Reducing the Planning Horizon Through Reinforcement Learning
Planning is a computationally expensive process, which can limit the reactivity of autonomous agents. Planning problems are usually solved in isolation, independently of similar, previously solved problems. Th...

Contingent Scaffolding for System Safety Analysis
System safety analysis is a creative process that can often be undertaken by people who are not experts in the system under analysis whilst also learning the analysis methodology. With the increase of system ...

Qualitative and Quantitative Spatio-temporal Relations in Daily Living Activity Recognition
For the effective operation of intelligent assistive systems working in real-world human environments, it is important to be able to recognise human activities and their intentions. In this paper we propose a ...

RCC*-9 and CBM*
In this paper we introduce a new logical calculus of the Region Connection Calculus (RCC) family, RCC*-9. Based on nine topological relations, RCC*-9 is an extension of RCC-8 and models topological relations b...

Carried Object Detection and Tracking Using Geometric Shape Models and Spatio-temporal Consistency
This paper proposes a novel approach that detects and tracks carried objects by modelling the person-carried object relationship that is characteristic of the carry event. In order to detect a generic class of ca...

Egocentric Activity Monitoring and Recovery
This paper presents a novel approach for real-time egocentric activity recognition in which component atomic events are characterised in terms of binary relationships between parts of the body and manipulated ...

Workflow Activity Monitoring Using Dynamics of Pair-Wise Qualitative Spatial Relations
We present a method for real-time monitoring of workflows in a constrained environment. The monitoring system should not only be able to recognise the current step but also provide instructions about the possi...

Interleaved Inductive-Abductive Reasoning for Learning Complex Event Models
We propose an interleaved inductive-abductive model for reasoning about complex spatio-temporal narratives. Typed Inductive Logic Programming (Typed-ILP) is used as a basis for learning the domain theory by gener...

From Video to RCC8: Exploiting a Distance Based Semantics to Stabilise the Interpretation of Mereotopological Relations
Mereotopologies have traditionally been defined in terms of the intersection of point sets representing the regions in question. Whilst these semantic schemes work well for purely topological aspects, they do ...

Mining Video Data: Learning about Activities
In this talk I will present ongoing work at Leeds on building models of video activity. I will present techniques, both supervised and unsupervised, for learning the spatio-temporal structure of tasks and even...

Rabbit to OWL: Ontology Authoring with a CNL-Based Tool
Recent work on ontology engineering has seen the adoption of controlled natural languages to ease the process of ontology authoring. However, CNL-based tools still require good knowledge engineering skills to ...
