Multiple-Query Optimization
- ACM Transactions on Database Systems
, 1988
"... Some recently proposed extensions to relational database systems, as well as to deductive database systems, require support for multiple-query processing. For example, in a database system enhanced with inference capabilities, a simple query involving a rule with multiple definitions may expand to m ..."

Interactive Visualization of Multiple Query Results
- Proc. IEEE Information Visualization Symp
, 2001
"... This paper introduces a graphical method for visually presenting and exploring the results of multiple queries simultaneously. This method allows a user to visually compare multiple query result sets, explore various combinations among the query result sets, and identify the “best ” matches for comb ..."

The Lorel Query Language for Semistructured Data
- International Journal on Digital Libraries
, 1997
"... We present the Lorel language, designed for querying semistructured data. Semistructured data is becoming more and more prevalent, e.g., in structured documents such as HTML and when performing simple integration of data from multiple sources. Traditional data models and query languages are inapprop ..."

Combining the Evidence of Multiple Query Representations for Information Retrieval
- Information Processing & Management
, 1995
"... Abstract-We report on two studies in the TREC-2 program that investigated the effect on retrieval performance of combination of multiple representations of TREC topics. In one of the projects, five separate Boolean queries for each of the 50 TREC routing topics and 25 of the TREC ad hoc topics were ..."

On Multiple Query Optimization in Data Mining
- Proceedings of the 9th Pacic-Asia Conference on Knowledge Discovery and Data Mining
, 2005
"... Abstract. Traditional multiple query optimization methods focus on identifying common subexpressions in sets of relational queries and on constructing their global execution plans. In this paper we consider the problem of optimizing sets of data mining queries submitted to a Knowledge Discovery Man ..."

Optimizing Query Rewriting for Multiple Queries
"... We present an scalable algorithm for answering multiple conjunctive queries using views. This is an important problem in query optimization, data integration and ontology-based data access. Since rewriting one conjunctive query using views is an NP-hard problem, we develop an approach where answerin ..."

Multiple Query Optimization in Mediator Systems
"... With the increase in mediated applications, there are now mediated application servers that support concurrent client accesses. Multiple query optimization (MQO) is essential for efficient processing of concurrent read only queries. The MQO problem in mediated environments differs from that of ordin ..."

Common Subexpression Isolation in Multiple Query Optimization
- Query Processing in Database Systems
, 1985
"... Abstract: The simultaneous optimization of multiple queries submitted to a database system may lead to substantial savings over the current approach of optimizing each query separately. Isolating common subexpressions in multiple queries and treating their execution as a sharable resource are import ..."
