Discourse coherence is strongly associated with text quality, making it important to natural language generation and understanding. Yet existing models of coherence focus on measuring individual aspects of coherence (lexical overlap, rhetorical structure, entity centering) in narrow domains. In this paper, we describe domainindependent neural models of discourse coherence that are capable of me...

This paper provides a computational characterization of coherence that applies to a wide range of philosophical problems and psychological phenomena. Maximizing coherence is a matter of maximizing satisfaction of a set of positive and negative constraints. After comparing five algorithms for maximizing coherence, we show how our characterization of coherence overcomes traditional philosophical ...

The principle and the applications of a recently proposed unconventional holography technique, called coherence holography, and a related technique for dispersion-free 3-D coherence imaging based on a spatial frequency comb will be reviewed. ©2007 Optical Society of America OCIS codes: (090.0090) Holography; (030.1640) Coherence; (100.3010) Image reconstruction techniques; (110.4500) Optical co...

This study focuses on modeling discourse coherence in the context of automated assessment of spontaneous speech from non-native speakers. Discourse coherence has always been used as a key metric in human scoring rubrics for various assessments of spoken language. However, very little research has been done to assess a speaker's coherence in automated speech scoring systems. To address this, we ...

In this paper we study how agents can autonomously deliberate on norms and cognitions in the context of a normative multiagent system. We propose Thagard’s cognitive theory of coherence as a tool to achieve this autonomous deliberation. Taking a proof-theoretic approach, we first provide a formalization of coherence theory, focusing on a particular type of coherence, namely deductive coherence....

Abnormal functional brain connectivity is a candidate factor in developmental brain disorders associated with cognitive dysfunction. We analyzed a substantial (10 min per subject) record of dense array electroencephalography with spectral power and coherence methods in attention-deficit hyperactivity disorder (ADHD) (n = 42) and control (n = 21) 10- to 13-year-old children. We found topographic...

PURPOSE Corticomuscular electroencephalographic-electromyographic (EEG-EMG) coherence elicited by speech and nonspeech oromotor tasks in healthy participants and those with Parkinson's disease (PD) was examined. Hypotheses were the following: (a) corticomuscular coherence is demonstrable between orbicularis oris (OO) muscles' EMG and scalp EEG recording; (b) the presence, location, and magnitud...

Measuring the coherence of writing using topic-based analysis Abstract Among the many possible aspects to assess in writing, one of the most problematic is coherence. The problems with marking coherence arise because it is by nature subjective. However, the reasonable probability of several readers reaching a consensus concerning the coherence of a text suggests that it may be possible to assig...

BACKGROUND The GRADE-CERQual (Grading of Recommendations Assessment, Development and Evaluation-Confidence in Evidence from Reviews of Qualitative research) approach has been developed by the GRADE working group. The approach has been developed to support the use of findings from qualitative evidence syntheses in decision-making, including guideline development and policy formulation. CERQual i...

BACKGROUND Neuroplasticity drives recovery of walking after a lesion of the descending tract. Intramuscular coherence analysis provides a way to quantify corticomotor drive during a functional task, like walking and changes in coherence serve as a marker for neuroplasticity. Although intramuscular coherence analysis is already applied and rapidly growing in interest, the reproducibility of vari...
