22 SOBOLEO  SOBOLEO supports the development and refinement of living ontologies according to the principles of Ontology Maturing  SOBOLEO is a web-based system that enables groups of people to jointly structure information (web documents and people) in a domain
33MATURE - Continuous Social Learning in Knowledge Networks Annotate People & Search
44 SOBOLEO  SOBOLEO uses Simple Knowledge Organisation System Format for representing ontologies
55 SOBOLEO  SOBOLEO provides an architecture that enables diverse components (both remote and within SOBOLEO) to jointly work with living ontologies

99 Living Ontologies, Ontology Maturing & their Use Cases
1010 Living Ontologies & Ontology Maturing  Living Ontologies are ontologies that are • never finished • used and developed at the same time by the end users  We describe their engineering with the Ontology Maturing Process Model • understanding their development as a continuous and collaborative process embedded & interwoven with actual usages processes
1111 Use Case 1  A learning course that is jointly developing an understanding of a domain by creating an ontology and interlinking it with relevant documents  For this use case SOBOLEO is integrated with a discussion tool to support structured dialogs about ontology development and document annotations  SOBOLEO supports the management of ontology, documents and dialogs  The ontology is also evolving throughout its use – always reflecting the current knowledge of the course participants
1212 Use Case 2  A group of experts jointly collecting the state-of-the- art in a scientific domain (with links to both documents and experts)  Here too the ontology will constantly evolve to reflect both the knowledge of the experts as well as the current scientific consensus
1313 Use Case 3  An HR department organizing data about available experts through semantic people tagging  SOBOLEO supports maintaining a competency ontology and using this ontology to keep track of - and search within - the database of experts  The competency ontology is never really finished – as new possible skills are emerging all the time.
1414 SOBOLEO – Concepts and Architecture
1515 Concepts: Collaboration Spaces  A Collaboration Space is the virtual space in which collaboration between people with a shared goal takes place  Each Collaboration Space has one SKOS ontology and may have information about documents and experts that are annotated with this ontology  All information in a space is jointly edited by the members of this space  One SOBOLEO installation supports an arbitrary number of (completely independent except for user data) collaboration spaces  On the server each collaboration space is represented as one folder that can even be moved between SOBOLEO installations
1616 Concepts: Event Bus & Events  Technically each collaboration space is represented by an Event Bus component that manages the communication within the space  Different parts of the functionality are realized as services (both local within the server and remote) that are registered with the event bus  Communication within the space is organized around the concept of Events: • Command Events, Query Event, Notification Event  All events exist as Java & JavaScript objects, as XML serializations, and as SOAP methods • any remote clients can do arbitrary changes and receive notifications
1717 Example – Delete Concept 1. Delete-Concept command triggered by user interaction
1818 Example – Delete Concept 2. Event bus asks registered Ontologoy Management service to extend this command event with implied commands
1919 Example – Delete Concept 3. Event Permission – this tests the user credentials as well as the adherence to SKOS integrity constraints
2020 Example – Delete Concept 4. Command processors actually execute the change
2121 Example – Delete Concept 5. Result is sent back to the requester and all registered event listeners are notified of the changes that have been done
2222 A look at SOBOLEO‘s User Interface
2323 SOBOLEO User Interface  SOBOLEO has interfaces for • Editing SKOS ontologies • Annotating documents & people • Search • Browse documents & people • And much more (administration, people directory, people profiles, history display, dialog transcript view, gardening recommendations)  SOBOLEO is completely web-based (implemented as Java Servlets)  User interface implemented in GWT (runs as Java Script in browser)
