This publication constitutes the refereed court cases of the 1st foreign convention on Scalable Uncertainty administration, SUM 2007, held in Washington, DC, united states, in Oktober 2007.

The 20 revised complete papers awarded have been conscientiously reviewed and chosen from quite a few submissions for inclusion within the ebook. The papers tackle synthetic intelligence researchers, database researchers, and practitioners to illustrate theoretical thoughts required to regulate the uncertainty that arises in huge scale genuine global purposes. The papers take care of the next subject matters: uncertainty versions, probabilistic logics, fuzzy logics, and annotated logics, inconsistency logics, database algebras and calculi, scalable database structures, spatial, temporal, cellular and multimedia databases, in addition to implementations, and applications.

He discusses key subject matters reminiscent of: the right way to be certain a knowledge concept version; its use in exploratory learn; and the way it compares with different methods equivalent to community research, course research, chi sq. and research of variance.

As a result of this operation, a modification to the old version of the tuple is needed by changing some of the parameters that define it. As a consequence of our approach, the queries return a set of tuples together with a fulfillment degree when a query A Fuzzy Set-Based Approach to Temporal Databases 43 is made on these fuzzy temporal data. The paper also analyzes the different types of queries that can be made on these data. ) and considering a wider range of temporal data. We are also studying the problem of primary keys in the presence of fuzzy intervals instead of VST and VET attributes and trying to find out new indexing techniques that take the new primary keys into account.
