From a practical 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-ca While this result holds for queries over either set or multiset semantics, to the best of our knowledge, the questions of conservativity and ormalization have not been studied for queries that mix set and bag collections, or provide duplicate-elimination operations such as SQL's SELECT DISTINCT. View Notes - Set versus bag semantics from ICS 424 at King Fahd University of Petroleum & Minerals. Set versus bag semantics Set versus bag semantics Set No duplicates Relational model and 2016-09-26 · SQL is the lingua franca for retrieving structured data. Existing semantics for SQL, however, either do not model crucial features of the language (e.g., relational algebra lacks bag semantics, correlated subqueries, and aggregation), or make it hard to formally reason about SQL query rewrites (e.g., the SQL standard's English is too informal).
To regain tractability, we consider a rather general class of queries and show its rewritability to a generalisation of the relational calculus to bags. READ FULL TEXT VIEW PDF A bag is a multi-set, a set that potentially contains multiple copies of the same tuple (depending on the schema). The following is a valid table: It just means that item 1 is bought twice. In set semantics, this would be identical to a relation storing only 3 tuples. • Bag semantics Dan Suciu -- 444 Spring 2010 7 .

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-. The semantic gap is the gap between the extracted and indexed low-level features by computers and the high-level concepts (or semantics) of user's queries.
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.

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.
