ABSTRACT
The world is experiencing an era which is termed as “knowledge age”. In this new context,
knowledge is the primary commodity and management of knowledge becomes more and more
crucial. Knowledge network is an effective method for knowledge management. KN is a method
used for combining individual’s knowledge and skills in pursuit of personal and organizational
objectives. Knowledge network is grounded not just the application of existing explicit
knowledge, but the sharing of tacit and implicit knowledge.

1. Introduction
Over the last three decades the use of computers has steadily changed along the
spectrum from aiding computation (data processing) to communications (email etc.). It is now
entering a new era of helping cognition - human thinking and knowledge processes. However
much information organizations store in computer only a small fraction of the knowledge needed
to run an enterprise is encapsulated in this form or in manual procedures - 10%-30% is the figure
given by most groups asked to estimate this percentage. The rest is the tacit knowledge and
wisdom in people's heads.
Tacit knowledge becomes even more important in a dynamic business environment and
is the key to an organization’s ability to respond in a flexible and timely manner. This is a role that
knowledge networking can help fill.

2. Information hierarchy
The content of the human mind can be classified into five categories:
1. Data: Data is raw. It simply exists and has no significance beyond its existence (in and of
itself). It can exist in any form, usable or not. It does not have meaning of itself. In computer
parlance, a spreadsheet generally starts out by holding data.
2. Information: Data that are processed to be useful; provides answers to "who", "what",
"where", and "when" questions information is data that has been given meaning by way of
relational connection.
3. Knowledge: Application of data and information; answers "how" questions. Knowledge is
the appropriate collection of information, such that it's intent is to be useful. Knowledge is a
deterministic process.
4. Understanding: Appreciation of "why”. Understanding is an interpolative and probabilistic
process. It is cognitive and analytical. It is the process by which I can take knowledge and
synthesize new knowledge from the previously held knowledge. The difference between
understanding and knowledge is the difference between "learning" and "memorizing".
Knowledge Networks
8 Department Of Computer Science
5. Wisdom: evaluated understanding. Wisdom is an extrapolative and non-deterministic, non-
probabilistic process. It calls upon all the previous levels of consciousness, and specifically
upon special types of human programming (moral, ethical codes, etc.).
3. Knowledge
Knowledge is the knowing familiarity gained by experience; person’s range of
information; a theoretical or practical understanding of; the sum of what is known.
There are three types of knowledge:
i) Explicit knowledge
ii) Tacit knowledge
iii) Implicit knowledge
Explicit knowledge is that which is written down, recorded or codified in some manner
is often used almost interchangeably with information in the knowledge management /knowledge
network context. The mapping and sharing of knowledge focuses primarily on individual explicit
knowledge and its relation to organizational explicit knowledge.
Tacit knowledge is the understanding of how to do things. It is created by doing, by
personal trial, error, reflection and revision ie. Understanding how to research and develop new
policy recommendations, learning how to run a community consultation or how to negotiate a
policy change with a decision-maker. But it is difficult to articulate what that
“how to” actually is. The transfer of tacit knowledge is, therefore, through shared processes
ie.working together, mentoring, and so forth in addition to the physical transmission of written or
recorded content.
Finally, implicit knowledge refers to an individual’s “contextual surroundings … that
are imbued with and shape his collective values, normative behavior, roles, customs, and
expectations of events” in short, an individual's culture and values.

4. Knowledge management
In an economy where the only certainty is uncertainty, the one sure source of
lasting competitive advantage is knowledge.” This change of focus forces organizations to re-think
the way they manage their business since the focus is no longer on tangible assets but on people’s
abilities and experience. In the industrial economy if people thought about knowledge at all they
operated from the old equation: knowledge is power, so hoard it. Today companies are embracing a
new equation for success: knowledge is power, so share and it multiplies. This new logic represents
a radical rethinking of basic business and economic models.
Knowledge-focused strategic domains:
• Sharing knowledge and best practices
• Instilling responsibility for sharing knowledge
• Capturing and reusing past experiences
• Embedding knowledge in product, services and processes
• Producing knowledge as a product
• Driving knowledge generation for innovation
• Mapping networks of experts
• Building and mining customer knowledge bases
• Understanding and measuring the value of knowledge
• Leveraging intellectual assets
Such focus areas are typical of companies that embrace the sharing of
knowledge across organizational boundaries. Corporate know-how is important at strategic levels
to sense the environment and challenge management assumptions. At the tactical level, day-to-day
decision making requires that people talk candidly, share their experience and insights, and find
meaning together. At the operational level, replicating best practices throughout the company

quickly and effectively can lead to greater efficiencies, lower costs and higher quality of goods and
services.
