After the Twente Data Management workshop on Uncertainty in Databases held at the university of Twente in June 2006, the speakers and participants expressed their wish for a workshop on the same topic ...
This Management of Uncertain Data workshop, colocated with the international conference on Very Large DataBases (VLDB) is the result of this wish. We received 9 submissions from all over the world. ...
Because "exact" aggregation in uncertain databases can produce exponentially-sized results, we provide three alternatives: a low bound on the aggregate value, a high bound on the value, and the expected ...

Projections of shoreline retreat are highly uncertain, however, namely due to deeply uncertain mean sea level projections and the absence of consensus on a coastal impact model. ...
This framework builds upon an empirical shoreline change model to which we ascribe possibility functions to represent deeply uncertain variables. ...
This is not always the case and depends on the characteristics (like the monotony) of the mathematical function optimised at step 3 (given the fixed value). ...

The recognition of the patient's behavior when he carries out some activities in a smart home is primordial in order to give adequate assistance at the opportune moment. ...
To address this challenging issue, we present a formal activity recognition framework based on possibility theory and description logics. ...
We propose a formal framework for activity recognition based on description logic and possibility theory, which transforms the recognition problem into a possibilistic classification of activities. ...

However, choice of suitable method(s) for a given experimental dataset is not straightforward. Common approaches do not translate well and fail to take account of the data profile. ...
The result is dependent on the order of input as once initial cluster structure is obtained, a vertex v is moved to that cluster for which it has a higher affinity value. ...
