We present a novel technique for motion-based recognition of individual gaits in monocular sequences. Recent work has suggested that the image self-similarity plot of a moving person/object is a projection of its planar dynamics. Hence we expect that these plots encode much information about gait…
We describe the treatment of questions (Question-Answer Typology, question parsing, and results) in the Weblcopedia question answering system.
This paper describes a Bayesian approach for modeling 3D scenes as collection of approximately planar layers that are arbitrarily positioned and oriented in the scene. In contrast to much of the previous work on layer-based motion modeling, which computes layered descriptions of 2D image motion,…

In this paper we describe the Webclopedia, a system that uses a classification of QA types to facilitate coverage, uses a robust syntactic-semantic parser to perform the analysis, and contains a matcher that combines word- and parse-tree-level information to identify answer passages. Section 2 outlines…
We describe how 3D affine measurements may be computed from a single perspective view of a scene given only minimal geometric information determined from the image. This minimal information is typically the vanishing line of a reference plane, and a vanishing point for a direction…
In order to produce a good summary, one has to identify the most relevant portions of a given text. We describe in this paper a method for automatically training topic signatures{sets of related words, with associated weights, organized around head topics{and illustrate with signatures we…
The goal of the MuST [1] project is to develop a prototype system to facilitate not only retrieving documents from multilingual collections, but also to summarize and translate the retrieved document into the user’s preferred language. We focus on the integration of state-of-the-art technologies, try…
In this paper we describe the design and implementation of MuST, a multilingual information retrieval, summarization, and translation system. MuST integrates machine translation and other text processing services to enable users to perform cross-language information retrieval using available search services such as commercial Internet search…
We present methods for creating 3D graphical models of scenes from a limited numbers of images, i.e. one or two, in situations where no scene co-ordinate measurements are available. The methods employ constraints available from geometric relationships that are common in architectural scenes - such…
We describe how 3D affine measurements may be computed from a single perspective view of a scene given only minimal geometric information determined from the image. This minimal information is typically the vanishing line of a reference plane and a vanishing point for a direction…
In this tutorial, we review the state of the art in automatic text summarization, and discuss and critically evaluate current approaches to the problem. The tutorial is structured as follows: The need for text summarization. What is a summary, exactly? What types are there? We…
