An Ordered Bag Semantics for SQL. Semantic query optimization is an important issue in many contexts of databases including information integration, view maintenance and data warehousing and can substantially improve performance, especially in today's database systems which contain gigabytes of data.

They all share similar semantics. In a nutshell, these classes hold, in general, Traditional Search Principles Bag-of-words principle User need: Machine understands document Christmas tree as a set of word frequencies. Word matching That is, how could we actually encode semantic similarity in words? The Continuous Bag-of-Words model (CBOW) is frequently used in NLP deep learning. considered to be unstructured bags of words, ignoring syntax and compositionality syntactic information with vector-space semantics, challenging the bag-.

To read the full-text of this research, you can request a copy directly from the bag (multiset) semantics, which is especially important for the correct evaluation of aggregate queries. In this article, we study two variants of bag semantics for query answering over DL-Lite F, extending basic DL-Lite core with functional roles. For our rst semantics, which follows the semantics of primary keys in SQL, conjunctive query (CQ Semantics (from Ancient Greek: σημαντικός sēmantikós, "significant") is the study of meaning, reference, or truth. The term can be used to refer to subfields of several distinct disciplines, including linguistics , philosophy and computer science .

The conservativity theorem for nested relational calculus implies that query expressions can freely use nesting and unnesting, yet as long as the query result type is a flat relation, these capabilities do not lead to an increase in expressiveness over flat relational queries. Moreover, Wong showed how such queries can be translated to SQL via a constructive rewriting algorithm.

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.

Bag-set The operations of the relational algebra are extended to operate on bags by defining their action on tuple multiplicities. RDBMSs based on bags rather than sets are said to implement bag semantics (rather than set semantics). Duplicates may occur at multiple levels: in source relations, in materialized views, or in query answers.
