The problem of extracting consistent information from relational databases violating integrity constraints on numerical data is addressed. In particular, aggregate constraints defined as linear inequalities on aggregate-sum queries on input data are considered. The notion of repair as consistent set of updates at attribute-value level is exploited, and the(More)

On the Complexity of Probabilistic Abstract Argumentation 1 / 24 Introduction Background Complexity results Conclusions and future work Motivation Contribution Argumentation in AI A general way for representing arguments and relationships (rebuttals) between them It allows representing dialogues, making decisions, and handling inconsistency and uncertainty(More)
An architecture is proposed providing robust data acquisition facilities from input documents containing tabular data. This architecture is based on a data-repairing framework exploiting integrity constraints defined on the input data to support the detection and the repair of inconsistencies in the data arising from errors occurring in the acquisition(More)
A probabilistic framework is introduced for reducing the inherent uncertainty of trajectory data collected for RFID-monitored objects. The framework represents the position of an object at each instant as a random variable over the set of possible locations. The probability density function of this random variable is initialized according to an a-priori(More)
Though there is much work on how inconsistency in databases should be managed, there is good reason to believe that end users will want to bring their domain expertise and needs to bear in how to deal with inconsistencies. In this paper, we propose the concept of inconsistency management policies (IMPs). We show that IMPs are rich enough to specify many(More)
Both studies on animals and humans suggest the presence of dopamine (DA) receptors in the anterior segment of the eye. Their role in the dynamics of intraocular pressure (IOP) is not yet clear. DA2 and DA3 receptors are mainly located on postganglionic sympathetic nerve endings. Their stimulation reduces the release of norepinephrine and suppresses the(More)
