Title: Mapping small things on the Web Assessing the online presence of the nanotechnology industry


1
Mapping small things on the WebAssessing the
online presence of the nanotechnology industry
  • Robert Ackland (Australian National
    University/OII)
  • Rachel K. Gibson (University of Leicester)
  • Wainer Lusoli (University of Chester)
  • Stephen Ward (Oxford Internet Institute)
  • voson.anu.edu.au

2
Overview
  • Aims
  • (1) Demonstrator project for new Web analysis
    software (developed by R. Ackland, ANU) that
    uses hyperlink data to map the structure and
    composition of online networks
  • (2) To investigate the extent to which the
    nanotechnology industry is engaging with the
    wider social/public debate
  • 2 Stage Process
  • Analysis of the web links (in/outbound) of the
    major nanotech companies
  • Analysis of social vs technical orientation of
    site content according to meta-keywords and home
    pages

3
Nanotech Networks Background
  • Growing concerns that nanotech might become the
    next GM
  • Move by government and academics to do things
    differently and engage with public concerns
  • Key question is whether the nanotech industry
    itself is part of this debate?
  • Match between rhetoric and reality?
  • Policy implications tighter regulatory
    regime?

4
Research Questions Hyperlinks and nano-networks
  • To what extent does the nanotech industry
    occupy/form an online network.
  • Who are the key players - industry/producers
    themselves or other groups?
  • What is the overall orientation
    social/technical?
  • What type of information is the nanotech industry
    providing to its audience?
  • Is it linking to the social debates?

5
Hyperlink Analysis
  • Why, oh why ?
  • General convergence/integration of the offline
    and online environments
  • Most measures of real world phenomena are
    proxies on what basis do we claim websites to be
    inauthentic representations of
    organisations/institutions?
  • Theoretical and empirical literature established
    the communicative function of hyperlinks
    (Ingwersen, 1998 Kleinberg, 1999 Davenport and
    Cronin, 2000 Rogers and Marre, 2000 Park et al
    2005)
  • Functions (or affordances) of hyperlinks
    (Ackland and Gibson, 2006)
  • Information provision
  • Network building
  • Identity building/branding
  • Audience sharing
  • Message amplification

6
Identification of the nano-sphere (if you excuse
the pun)
  • Step 1
  • VOSON crawls 25 seed sites (ML Nanotech index).
    Table 1
  • Google API used to identify sites linking to 25
    sites.
  • 1, 135 unique sites identified, 173 identified as
    important ( in outbound links to seeds lt 2)
  • Step 2
  • 22 of 173 important sites identified as having
    nano-related content.
  • 22 original 25 47 seed sites crawled
    outbound and inbound links
  • 4,456 new sites identified 798 important
    identified
  • 132 with nano in URL retained and added to
    original 47 179
  • Final dataset 174 nanotech sites (5 dropped)

7
Data classification (174 sites)
  • Basic generic and country TLD (automated)
  • Organisational Type (manual)
  • Producer
  • Disseminator
  • Commercialiser
  • Dominant Orientation (manual)
  • Social
  • Technical
  • OVERVIEW

8
Nanotech network structural properties
  • Indegree basic measure of visibility
  • Hyperlinked-Induced Topic Search (HITS) algorithm
    (Kleinberg, 1999)
  • Authority sites (highly referenced pointed to
    pages)
  • Hub sites (pages that point to lots of other
    pages)
  • Betweeness-centrality measure broker/bridging
    sites

Network measures by social/technical orientation

11
Network measures by site type
12
Top-10 sites (sorted on indegree, HITS hub
score)
13
Analysis of home pages content
  • A list of keywords was identified using meta-tags
  • Keywords were data-mined in the homepages of all
    website in the sample, using VOSON interface
  • Occurrence was coded dichotomous, content
    variables created
  • Results

14
Multidimensional scaling of content
  • Squared Euclidean distances were calculated
    between variables, pair-wise
  • Distance matrix was fed to Proxcals MDS to find
    common space coordinates of variables
  • Three dimension solution emerged

Conclusions research questions
  • Based on information provision, hyperlink and
    content analysis of homepages
  • producers of nanotech have very limited direct
    engagement in the social debate surrounding its
    use and development.
  • They are far more focused on the scientific and
    technical aspects.
  • Such producers are, however, linked into a wider
    network of knowledge disseminators and
    commercialisers that are engaging more directly
    in the social debate (particularly knowledge
    producer and blog sites).
  • Some of these sites enjoy a highly authoritative
    status in the network.

19
Conclusions where next ?
  • Overall, the research points to the need for
    further study
  • How will the network evolve over time. In
    particular, would a critical event stimulate
    the nanotech producers to engage more with social
    issues?
  • Have we identified a policy gap whereby the
    stated commitment to public dissemination and
    education is being ignored/neglected by the
    producers?

Organisational Types
  • Production - technology company
  • Sites of companies involved in activities
    pertaining to nanotechnology e.g. production of
    nanotechnology products, or equipment/services
    relating to nanotechnology.
  • Production knowledge
  • Sites of organizations producing research
    relating to nanotechnology e.g.
    government/academic research labs, think tanks.
  • Dissemination - academic
  • Academic sites disseminating information
    relating to nanotechnology.
  • Dissemination - basic/blog
  • Blogs and other small sites focused on
    nanotechnology.
  • Dissemination - industry
  • This category includes industry groups websites.
  • Commercial - consortia
  • Sites that involve partnerships between
    business, government and/or academia that are
    aimed at technology transfer.
  • Commercial - infosites
  • Sites that provide information on nanotechnology
    and are primarily focused on making profit e.g.
    by business services, consulting, job placements.