Two main streamlines of knowledge management focus on different approaches:
Information Management Personnel Management
Knowledge network is an effective method for knowledge management which
integrate these two approaches
Knowledge as network IT network Use and reuse of
knowledge
Knowledge as process Social network Creation of knowledge

5. KNOWLEDGE NETWORK
Knowledge network is described by Newman. KN mainly for interactive knowledge
creation and use. Interdisciplinary communities can share knowledge and build knowledge for
complex problems .It uncovering expertise within the organization and connections to/with
external contacts. Basically it is a set of relationships. It is more focused and narrowly based than
informal network. It is an effective way of combining individuals’ knowledge and skills in pursuit of
personal and organizational objectives.
5.1 Need The Web has become an indispensable tool of modern culture. To a degree, its
initial promise of creating a global network that offers access to the knowledge of the world has
been realized. It supports advanced technological research in the sciences, arts, and humanities, but
it also has popular appeal (online news, media, telecommunications) and has drawn wide public
engagement (Flickr, Wikipedia). Powerful, but relatively crude, search engines organize the
enormous amount of information on the Internet into simple answers to clear cut, search term-based
questions. What is deceptive about this everyday process is that it flattens rather than deepens and
improves knowledge since popular search engines enforce a historical perspective; the Web does not
support the long-tail effect.
5.2 Operating principles Knowledge networks consist of groups of expert institutions working together on a
common concern, strengthening each other's research and communications capacity, sharing
knowledge bases and developing solutions that meet the needs of target decision
Based on this definition, there are several operating principles for formal networks:
1. Knowledge networks are purpose driven.
We have observed that the narrower the focus, the more influential a network
becomes. The institutional collaboration takes place around a single issue or problem rather than a
broad spectrum of interests. Focus is essential. The network's research on the issue should be
Knowledge Networks
12 Department Of Computer Science
transdisciplinary. The purpose of the network could be thematically based (ex. trade,
dams, ozone depletion) or regionally focused (ex. environmental policy options in Central America).
2. Knowledge networks are working networks.
One of the greatest challenges in setting up and running a network is moving the
participants beyond basic information exchange to actually working together on solutions. In our
view, knowledge networks are far more "work" than "net.”? A working network is driven not just
by research but by implementation. As part of creating work plans for the network, the members
should focus on how the results of the network's research will be used. The work plans should
include strategies for the application of the research: How will the research be linked to the public
policy process? How will the process or technology developed by the network be commercialized
or put into practice by those outside the network?
3. Knowledge networks require institutional commitment beyond the participation of
individuals and experts.
While expert networks and consultative groups have their place, we have learned
that a knowledge network requires the commitment of an institution for several reasons.
Accountability: The participants in the network represent institutional
mandates rather than personal research interests. The agenda is, therefore, more
likely to be focused on implementation. Participants are also held accountable for
their work not only by their colleagues in the network, but by the institutions they
represent.
Continuity: Networks can take up to a decade to thrive and have real impact. With
institutional commitment, it is more likely that work will continue even if individual
staff changes.
Commitment of resources: The network activities will be endorsed as part of each
institution's mandate, making easier the justification of both financial and in-kind
support from participating institutions and ensuring their involvement in promoting
the results of the network's research. 4. Knowledge networks are built on expertise, not just interest alone.
Knowledge Networks
13 Department Of Computer Science
The identification and selection of members is one of the most important tasks of the
network. The reputation of the network, and the level of influence it will have, will be based on the
expertise and credibility of the members. We also suggest, as guiding principle, that institutional
membership be based on expertise and the capacity to undertake the research and implement work
plans. Interest in an issue is not, in itself, reason enough to include an organization in a knowledge
network.
Membership in a formal network should be based on merit. In order for a knowledge
network to create new knowledge and to have real influence, that knowledge and influence must be
grounded in expertise and reputation. If exclusivity is a concern of the network, then
communications mechanisms can be employed to bring points of view from outside of the
immediate network membership. These include workshops, electronic conferences, the nomination
of associate members for specific activities and the formation of more open, dynamic "working
groups" within the formal network.
5. Knowledge networks are cross-sectoral and cross-regional.
Knowledge networks should result in a reduction of boundaries between sectors such
as universities and industry, or governments and civil society.
