Overview • Collaboration in the Semantic Grid • CoAKTinG project • Tools • Meeting Replays • Ontology • Applicability to e-Learning • Conclusion ES_LAB, Inha University

Collaboration in the Semantic Grid • Collaboration as an activity can be seen as a resource in itself, which with the right tools can be used to enhance and aid future collaboration and work. • rich in detail, rich in structures • a process of creating structured knowledge from information • Sharing and re-using the knowledge among tools and agents in the semantic grid ES_LAB, Inha University

CoAKTinG project • Collaborative Advanced Knowledge Technologies in Grid • www.aktors.org/coakting • “The CoAKTinG Project aims to support and enhance e-Science collaborations.” • 2 year project - started June 2002: • Funded by UK e-Science Programme. • Involves a total of ~15 PIs, Researchers, Students. • The techniques and tools employed by CoAKinG have useful application in experimental-based collaborative learning paradigm adopted by the EleGI (European Learning Grid Infrastructure) project. • http://www.elegi.org/ ES_LAB, Inha University

CoAKTinG Tools : BuddySpace • Presence: “an aggregated view of an entity’s dynamically changing attributes”: • Availability (“I’m logged on for a videoconference”) • Preference (“Only my boss can interrupt me now”) • Capability (“My current device can accept video calls”) • Location (“I’m in Munich…urgent calls only”) • BuddySpace - Instant Messaging environment with both client and sever functionality extended to enhance presence awareness : • Awareness of people…and other resources. • Editable maps for better visualisation of presence. • Advanced group chat facilities with voting, attention meters… • Provides lightweight communications channel ES_LAB, Inha University

CoAKTinG Tools : BuddySpace ES_LAB, Inha University

CoAKTinG Tools : Compendium • Tool for real-time capture and visualisation of argumentation (“collective sense-making and group memory”). • Connecting ideas: visually, by sets, metadata and hypertext links. • Free-form and template-driven discussions. • Underlying XML representations ES_LAB, Inha University

CoAKTinG Tools : Compendium • meeting template ES_LAB, Inha University

CoAKTinG Tools : I-X • I-X technology provides an environment for handling issues, performing activities, placing constraints, etc. – http://i-x.info/ • Founded on generic <I-N-C-A> activity ontology. • CoAKTinG roles: • Support meeting environment set-up activities; • Support ‘meeting process’ activities; • Networked ‘To-Do’ lists for issue-handling and activity tracking.

CoAKTinG Tools : I-X Process Panel Domain Editor Map Tool Messenger I-Plan ES_LAB, Inha University

Meeting Replay • Ontology-based approach - annotation of streams allows synchronised playback, ‘smart’ navigation, etc… • Interlinks information using Semantic Web technologies. ES_LAB, Inha University

Compendium Replay …to Support and Enhance e-Science Collaborations awareness ofcolleagues’ ‘presence’ BuddySpace Access Grid Node virtual meetings mapping real time discussions/group sensemaking NetMeeting recovering information from meetings enacting decisions/coordinating activities synthesising artifacts I-X Tools ES_LAB, Inha University

Ontology • Key Contributions • - Support variable levels of formality in communication • - Real time semantic annotation of discussions • - Events ontology for e-Science collaboration • - Context-driven collaboration tools • the AKT Reference Ontology • The meeting event itself • Meeting attendees • Projects which are the subject matter of meeting • Document associated with the meeting, including multimedia ES_LAB, Inha University

Ontology • Extensions to support: • generation of multimedia presentations (e.g. millisecond representations of time) • meetings distributed across several (physical and virtual) locations • exhibition of information objects as events (e.g. slides; videos; documents) • meeting-specific (compound) information bearing objects (versions of resources used in meetings) • annotation events (e.g. verbal comments, creation of Compendium nodes) • http://www.aktors.org/coakting/resources/ontology/meeting ES_LAB, Inha University

Applicability to e-Learning • There are many similarities in supporting the collaborations involved in e-Science and e-Learning. • BuddySpace, to create a Virtual Community consisting the individuals. • Compendium to capture collective thinking who are physically distributed, and used to plan and structure, and access, other resource. • I-X Process Panels to plan and structure learning tasks, goals, and experiments, and provides a mechanism for tracking issues and tasks when part of a collaboration. • the Replay Tool which can be used to review results from collaborative experiments and tasks. ES_LAB, Inha University

Conclusions • Future works • Incorporating domain-specific ontologies • The management of the recorded metadata to facilitate replay • Security, digital rights management and consent for release of metadata ES_LAB, Inha University
