Unit 3: Representation of Knowledge

simple scalar messages Notes
adaptive interaction between elements
A biological neuron may have as many as 10,000 different inputs, and may send its output (the
presence or absence of a short-duration spike) to many other neurons. Neurons are wired up in
a 3-dimensional pattern.

Did u know? Real brains are orders of magnitude more complex than any artificial neural
network so far considered.
3.1.7 Mixed Approaches

Certainly, all previous mentioned ways can be combined. This combination represents a powerful
but complicated solution. The problem is the data exchange between the different methods.
Here potent interfaces must be created.

Self Assessment

State whether the following statements are true or false:
1. The KR cannot be made to be independent of the underlying knowledge model or
knowledge base system (KBS).
2. A knowledge representation (KR) is most fundamentally a surrogate.
3. Semantic nets are simple and easy to understand.

3.2 Knowledge Organization

Knowledge management has become such a hot topic that it has been dubbed the business
mantra of the 1990s (Halal, 1998). It primarily addresses the growing importance of knowledge
management for private sector organizations, but clearly knowledge-generating organizations
such as federal science management and research agencies can not only benefit from this literature
but also play a leadership role in furthering theory and practice in this area. Although, these
knowledge-oriented organizations have been in the business of creating and furthering
knowledge development, they have not necessarily developed and articulated a systemic
approach to knowledge management. This is a critical omission that should be corrected. Of all
the management topics of potential relevance to public science organizations, this may be one
of the most useful areas to pursue. Knowledge management is central to public science
organizations. Although, knowledge management has become a highly prominent topic, the
term remains rather ambiguous and controversial, impeding progress in articulating what
knowledge management entails and what knowledge-based organizations will look like.

!
Caution Many have questioned whether knowledge management is, or will ever become,
a useful concept with practical application; others proclaim it is already the pivotal driver
of organizational success and will only become more important in the future. The latter
point of view is persuasive, but there is a long way to go in clarifying and articulating the
concept of knowledge management.
