Types of Knowledge

Explicit or documented Knowledge Also known as
formal Knowledge
Tacit or undocumented Knowledge also known as
Informal Knowledge

3
Explicit knowledge

Documented and formal
Easier to identify
Re-usable
Can be captured and stored
Can be identified, measured, distributed and
audited

4
Tacit knowledge

Undocumented and informal
Exist in people minds
Personal, context-specific
Intuitions, mind-sets, Experiences, Skills,
Competencies
Hard to capture

Questions
Can organizations collective knowledge be tapped
and managed to improve the overall
competitiveness of the organization?
What is the role of technology in knowledge
management?
How can we use technology to help in managing
tacit knowledge?
What is the role of portals in KM?

Portals

A Web portal (or simply a portal) is a cyber
door on the Web it serves as a customizable
home-based from which users do their searching,
navigating, and other web-based activity
(Schneider Perry, 2000).

Portals

Web portals is the term that generally
confuses people. The question will be what
exactly is a web portal? Yahoo!, ICQ.com,
eBay.com and Amazon.com are but just a few to
start them off with. They may not realize that
corporate websites, intranets or extranets are
built as portals. Most of the portals today use
the web as the primary platform, therefore any
portal that is web-based may very well be a web
portal.

Web Portals

A Web site or service that offers a broad array
of resources and services, such as e-mail,
forums, search engines, and on-line shopping
malls. The first Web portals were online
services, such as AOL, that provided access to
the Web, but by now most of the traditional
search engines have transformed themselves into
Web portals to attract and keep a larger
audience.

Portals

Portals go by various names.
The terms that are floating around are enterprise
portals, EKPs, EIPs, knowledge portals, corporate
portals, internet and web portals, marketplace
portals, and workspace portals

11
Portal Structure

A generic portal structure houses several
components, namely taxonomy, metadata, search,
integration, publishing, and presentation
engines. Out of these, the key components are
taxonomy, integration and metadata, which has to
do with the organization, indexing and
categorization of information.

Knowledge Organization- Directories
Classifying Information according Categories
A flat or Hierarchy of related objects
Directory structures are not as deep and
consistent as a classification scheme or a
taxonomy system.
Examples include categories used by Yahoo,
Excite, and Lycos.

Classification Schemes
Tools for organizing information resources in a
systematic, logical and practical means, mostly
according to their subject contents.
The subject classification is standardized and
arranged in a well-thought out disciplinary
context.
Classification Schemes represents concepts and
ideas and not merely links.
Examples of major classification schemes include
LCCS, DDC, and UDC.

K-Organization-Taxonomies
Organization systems that maps information into a
fixed or dynamic structures
Taxonomy is a classification system that provides
a systematic representation of knowledge
It is the creation of structure (arrangement) and
labels (names) to aid location of relevant
information.
A uniform scheme of labeling or tagging
information resources in an organization to map
knowledge resources.
Examples include taxonomies used by Microsoft and
Ernst and Young

K-Organization-Ontology
Automated organization structure similar to
taxonomies
It has deeper semantics for class and cross-class
relationship, and share-ability of the
ontological construction heterogeneous systems.
Uses thesauri and other indexing tools to
generate structure that enables users to navigate
up and down from one related topic to another.

K-Organization-Taxonomies
provide the categorization model that facilitates
efficient searching, browsing, and alerting.
provide a knowledge map to facilitate navigation
of the intellectual capital of the enterprise.
Taxonomies could facilitates use of tacit
knowledge.
Improve organization Workflow and streamline
operations
Improve flow of information and communication

K-Organization-Taxonomies
Building taxonomies might not be easy and
requires deep thinking
Building taxonomies using an automated process
(Ontology)
Building taxonomy manually using a list of terms,
subject heading and so on
Use a hybrid approach

K-Organizations-Taxonomy Tools
Autonomy (provides a mechanism for automatic
classification, tagging and hyper-linking online
content)
Semio (Builder Product and Topic Library)-
performs a three-step process text collection
from networked sources, phrase extraction, and
attaching these to categories.
