Semantic annotation of digital music

AbstractIn recent times, digital music items on the internet have been evolving in a vast information space where consumers try to find/locate the piece of music of their choice by means of search engines. The current trend of searching for music by means of music consumersʼ keywords/tags is unable to provide satisfactory search results. It is argued that search and retrieval of music can be significantly improved provided end-usersʼ tags are associated with semantic information in terms of acoustic metadata – the latter being easy to extract automatically from digital music items. This paper presents a lightweight ontology that will enable music producers to annotate music against MPEG-7 description (with its acoustic metadata) and the generated annotation may in turn be used to deliver meaningful search results. Several potential multimedia ontologies have been explored and a music annotation ontology, named mpeg-7Music, has been designed so that it can be used as a backbone for annotating music items

A light-weight concept ontology for annotating digital music.

In the recent time, the digital music items on the internet have been evolving to an enormous information space where we try to find/locate the piece of information of our choice by means of search engine. The current trend of searching for music by means of music consumers' keywords/tags is unable to provide satisfactory search results; and search and retrieval of music may be potentially improved if music metadata is created from semantic information provided by association of end-users' tags with acoustic metadata which is easy to extract automatically from digital music items. Based on this observation, our research objective was to investigate how music producers may be able to annotate music against MPEG-7 description (with its acoustic metadata) to deliver meaningful search results. In addressing this question, we investigated the potential of multimedia ontologies to serve as backbone for annotating music items and prospective application scenarios of semantic technologies in the digital music industry. We achieved with our main contribution under this thesis is the first prototype of mpeg-7Music annotation ontology that establishes a mapping of end-users tags with MPEG-7 acoustic metadata as well as extends upper level multimedia ontologies with end-user tags. Additionally, we have developed a semi-automatic annotation tool to demonstrate the potential of the mpeg-7Music ontology to serve as light weight concept ontology for annotating digital music by music producers. The proposed ontology has been encoded in dominant semantic web ontology standard OWL1.0 and provides a standard interoperable representation of the generated semantic metadata. Our innovations in designing the semantic annotation tool were focussed on supporting the music annotation vocabulary (i.e. the mpeg-7Music) in an attempt to turn the music metadata information space to a knowledgebase

Pervasive healthcare in lived experience : thinking beyond the home : position paper for workshop on pervasive healthcare in the home.

The National Health Service (NHS) in the UK, like many other public heath services worldwide, is facing a number of key challenges. Among them are an ageing population and a rising incidence of chronic health conditions. This situation requires a radical re-examination of how people manage their health and their healthcare in ways that challenge the relationship between people and healthcare services. Combining this observation with the opportunities afforded by pervasive information and communication technologies, we argue that design research should reach beyond simply locating devices and services to offer healthcare ‘in the home’ and should examine this broader agenda. Rather than focussing design discourse on the specifics of one location, we should adopt a holistic view, beginning from people’s lived experience. In this position paper we describe the User-Centred Healthcare Design (UCHD) project, a 5-year collaboration between universities and NHS Trusts in South Yorkshire, UK. We suggest that new models of healthcare that re-define the institutional and social context of care are required if we are to meet the challenge of chronic illness. We describe our progress to date on the UCHD project, our commitment to placing patient experience at the centre of design, and our initial experiences of using an experience-based co-design method to improve outpatient services in a Sheffield hospital