6. Knowledge networks must develop and strengthen capacity in all members.
Strengthening capacity is critical to the formal knowledge network model: we create
knowledge networks in order to learn from each other and build on each other’s strengths. Capacity
development occurs at all points in the work plan: in research management; in the substantive
issues; in virtual teamwork; in communicating findings more broadly; and in influencing decision-
making. An underlying premise of a knowledge network is that the whole is greater than the sum of
the parts. However, a significant benefit of participating in a knowledge network is that each of the
parts becomes stronger.
7. Knowledge networks are communications networks.
This final principle underpins all the others. The knowledge created and
aggregated by the network must be shared beyond the network members. This operating principle is
part and parcel of a network being a purpose-driven, working network. Mechanisms must be put in
place from the beginning to reach targeted decision-makers who will be the ones to put the research
of the network into action.
Knowledge Networks
14 Department Of Computer Science
5.3 Structure of Knowledge network When people think about some things or events, all the concepts (nodes) are
connected by some relations or Laws (links) to formulate a network. The network can be used as a
thinking and knowledge presentation tool .For a working group, the concepts of all members with
different expertise will be integrated as a large network
There are three kinds of linking in the knowledge network system:
1. Linking knowledge to knowledge: The different units of knowledge can be linked. It is
the necessary condition for the knowledge integration.
2. Linking people to knowledge: This is the important way for people to get the knowledge.
and In reverse direction users can find the related people from the knowledge.
3. Linking people to people. This forms a social network.
5.4 Components of Knowledge Network Knowledge architecture can be regarded as a prerequisite to knowledge sharing.
The infrastructure can be viewed as a combination of people, content, and technology.
The People Core
By people, here we mean knowledge workers, managers, customers, and suppliers. As
the first step in knowledge architecture, our goal is to evaluate the existing information/ documents
which are used by people, the applications needed by them, the people they usually contact for
solutions, the associates they collaborate with, the official emails they send/receive, and the
database(s) they usually access. All the above stated resources help to create an employee profile,
which can later be used as the basis for designing a knowledge management system. The idea behind
assessing the people core is to do a proper job in case of assigning job content to the right person
and to make sure that the flow of information that once was obstructed by departments now flows
to right people at right time.
Knowledge Networks
15 Department Of Computer Science
The Technical Core
The objective of the technical core is to enhance communication as well as ensure
effective knowledge sharing. Technology provides a lot of opportunities for managing tacit
knowledge in the area of communication. Communication networks create links between necessary
databases. Here the term technical core is meant to refer to the totality of the required hardware,
software, and the specialized human resources. Expected attributes of technology under the
technical core: Accuracy, speed, reliability, security, and integrity. Since an organization can be
thought of as a knowledge network, the goal of knowledge economy is to push employees towards
greater efficiency/ productivity by making best possible use of the knowledge they posses.
Content core Knowledge stored in the database Procedures Access, Navigation, Observation, Analysis, Collaboration, Learning
5.5 Process in KNS
The knowledge network system aims at the integration all the knowledge resources at
all the levels (as well as the whole Internet) and provides easy and flexible means for the knowledge
capturing, processing, and creation. In the daily work, people get their knowledge through the
following ways: Searching and finding knowledge on paper (explicit knowledge). Meeting persons
in real life to get explicit and tacit knowledge. Using multimedia communication tool like telephone,
TV to get some knowledge. From personal computer, in which there exist some knowledge
captured and stored .From the distributed knowledge network (DKN) at different level. Creating
new knowledge after capturing, integrating existing knowledge and creative mental process .For the
effective processing the knowledge, the concept of knowledge node is introduced. A knowledge
node is a kind of high level processing unit. It has three main functions:
1. Dissemination of information on request or automatically channelled.
2. Two way communication and feedback capacities through multimedia interfaces.
3. Access to a local knowledge bank and possibly meta knowledge about other knowledge
nodes.
Knowledge Networks
16 Department Of Computer Science
At the lowest level, a technological innovation is preceded by a number of
interconnected scientific and technological facts (concepts). In the basic research work, those
facts may present new scientific ideas, theories, empirical achievements, discoveries, etc in
different scientific disciplines. In applied research work, they are advances in different
technologies, e.g. new technical solutions, inventions, new principles and methods of design and
manufacturing, etc. A network can be constructed by connections between these facts or concepts.
