A Machine-Understandable Ontology For Representing The Domain Knowledge Specific To Non-Pharmacological Treatment Of Behavioural And Psychological Symptoms Of Dementia, Zhenyu Zhang

University of Wollongong Thesis Collection 2017+

Dementia is a clinical syndrome characterised by a progressive deterioration in cognitive function beyond the usual consequences of biological ageing. It is common among older people, and significantly affects people’s memory, behaviour, and ability to perform activities of daily living, leading to a reduced quality of life and high dependency on others for care. Due to the lack of clear pathophysiology or cure, the focus of dementia care remains on supporting people to live well with the condition. One of the main challenges in dementia care is managing behavioural and psychological symptoms of dementia (BPSD), which are non-cognitive symptoms or …

Developing An Ontology For Representing The Domain Knowledge Specific To Non-Pharmacological Treatment For Agitation In Dementia, Zhenyu Zhang, Ping Yu, H.C. Chang, S K. Lau, Cui Tao, Ning Wang, Mengyang Yin, Chao Deng

Faculty of Engineering and Information Sciences - Papers: Part B

Introduction: A large volume of clinical care data has been generated for managing agitation in dementia. However, the valuable information in these data has not been used effectively to generate insights for improving the quality of care. Application of artificial intelligence technologies offers us enormous opportunities to reuse these data. For health data science to achieve this, this study focuses on using ontology to coding clinical knowledge for non-pharmacological treatment of agitation in a machine-readable format. Methods: The resultant ontology—Dementia-Related Agitation Non-Pharmacological Treatment Ontology (DRANPTO)—was developed using a method adopted from the NeOn methodology. Results: DRANPTO consisted of 569 concepts …

An Ontology Based Context-Aware Architecture For Smart Campus Applications, Nicolas R. Verstaevel, Guillaume Garzone, Thierry Monteil, Nawal Guermouche, Johan Barthelemy, Pascal Perez

SMART Infrastructure Facility - Papers

With an estimated number of more than 15 billion, objects, the management of architectures for the Internet of Things is a veritable challenge. The inherent mobility (in terms of devices and users) of the IoT means that the architecture has to be resilient to appearance and disappearance of devices. In this paper, we address the problem of autonomic management of IoT architecture by the means of ontologies. The problem we address is that given a dynamic system which is built upon a multitude of entities abstracted as services and characterized by their inputs and outputs, evolving targets that aim to …

Elegy: Counting Up My Dead (For Sandra Burr), Jen Webb

Animal Studies Journal

The loss of a loved one often forces the bereaved to question their philosophical frameworks, their ontology and epistemology foundations, and their own mortality. Following the recent and sudden death of Sandra Burr, my dear friend and valued colleague, I have been going through this same sad process. But the hard work of mourning is to some extent eased by time spent thinking about and reading through millennia of writings on being, death and grieving. The many thoughtful works by many fine writers provide vivid reminders that no matter who we might be, or in what context we live, the …

Emerging Of Academic Information Search System With Ontology-Based Approach, Norasykin Mohd Zaid, Sim Kim Lau

Faculty of Engineering and Information Sciences - Papers: Part A

This paper describes the comparison of ontology development tools for development of academic information search system that assists inexperienced research students at a local university in Malaysia to search for academic resources in the local language context (Bahasa Malaysia). The cohort of inexperienced research students faces two main problems when using current system comprises of keyword search. Firstly the language barrier-limiting students' capabilities to conduct keyword search in foreign language (such as English). Secondly limited research experience in querying often results in obtaining irrelevant search results. The proposed semantic search system aims to apply ontology-based search to overcome the above …

A Revised Attack On Computational Ontology, Nir Fresco, Phillip J. Staines

Faculty of Engineering and Information Sciences - Papers: Part A

There has been an ongoing conflict regarding whether reality is fundamentally digital or analogue. Recently, Floridi has argued that this dichotomy is misapplied. For any attempt to analyse noumenal reality independently of any level of abstraction at which the analysis is conducted is mistaken. In the pars destruens of this paper, we argue that Floridi does not establish that it is only levels of abstraction that are analogue or digital, rather than noumenal reality. In the pars construens of this paper, we reject a classification of noumenal reality as a deterministic discrete computational system. We show, based on considerations from …

Ontology-Based Knowledge Discovery From Unstructured And Semi-Structured Text, Jantima Polpinij

