Case for Support


"There is strong evidence that high levels of rural business aspiration are not being translated into
their full potential for growth, whilst high levels of entrepreneurship are not bringing with them
commensurate leve
ls of wealth creation”, that “[t]
here is also strong evidence that rural businesses
struggle to […] work effectively in partnership to address the obstacles they face” and that “[r]ural
areas need support to pioneer forms of brokerage and create virtual cl
usters or networks to access
such services and share good practice.”

(Burgess, 2008).

Social networks offer means for people to express their interests, views, etc. within a certain area,
link to and interact with others with similar interests, and, to som
e extent, discover others with
similar interests/views. These technol
ogies, through systems such as l
.com and r
are now becoming prevalent in the modern “wired” business world, with services intended, for
example, to help establish new busin
ess partnerships. These systems, effectively, provide a single
“shop front” for individual entrepreneurs or companies, presenting externally available information to
any other subscriber of the system. Potential partners are identified through keyword sear
ches or
browsing established business links. Such systems are restricted in the level of information available

typically high
level skills or service keywords

and hence offer only an initial point of contact that
may be followed up through traditional
means (face
face or virtual meetings, email, etc.). They
can, however, support the development of new business partnerships, but are most effective if the
number of subscribers is high.

At the same time, extensive research has been conducted in systems
for the (semi
gement of business processes (Jennings et al., 2000)
, the formation of coalitions to meet
identified market needs
(Norman et al., 2004;
De Roure
et al., 2005; Wang and Pan, 2007; Heath
and Motta, 2008)

and exploring important i
ssues such as security

and trust in such systems (Kagal
et al., 2004; Burnett et al., 2010)
. These systems rely upon the availability of detailed service
descriptions, often the existence of multiple, transferable, service providers, and (ideally) operate
trusted virtual marketplaces that treat all service providers equitably. Effort is required on the part of
service providers and consumers in ensuring that their offers and requirements, respectively, are
comprehensively and accurately described, and tr
ust must be placed in the system that privileged
service/costing information is kept secure. If these barriers to involvement can be overcome, these
systems offer significant benefits in opening new markets to businesses.

Many of the assumptions that under
pin the success of social networks and virtual marketplaces are
not necessarily valid in rural economies. In rural communities there is greater awareness of other
businesses in the area, but not necessarily the details of the range of services that may be
on offer.
Businesses tend to be smaller, but often more diverse in the range of services they offer. There are
fewer instances of the same service offering, and hence the benefits of open virtual marketplaces
are not so clear. In fact, the characteristics
of the business environment within rural communities are
such that interaction is more focused on collaboration than direct competition. The question here is:
how the benefits of social networking, semantic web and intelligent agent technologies be combine
to better support the formation of new and resilient business partnerships in rural communities?

Rural enterprise is not exclusively inward focussed, however. A critical issue in sustaining and
developing rural economies is for rurally located businesses

and entrepreneurs to compete in a
global marketplace. The use of social networking technologies can aid in reducing the impact of
barriers to collaboration due to location. The limitations of these technologies outlined above
remain, however: they provide

only simple (keyword search/browse) matchmaking services. The
question here is, therefore, how the benefits of social networking technologies be enhanced using
semantic web and agent technologies to better support and sustain rurally located business
ete in the wider marketplace?

Technological Focus

Social networks are designed to capture and support relationships between individuals, but
relationships are varied and have different social norms associated with them. The relationships
between individual
s may also vary over time and according to the context of the interaction between


them. Intelligent agents are highly suited to supporting interactions between individuals with such
complex interrelationships and dependencies. In this way, agents do not op
erate automatically
within, say, a marketplace, but work to support (teams of) human decision
makers; for example, in
supporting dialogue i
n a joint planning activity (Sycara et al., 2009)
. Such agent
based support has,
to date, been oriented to small grou
ps or pairs of individuals with shared goals, and so there is an
open research question concerning how these techniques can be scaled up to larger and looser
social networks, as well as how to perform dynamic semantic matchmaking based on real
data and knowledge from social network and business related data sources. There are,
however, technologies emerging that are oriented to such systems, including models developed by
the Semantically
Interlinked Online Communities (Breslin et al., 2007)

ect and the
Interchange Format (Rahwan et al., 2007)

