Let's take a latent bag of words (BOW) model for paraphrase generation. We ground the semantics of a discrete latent variable by the BOW from the target sentences. We. NYU's Syntax Brown Bag is a series of informal talks on syntax and its interfaces with other subfields.

Subsequently, transform the similarity NLLP: bag-of-words semantics?

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 . Bag Semantics of DL-Lite with Functionality Axioms author: Egor V. Kostylev , Department of Computer Science, University of Oxford published: Dec. 10, 2019, recorded: October 2019, views: 3 Set Semantics vs. Bag Semantics Fact: • The algorithmic properties of conjunctive queries under set semantics are well understood.

tabases 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. We show that the behavior of positive queries is different under bag semantics: nding the minimum number of occur-

2019-09-01 · We conclude by observing that in the literature on query optimisation under bag semantics , , it is common to encounter the notion of bag-set semantics for databases, where input database instances are sets—that is, do not allow for multiplicities greater than 1—while permitting query answers and views to be bags. 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. 1 Introduction Ontology-based data access (OBDA) is an increasingly popu- In particular, SQL queries are evaluated under bag semantics and return multisets as answers, since duplicates are not eliminated unless explicitly requested. databases.

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.
