Traditionally, linguistic variation within different time scales has been the province of different disciplines, each with a distinctive suite of techniques for obtaining and analyzing data. For example, historical linguistics, sociolinguistics and corpus linguistics study variation between differen ...

Minimum-error-rate training (MERT) is a bottleneck for current development in statistical machine translation (MT) because it has difficulty estimating more than a dozen or two parameters. I will present two classes of features that address deficiencies in the Hiero hierarchical phrase-based transla ...

computer science;machine learning;kernel methods
Kernel methods are widely used in statistical learning techniques due to their excellent performance and their computational efficiency in high-dimensional feature space. However, text or speech data cannot always be represented by the fixed-length vectors that the traditional kernels handle. In thi ...

The relationship between grammar and language behavior is not entirely clear-cut. One classic view (Chomsky 65, Bresnan & Kaplan 82, Stabler 83, Steedman 89) holds that grammars specify a time-independent body of knowledge, one that is deployed on-line by a processing mechanism. Determining the comp ...

This talk will discuss production and perception studies of deceptive speech and the acoustic/prosodic and lexical cues associated with deception. Experiments in which we collected a large corpus of deceptive and non-deceptive speech from naive subjects in the laboratory are described, together with ...

Can we create a system that can learn to understand political speeches well enough to determine the speakers' viewpoints? Can we improve information retrieval by using link analysis, as is famously done in Web search, if we are dealing with documents that don't contain hyperlinks? And how can these ...

Spoken language technologies, such as automatic speech recognition and synthesis, typically treat speech as a string of "phones". In contrast, humans produce speech through a complex combination of semi-independent articulatory trajectories. Recent theories of phonology acknowledge this, and treat s ...

As we scale statistical machine translation systems to general domain, we face many challenges. This talk outlines two approaches for building better broad-domain systems.
First, progress in data-driven translation is limited by the availability of parallel data. A promising strategy for mitigating ...
