Automated Assessment of Aggregate Query Imprecision in Dynamic Environments
[chapter]
2009
Lecture Notes in Computer Science
Preserved Fulltext
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. ...

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. ...
