    Participatory Web Participatory Web Presentation Transcript

    • The ‘Participatory Web’ and Data Visualisation Tools Stuart Macdonald EDINA National Data Centre & Edinburgh University Data Library
      • 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.
    • 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
          • 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

        • Spatial Data Visualisation
      • 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)
      • … 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 /
      • 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
      • But …
      • Ephemeral nature of web
      • Not trusted repositories / archives
      • If it’s computer generated and looks good it must be right!
    • 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/
      • Comparison of 8 Web 2.0 numeric data visualisation tools
      Upload data file
    • Horizontal Bar Chart Pie Chart
      • Macro-data Visualisation
          • OECD Country Statistical Profiles – OECD statistics in SDMX (Statistical Data Mark-up eXchange) - http://stats.oecd.org/nawwe/csp/default.html
          • IMF Data Mapper - http://www.imf.org/external/datamapper/index.php
          • Stat@tlas Europe - An online atlas of European statistical themes hosted by the Federal Statistical Office of Switzerland
          • Eurostat Tables Graphs Maps (TGM) - an interactive user interface to Eurostat data

      • Weaving History - http:// weavinghistory.org / - spatio-temporal visualisation of events
      • Open Economics - provides open content, data and code related to Economics - http://www.openeconomics.net/
      • Working groups: Open Environmental Data, Open Geodata
      • 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
    • 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
    • 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)
      • 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 ….
