Outline
– Knowledge Sharing and Management, in
relation with…
• Emerging need
• TENCompetence approach
• Initial proposal
Why Knowledge Management?
– Quick changes, which are normal in the modern society as well
as in market’s strategic directions, may result in the loss of
knowledge in specific areas.
– Need of increasing competitiveness
– Rising in innovation rate
– Competitive pressure reduce the amount of people that holds
valuable knowledge
– Nowadays less time is available to experience and acquire
knowledge
– There is a need to manage increasing complexity
– Early retirements and increasing mobility of workers lead to loss
of knowledge
– More and more informal knowledge has to be replaced with
formal methods
Moreover ….
– Most of human activities, as well as many
aspects affecting normal life, are heavily
information and knowledge-consuming
• Products and services are increasingly complex
• Products and services are endowed with a
significant information component
– Organizations compete on the basis of
knowledge
– Life-long learning is more and more an
inescapable real and urgent need.
Knowledge Resource Sharing &
Management in TENCompetence
Main objective of WP5 is to make available an infrastructure suitable to
manage and share any kind of information produced and exchanged
within the TENCompetence system
Expected results:
– A standards-based set of components supporting the creation, storage,
use, reuse and exchange of knowledge resources
– An embedding of these components in an environment of many
thousands of knowledge resources available in a variety of repositories
– A set of rating and recommending systems (based on collaborative
filtering techniques) allowing users of knowledge resources to feedback
information on their quality into the competence development network
– A set of reward mechanisms able to be tuned in order to stimulate the
following of the policies (e.g. policies fostering knowledge resources reuse vs. new development)
– A (light-weight) profile of specifications and standards to facilitate
Knowledge Resource Sharing & Management
Major foreseen features
• Creation of knowledge resources (KR)
• Unique identification and indexing of KR through
metadata (LOM, Dublin Core, etc.)
• Packaging of KR according to IMS-CP and/or SCORM
specifications)
• Storage of KR in distributed and federated digital
repositories
• Search and retrieval of KR
• Reuse and sharing of KR
• Quality rating of KR
“Material” Knowledge Resources
In this category the most traditional kinds of multimedia resources can be listed:
–
text and hypertext (txt, doc, rtf, pdf, html, etc.)
–
images and 2D graphics (tiff, jpg, png, gif, .etc.)
–
3D graphics (cad, X3D, VRML, etc.)
–
audio (wav, mp3, etc.)
–
video (mpeg, avi, mov, qt, etc.)
–
animations (dir, osx, swf, etc.)
Additionally, also the following heterogeneous resources can be collected under
this category:
–
planning and design (mpp, etc.)
–
resources descriptors (xml, rdf, etc.)
–
references (libraries, publications, etc.)
–
executable programs (exe, etc.)
–
libraries (dll, etc.)
And also …
More specifically for e-learning in general and for
TENCompetence in particular, as already highlighted
previously we could also consider at least:
– metadata and related vocabularies
– learning objects
– learning courses
– units of learning
– units of assessment
– learning activities
– learning paths
– learning networks
“Immaterial” Knowledge Resources
Within this category some resources can be grouped
that are normally underestimated :
– Human resources (e.g. a projection of personal skills, acquired
competencies, personal abilities, natural capabilities, personal
field expertise)
– Human Area Network (HAN) resources, i.e. communities of
connected human beings and mobile terminals and devices
(e.g. RedTacton)
– “Environmental” resources (e.g. organizational know-how,
training and lifelong learning policies at European/National/local
level).
These will require a specific effort to be properly
modeled and are currently under investigation.
Research on models and methods
• Suitable policies to promote the creation and exchange of
knowledge resources need to be defined.
• Tools able to analyze tracking data in order to proactively suggest
knowledge resources:
– by extending the description of KR in order to provide more powerful
selection features.
– by classifying KR from sources where classification is not available.
• Once strategies for facilitating KR exchange have been defined,
they have to be made available by WP5 by means of proper
services (e.g. exploiting location-based information and users
position-based knowledge exchange).
• An important aspect is the introduction of the social dimension, for
instance through the recording of multi-user interactions in order to
stimulate further interactions.
KRMS Service Architecture
• The KRMS Service will provide other modules
and services in the system with functionalities for
managing and sharing KR
• The KRMS Service will be accessed through a
limited number of well specified interfaces (e.g.
users, TENCompetence client, UoL&LA Service)
• Internally the KRMS Service will have a serviceoriented architecture suitable to support the
requested features
• The idea is to design an "abstract" architecture
and then to match the identified services to
existing components.

Indexing and Metadata
• At each level the knowledge resources will be provided with the
proper metadata in order to support the specific searches. This
should allow supporting some semantic at each level (learning units,
learning paths, etc.).

Object
Generic P2P Architecture
• a central Index server:
• it does not contain files physically
• It only maintains the information about users who are logged on to the
network, the IP address of the client and the list of files shared at any given
moment by a user
LionShare (1)
• The LionShare P2P project is an effort to facilitate legitimate filesharing among individuals and educational institutions around the
world
• In the role of provider, LionShare developed a Repository OSID that
provides access to content on their Peer-to-Peer (P2P) server
network. This allows application such as Sakai, Tufts University’s
Visual Understanding Environment (VUE), and others to access
content on the server network for no additional development effort
beyond their initial adoption of OSIDs
• In the role of consumer, LionShare’s desktop client application can
include any Repository OSID implementation as part of a federated
search.
• By embracing the OSIDs, applications gain access to more content
and content providers gain a wider market, all at a low marginal cost

Integration in the TENC system (2)
• The clients of this Network are:
• KMS (Lex, DSpace): can do search and also
optionally share Knowledge Resources
• Generic Digital Repositories (Ariadne, Merlot,
etc.): can only share resources
• Any client of the P2P network must have two OSID
DR Implementations:
• one used for the connection to P2P network; it
MUST be a common implementation for all clients
• one used to access Local Repositories: it should
be a customized implementation for every client
type
