Simulated autopoiesis in liquid automata (2024)
Journal Article

We present a novel form of Liquid Automata, using this to simulate autopoiesis, whereby living machines self-organise in the physical realm. This simulation is based on an earlier Cellular Automaton described by Francisco Varela. The basis of Liquid... Read More about Simulated autopoiesis in liquid automata.

Artificial life as controlled disequilibrium (2023)
Presentation / Conference Contribution

Artificial Life can be modeled using simulated au-topoiesis. Liquid Automata are used to define simulated chemical reaction systems; particle systems with rules governing how particles are transformed on collision with each other. Unlike cellular aut...

Problem classification for tailored help desk auto replies (2022)
Presentation / Conference Contribution

IT helpdesks are charged with the task of responding quickly to user queries. To give the user confidence that their query matters, the helpdesk will auto-reply to the user with confirmation that their query has been received and logged. This auto-re...

Task-oriented dialogue systems: Performance vs. quality-optima, a review (2022)
Presentation / Conference Contribution

Task-oriented dialogue systems (TODS) are continuing to rise in popularity as various industries find ways to effectively harness their capabilities, saving both time and money. However, even state-of-the-art TODS are not yet reaching their full pote... Read More about Task-oriented dialogue systems: Performance vs. quality-optima, a review.

Inter-annotator agreement using the Conversation Analysis Modelling Schema, for dialogue (2022)
Journal Article

We present the Conversation Analysis Modeling Schema (CAMS), a novel dialogue labeling schema that combines the Conversation Analysis concept of Adjacency Pairs, with Dialogue Acts. The aim is to capture both the semantic and syntactic structure of d... Read More about Inter-annotator agreement using the Conversation Analysis Modelling Schema, for dialogue.

Sentence encoding for dialogue act classification (2021)
Journal Article

In this study, we investigate the process of generating single-sentence representations for the purpose of Dialogue Act (DA) classification, including several aspects of text pre-processing and input representation which are often overlooked or under... Read More about Sentence encoding for dialogue act classification.

The natural connectivity of autonomous systems (2020)
Journal Article

The principle of biological autonomy, introduced by Francisco J. Varela, addresses the dilemma of Cartesian mind-body dualism by re-casting mind and body, or subject and object, observer and observed, not as irreconcilable categories, but as compleme...

Investigating the feasibility of using wearable technologies and machine learning techniques to recognise distress and agitation in people living with dementia (2020)
Journal Article

The natural connectivity of autonomous systems (2019)
Presentation / Conference Contribution

The concept of enaction, or embodied cognition, de- scribed by Varela et al., aims to resolve the the dilemma of Cartesian mind-body dualism by re-casting these categories as complementary explanations of the same phenomena. This paper explores Varel... Read More about The natural connectivity of autonomous systems.

A smart contract model for agent societies (2018)
Presentation / Conference Contribution

This paper presents a solution to the exchange of services within an agent society. We explore an open delivery chain scenario in which autonomous drones offer and subcontract delivery services to each other. Such agents are able to self-organize acc...

Conversation analysis structured dialogue for multi-domain dialogue management (2018)
Presentation / Conference Contribution

Dialogue state tracking is a vital component of task-oriented dialogue systems. Often, dialogue states are constrained by their target domains entity's, slots and values. Adding new domains and knowledge may require laborious hand-crafting or retrain... Read More about Conversation analysis structured dialogue for multi-domain dialogue management.

Probabilistic word association for dialogue act classification with recurrent neural networks (2018)
Book Chapter

The identification of Dialogue Acts (DA) is an important aspect in determining the meaning of an utterance for many applications that require natural language understanding, and recent work using recurrent neural networks (RNN) has shown promising re...

Principles of robot autonomy (2018)
Presentation / Conference Contribution

This paper is an exploration of the theory of autonomy as set out by Francisco J. Varela in his groundbreaking book, “Principles of Biological Autonomy.” Varela argues that autonomy is an expression of a pervasive circularity, or indeed complete orga...

Second International Symposium, ALIA 2016, Birmingham, UK, June 14-15, 2016

A modal logic analysis of a line-following robot (2018)
Presentation / Conference Contribution

© Springer International Publishing AG, part of Springer Nature 2018. The behaviour of a reactive, line-following robot is analysed using modal logic. This provides an approach that is complementary to numerical simulation, allowing us to explore the... Read More about A modal logic analysis of a line-following robot.

Governing narrative events with tropes as institutional norms (2018)
Presentation / Conference Contribution

© Springer International Publishing AG, part of Springer Nature 2018. A narrative world can be viewed as a form of society in which characters follow a set of social norms whose collective function is to guide the characters through (the creation of)...

LoRaWAN Bristol (2017)
Presentation / Conference Contribution

The Bristol LoRaWAN Network is a low power radio network for the Internet of Things, based on LoRaWAN and utilising The Things Network. LoRaWAN is a Low Power Wide Area Network (LPWAN) specification intended for wireless battery operated Things in re... Read More about LoRaWAN Bristol.

Understanding learning strategy as conversation (2017)
Presentation / Conference Contribution

The goal of this research is to understand the learning strategies employed by students using so called Intelligent Tutoring Systems (ITS), with the aim of supporting efforts to improve the effectiveness of this type of educational technology. An exp... Read More about Understanding learning strategy as conversation.

A mobile homeostat with three degrees of freedom (2015)
Presentation / Conference Contribution

In the foundational cybernetics text, Design for a Brain, W. Ross Ashby introduces an adaptive system called the homeostat, and speculates about the possibility of creating a mobile homeostat “with its critical states set so that it seeks situations...
