Self-learning Knowledge Models
Semantic knowledge models capture the expert and background knowledge about a particular domain and involved stakeholders, e.g. user profiles, medical knowledge, context, etc. This knowledge is then exploited by applications to offer personalized & context-aware intelligent services to the end-users. However, knowledge constantly evolves and new insights should be able to be incorporated in the knowledge model. Therefore, the main research objective of this track is to devise algorithms, platforms and techniques that enable self-learning and evolving knowledge models that accurately reflect a domain.
Specifically, our research efforts focus on the following three topics:
- Design of data mining techniques that allow to process and exploit the captured semantic data in order to discover new semantic links and concepts, e.g., using inductive logic programming or association rule mining.
- Design of algorithms and techniques that allow to exploit the semantics captured in knowledge models in order to improve the accuracy and performance of machine learning techniques, e.g., to boost learning speed and generalization capability, to enhance feature selection & extraction techniques, to improve model parameter initialization, etc.
- Design of platform and techniques that allow that support evolving knowledge models, supporting multiple views on a domain through probabilistic logics and reasoning.
- A participatory ontology engineering methodology that allows to accurately and incrementally construct knowledge models together with domain experts without requiring medical knowledge from them.
