Automated Assessment of Aggregate Query Imprecision in Dynamic Environments [chapter]

Vasanth Rajamani, Christine Julien, Jamie Payton
2009 Lecture Notes in Computer Science  
We define the semantics of aggregate queries in terms of a qualitative description of consistency and a quantitative measure of imprecision.  ...  The protocol enables intuitive interpretations of the semantics associated with an aggregate query's execution in a dynamic environment.  ...  The conclusions herein are those of the authors and do not necessarily reflect the views of the sponsoring agencies.  ...

Viewpoints on Emergent Semantics [chapter]

Philippe Cudré-Mauroux, Karl Aberer, Alia I. Abdelmoty, Tiziana Catarci, Ernesto Damiani, Arantxa Illaramendi, Mustafa Jarrar, Robert Meersman, Erich J. Neuhold, Christine Parent, Kai-Uwe Sattler, Monica Scannapieco (+3 others)
2006 Lecture Notes in Computer Science  
We introduce a novel view on how to deal with the problems of semantic interoperability in distributed systems.  ...  This view is based on the concept of emergent semantics, which sees both the representation of semantics and the discovery of the proper interpretation of symbols as the result of a self-organizing process  ...  Imperfect Information in Emergent Semantics Representing Imperfection Emergent semantics processes need ways of representing and assessing imperfection in order to dynamically refine semantic agreements  ...

Begum Ilke Zilci, Mathias Slawik, Axel Kupper
2015 2015 26th International Workshop on Database and Expert Systems Applications (DEXA)  
One of the most important use cases is service requesters with limited technical knowledge who need to compare services based on their QoS requirements in cloud service marketplaces.  ...  Service matching concerns finding suitable services according to the service requester's requirements, which is a complex task due to the increasing number and diversity of cloud services available.  ...  INTRODUCTION The increasing number and diversity of services available in the cloud computing environment causes the service selection to become more complex.  ...
