Memetic: from meeting memory to virtual ethnography & distributed video analysis

The JISC-funded Memetic2 project was designed as knowledge management and project memory support for teams meeting via the Access Grid environment (Buckingham Shum et al, 2006). This paper describes how these capabilities also enable it to serve as a novel distributed video analysis tool to support interaction analysis. Memetic technologies can be used to record, annotate and discuss sessions recorded within a flexible, visual hypermedia environment called Compendium. We propose that beyond the use originally conceived, the Memetic toolset could find wide ranging applications within social science for virtual ethnography and data analysis

The Pipeline of Enrichment: Supporting Link Creation for Continuous Media

The application of open hypermedia to temporal media has previously been explored with respect to the link service, in particular link delivery and generic linking. This paper is based on the notion of continuous metadata, in which we use metadata in a temporally significant manner to capture and convey the information required to support linking. With a focus on link creation and live processing, our approach enriches hypermedia content with additional metadata at a number of points between capture and delivery. We illustrate this approach with a tool which assists metadata capture by annotation of continuous media according to a simple ontology

Continuous Metadata

Metadata 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

Korean experience with the OSTA risk index for osteoporosis: a validation study.

The Osteoporosis Self-assessment Tool for Asians (OSTA) was developed to help physicians focus their efforts on patients at increased risk, and encourage appropriate use of bone mineral density (BMD) measurements. Previously, OSTA performed well in a sample of women from eight countries in Asia, and in a validation group of Japanese women. In this study, we evaluate the performance of OSTA using a sample of 1101 postmenopausal women from a clinic in Korea who had femoral neck BMD measurements by dual-energy X-ray absorptiometry (DXA). The OSTA had a high sensitivity (87%), and good specificity (67%) for identifying osteoporosis (BMD T-scores -1) to 64% among those classified as high risk (OSTA < -4); these results were almost identical to those reported earlier for a sample of women from eight Asian countries. We conclude that the OSTA risk tool performed well in this sample of postmenopausal Korean women, similar to previous results in other Asian women. The OSTA tool is free and very easy to use; risk can be tabulated by age and weight, so that calculations are not necessary. Using OSTA could encourage patients and clinicians to actively assess osteoporosis, and measure BMD when appropriate, before fractures occur

Memetic : semantic meeting memory

This paper introduces the Memetic toolkit for recording meetings held over Internet-based video conferencing technologies, and making these navigable in linear and nonlinear ways. We introduce the tools and technologies that form the toolkit and discuss the semantics of the information they capture

MEMETIC : an infrastructure for meeting memory

This paper introduces the Memetic toolkit for recording the normally ephemeral interactions conducted via internet video conferencing, and making these navigable and manipulable in linear and non-linear ways. We introduce two complementary interaction visualizations: argumentation-based concept maps to elucidate the conceptual structure of the discourse using a visual language, and interactive event timelines generated from the meeting metadata. We discuss in detail the affordances of Memetic's tools, in particular the Compendium hypermedia mapping tool, and the Meeting Replay tool that renders the semantic navigation indices into the videoconference replays. Additionally, with respect to methodology and evaluation, we describe how we are engaging diverse end-user communities in the process of designing and deploying these tools
