2018-03-17 · Duplicates in data management are common and problematic. In this work, we present a translation of Datalog under bag semantics into a well-behaved extension of Datalog, the so-called {\\em warded Datalog}$^\\pm$, under set semantics. From a theoretical point of view, this allows us to reason on bag semantics by making use of the well-established theoretical foundations of set semantics. From

In this article, we propose and study a bag semantics for OBDA which provides a solid foundation for the future study of aggregate and analytic queries. Moreover, since real SQL requires a richer semantics than set semantics, there has been work on bag-semantics for SQL, essentially by introducing an interpreted column. One important technique for reasoning about query containment in the context of bag semantics is to translate the queries to alternatives using aggregate functions and assuming set semantics. Bag Semantics Chaudhuri& Vardi–1993 Optimization of Real Conjunctive Queries Called for a re-examination of conjunctive-query optimization under bag semantics. In particular, they initiated the study of the containment problem for conjunctive queries containment under bag semantics.

Difference between a bag Semantics and a set semantics? A bag is an unordered collection of items where identical items may appear multiple times. av A Andrejev · 2016 · Citerat av 2 — Semantic Web and Linked Open Data provide a potential platform for interoperability of semantics, which governs the evaluation of bag-valued functions. “contents” are sets of tuples (set semantics).

Motivated by the need for OBDA systems supporting database-style aggregate queries, we propose a bag semantics for OBDA, where duplicate tuples in the views defined by the mappings are retained, as is the case in standard databases. We show that bag semantics makes conjunctive query answering in OBDA coNP-hard in data complexity.
The bag semantics we consider in this article generalises the bag-set semantics, and restricting ourselves to bag-set semantics would not change any of our results. bag semantics makes conjunctive query answering in OBDA CONP-hard in data complexity. To regain tractability, we consider a rather general class of queries and show its rewritability to a generalisa-tion of the relational calculus to bags.
