (CCG), and the grammar is automatically extracted from CCGbank, a CCG version
Wide-Coverage CCG . . .
, 2010
"... This dissertation presents the development of a wide-coverage semantic parser capable of handling quantifier scope ambiguities with a novel way. In contrast with traditional approaches that deliver an underspecified representation and focus on enumerating the possible readings “offline ” after the e ..."

in first-order logic, using λ-calculus as a “glue ” language, in the tradition of Montague. We base our parser on the OpenCCG framework, and we augment it by applying a well-established supertagger and by developing a head-driven probabilistic model. Our model is trained on CCGbank, a CCG version
Evaluating a Wide-Coverage CCG Parser
- In Proceedings of the LREC Workshop on Beyond Parseval
, 2002
"... This paper compares three evaluation metrics for a CCG parser trained and tested on a CCG version of the Penn Treebank. The standard Parseval metrics can be applied to the output of this parser; however, these metrics are problematic for CCG, and a comparison with scores given for standard Penn Tree ..."

CCG-based models for statistical . . .
, 2009
"... The arguably best performing statistical machine translation systems are based on context-free formalisms or weakly equivalent ones. These models usually use a synchronous version of a context-free grammar (SCFG) which we argue is too rigid for the highly ambiguous task of human language translation ..."

Integrating Verb-Particle Constructions into CCG Parsing
"... Despite their prevalence in the English language, multiword expressions like verb-particle constructions (VPCs) are often poorly handled by NLP systems. This problem is partly due to inadequacies in existing corpora; the primary corpus for CCG-oriented work, CCGbank, does not account for VPCs at all ..."

A CCG-based Approach to Fine-Grained Sentiment Analysis in Microtext
"... In this paper, we present a Combinatory Categorial Grammar (CCG) based approach to the classification of emotion in microtext. We develop a method that makes use of the notion put forward by Ortony, Clore, and Collins (1988), that emotions are valenced reactions. This hypothesis sits central to our ..."

Information-structural semantics for English intonation

These accounts share the assumption that the system of tones identified by Pierrehumbert (1980), as modified by Pierrehumbert and Beckman (1988) and Silverman et al. (1992), h ..."

This grammar integrates intonation structure into surface derivational structure and the associated Montague-style compositional semantics
