In this paper, we present the JUCSE system, designed for the TempEval-3 shared task. The system extracts events and temporal information from natural text in English. We have participated in all the tasks of TempEval-3, namely Task A, Task B & Task C. We have primarily utilized the Conditional Random Field (CRF) based machine learning technique, for all the above tasks. Our system seems to perf...

There is an extensive literature on task modelling related to the design of computer systems. Task analysis and task modelling have been widely recognized as central components in human-centred approaches. The aim of this paper is to report on some results of a worldwide survey about actual practices of task descriptions languages (TDL) in SIGCHI community. Results suggest that academic TDL are...

The intent of this research is to study the interacting effect of culture and task nature on the adoption of communication media tools. The objectives are to suggest a comprehensive approach to the study of business communication media adoption with the consideration of cultural and task nature impact and to identify the best match of cultural characteristics and task nature with media choices ...

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...
