Uncertain Databases in Collaborative Data Management

چکیده
We discuss an approach to collaborative data management based on uncertain databases. Note that, in a collaborative data management system, users may have contradicting opinions about the correct values of data items. In our approach, we propose to store all conflicting data versions in parallel and to resolve conflicts based on user ratings. We show that such a collaborative data management system can be nicely represented in an uncertain database using U-relations.

Research Statement - Nilesh Dalvi
My research is driven towards developing efficient and scalable techniques for the management of probabilistic data, with the goal of dealing with the uncertainty inherent in modern data applications. There is a thrust for uncertainty management in databases, driven by the convergence of two factors. The first factor is a pull from applications. Databases are going through an exciting time wher...
متن کاملDisTriB: Distributed Trust Management Model Based on Gossip Learning and Bayesian Networks in Collaborative Computing Systems
The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...

متن کاملManaging Continuous Uncertain Data by a Probabilistic XML Database Management System
Database systems are widely used in today’s world. Almost every information system contains one or more databases. From a traditional perspective, databases are used to store precise values about objects in the ’real world’. However, many information is uncertain or imprecise. Consider, for example, sensor applications. Sensors produce uncertain and imprecise data since readings of sensors are ...
متن کاملOn Uncertain Probabilistic Data Modeling
Uncertainty in data is caused by various reasons including data itself, data mapping, and data policy. For data itself, data are uncertain because of various reasons. For example, data from a sensor network, Internet of Things or Radio Frequency Identification is often inaccurate and uncertain because of devices or environmental factors. For data mapping, integrated data from various heterogono...
