Web browser users return to Web pages for various reasons. Apart from pages visited due to backtracking, they typically have a number of favorite/important pages that they monitor or tasks that reoccur on an infrequent basis. In this paper, we introduce the architecture of a system that facilitates revisitations through the effective prediction of the next page request. It consists of three lay...

We present evidence for the importance of low-level phenomena in dialogue interaction and use this to motivate a multi-layered approach to dialogue processing. We describe an architecture that separates content-level communicative processes from interaction-level phenomena (such as feedback, grounding, turn-management), and provide details of specific implementations of a number of such phenomena.

We propose a novel three-layered approach for semantic segmentation of building facades. In the first layer, starting from an oversegmentation of a facade, we employ the recently introduced machine learning technique Recursive Neural Networks (RNN) to obtain a probabilistic interpretation of each segment. In the second layer, initial labeling is augmented with the information coming from specia...

We propose a framework for extracting structure from stereo which represents the scene as a collection of approximately planar layers. Each layer consists of an explicit 3D plane equation, a colored image with per-pixel opacity (a sprite), and a per-pixel depth offset relative to the plane. Initial estimates of the layers are recovered using techniques taken from parametric motion estimation. T...

The integration of digital components into clothing is becoming an increasingly important segment in wearable computing research. The first indications for this trend are the incorporation of existing mobile technologies, such as personal digital assistants (PDAs) or mobile phones, into jackets via flexible textile circuits. In the long term, other components could also be envisioned that are e...

This paper discusses the stackable layers approach to le system design. With this approach, a le system is constructed from several layers, each implementing one portion of the le system well. Each layer is bounded above and below by an identical interface framework. The symmetry of the interface, coupled with run-time stack deenition, make layer conngura-tion exible and facilitate experimentat...

Although the notion of conversations has been discussed for some time as a way in which to provide an abstract representation of extended agent message exchange, there is still no consensus established concerning how to use these abstractions effectively. This paper describes a layered approach based on coloured Petri Nets that can be used for modelling complex, concurrent conversations among a...

Since electronic commerce transaction are characterised by their highly communicative character, the Language-Action-perspective proves to be very suitable to provide a deep-structure analysis because it concentrates on the essential aspects of an electronic commerce transaction rather than the form. In this paper, we present a layered pattern definition language, based on various L/A-perspecti...

In this paper, we present a layered agent framework in which the negotiation process is performed at different levels of abstractions. In a real time, multiple-tasking, resource-bounded environment, negotiation is not an isolated process but one that interleaved with agent’s many other activities, such as scheduling, execution, and other negotiations. To make the complexities of negotiation mor...
