2Overview
- 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
3Nanotech 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?
4Research 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?
5Hyperlink 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
6Identification 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)
7Data classification (174 sites)
- Basic generic and country TLD (automated)
- Organisational Type (manual)
- Producer
- Disseminator
- Commercialiser
- Dominant Orientation (manual)

- Technical
- OVERVIEW
8Nanotech 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

11Network measures by site type
12Top-10 sites (sorted on indegree, HITS hub
score)
13Analysis 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
14Multidimensional 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

18Conclusions 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.
19Conclusions 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?

24Organisational 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.