University of Wollongong Thesis Collection 1954-2016

This dissertation proposes a novel methodology for knowledge discovery in large data sets, with a focus on unstructured and semi-structured textual data. To our knowledge, extracting knowledge from unstructured and semi-structured textual data is a major unsolved problem in the area of knowledge discovery in databases (KDD). The problem becomes particularly acute due to ambiguity and lexical variations in natural language. This thesis seeks to address these problems. Firstly, it proposes a unified methodology, called the Ontologybased Knowledge Discovery in unstructured and semi-structured Text (On-KDT) methodology, to discover knowledge from unstructured/semi-structured texts. This approach leverages semantic information encoded in ontologies …

Aligning Ontology-Based Development With Service Oriented Systems, Jun Shen, Ghassan Beydoun, Graham Low, Lijuan Wang

Faculty of Engineering and Information Sciences - Papers: Part A

This paper argues for placing ontologies at the centre of the software development life cycle for distributed component-based systems and, in particular, for service-oriented systems. It presents an ontology-based development process which relies on three levels of abstraction using ontologies: architecture layer, application layer and domain layer. The paper discusses the key roles of ontologies with respect to the various abstraction layers and their corresponding impact on the concomitant workproducts. In addition, a peer-to-peer-based service selecting and composing tool is suggested as a way of supporting the process. The paper presents the architecture of the proposed tool and illustrates the …

Developing A Tool For Crowd-Sourced Verification Of A Radiation Oncology Ontology: A Summer Project, Joshua Pratt, Vishal Pandian, Evan Morrison, Andrew Alexis Miller

Faculty of Engineering and Information Sciences - Papers: Part A

We have been unable to nd a verifi ed, published Radiation Oncology Ontology. We undertook the process of verifying a Radiation Oncology Ontology with a mixture of crowd-sourcing and expert-based approaches to verify relationships in the ontology. We used a natural language based approach to portray concepts and relationships, surveying users to assess the relationships between concepts in the Radiation Oncology ontology. The work used a description of a patient's history expressed in XML.The natural language statements relating concepts are available on a website for veri cation, and readers are invited to complete the survey at http://coi-hs-survey.appspot.com/ to contribute.

Ontology-Based Search System Using Hierarchical Structure Design, Norasykin Mohd Zaid, Sim Kim Lau, Mohd Nihra Haruzuan Mohamad Said

Faculty of Engineering and Information Sciences - Papers: Part A

Major retrieval issues on conventional online database search systems faced by novice researchers are identified and described. An ontology-based search framework is proposed. The framework consists of five elements: (1) user, (2) query, (3) query interface, (4) search process, and (5) result. The query interface is designed based on the ontology hierarchical structure in the ontology datastore and is represented as keywords/sub-keywords structures in the query interface. Ontology enables relationships between keywords and terms to be defined. Ontology allows desired information to be retrieved by sharing common vocabularies with an understanding of meaning of terms in the domain. A prototype …

Who Are Our Nomad’S Today? Deleuze’S Political Ontology And The Revolutionary Problematic, Craig A. Lundy

Faculty of Law, Humanities and the Arts - Papers (Archive)

This paper will address the question of the revolution in Gilles Deleuze's political ontology. More specifically, it will explore what kind of person Deleuze believes is capable of bringing about genuine and practical transformation. Contrary to the belief that a Deleuzian programme for change centres on the facilitation of 'absolute deterritorialisation' and pure 'lines of flight', I will demonstrate how Deleuze in fact advocates a more cautious and incremental if not conservative practice that promotes the ethic of prudence. This will be achieved in part through a critical analysis of the dualistic premises upon which much Deleuzian political philosophy is …

Towards An Ontology-Based Knowledge Management: An Ontology Mediation Framework To Reconcile Inter-Organizational Knowledge, Nelson K. Y Leung

University of Wollongong Thesis Collection 1954-2016

Knowledge enables organizations to utilize and develop resources, enhance their competitiveness and develop sustainable competitive advantage. Knowledge management aims to manage and capitalize on knowledge by organizing formal and direct process to manage organizational knowledge in the workplace. Literature has shown that a number of knowledge management approaches have been developed with the purpose of managing organizational knowledge. However, these designs only focus on managing intra-organizational knowledge which is inadequate in the current business environment because users often require to access interorganizational knowledge from other knowledge sources in order to complete tasks in current knowledge explosion era. Furthermore, current knowledge …

An Ontology Development Methodology To Integrate Existing Ontologies In An Ontology Development Process, Nelson K. Y Leung, Sim Kim Lau, Nicole Tsang

