In this paper, we present and evaluate an approach to incremental dialogue act (DA) segmentation and classification. Our approach utilizes prosodic, lexico-syntactic and contextual features, and achieves an encouraging level of performance in offline corpus-based evaluation as well as in simulated human-agent dialogues. Our approach uses a pipeline of sequential processing steps, and we investi...

How can the classical psychological laws be explained and unified? It is proposed here that scale-invariance is a unifying principle. Distributions of many environmental magnitudes are observed to be scale invariant; that is, the statistical structure of the world remains the same at different measurement scales [Mandelbrot, B., 1982. The Fractal Geometry of Nature (2nd Edn.). W.H. Freeman, San...

We present a novel synthesis method for procedural generation of complex curves. Our approach takes a simple example input curve specified by a user and automatically generates complex curves that resembles the input. The algorithm preserves many of the input shape features such as tangent directions, curvature and branch nodes. The overall system is simple and can be used to generate different...

The art world changed forever when Jackson Pollock picked up a can and poured paint onto a vast canvas rolled across the floor of his windswept barn. Fifty years on, art theorists recognize his patterns as being a revolutionary approach to aesthetics. A significant step forward in understanding Pollock’s aesthetics occurred in 1999 when my scientific analysis showed that his paintings are fract...

This paper presents a new framework for asynchrony. This has its origins in our attempts to better harness the internal decision-making process of cellular automata (CA). Thus, we show that a max-plus algebraic model of asynchrony arises naturally from the CA requirement that a cell receive the state of each neighbor before updating. The significant result is the existence of a bijective mappin...

The study pertains to the economic issues of risk and uncertainties associated with financing hill agriculture from the twin angles of risk of farmers to utilize the credit and of bankers to disburse the agricultural loan. The issues discussed are: first, why the financial institutions are reluctant to lend agricultural advances? Second, whether the farm income or rate of return on equity and n...

It is widely recognised that microhabitats are important for a variety of marine organisms, yet this knowledge has rarely been applied in the construction of engineered structures as a means of enhancing biodiversity or populations of species at risk. Here we examined the influence of microhabitats on the distribution and survival of the exploited limpet Patella candei on natural shores before ...

The growing demanding from consumers for healthier foods, produced using environmentally friendly farming practices has resulted in the rapid expansion of organic farming. There are numerous studies about the importance of organic farming but the majority of the results are sometimes contradictory, inconsistent and show no clear link between organic farming practices and enhancement of the nutr...
