SELBO
SCORM Editor for eLearning Based on Ontologies
Part of eLSE projectDamyan Mitev
University of Plovdiv “Paisii Hilendarski”
What is SELBO
• SELBO is an editor, specialized in creating eLearning content.
• SELBO generates SCORM 2004 compliant HTML content.
• SELBO uses ontologies (via the core API of Protégé) to help content creators in designing their electronic lessons.
• SELBO integrates JADE agents to help content developers.
Design goals
• Generation of standard eLessons.
• Easy to use by non-professionals in computer science.
• The user works with the terms in his domain of occupation and doesn’t have to have any knowledge of SCORM or HTML.
Standards used in SELBO
• SCORM
• Protégé ontologies
• HTML and JavaScript (Ekit Library)
• JADE Agents
Why SCORM
• SCORM is international standard for eLearning.
• It not only standartizes the means of generating, packaging and playing the eLesson, but also has a means for defining sequencing and navigation of the content on per-student basis.

Why ontologies
• An ontology is a knowledge base.
• It gives the content developer premade definitions of concepts in given domain.
• Content developer works with the terms of the ontology, isolated from the internal representation of these terms.
Why HTML
• HTML is a mature standard for visualization of multimedia content.
• HTML pages can be visualized with any modern browser – no need for special third party client applications.
• If desired, it is possible some part of a page to be generated by third party HTML editor.

Why Agents
• An agent is a intelligent piece of software.
• It can track content developer’s actions, guess his intentions and offer assistance.
• An Agent may search for a given concept in the ontology on behalf of the developer.
• It may even communicate with other agents to gather extra resources on the topic of the eLesson.

Future Plans
• Utilization of higher level of S&N templates and scenarios with explicitly defined semantics
• Adding of new agents with dialog based interaction with the user goal driven behaviours, that follows the goal
of the selected template
• Enhancing the multimedia support• Test creation module• Integration with the S-Bahn Tool
