What is an Ontology?
„ …ontologies aim to capture consensual knowledge in a generic and formal way, so that they may be reused and shared across applications (software) and by groups of people. Ontologies are usually built cooperatively by a group of people in different locations.”
(Corcho et al., 2003. p. 44.).

Curricula Development
• Different types of connections between the nodes
• Learning Content is developed in Semantic MediaWiki
• Example: Studio MediaWiki

Adaptive Testing• Questions are connected to the Ontology nodes
• Test engine is adaptive: continuously monitors students’ performance
• A Built-in reasoning engine identifies the missing knowledge areas
• Knowledge areas are only accepted if questions about underlying concepts are correct
• Based on this information content is offered automatically
• Demo Video
• Interactive Web Demonstration

Learning Technology Selection
• Based on the Ontology for the E-learning Manager Course
• Technology requirements of eLearning delivery havebeen identified
Learning Technology Selection
• For investments seamless set of technological criteria is now available
• This approach has been tested on institutional synchronous virtual learning software selection

HRM Selection and Recruitment
HRM Selection and RecruitmentThis ontology based system has the potential to be powerful tool
to:
• 1) select job applicants,
• 2) train job incumbents,
• 3) assess job performance,
• 4) map an organization’s human capital in light of strategic workforce planning considerations

Context Sensitivity (Contsens)
• The mobile device is a sensor:Location
Identity
Surroundings of the learner
Amount of light
Biophysical reactions of the learner
Etc…
• Based on this complex measurement, content is delivered automatically
Contsens Project
Contsens Project
• Flash Based application –as an external module
• 4 different courses (two art ourses, IT, language learning)
• Content delivery based on user profile and location
• project website: www.ericsson.com/contsens
