A model for the generation of fundamental frequency contours (F0contours) of spoken, sentences is presented for the purpose of elucidating the relationship between the sentence F0 contour and the linguistic and non-linguistic information. It is based on a quantitative formulation of the process whereby the logarithmic fundamental frequency is controlled in proportion to the sum of two component...

BACKGROUND Although memory impairment is the main symptom of Alzheimer's disease (AD), language impairment can be an important marker. Relatively few studies of language in AD quantify the impairments in connected speech using computational techniques. OBJECTIVE We aim to demonstrate state-of-the-art accuracy in automatically identifying Alzheimer's disease from short narrative samples elicit...

Most theories of coreference specify linguistic factors that modulate antecedent accessibility in memory; however, whether non-linguistic factors also affect coreferential access is unknown. Here we examined the impact of a non-linguistic generation task (letter transposition) on the repeated-name penalty, a processing difficulty observed when coreferential repeated names refer to syntactically...

Language change results from the differential propagation of linguistic variants distributed among the linguistic repertoires of communicatively interacting individuals in a given community. From this it follows that language change is socially-mediated in two important ways. First, since language change is a social-epidemiological process that takes place by propagating some aspect of communic...

Multivariate genetic analysis was used to examine the genetic and environmental aetiology of the interrelationships of diverse linguistic skills. This study used data from a large sample of 4 1/2-year-old twins who were tested on measures assessing articulation, phonology, grammar, vocabulary, and verbal memory. Phenotypic analysis suggested two latent factors: articulation (2 measures) and gen...

In a previous report we used the Linked Dipole Chain model unintegrated gluon densities to investigate the uncertainties in the predictions for central exclusive production of scalars at hadron colliders. Here we expand this investigation by also looking at other parameterizations of the unintegrated gluon density, and look in more detail on the behavior of these at small k⊥. We confirm our con...

Seeing others is a central metaphor in James Cameron’s film Avatar, used as a means to express empathy and empathic bonding throughout the film, both between humans and the Na’vi, and between the Na’vi and the animals that inhabit their world. Empathy entails an ability to see and feel the world from another’s perspective—feeling with rather than feeling for. Jake Sully’s shifting and boundary-...

This paper describes ongoing efforts at Linguistic Data Consortium to create shared evaluation resources for improved speech-to-text technology. The DARPA EARS Program (Effective, Affordable, Reusable Speech-to-Text) is focused on enabling core STT technology to produce rich, highly accurate output in a range of languages and speaking styles. The aggressive EARS program goals motivate new appro...

In this position paper we discuss some of the experiences we made in describing lexical data using representation formalisms that are compatible for the publication of such data in the Linked Data framework. While we see a huge potential in the emerging Linguistic Linked Open Data, also supporting the publication of less-resourced language data on the same platform as for mainstream languages, ...

Multimodel approaches are widely used with linear submodels, but border areas around submodels are problematic. Special cases of fuzzy linguistic equation models, which can be understood as linguistic Takagi-Sugeno (LTS) type fuzzy models, can be used to solve these problems in many cases. These models use a special nonlinear scaling approach for both inputs and outputs. The LTS models are robu...
