Transcript

  • 1. The ‘Participatory Web’ and Data Visualisation Tools Stuart Macdonald EDINA National Data Centre & Edinburgh University Data Library
  • 2.
    • Context
    • DISC-UK DataShare
    • A JISC-funded collaborative project led by EDINA at the University of Edinburgh, with the University of Oxford, the London School of Economics (LSE) and the University of Southampton.
    • Explore new pathways to assist academics wishing to share their data over the Internet via Institutional Repositories (IRs)
    • Investigate alternative mechanisms for researchers to share data beyond the IR.
  • 3. Data Visualisation: The set of techniques used to turn a set of data into visual insight. It aims to give the data a meaningful representation by exploiting the powerful discerning capabilities of the human eye*. * Edinburgh Online Graphics Dictionary – http://homepages.inf.ed.ac.uk/rbf/GRDICT/grdict.htm
  • 4.
        • Programmableweb - http:// www.programmableweb.com /tag/mapping - map or spatial mash-up ‘resource discovery tool’
        • GeoCommons – http://geocommons.com/ - ‘brings intelligence to the GeoWeb, unleashing tools and data’ (downloadable as CSV, KML, Shape)
        • OpenStreetMap – http://www.openstreetmap.org/ free editable map of the whole world - see also Platial, Mapbuilder, Mapufacture

        • U.S. National Snow and Ice Data Center
        • USGS Earthquake Hazards Program
        • UNHCR layer in Google Earth – mash together news, images, video, statistical databases relating to refugees across the globe via the “Google Earth Outreach programme” - http://www.unhcr.org/events/47f48dc92.html
      • Spatial Data Visualisation
  • 5.
    • UCL Centre for Advanced Spatial Analysis -
    • develop computing technologies in several disciplines which deal with geography, space, location and the built environment - http://www.casa.ucl.ac.uk/
    • GeoVUE – one of the 7 nodes of the National Centre for e-Social Science set up to develop ‘new kinds of virtual urban environments’ (VUEs) through which users can participate in furthering their understanding of cities
      • London Profiler - link publicly available datasets such as Population Census to non-proprietary mapping e.g. visualising a neighbourhood's geodemographic profile using different area classifications through Google Maps - http://www.londonprofiler.org/
      • MapTube – a free resource for viewing, sharing, mixing and mashing maps online created by GMapCreator.
      • Engage in other forms of collaboration e.g. Virtual London (via Second Life)
  • 6.
    • … and there’s more
      • John Hopkins University’s Interactive Map Tool
        • Supports digital field assignments allowing users to create custom mashups using a variety of digital media, text and data – http:// www.cer.jhu/index.cfm?pageID =351
      • Minnesota Interactive Internet Mapping Project
        • A mapping application that provides maps and imagery similar to Google Maps – claims to be data rich, interactive, secure, easy to use, have analytical capabilities - http:// maps.umn.edu /
      • Research at Pompeu Fabra University, Barcelona
        • Researchers mining spatial-temporal data provided by geotagged Flickr photos of urban locations – http://www.giradin.org/fabien/tracing/
      • Thematicmapping.org
        • Thematic Mapping Engine (TME) enables you to visualise global statistics on Google Earth. The primary data source is UNData - http:// blog.thematicmapping.org /
  • 7.
    • Numeric Data Visualisation Tools:
    • ‘ Open’ ethos – anyone can upload/download or use data
    • Commercial Services embracing Web 2.0 business models
    • Collaborative and participatory – “harnessing collective intelligence”
    • The Death of Distance
    • Easy to use
  • 8.
    • But …
    • Ephemeral nature of web
    • Not trusted repositories / archives
    • If it’s computer generated and looks good it must be right!
  • 9. Numeric Data Visualisation Utilities http://graphwise.com/ http://numbrary.com/ http://www.swivel.com/ http://www.statcrunch.com/ http://www.data360.org/ http://manyeyes.alphaworks.ibm.com/ http://infochimps.org/ http://graphs.gapminder.org/world/ http://dabbledb.com/
  • 10.
    • Comparison of 8 Web 2.0 numeric data visualisation tools
    Upload data file
  • 11. Horizontal Bar Chart Pie Chart
  • 12.
    • Macro-data Visualisation

    • Wolfram|Alpha & Google Public Data Project
    • Wolfram|Alpha – ‘Computational Knowledge Engine’ (or giant semantic calculator)
      • Data maintained by Wolfram Research – collection of curated and standardised datasets include: astronomical, chemical; geopolitical; financial; biomedical; meteorological
      • Deploy formulas and algorithms to compute answers for searchers
      • Not editable nor interactive – output semantically poor (pixel images)
      • Share prices / weather data delivered in real-time
    • Google Public Data Project – ‘ a new search feature that makes it easy to find and
    • compare public data’
      • Data from US Bureau of Labour Statistics & US Census Bureau’s Population Division
      • Deploy Motion Chart * plus other visualisation tools from Gapminder Trendalyzer
      • Results to search query as interactive and customisable graphs
      • Data import facility
      • Soliciting more ‘free, authoritative, high quality’ data from governmental agencies,
      • research institutions
    * Public use component of Gapminder – part of the Google Visualisation API
  • 15. Google Squared – a Google Labs project – looks for facts from webpages, pulls them together, and organises them into a table with rows and columns e.g. search for Scottish Islands
  • 16. Other Semantic innovations Powerset - http://www.powerset.com/ (Microsoft) Hakia - http://www.hakia.com/ Calais - http://www.opencalais.com/ (Reuters) AdaptiveBlue - http://www.getglue.com/ Twine - http://www.twine.com/ Freebase - http://www.freebase.com/ (Metaweb)
  • 17.
    • Are such utilities a flash in the pan or here to stay?
    • Are they more appealing for researchers than IRs?
    • Is such functionality desirable in IRs?
    • Do they lack gravitas for academic purposes?
    • Can/should institutions support the use of these tools?
    • Do such ‘open data’ resources contribute to the ‘Global Database’?
    Food for thought ….
