Motivated by the need for OBDA systems supporting database-style aggregate queries, we propose a bag semantics for OBDA, where duplicate tuples in PDF | The conservativity theorem for nested relational calculus implies that query expressions can freely use nesting and unnesting, yet as long as the | Find, read and cite all the research Real-life databases however use bag, rather than set, semantics. For bags, instead of saying that a tuple is certainly in the answer, we have more detailed information: namely, the range of the numbers of occurrences of the tuple in query answers. 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 warded Datalog+-) 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 a practical 2019-09-27 · The TreeBag implementation works like any other tree, additionally maintaining Bag semantics..

(Section 4) We Learn about how word embeddings carry the semantic meaning of words, which makes them much more powerful for NLP tasks, then build your own 30 Dec 2016 A protocol's semantics are an integral part of its defintion.

The six collection classes are Set, SetHash, Bag, BagHash, Mix and MixHash. They all share similar semantics. In a nutshell, these classes hold, in general,

The operations of the relational algebra are extended to operate on bags by defining their action on tuple multiplicities. 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 impor-tant 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. In contrast, SQL queries have bag-theoretic semantics (i.e., in general duplicates are not eliminated).

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.

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.

Much of this is represented as semantic information or general knowledge. For example, Baddeley (1990) estimates that the typical adult knows the meaning of

While this result holds for queries over either set or multiset semantics, to the best of our knowledge, the questions of conservativity and normalization have not been studied for queries that mix set and bag collections, or provide duplicate-elimination operations such as SQL's $\mathtt{SELECT}~\mathtt{DISTINCT}$. Set versus bag semantics Set versus bag semantics Set No duplicates Relational model and algebra use set semantics Bag Duplicates allowed Number of duplicates is significant SQL uses bag semantics by default --- Set verses bag example --- A case for bag semantics Efficiency Saves time of eliminating duplicates Which one is more useful? π GPA In this work, we investigate the complexity of query containment problem for CQs under bag semantics (i.e.

Our first contribution is conceptual, namely, we give rigorous bag semantics to GLAV mappings and to the certain answers of conjunctive queries in the context of 9 Jul 2018 then relate this fragment to a Coq formalised (extended) relational algebra that enjoys a bag semantics.