Faculty of Engineering and Information Sciences - Papers: Part A

Ontology is defmed as an explicit specification of a conceptualization while a conceptualization is an abstract, simplified view of the world that we wish to represent for some purpose. To build high quality ontologies, developers are required to choose and follow a suitable ontology development methodology in which containing a series of steps, activities and guidelines that are put together in an organized and systematic manner. Literatures show that building ontologies by reusing existing ontologies is more cost effective than building from scratch. However, majority of the methodologies only provide a very limited discussion about how to perform integration or …

Use Of Ontologies For Validating Mas Analysis Models, Antonio Alejandro Lopez Lorca

University of Wollongong Thesis Collection 1954-2016

Ontologies, as a knowledge representation tool, rely on formal descriptions of semantics. They have often been used in software development to support various activities and generally improve the value of the systems produced. However, their use during requirements engineering activities to validate that the product being developed complies with the client’s conceptualisation is largely unexplored. In the field of Agent Oriented Software Engineering (AOSE), a few of the extant methodologies contemplate the use of ontologies but only for modelling the domain problem to support agent communication. Due to the complexity of Multi Agent Systems (MAS), errors in modelling activities during …

The cohort of inexperienced research students face problems of limited research experience in conducting search queries, which often result in obtaining irrelevant search results. Other problems encountered by novice researchers include having difficulty in using the right keyword to search; not having any research ideas when conducting searches; irrelevant results returned; and the need to make multiple queries in a multi-language context. Advancements in the Semantic Web and ontology presents an opportunity to help novice researchers in …

Developing An Ontology For Radiation Oncology, Andrew Alexis Miller

University of Wollongong Thesis Collection 1954-2016

The development of medical knowledge has always proceeded along pathways that relate to questions arising from expert domain specialty knowledge, practice and work flow. While medical knowledge advances as a whole, there are independent and specific knowledge streams for each specialty.

Radiation Oncology is a specialty domain, therefore one can expect that its ontology will reflect and be defined by its clinical terms and clinical work ow which are both specific and interconnected.

The assertion of this thesis is that this particular medical domain specialty demonstrates clearly that knowledge derived in the clinical management of a patient, the processes used …

Reflecting On Ontologies Towards Ontology-Based Agent-Oriented Software Engineering, Ghassan Beydoun, Brian Henderson-Sellers, Jun Shen, G. Low

Faculty of Informatics - Papers (Archive)

“Ontology” in association with “software engineering” is becoming commonplace. This paper argues for the need to place ontologies at the centre of the software development lifecycle for multi agent systems to enhance reuse of software workproducts as well as to unify agent-based software engineering knowledge. The paper bridges the state-of-the-art of ontologies research from Knowledge Engineering (KE) within Artificial Intelligence and Metamodelling within Software Engineering (SE). It presents a sketch of an ontology-based Multi Agent System (MAS) methodology discussing key roles on ontologies and their impact of workproducts, illustrating these in a MAS software development project for an important application …

Enhancing The Reusability Of Inter-Organizational Knowledge: An Ontology-Based Collaborative Knowledge Management Network, Joshua P. Fan, Nelson K Y Leung, Sim K. Lau

Sydney Business School - Papers

Researchers have developed various knowledge management approaches that only focus on managing organizational knowledge. These approaches are developed in accordance with organizational KM strategies and business requirements without the concern of system interoperation. The lack of interoperability means that heterogeneous Knowledge Management Systems from different organizations are unable to communicate and integrate with one another, this results in limitation to reuse inter-organizational knowledge. Here, inter-organizational knowledge is defined as a set of explicit knowledge formalized and created by other organizations. In this research, a collaborative inter-organizational KM network is proposed to provide a platform for organizations to access and retrieve …

An Ontology-Based Simulation Model Exploring The Social Contexts Of Psychostimulant Use Among Young Australians, Pascal Perez, Anne Dray, Paul Dietze, David Moore, Rebecca Jenkinson, Christine Siokou, Rachael Green, Susan L. Hudson, Lisa Maher, Gabriele Bammer

SMART Infrastructure Facility - Papers

The principal anthropogenic factors driving reef degradation have been known for years, if not decades. Overfishing, sedimentation and nutrient loads are just some of the key impacts of human activities in and around reef communities. Therefore, the future of reefs does not rely on generating new knowledge, but rather on implementing and integrating the knowledge we already have. This will require creating effective links between researchers, managers and communities to promote mutual learning, negotiation and collaborative action for reef management. Combining agent-based models and role-play games, through a technique known as Companion Modelling (ComMod), creates a dynamic and interactive setting …