The vision of this research project from the perspective of computing science is to explore how
agents can support individuals and groups in identifying business connections, provide accessibl
explanations of suggested partners given identified or specified needs, ensuring that individual
privacy policies are respected, and supporting dialogue within teams. This research vision is, we
believe, highly relevant for the development and support of

rural business networks and for the
support of rurally located businesses competing in a wider market.


illustrate some of the ideas presented above, consider the following scenario (suggested during
a meeting with partners in Cybermoor):


A small, rural
ly located design company receives a significant order for marketing materials
to be developed, printed and delivered. They have an existing contract with an ISP for
standard business applications such as email, website hosting, etc., and have worked with
reliable, high
quality printing firm in the past. The problem is that to deliver on this order they
need to identify a company that can provide reprographics services and need to transfer
large files with their partners that require greater bandwidth tha
n normally provided in their
contract with the ISP.


Through the
system, the
designer needs to identify potential reprographics
companies that can deliver a service within the timescale required. The system can support
this through matchmaking agains
t the service requirements specified by the designer.
Alternatively, the printing company may recommend an appropriate service provider that
they trust. Once identified the designer
contacts and engages in dialogue with
both the
printers and potential repr
ographics companies. Aided by an agent supporting the

goal of
a workflow for delivering on the order
the designer establishes an agreement
among them.


Individually or as a group they then approach the ISP (or ISPs) to put in place a short
higher bandwidth service the enable them to transfer files during the enactment of the


agreed workflow (or plan) is then managed in a decentralised manner by the agents
supporting each member of the team, and the order is delivered to spe

Each stage of this process

identifying potential business partners, establishing agreements
between them, adapting the team where necessary, and the construction of a joint plan of action
would, we envisage, be supported by intelligent agent
s that can identify options, present them in a
coherent way to decision
makers, support various types of dialogue between them (e.g. negotiation
and deliberation, or joint planning, dialogues), and keep track of decisions made and justifications
for those

Social Science


The current debates about social capital emphasise the role social networks in building community
cohesion. These social networks develop through and are enhanced by participation in associations
and civic life and a corolla
ry of this participation is the development of bonds of trust, which are a
prerequisite for collective social action
(Putnam, 2000, Halpern, 2005)
. Some studies have
emphasised the role of social

capital in improving business opportunities and here most stu
have focused upon business

links at a local level
(Uzzi, 1997)
. Regional policies have tried to build
on these findings through creating opportunities for interaction through business clusters and
business parks. However, rural busines
ses are usually small, frequently isolated by distance and


therefore less able to take advantage of this kind of business networking

(Rusten and Skerratt,
. Business associations such as the Chamber of Commerce try to bring together these
businesses to promote linking and to assist with representation of the business community more
generally. Other kinds of bus
iness clusters might emerge from other initiatives

the initiative “Plan
for Success” from Scottish Enterprise is one such example. Recent research suggests that it is
through sharing knowledge rather than acting in competitive isolation that
business ca
n be more

and indeed that information technology might be promoting this kind of sharing
communication culture
(Rifkin, 2009)

Research has suggested that infor
mation and communication technologies (ICT) can enable the
development of growth
oriented rural SMEs (Deakins et al. 2004). Technology, such a social
networking and workflow management systems, can help to reduce the impact of remoteness and
increase the g
lobal reach of businesses. However, as Smallbone and North (1999, cited in Huggins
and Izushi 2002) note, remote rural businesses are less likely than their urban counterparts to be
exposed to technology because they have fewer opportunities to interact wi
th other local
organizations that may be using such technologies, and also have a lower propensity to work with
larger organizations from which transfer of ICT understanding might take place and through which
ICT expertise may be developed. Where rural bus
inesses do trade beyond their local markets they
tend to be more sophisticated users of ICT (Grimes 2005). Furthermore, it is not clear whether I
has an enhancing or inhibiting role on the formation of social capital
(Huysman and Wulf, 2004)
The existence of strong social networks for example is a factor in the success of establishing
electronic networks
(Fukuyama, 1995)
. On the other hand, other evidence suggests that I
T can
help to create or enhance social capital
(Huysman and Wulf, 2004)
. The expandi
ng role of electronic
networking through media such as Linked
In, Facebook and other social networking sites would
suggest that electronic networking makes increasing use of “weak ties” to build communities of
interest or to find information (for example i
n searching for jobs)
(Granovetter, 1974)

and also by
helping businesses communicate with each other

even if they do share the same site
. This would sugge
st therefore that it can at least facilitate network ties and communication.
However, it seems clear that in rural areas, with dispersed populations and thin nets of enterprises,
electronic communications would lend themselves to better networking.

