In this paper, we address the problems of using discovered rules for query answering, and then propose algorithms for rewriting, applying and maintaining these ...

Abstract. Research has been done in discovering rules from databases and in applying these rules to intensional answers to database queries, semantic query ...

Query answering using discovered rules. Chen I.-. Expand. Publication type: Proceedings Article. —. DOI: 10.1109/icde.1996.492189. Copy DOI. References 8.

We present a description of the PhD thesis which aims to propose a rule-based query answering method for relational data. In this approach we use an additional ...

This paper provides an introduction to ontological query answering with ex- istential rules. In Section 2, we present basic logical foundations for representing.

In this paper, we fill the gap by proposing an efficient datalog rewriting ap- proach for answering conjunctive queries over ex- istential rules, and identify ...

The problem of answering queries using views is to find efficient methods of answering a query us- ing a set of previously materialized views over the.

In this paper, we propose a new powerful rule query language Rule-QL for querying multiple rulebases that is modeled after SQL and has rigorous theoretical.

We introduce a new concept of an answer for a query which includes both atomic facts and general rules. We provide a method of transforming rules by relational ...

We introduce two new inconsistency-tolerant semantics for answering Boolean CQs (BCQs) under existential rules, called the GR and the LGR semantics, which gen-.
