Most retrieval algorithms do not differentiate the structure of tweets. The authors show convincingly that it does have an impact on retrieval effectiveness. In their stu...... Mar 28 2014     Principles of database query processing for advanced applications Yu C., Meng W., Morgan Kaufmann Publishers Inc., San Francisco, CA, 1998.  Type: Book (9781558604346) A wide variety of query processing approaches for numerous application domains, such as text retrieval, are surveyed. The book is organized and developed well. Each chapter is self-contained and dedicated to a specific area, such as te...... Jul 1 1998     Principles of database query processing for advanced applications Yu C., Meng W., Morgan Kaufmann Publishers Inc., San Francisco, CA, 1998.  Type: Book (9781558604346) Any information system based on a network of computers has complex design and implementation issues. Performance issues may have to be dealt with by trial and error, because of the lack of tools and techniques to model and predict perf...... May 1 1998     Necessary and sufficient conditions to linearize doubly recursive programs in logic databases Zhang W., Yu C., Troy D. ACM Transactions on Database Systems 15(3): 459-482, 1990.  Type: Article In the simplest case, a doubly recursive program to a deductive database contains an exit rule and a recursive rule in which the exit rule appears exactly twice. This paper investigates conditions under which such a program can be tran...... Nov 1 1992     Query processing in a fragmented relational distributed system: Mermaid Yu C., Chang C., Templeton M., Brill D., Lund E. IEEE Transactions on Software Engineering SE-11(9): 795-810, 1985.  Type: Article This paper describes the implementation of a query optimization algorithm in a distributed system of heterogeneous databases. The optimizer exists as a front-end process at each distributed site. The sharing of operations and data on t...... Apr 1 1986     Display 510152550100 per column
