Journal ArticleDOI
A survey of context modelling and reasoning techniques
Claudio Bettini,Oliver Brdiczka,Karen Henricksen,Jadwiga Indulska,Daniela Nicklas,Anand Ranganathan,Daniele Riboni +6 more
TL;DR: The requirements that context modelling and reasoning techniques should meet are discussed, including the modelling of a variety ofcontext information types and their relationships, of situations as abstractions of context information facts, of histories of contextInformation, and of uncertainty of context Information.
Book ChapterDOI
Protecting privacy against location-based personal identification
TL;DR: It is argued that even if the user identity is not explicitly released to the service provider, the geo-localized history of user-requests can act as a quasi-identifier and may be used to access sensitive information about specific individuals.
Journal ArticleDOI
COSAR: hybrid reasoning for context-aware activity recognition
Daniele Riboni,Claudio Bettini +1 more
TL;DR: This paper proposes a solution based on the use of ontologies and ontological reasoning combined with statistical inferencing to recognize complex activities that cannot be derived by statistical methods alone.
Book
Time Granularities in Databases, Data Mining, and Temporal Reasoning
TL;DR: This book deals with several aspects of temporal information and provides a unifying model for granularities and is intended for computer scientists and engineers who are interested in the formal models and technical development of specific issues.
Journal ArticleDOI
An access control model supporting periodicity constraints and temporal reasoning
TL;DR: An access control model in which periodic temporal intervals are associated with authorizations is presented, which provides a high degree of flexibility and supports the specification of several protection requirements that cannot be expressed in traditional access control models.