Each node can be interlinked to another node at different levels
The more important point is each new concept may play a catalytic role in triggering
out new ideas and their applications to extending knowledge. If we can mine the existing
networks and explore some pieces of network and integrate them, some prototypes of knowledge
generating network may be expected, though it can not guarantee to perfect success. The most
crucial task for the knowledge management is knowledge conversion and creation. A typical
approach is put forward by Nonaka and Takeuchi. They assumes that knowledge is created
through the interaction between tacit and explicit, individual and organizational knowledge, and
proposes four modes of knowledge conversion.
5.6 Nonaka's Model of Knowledge Creation & Transformation
In 1995, Nonaka coined the terms tacit knowledge and explicit knowledge as the
two main types of human knowledge. The key to knowledge creation lies in the way it is mobilized
and converted through technology.
Tacit to tacit communication (Socialization): Takes place between people in meetings or in
team discussions.
Tacit to explicit communication (Externalization): Articulation among people trough
dialog (e.g., brainstorming).
Explicit to explicit communication (Communication): This transformation phase can be
best supported by technology. Explicit knowledge can be easily captured and then
distributed/transmitted to worldwide audience.
Knowledge Networks
17 Department Of Computer Science
Explicit to tacit communication (Internalization): This implies taking explicit knowledge
(e.g., a report) and deducing new ideas or taking constructive action. One significant goal of
knowledge management is to create technology to help the users to derive tacit knowledge
from explicit knowledge.
5.7Layers of KNS The knowledge network system composed of 5 layers
1. User interface layer
2. Authorized Access Layer
3. Collaborative Intelligence and Filtering Layer
4. Knowledge-Enabling Application Layer (Value-Added Layer)
5. Transport Layer
6. Middleware Layer
7. Repositories Layer
User Interface layer
It is the top layer in the KM system architecture. A web browser represents the
interface between the user and the KM system.It provide a way for the proper flow of tacit and
explicit knowledge ie, Capturing tacit knowledge from experts and making it available to people
User interface layer should have following features:consistency, relevancy ,visual clarity ,usability
,ease of navigation
Authorized Access Layer
This layer maintains security as well as ensures authorized access to the knowledge
captured and stored in the organization's repositories. The knowledge is usually captured by using
internet, intranet of extranet. An organization's intranet represents the internal network of
communication systems. Extranet is a type of intranet with extensions allowing specified people
(customers, suppliers, etc.) to access some organizational information. Issues related to the access
layer: access privileges, backups. The access layer is mostly focused on security, use of protocols
(like passwords), and software tools like firewalls.
Knowledge Networks
18 Department Of Computer Science
Firewalls can protect against:
E-mails that can cause problems.
Unauthorized access from the outside world.
Undesirable material (movies, images, music etc).
Unauthorized sensitive information leaving the organization.
Firewalls can not protect against:
Attacks not going through the firewall.
Viruses on floppy disks.
Weak security policies.
Collaborative Intelligence and Filtering Layer
This layer provides customized views based on stored knowledge. Authorized users
can find information (through a search mechanism) tailored to their needs. Intelligent agents (active
objects which can perceive, reason, and act in a situation to help problem solving) are found to be
extremely useful in some situations. In case of client/server computing, there happens to be frequent
and direct interaction between the client and the server. In case of mobile agent computing, the
interaction happens between the agent and the server. A mobile agent roams around the internet
across multiple servers looking for the correct information.
Some benefits can be found in the areas of:
Fault tolerance.
Reduced overall network load.
Heterogeneous operation.
Key components of this layer: The registration directory that develops tailored
information based on user profile. Membership in specific services, such as sales promotion, news
service etc. The search facility such as a search engine. In terms of the prerequisites for this layer,
the following criteria can be considered: Security, Portability, Flexibility, Scalability, Ease of useand
Integration.
Knowledge Networks
19 Department Of Computer Science
Knowledge-Enabling Application Layer (Value-Added Layer)
This creates a competitive edge. Most of the applications help users to do their jobs
in better ways. They include knowledge bases, discussion databases, decision support etc.
Transport Layer
This is the most technical layer. It ensures to make the organization a network of
relationships where electronic transfer of knowledge can be considered as routine. This layer
associates with LAN (Local Area Network), WAN (Wide Area Network), intranets, extranets, and
internet. In this layer we consider multimedia, URL's, connectivity speeds/bandwidths, search tools,
and consider managing of network traffic.
