Ontology-based situation recognition for context-aware systems

Judie Attard, Simon Scerri, Ismael Rivera, Siegfried Handschuh
2013 Proceedings of the 9th International Conference on Semantic Systems - I-SEMANTICS '13  
An ontology-based graph matching technique continuously compares a person's 'live context', with all previously-stored situations, both of which are represented as an instance of the DCON Context Ontology  ...  In this paper we present the matching technique employed to enable automatic situation recognition, and an experiment to evaluate its performance based on real users and their perceived context data.  ...  CONCLUSION In this paper we presented an ontology-based situation recognition technique that can be employed by any context-aware system that is capable of extracting information corresponding to the concepts  ...
