Indexing Multidimensional Objects in a Large Semantic Cache
by Beomseok Nam, Henrique Andrade, Alan Sussman
…bsnam,als¤ Semantic caches allow queries that require processing large scientific datasets to take advantage of cached objects, either directly or through automatic data transformations. During query planning, semantic information associated with each cached object is employed to locate all the obje…

Towards a Knowledge Base Management System (KBMS): An Ontology-Aware Database Management System (DBMS)
by Henrique C. M. Andrade, Joel Saltz — 1999 — In Proceedings of the 1999 Brazilian Symposium on Databases. SBC
…This paper aims to provide limited knowledge awareness to a conventional DBMS (Database Management Systems). This goal is achieved by extending an off-the-shelf DBMS (Postgresql in our case) in such way that it becomes ontology aware. The concept of ontology is used in our approach as a way of forma…

Decision Tree Construction for Data Mining on Cluster of Shared-Memory Multiprocessors
by Henrique Andrade, Tahsin Kurc, Alan Sussman, Joel Saltz
…Classification of very large datasets is a challenging problem in data mining. It is desirable to have decision-tree classifiers that can handle large datasets, because a large dataset often increases the accuracy of the resulting classification model. Classification tree algorithms can benefit from…

Exploiting Functional Decomposition for Efficient Parallel Processing of Multiple Data Analysis Queries
by Henrique Andrade, Tahsin Kurc, Alan Sussman, Joel Saltz — 2002
…Reuse is a powerful method for improving system performance. In this paper, we examine functional decomposition for improving data reuse, and therefore overall query execution performance, in the context of data analysis applications. Additionally, we look at the performance effects of using various…

Servicing Mixed Data Intensive Query Workloads
by Henrique Andrade, Tahsin Kurc, Alan Sussman, Eugene Borovikov, Joel Saltz — 2002
…When data analysis applications are employed in a multiclient environment, a data server must service multiple simultaneous queries, each of which may employ complex user-defined data structures and operations on the data. It is then necessary to harness inter- and intra-query commonalities and syst…
