3. Knowledge Management
Knowledge Management (KM) refers to a range of practices used by organisations to identify, create, represent, and distribute knowledge for reuse, awareness and learning across the organisation.
Knowledge Management programs are typically tied to organisational objectives and are intended to lead to the achievement of specific outcomes such as shared intelligence, improved performance, competitive advantage, or higher levels of innovation.

4. Explicit Knowledge
Explicit knowledge is knowledge that has been or can be articulated, codified, and stored in certain media. The most common forms of explicit knowledge are manuals, documents, procedures, and stories. Knowledge also can be audio-visual. Works of art and product design can be seen as other forms of explicit knowledge where human skills, motives and knowledge are externalized

5. Implicit Knowledge
The knowledge that people carry in their heads. Compared with explicit knowledge, implicit knowledge is more difficult to articulate or write down and so it tends to be shared between people through discussion, stories and personal interactions. It includes skills, experiences, insight, intuition and judgement.
There are authors that make a difference between Implicit Knowledge (a knowledge that through indirect mechanisms should be made explicit) and Tacit Knowledge (the one that resides in the head of the humans and that cannot be made explicit in anyway).
Example of Tacit Knowledge. A expertise in a machine is able to locate a problem faster that a junior one even if they use the same procedures (if they have at their disposal the same explicit knowledge)

6. Knowledge Management Tools
There are commercial tools that are announced as Knowledge Management Systems (KMS) but they don’t cover all the aspects of KM specially regarding implicit knowledge.
The objective of this session is to explain the alternatives/extensions to this commercial tools using Open Source that combined can create a powerful taylor-made KMS

Access to information is possible though several mechanisms as:
Metadata Exchange Protocols (OAI, Z93.50)
Query Languages (SQI)
Web Services
Syndication (RSS/Atom)

23. Explicit Knowledge (P2P Networks) 1/2
A Peer-To-Peer computer network relies primarily on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers.
P2P networks are typically used for connecting nodes via largely ad hoc connections. Such networks are commonly used for sharing contents but can be also used for transmit realtime data, such as telephony traffic

26. Implicit Knowledge (Virtual Communities)
Virtual communities form "when people carry on public discussions long enough, with sufficient human feeling, to form webs of personal relationships"
A virtual community or online community can be used loosely for a variety of social groups interacting via the Internet. It does not necessarily mean that there is a strong bond among the members
It is supported by a variety set of communication tools as forums, chats or CMS
Interactions within the communities allows organisations to make explicit some implicit knowledge as:
Discover experts as the people that becames a reference in the community
Qualify contents through Rating/Voting processes
Define Ontologies through the tagging of contents by the members of the community (folksonomies)

27. Implicit Knowledge (Tagging/Voting)
Digg is a community-based popularity website with an emphasis on technology and science articles. It combines social bookmarking, blogging, and syndication with a form of non-hierarchical, democratic editorial control. News stories and websites are submitted by users, and then promoted to the front page through a user-based ranking system. This differs from the hierarchical editorial system that many other news sites employ.

28. Implicit Knowledge (Social Networks)
A social network is a social structure made of nodes which are generally individuals or organizations. It indicates the ways in which they are connected through various social familiarities ranging from casual acquaintance to close familial bonds.
Social Networks make explicit the implicit relations among the people.

30. Implicit Knowledge (Knowledge Map)
Taxonomy: the practice and science of classification.
Folksonomy: An Internet-based information retrieval methodology consisting of collaboratively generated, open-ended labels that categorize content such as Web pages, online photographs, and Web links. A folksonomy is most notably contrasted from a taxonomy in that the authors of the labeling system are often the main users (and sometimes originators) of the content to which the labels are applied. The labels are commonly known as tags and the labeling process is called tagging.
Ontology: It seeks to describe or posit the basic categories and relationships of being or existence to define entities and types of entities within its framework.
KNOWLEDGE MAP: Taxonomy where the knowledge of a certain community are clasiffied .

31. Implicit Knowledge (LSA/LSI)
LSA is an algorithm that makes automatic the process of creating ontologies from specific contents to, for example, allow them to be classified in a taxonomy (or in the knowledge map of an organisation).
Latent Semantic Analysis : LSA uses a term-document matrix which describes the occurrences of terms in documents. Your original matrix gives the relationship between terms and documents. Latent semantic analysis transforms this into a relationship between the terms and concepts, and a relation between the documents and the same concepts. The terms and documents are now indirectly related through the concepts.

Open source program for latent semantic indexing

32. Implicit Knowledge (Best Practices)
Best Practice is a management idea which asserts that there is a technique, method, process, activity, incentive or reward that is more effective at delivering a particular outcome than any other technique, method, process, etc. The idea is that with proper processes, checks, and testing, a project can be rolled out and completed with fewer problems and unforeseen complications.