Ontology Mapping Between Hl7 Versions 2 And 3 And Openehr For Observations Messages, Amanda Ryan, Peter W. Eklund

Faculty of Commerce - Papers (Archive)

Interoperability between health informatics standards enables new best-ofbreed solutions to evolve from legacy health information systems, and enables a healthcare data model to evolve and be enriched. In this paper we show that a lightweight XSLT framework can be used to achieve interoperability between HL7 versions 2 and 3 and HL7 version 3 and OpenEHR. We present the necessary transformations between terminology and structure in these standards as an exercise in ontology mapping. We discuss our experience with respect to clinical observation messaging.

A Pragmatic Gis-Oriented Ontology For Location Based Services, Jun Shen, Aneesh Krishna, Shuai Yuan, Ke Cai, Yuemin Qin

Faculty of Informatics - Papers (Archive)

With advances in automatic position sensing and wireless connectivity, location-based services (LBS) are rapidly developing, particularly in fields of geographic, tourism and logistic information systems. Currently, Web service has been viewed as one of most significant innovations in business industry, and designed on demand to provide spatial related information for LBS consumption. However, the traditional Web Service Description Language (WSDL) cannot meet those requirements, as WSDL is not able to support semantic content and information. In recent years, Ontology came up with an effective approach to enhance service description, automated discovery, dynamic composition, enactment, and other tasks such as managing …

Ontology-Based Knowledge Representation For A P2p Multi-Agent Distributed Intrusion Detection System, Dayong Ye, Quan Bai, Minjie Zhang

Faculty of Informatics - Papers (Archive)

Many research efforts on application of ontology in network security have been done in the past decade. However, they mostly stop at initial proposal or focus on framework design without detailed representation of intrusion or attack and relevant detection knowledge with ontology. In this paper, the design and implementation of ontology-based knowledge representation for a peer-to-peer multi-agent distributed intrusion detection system (ontology-based MADIDS) are introduced. An example which demonstrates the representation of an attack with ontology and the relevant detection process is also presented. In ontology-Based MADIDS, ontology technique enables peers in the system and agents in one peer to …

A P2p Based Service Flow System With Advanced Ontology-Based Service Profiles, J. Shen, Y. Yang, Jun Yan

Faculty of Informatics - Papers (Archive)

A peer-to-peer (p2p) based service flow management system, SwinDeW-S, could support decentralised Web service composition, deployment and enactment. However, traditional workflow definition languages, such as extended XPDL and service-oriented BPEL4WS, have become insufficient to specify business process semantics, especially the descriptions of inputs, outputs, preconditions and effects. In this paper, we propose a novel solution based on OWL-S, a semantic Web ontology language that leverages service discovery, invocation and negotiation more effectively. The enhanced SwinDeW-S architecture is adapted with advanced ontology-based service profiles, and it takes advantage of a well-developed profile generation tool, which translates the BPEL4WS process models to …

An Ontology-Based Approach For Expert And Knowledge Mining In Complex Multi-Agent Systems, Minjie Zhang, Xijin Tang, Quan Bai, Jifa Gu

Faculty of Informatics - Papers (Archive)

Complex problems require diverse expertise and multiple techniques to solve. In order to solve such problems, complex multi-agent systems include numbers of heterogeneous agents, which may include both of human experts and autonomous agents, to work together toward some complex problems. Most complex multi-agent systems are working in open domains. Due to heterogeneities and dynamic working environments, expertise and capabilities of agents might not be well estimated and presented in the system. Therefore, how to discover useful knowledge from human and autonomous experts, make more accurate estimation for experts' capabilities and to find out suitable expert(s) to solve incoming problems …

A Framework Of Ontology Revision On The Semantic Web: A Belief Revision Approach, Seung Hwan Kang, Sim K. Lau

Faculty of Commerce - Papers (Archive)

The focus of the research in ontologies shifts from ontology representation to ontology evolution perspectives that become an important field of ontology research. Even though ontology refers to specification of conceptualisation that provides a useful way to represent the semantics of the Web resources, there is a still need for maintaining and handling ontologies. Because ontologies may change as a result of accepting new information, when this occurs, ontology needs to be revised. However the new information may contradict what was initially defined in the ontology when ontology revision is performed. To discuss this revision perspective, this research proposes an …
