Solving problems raised by heterogeneous ontologies can be achieved by matching the ontologies and processing the resulting alignments. This is typical of data mediation in which ...
—We present the design and implementation of UDAE, a Universal Data Access Engine for wireless sensor networks. The UDAE allows developers to access data both locally and over th...
Studying the evolution of long lived processes such as the development history of a software system or the publication history of a research community, requires the analysis of a ...
We consider the view data lineage problem in a warehousing environment: For a given data item in a materialized warehouse view, we want to identify the set of source data items th...
We offer a solution to the type inference problem for an extension of Hindley and Milner's type system with generalized algebraic data types. Our approach is in two strata. T...
