10Why LUISA
- E-Learning
- Lately, the interoperability of learning
resources across different Learning Management
Systems (LMS) and Learning Object Repositories
(LOR) has considerably improved, thanks to the
notion of learning objects as digital reusable
pieces of learning activities and contents.
Learning Activity
Learning Content
Learning Management Systems
Learning Object Repositories
11Why LUISA
- But the current approach still lacks of
flexibility, because of - Adaptability of course composition and limited
re-usability of LOs across different process
contexts - Different metadata standards existing
Learning Activity
Learning Content
Learning Management Systems
Learning Object Repositories
12Why LUISA
- Semantic Web technology is able to provide the
required computational semantics for the
automation of tasks related to learning objects
such as selection or composition - Semantic Web enriches data structures used for
describing web contents - The use of Semantic Web Services enables
mechanization in service identification,
configuration, comparison and combination. - Semantic Web Services have the potential to
change our life to a much higher degree than the
current web has already done
13Why LUISA
- But current e-Learning approach does not profit
of semantic benefits - LO ontologies are just translations of LO
standards, not envisaged for automated behaviour - LORs are not equipped with semantic
representation - L(C)MS are not SWS-based solutions so they are
not able to take advantage of its technology
pros selection, location, composition and
negotiation of LOs.

14Why LUISA
-
- LUISA is in charge of exploiting the
advantages of a Semantic Web Service Architecture
within the e-Learning environment -
- LUISA addresses one essential problem the
location of (the appropriate) learning resources
for some given needs (of learners, instructors or
groups)

15Why LUISA
- By means of
- The development of a reference semantic
architecture for the major challenges in the
search, interchange and delivery of
learning objects in a service-oriented
context. - The technical description of the solution in
terms of current SWS technology - The provision of the ontologies, facilities and
components required to extend and enhance
existing learning technology systems with the
advanced capabilities provided by computational
semantics.

16LUISA OverviewOutcomes
LUISA is a European Comission FP6 funded
Specific Targeted Research Project
www.luisa-project.eu
17Outcomes
- A formal framework for the discovery, selection,
composition and negotiation of learning objects
using a semantic service-oriented substrate - A concrete Semantic Web Services Architecture
realising the framework - A learning object-oriented ontology specifically
targeted to the delegation of tasks to software - A new technique for the semantic, formal
annotation of learning objects beyond the filling
of metadata fields prescribed by standards. -
18Outcomes
- Creation of relevant learning scenarios to serve
as a blueprint for LUISA technology adoption and
also forevaluation purposes - Industrial Training Scenario
- Academic Learning Scenario
- The outcomes of LUISA are expected to make a
significant contribution to the automation of
learning technology systems beyond current
standards, increasing the capability to locate,
search and negotiate learning resources mediated
by semantic tools.
19LUISA OverviewObjectives
LUISA is a European Comission FP6 funded
Specific Targeted Research Project
www.luisa-project.eu
20Objectives
- LUISA main objective
- To exploit the advantages of a Semantic Web
Service Architecture in order to enrich and make
more flexible the processes of specifying,
discovering and composing learning needs in the
context of Learning Management Systems and
Learning Object Repositories - The enhanced architecture will open new
possibilities in the automation of learning
object discovery, selection, composition and
negotiation, within distributed service
architectures seamlessly integrated through
ontologies.
21Objectives
- To develop a Semantic Web Service-based
Architecture for Learning Object Discovery,
Selection, Negotiation and Composition. - To develop Semantic Learning Object Annotation
Techniques. Learning Objects can be effectively
disseminated by Semantic Web Services, whose
functional and non-functional characteristics
need to be described. - To develop an Annotation Tool. Our approach
requires the addition of semantics to learning
objects metadata, and for this sake, we will
further develop an authoring tool, extending
current ones.
22Objectives
- Integration of the architecture into existing
LCMS. The SWS infrastructure and the Annotation
tool have to be seamlessly integrated into
existing Learning Content Management Systems to
exploit the advantages of widely spread systems
in the e-learning community. - Case study reports. The implementation of the
architecture will be put into practice in
real-world case studies (one in the Academic
e-Learning and other in the Industrial
e-Training), converting existing learning
resources to the ontological representation,
serving both as a proof of concept for the
architecture in all of its scenarios, and also as
a vehicle to analyze empirical usage findings in
a real-world context.
23Objectives
- WSMO extension. From a methodological
perspective, LUISA is also a major validation of
the generic SWS infrastructure provided by other
initiatives as WSMO, especially due to the fact
that the domain of learning technology is
especially metadata-intensive, since it aims at
describing richer content structures and
pedagogical properties. Some of the components to
be developed under LUISA's performance are - An extension of WSMO to deal with LOMR
requirements. - An extension of WSMO to support the process
languages.
24LUISA OverviewInnovations and Benefits
LUISA is a European Comission FP6 funded
Specific Targeted Research Project
www.luisa-project.eu
25Innovations and Benefits
- LUISA addresses one essential problem the
location of (the appropriate) learning resources
for some given needs (of learners, instructors
or groups). - Two main approaches are available as of
today - Google!
- Specialized learning object repositories (LOR)
that provide search based on specialized
metadata. - But
- The first one does not exploit information
specific to learning/instruction. - The second one does (to some extent), but without
exploiting domain/commonsense/specialized
knowledge
26Innovations and Benefits
- LUISA is a framework for developing specialized
systems or brokers for other systems. - It does not replace but extends existing
investment - And provides several key innovations
- Enables the expression of queries in terms of
ontologies. - Locates the best sources/providers for given
queries (learning needs) - Suggests tentative compositions based on
learning needs - Is able of getting back to the user for more
relevant info - Enables different query resolution/composition
strategies, including educational knowledge
27Innovations and Benefits
- Shifting from manual data-oriented approach to
automatic service-based approach - Shifting decision about how to achieve the
learning objective from the learning designer
(design-time) to the SWS broker and the Service
(run-time) - Dynamic adaptation to actual learning context
(known at runtime only) - Decision based on formal semantics (not based on
the subjective of a specific designer) - Integration of wide variety of learning resources
(services, content, open repositories) - Reusability of semantic learning process models
across different contexts, standards and
platforms - Higher appropriateness of the learning support to
actual learning context - Reduces development costs

expecting innovative services that would really
enable easy description, retrieval, selection and
reuse of digital learning resources in an easy
way. - Objectives
- To devise realistic scenarios within different

delivery at runtime - Different web services used which retrieve
semantic LO metadata out of virtual different
repositories - Dependent of provided search parameters
appropriate service is selected(e. g. Field of
Study, Language, Interactivity Type) - Dynamic selection of appropriate service based on
semantic capability descriptions (WSMO) - Available at http//luisa.open.ac.uk/test/
- Scenario 2 Highly adaptive and
standard-compliant learning packages - One unique IMS Content Package (IMS LD) reused
across different learning contexts - Different learners supported by achieving his/her
different objectives (e. g. Learn German,
Learn Italian ) - Individual learner preferences (e. g. native
language) are considered at runtimefor the
dynamic service selection (e. g. french learners
get french learning content )