Pervasive Healthcare in Lived Experience: Thinking beyond the home

Abstract The National Health Service (NHS) in the UK, like many other public heath services worldwide, is facing a number of key challenges. Among them are an ageing population and a rising incidence of chronic health conditions. This situation requires a radical re-examination of how people manage their health and their healthcare in ways that challenge the relationship between people and healthcare services. Combining this observation with the opportunities afforded by pervasive information and communication technologies, we argue that design research should reach beyond simply locating devices and services to offer healthcare 'in the home' and should examine this broader agenda. Rather than focussing design discourse on the specifics of one location, we should adopt a holistic view, beginning from people's lived experience. In this position paper we describe the User-Centred Healthcare Design (UCHD) project, a 5-year collaboration between universities and NHS Trusts in South Yorkshire, UK. We suggest that new models of healthcare that re-define the institutional and social context of care are required if we are to meet the challenge of chronic illness. We describe our progress to date on the UCHD project, our commitment to placing patient experience at the centre of design, and our initial experiences of using an experience-based co-design method to improve outpatient services in a Sheffield hospital. Keywords-component; User Centred Healthcare Design, NHS, SY-CLARHC,Pervasive Health, Experience The United Kingdom's (UK) National Health Service (NHS) was created as part of range of welfare services created in the UK at the end of the Second World War. At that time, the primary demand for healthcare services arose from acute diseases, and the NHS was structured in a way that treated people as compliant patients, whose role was to inform clinicians of their symptoms, and the NHS focused on diagnosing and treating patients' acute diseases. The delivery model was that services were provided through a series of discrete care episodes, involving the patient in movement between different clinicians and healthcare professionals and different departments over time. Now over sixty years old, these traditional deliverable structures and roles in the NHS are facing changed social and economic circumstances. Five specific changes can be identified: • An ageing population who often suffer from multiple health problems rather than single illnesses, who obtain care not only from multiple departments of the NHS but also from many different groups within and outside of the NHS (e.g. family, neighbours, social care agencies, third sector organisations). • A rising incidence of chronic health problems, with people being required to take more responsibility for their own care in between clinic visits; • The increasing availability of commercial products and services to assist in self-care; • Increased expectations from patients who are used to receiving co-ordinated, responsive and customercentred services from private sector corporations; • Increased desire on the part of some patients to be active, interested and informed participants in decisions about, and the delivery of, their healthcare. These socio-economic changes in the context of a public healthcare system geared to acute services means that patients often experience their healthcare as fragmented, episodic, opaque, and not matched to their expectations. In addition, the changing demographics and rise in chronic conditions challenge the long term financial sustainability of the NHS. Responding to the challenges requires fundamental rethinking about how the NHS is structured and the way services are designed and operated. User Centred Healthcare Design (UCHD) is a 5-year project within the "South Yorkshire Collaboration for Leadership in Applied Health Research and Care" (SY-CLAHRC), funded by the National Institute for Health Research. SY-CLAHRC is a large scale research collaboration focusing on the challenges of self-care in a range of long term conditions. UCHD brings together health researchers and managers based in the NHS with design and technology researchers at Sheffield Hallam University. Together, our aim is to develop, evaluate, and promote user-centred methods for designing usercentred healthcare services. In particular, to find ways of working within the public health system that will make possible the structural, behavioural and philosophical changes needed to meet these challenges. We work in collaboration with health researchers, healthcare providers, patients, carers and the public to investigate the impact of user-centred methods in healthcare designing, and the challenges faced in adopting such methods within established public healt

A Screening Assessment of the Impact of Sedimentological Heterogeneity on CO2 Migration and Stratigraphic-Baffling Potential: Sherwood and Bunter Sandstones, UK

We use a combination of experimental design, sketch-based reservoir modelling, and flow diagnostics to rapidly screen the impact of sedimentological heterogeneities that constitute baffles and barriers on CO2 migration in depleted hydrocarbon reservoirs and saline aquifers of the Sherwood Sandstone Group and Bunter Sandstone Formation, UK. These storage units consist of fluvial sandstones with subordinate aeolian sandstones, floodplain and sabkha heteroliths, and lacustrine mudstones. The predominant control on effective horizontal permeability is the lateral continuity of aeolian-sandstone intervals. Effective vertical permeability is controlled by the lateral extent, thickness and abundance of lacustrine-mudstone layers and aeolian-sandstone layers, and the mean lateral extent and mean vertical spacing of carbonate-cemented basal channel lags in fluvial facies-association layers. The baffling effect on CO2 migration and retention is approximated by the pore volume injected at breakthrough time, which is controlled largely by three heterogeneities, in order of decreasing impact: (1) the lateral continuity of aeolian-sandstone intervals; (2) the lateral extent of lacustrine-mudstone layers, and (3) the thickness and abundance of fluvial-sandstone, aeolian-sandstone, floodplain-and-sabkha-heterolith and lacustrine-mudstone layers. Future effort should be focussed on characterising these three heterogeneities as a precursor for later capillary, dissolution and mineral trapping
