Continuous metadata flows for distributed multimedia
No full textThe practical use of temporal multimedia has increased markedly in recent years as enabling technologies for the distribution and streaming of media have become available. As a part of this trend, hypermedia systems and models have adapted accordingly to incorporate such distributed multimedia for presentation. Structured interpretation of information has long been a fundamental feature of both open hypermedia systems and knowledge systems. Metadata, in its many forms, has become the cornerstone for providing this structured knowledge above and beyond basic data and information. This thesis presents the rationale and requirements for continuous metadata, which supports the metadata accompanying distributed multimedia throughout the lifecycle of streamed media, from generation, through distribution, to presentation. Throughout this process it is the temporal and continuous nature of the metadata which is paramount. A conceptual framework for continuous metadata is proposed to encapsulate these principles and ideas. Continuous metadata and the associated framework enable the development, in particular, of real-time, collaborative, semantically enriched distributed multimedia applications. Experience building one such system using continuous metadata is evaluated within the framework. An ontology is developed for the system to enable the collation, distribution, and presentation of structure aiding navigation of multimedia, and it is shown how continuous metadata utilising the ontology can be distributed using multicas
The Semantic Web and Why You Should Care
No full textThe Semantic Web is much discussed as a possible panacea for data distribution/discovery/exploration/leverage/storage etc. But what is it? What is all the fuss about? Where does this 'Linked Data' fit in? Will it all work? We attempt answer these questions, favouring scope and context over formality
Mapping Manuscript Migrations Knowledge Graph
No full textThe Mapping Manuscript Migrations (MMM) project transformed three separate datasets into a unified knowledge graph. The source databases include:
* Schoenberg Database of Manuscripts from the Schoenberg Institute for Manuscript Studies;
* Bibale database from the Institute for Research and History of Texts,;and,
* Medieval Manuscripts Catalogue from the Bodleian Libraries.
To test and demonstrate its usefulness, the MMM Knowledge Graph is in use in the MMM Semantic Portal, where it is explained in more detail:
https://mappingmanuscriptmigrations.org/about The Mapping Manuscript Migrations portal links disparate datasets from Europe and North America to provide an international view of the history and provenance of medieval and Renaissance manuscripts. Researchers are able to analyse and visualize the aggregated data at scales ranging from individual manuscripts to thousands of manuscripts. Our research addresses the origins and movements of these manuscripts, and the collectors and owners involved in their history. We show how these manuscripts have traveled across time and space to their current locations, where they continue to find new audiences

REST and Linked Data: a match made for domain driven development?
No full textAt a first glance there might appear to be an obvious alignment and overlap between the approaches prescribed by REST and Linked Data. On more detailed inspection divergences in scope and applicability present themselves, and for some aspects, incompatibility. In this paper we investigate these similarities and differences and suggest the coupling is worthy of a third look: in combination as a flexible environment in which the developer can focus on domain driven applications
WhatILike - Position Paper
No full textFoaF has been a phenomenally successful activity. Individuals around the world have generated more ontologically-powered metadata, possibly by several orders of magnitude, than any other activity or tool. FoaF is primarily fuelled by the excitement of people who are pleased to publish facts about themselves in a form that allows other people and tools to process them. FoaF publishes against a fixed ontology, to which many extensions exist that allow virtually any information about oneself to be coded. FoaF primarily enfranchises people who understand what is happening; this is because the tools to build FoaF descriptions are generally rather limited. The utilities that use the FoaF descriptions are restricted because they can only use FoaF data. It is interesting to explore what might be considered a next step. How might we allow a more fluid ontological framework? How would we enfranchise people who understand less about what is happening, against a more fluid ontological framework? How do we simply encourage people to produce even more metadata
It's About Time: Link Streams as Continuous Metadata
No full textAs enabling technologies become available there is an increasing use of temporal media streams, such as audio and video, within a hypertext context. In this paper we present the rationale and requirements for delivering continuous metadata alongside the media stream, and focus on linking as our case study. We consider the mechanism for delivery of the metadata across a distributed system, the format and content of the metadata flow itself, and the presentation of the media and augmenting metadata to the user. Two initial proof of concept applications have been developed to demonstrate these concepts, which we describe. Finally we propose a framework for highly distributed delivery and processing of multicast continuous metadata, as a part of the infrastructure necessary to provide a more complete multimedia environment for hypermedia systems
Continuous Metadata
No full textMetadata for multimedia content can describe the detail of content in order to facilitate processing, for example identifying events along the time axis in temporal media, as well as carrying descriptive information for the overall resource. In both cases the metadata is essentially static and may be associated with, or embedded in, the multimedia content; it may also convey low level signalling data or higher level knowledge such as annotation by users. This paper discusses the case for working with semantically rich metadata as one or more distinct and continuous live flows, managed, delivered and processed separately from the content. It discusses a prototype system designed to explore the use of continuous metadata in videoconferencing and its extension to smart meeting spaces
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