y rural small businesses tend to concentrate their efforts in supplying local markets rather than
reaching out into wider markets, though it has been noted that ICT can help to reduce the impact of
remoteness and increase the global reach of rural business
es (Deakins et al. 2004). Writers have
pointed to the need for areas that traditionally have low uptake of ICT to have appropriate methods
for stimulating the adoption of computer
based systems (Huggins and Izushu 2002). This suggests
that there is a perce
ived problem of incompatibility between solutions offered and the needs
perceived by rural enterprises. It is, therefore, important to understand the extent to which proposed
solutions meet the real needs of rural businesses. An desirable starting point in

developing tools for
use by rural enterprises is therefore to understand how, if at all, rural enterprises use ICT
networking to interact with other businesses or agencies serving rural communities, and how rural
enterprises envisage collaboration s
upport tools could aid them in growing and developing their

The research questions would focus upon: (i) identifying any (if they exist) ways in which rural
enterprises (or other enterprises) use networking sites and tools in developing busine
ss relations,
and to understand how such tools could be used; (ii) to what extent IT links can strengthen existing
social capital (frequency of communication, creating shared communities of interest, developing
trust etc.); (iii) to what extent this streng
thening of social capital might lead to enhanced business
opportunities/activities/growth/efficiency; (iv) what opportunities and barriers there are to inclusion in
IT networks of this kind; (v) establish what kind of networking tool works best for this gr
oup through
creation of the tool; (vi) the impact of the collaboration tool on relationships factors, such as trust
and ways of working, as the tool is deployed, and whether this may lead to suggestions of new
collaboration models.

Outline Project Plan

The aim of this project is t
o understand the impact of existing social networking technologies in
developing and sustaining rural enterprise, and to evaluate how Semantic Web and Agent
technologies can be exploited to enhance and add value to rural busines
s networks.



In meeting this aim, we will focus the research on the following work packages, work package 3
building upon work within 1 and 2, work package 4 building upon 3 each building upon each other:


Assess how existing social networking technologies a
re used by rural businesses both within
communities and to support wider collaboration. For what purpose are they used in what
business sectors, what are the perceived benefits and in what ways can these benefits be

In some user communities, no

such systems may be used at present, and during
this stage of the project we will work with user communities to provide off

networking systems (e.g. and investigate their use to provide a baseline for
future developments. [m

Explore, through mechanisms such as focus
groups, surveys and structured interviews (to
be decided), the possible ways in which semantic matchmaking and intelligent agent
technologies could enhance existing, and facilitate the formation of new business
collaborations. This exercise will be run joi

Deploy and evaluate a stable version of the ASSURE system with an existing rural business
community (identified in objective 1) with the aim of assessing the impact of next generation
social networking systems on rural enterprise.

A key component of this research agenda is to examine and assess the impact of the use of ICT to
support rural enterprise. This will involve a p
reliminary investigation with the group develo
through Scottish Enterprise’s
“Plan for Success”
. The network (consisting of about 20
30 businesses) is regionally based and has been reinforced by infrequent communication

face contact at
dinners, seminars

etc. The group are keen to expand their activities but have
variable knowl
edge of IT.

In order to measure impact it would be necessary to first gather “base line”
material and then to look at how interaction was transformed during the

course of the project
. This
would therefore proceed in a series of

stages as the project develo

Stage 1:

Attend a

meeting of the network and introduce the project. Elicit consent to


the project.

Stage 2:

Administering a questionnaire to all network participants to find out the extent of their
involvement in the network, how it hel
ped or hindered their business, to what extent they used IT
either personally or professionally.

Stage 3
: Introduce a fairly simple social networking technology geared towards business needs and
provide training to use it.

Evaluate how it has been used

rough in
depth interviews.

Stage 4
: Introduce more sophisticated applications having taken into account the needs of the
network and the evaluation at Stage

3. Co
production of materials.

Evaluate this stage through in
depth interviews

Stage 5:

re and f
inal evaluation.

Presentation of the findings at a meeting of the group.

Stage 6:
