-- In this paper, we put forward our approach for answering aggregated queries over imprecise data using domain specific taxonomies. A new concept we call the weighted hierarchical...
Query rewriting using views is an essential issue in data integration. A number of algorithms, e.g., the bucket algorithm, the inverse rules algorithm, the SVB algorithm and the M...
Abstract. We provide a general and modular framework for describing inferences in Answer Set Programming (ASP) that aims at an easy incorporation of additional language constructs....
Abstract. Straight-line programs (SLPs) offer powerful text compression by representing a text T[1, u] in terms of a restricted context-free grammar of n rules, so that T can be r...
The problem of information integration is discussed in the context of answering a query over the web. Querying the web requires that information from different web and other sourc...