Middleware Layer
This layer makes it possible to connect between old and new data formats. It
contains a range of programs to do this job.
Repositories Layer
It is the bottom layer of the KM architecture which represents the physical layer in
which repositories are installed. These may include, legacy applications, intelligent data
warehouses, operational databases etc. After establishing the repositories, they are linked to form
an integrated repository.
5.8Components for success We have found that effective formal knowledge networks usually have certain
components, some of which are well-understood and have been extensively documented and others
which are less well-understood or previously uninvestigated
1. External communications and engagement strategies for network audiences
According to our principles, knowledge networks need to be purpose driven,
workingnetworks, and they must be communications networks. This means that the knowledge
created by the network must be for broader application outside of the network. There are two levels
of audience for networks: the target audience - those whom the network most wants to influence
with the outputs of its work broader audiences - those individuals and organizations interested in
Knowledge Networks
20 Department Of Computer Science
or working on the same issues as the network. Each network should continually ask what impact it
hopes to have and on whom. The participants should determine their target audience with as much
specificity as possible. The network should consider how it will move its advice and solutions into
practice.
2. Relationship building, management and governance
It explores the need for setting network goals and objectives (the"purpose" or
focus of the network), network membership issues, governance and decision-making mechanisms,
day-to-day management through a secretariat or coordinating unit, funding and resource sharing
issue. The network falls into disuse without institutional commitment and staffing to continually
push all of the participants. The opportunity to develop new policy recommendations and new
development practices would be lost without this level of attention
3. Internal communications infrastructure and virtual teamwork protocols
For members to learn from each other and build on each other’s strengths,
knowledge networks require a communications infrastructure and protocols to support the joint
work of network members. An important step in managing a knowledge network is the creation of a
private, closed “extranet” to link the network members.
4. Evaluation mechanisms
It is a common observation that what you can't measure, you can't manage. More
research on measuring the overall performance of knowledge networks is required in order to
manage them more effectively. We think that pooling our knowledge and staff resources in a
knowledge network may result in more cost-effective research, particularly when adequately
supported by information and communications technologies.
Knowledge Networks

5.9 Case study
1. Halliburton energy services, Texas started a number of knowledge networks as part of
knowledge management implementation
Let us assume that a user has a question. The user performs a self-search and
looks in the Knowledge Repository for relevant information. If the user cannot find what she/he
needs in the repository, then she/he posts the issue on the collaboration tool in the community
portal. The community members can contribute suggestions, share experiences, and help clarify the
scope of the problem until a solution is found. The community of practice has a full-time
“Knowledge Broker” (KB) who connects those who know with those who need to know. An
important part of developing the community is identifying individuals around the globe who have
specific expertise. The Knowledge Broker then connects those individuals with expertise to those
within the community who need it. Once solutions are validated by a subject matter expert (SME)
and acknowledged as a viable solution by the user, the KB tags the solution with taxonomy
attributes and metadata and places it in the knowledge repository for further use.
Knowledge Networks
22 Department Of Computer Science
Another component of the community learning system not apparent in the
processes described above is ‘learning on demand’. As users access the community portal, there are
new issues and questions posted to the collaboration tool daily. Users learn by reading the postings,
comments and solutions of others, as well as their own. The collaboration postings and threaded
discussions are a rich source of knowledge and information, and can be searched using the portal
search tool. Users do not have to wait until this posting is placed in the knowledge repository to
have access to it.
2. Knowledge network of Infosys solutions
Main co mponents of the system are:
KM portal: a central repository for contents
People knowledge map: a directory service for locating experts
Knowledge exchange: a set of online discussion forums
K-mail: an auto response generator and work flow engine for answering questions
Knowledge Networks

6. Conclusion
www flattens rather than deepens and improve the knowledge,butKnowledge
network concentrate on knowledge than raw information. The Cabinet Committee on Infrastructure
has accorded in principle approval for the establishment National Knowledge Network (NKN).The
knowledge network is planned to be implemented by the NIC and will inter-connect all knowledge
institutions trough high speed data communication network.NKN would encourage sharing of
knowledge, specialized resources and collaborative research among scientists, researchers and
students from diverse spheres across the country to work together for advancing human
development in critical and emerging areas.NKN will catalyze knowledge sharing and knowledge
transfer between stakeholders seamlessly– that too across the nation and globally for creating
intellectual property.NKN would enable use of specialized applications and allow sharing of high
performance computing facilities, e-libraries, virtual classrooms and very large databases.
