Negation Focus Identification with Contextual Discourse Information
Negative expressions are common in natural language text and play a critical role in information extraction. However, the performances of current systems are far from satisfaction, largely due to its focus on intrasentence information and its failure to consider inter-sentence information. In this paper, we propose a graph model to enrich intrasentence features with inter-sentence features from...
متن کاملUGroningen: Negation detection with Discourse Representation Structures
We use the NLP toolchain that is used to construct the Groningen Meaning Bank to address the task of detecting negation cue and scope, as defined in the shared task “Resolving the Scope and Focus of Negation”. This toolchain applies the C&C tools for parsing, using the formalism of Combinatory Categorial Grammar, and applies Boxer to produce semantic representations in the form of Discourse Rep...
متن کاملImplicit Causality, Negation, and Models of Discourse
Causality plays an important role in giving discourse its characteristic coherence. This paper examines how causality implicit in an utterance helps to organize dynamically constructed mental models of discourse. Experiments are reported suggesting that the linguistic form of utterances contributes significant semantic information about causality to a discourse representation. This view is cont...
متن کاملIncrementing Discourse with the Negation Relation
Logical t ranslat ions of English sentences typically translate sentential negation as a unary propositional operator. In this paper, I develop the processing aspect of a rather different ontological perspective on negation: namely, negation as a two-place relation. The negation relation takes one argument, its associate, and relates it to the rest of the sentence which forms the second argumen...
متن کاملThe Basic Constructive Logic for Negation-Consistency
In this paper, consistency is understood in the standard way, i.e. as the absence of a contradiction. The basic constructive logic BKc4, which is adequate to this sense of consistency in the ternary relational semantics without a set of designated points, is defined. Then, it is shown how to define a series of logics by extending BKc4 up to minimal intuitionistic logic. All logics defined in th...
