Specif- ically, the  SQL, the most important query language for relational databases, is actually a bag language. ◇Some operations, like projection, are more efficient on bags than  They will have to develop an approach to NLP that is both top-down and bottom- up: top- down to leverage symbolic models such as semantic networks and  However, the context guided learning strategy of word embeddings is likely to miss some semantics for text-level tasks. Text guided n- gram representation and   A bag is a random grouping of the objects in the list. A Collection is mapped with a element in the mapping table and initialized with java.util.ArrayList. 5 Aug 2020 Word embedding models like Word2Vec results in distributed representations that take semantics into account such that words with similar  Decidability and Complexity.

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). In this paper we study the optimization problems for conjunctive queries under bag-theoretic The distinction between set and bag semantics in databases is very significant in practice, and it influences the evaluation of aggregate queries. 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.

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. That  Set semantics versus bag semantics.
