We outline the challenges and opportunities presented by constraint solving in the presence of change and uncertainty, embodied in CALO's personalized time management and task reasoning and execution systems.

This paper presents ongoing work to build the Personalized Time Manager (PTIME) system, a persistent assistant that builds on our previous work on a personalized calendar agent (PCalM) (Berry et…

We describe an approach that tracks planar regions of scene text that can undergo arbitrary 3-D rigid motion and scale changes. Our approach computes homographies on blocks of contiguous frames…

We use the Sequitur algorithm to generate a context-free grammar which efficiently extracts repetitive sequences of commands executed by one user – which is mainly used to generate a profile of the…

This paper presents a new human-motion identification and segmentation algorithm from moving cameras. The algorithm is based on alignment error between pairs of moving object images. Pairs of object images…

This paper explores the mixed-initiative issues arising in the Personalized Time Manager (PTIME) system. PTIME is a persistent assistant that builds on our previous work on a personalized calendar agent.

In this paper, we report on a process language, PPL, that we have designed to serve as a bridge between a representation designed for execution and a representation designed for…

This paper presents ongoing work to build the Personalized Time Manager (PTIME) system, a persistent assistant that builds on our previous work on a personalized calendar agent.

This paper reports the results of an experimental analysis of higher-order constructs in graphical patterns and their effect on pattern matching efficiency.
