We develop the scheme of indefinite constraint databases using first-order logic as our representation language. When this scheme is instantiated with temporal constraints, the res...
Due to an increasing volume of XML data, it is considered prudent to store XML data on an industry-strength database system instead of relying on a domain specific application or...
Mashup Feeds is a system that supports integrated web service feeds as continuous queries. We introduce collectionbased stream processing semantics to enable information extractio...
In this paper, an algorithm for obtaining consistent answers to queries posed to inconsistent relational databases is presented. The algorith is proven to be sound, terminating and...
Abstract. In this paper, we present a theoretical foundation for querying inductive databases, which can accommodate disparate mining tasks. We present a data mining algebra includ...
