A Multi-Query Optimizer for Monet [chapter]

Stefan Manegold, Arjan Pellenkoft, Martin Kersten
2000 Lecture Notes in Computer Science  
Experimental results on a single CPU system and a parallel system show that the inter-application multi-query optimizer improves the query evaluation performance significantly.  ...  Each application generates an "optimal" plan-a sequence of low-level database operators-for accessing the database.  ...  We would like to thank Florian Waas for his contributions to a prototype of the multi-query optimizer.  ...

Memory Aware Query Routing in Interactive Web-Based Information Systems [chapter]

Florian Waas, Martin L. Kersten
2001 Lecture Notes in Computer Science  
Query throughput is one of the primary optimization goals in interactive web-based information systems in order to achieve the performance necessary to serve large user communities.  ...  However, the actual key to enhanced throughput is a resource efficient scheduling of the arriving queries.  ...  Powerful, user interfaces for multi-media object retrieval concurrently submit large numbers of queries to the database back-end which make throughput optimization a primary optimization goal.  ...

Accelerating XPath evaluation in any RDBMS

Torsten Grust, Maurice Van Keulen, Jens Teubner
2004 ACM Transactions on Database Systems  
This article is a proposal for a database index structure, the XPath accelerator, that has been specifically designed to support the evaluation of XPath path expressions.  ...  : the index (a) permits set-oriented (or, rather, sequence-oriented) path evaluation, and (b) can be implemented and queried using well-established relational index structures, notably B-trees and R-trees  ...  ACKNOWLEDGMENTS The authors would like to thank the Monet people at CWI (Amsterdam, The Netherlands) for their support and most useful feedback. The comments of  ...

Exploratory search on topics through different perspectives with DBpedia

Nicolas Marie, Fabien Gandon, Alain Giboin, Émilie Palagi
2014 Proceedings of the 10th International Conference on Semantic Systems - SEM '14  
A promising scenario for combining linked data and search is exploratory search. During exploratory search, the search objective is ill-defined favorable to discovery.  ...  A common limit of the existing linked data based exploratory search systems is that they constrain the exploration through single results selection and ranking schemes.  ...  source of knowledge for such multi-perspectives exploratory search.  ...

Experiences with IR TOP N Optimization in a Main Memory DBMS: Applying 'the Database Approach' in New Domains [chapter]

Henk Ernst Blok, Arjen P. de Vries, Henk M. Blanken, Peter M. G. Apers
2001 Lecture Notes in Computer Science  
Top-N queries form a natural query class when dealing with content retrieval. In the IR field, a lot of research has been done on processing top-N queries efficiently.  ...  Unfortunately, these results cannot directly be ported to the database environment, because their tuple-oriented nature would seriously limit the freedom of the query optimizer to select appropriate query  ...  Also, such state of the art search engines make use of (query) caching techniques closely related to database optimization techniques like multi query optimization, which we haven't incorporated in our  ...
