An Introduction to Uncertain Data Algorithms and Applications [chapter]

Charu C. Aggarwal
2009 Advances in Database Systems  
As a result there is a need for tools and techniques for mining and managing uncertain data.  ...  In recent years, uncertain data has become ubiquitous because of new technologies for collecting data which can only measure and collect the data in an imprecise way.  ...  The US and UK governments are authorized to reproduce and distribute reprints for Government purposes.  ...

Increasing representational power and scaling reasoning in probabilistic databases

Amol Deshpande
2010 Proceedings of the 13th International Conference on Database Theory - ICDT '10  
Increasing numbers of real-world application domains are generating data that is inherently noisy, incomplete, and probabilistic in nature.  ...  Unlike the other recent work on probabilistic databases, PrDB is designed to represent uncertain data with rich correlation structures, and it uses probabilistic graphical models as the basic representation  ...  I will use the PrDB probabilistic data management system being developed at the University of Maryland as a case study for this purpose [4, 7, 12] .  ...

2015 Proceedings of the International Association of Hydrological Sciences  
In fact, the forecasting services, the municipalities, and the civil security have difficulties in running and interpreting data-consuming models in real-time, above all if data are uncertain or non-existent  ...  These tools aim at planning real-time decisions given little, changing, and uncertain information available, which are: (i) a hydrological graphical tool (abacus) to estimate flood peak discharge from  ...  ), and the municipalities of Reynes (66), Saint-André (66) and Mireval (34) for their experience feedback.  ...

Trajectory Data Fuzzy Modeling : Ambulances Management Use Case

Eya Errajhi
2014 International Journal of Database Management Systems  
Data captured through mobile devices and sensors represent valuable information for organizations. This collected information comes in huge volume and usually carry uncertain data.  ...  In this paper, we will show the benefits of fuzzy logic in solving the challenges related to mobility data by integrating fuzzy concepts into the conceptual and the logical model.  ...  In order to deal with complex objects and imprecise and uncertain information in conceptual data modeling, one needs fuzzy extension to conceptual data models, which allow imprecise and uncertain information  ...

Drawing the Gaps: Graphical Methods for Representing Geospatial and Temporal Uncertainty with Cultural Artifacts [article]

Laura C. Trutoiu, Caitlin Ownby, Peter Shirley, William Thompson
2008 International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments  
We then argue that the 3D display in GIS system should use specific graphical styles to depict different types of data uncertainty.  ...  Representing uncertain data in the same context with accurate data requires contrasting between the two as well as keeping the representation as perceptually facile as possible.  ...  It is natural to expect the capability for 3D browsing of locations on the Earth in any time period. Source data is often incomplete, contradictory, or otherwise uncertain.  ...

S. J. Murray, A. D. Smith, J. C. Phillips
2012 Weather and forecasting  
Improvements are made to the index through incorporation of parameter uncertainties, managing data absence, and clearer graphical communication.  ...  The motive for proposing these changes is to better inform flood managers during the development of a flash flood that may require an emergency response.  ...  APPENDIX Data Communication The technique outlined is advantageous largely due to its simplicity.  ...
