Using Linear Algebra for Intelligent Information Retrieval
- SIAM REVIEW
, 1995
"... Currently, most approaches to retrieving textual materials from scientific databases depend on a lexical match between words in users' requests and those in or assigned to documents in a database. Because of the tremendous diversity in the words people use to describe the same document, lexical ..."

Data-centric Multi-level Blocking
, 1997
"... We present a simple and novel framework for generating blocked codes for high-performance machines with a memory hierarchy. Unlike traditional compiler techniques like tiling, which are based on reasoning about the control flow of programs, our techniques are based on reasoning directly about the fl ..."

the flow of data through the memory hierarchy. Our data-centric transformations permit a more direct solution to the problem of enhancing data locality than current control-centric techniques do, and generalize easily to multiple levels of memory hierarchy. We buttress these claims with performance numbers
A Framework for Collecting Provenance in Data-Centric Scientific Workflows
- In ICWS
, 2006
"... The increasing ability for the earth sciences to sense the world around us is resulting in a growing need for datadriven applications that are under the control of data-centric workflows composed of grid- and web- services. The focus of our work is on provenance collection for these workflows, neces ..."

The Impact of Workflow Tools on Data-centric Research
- SCIENTIFIC INFRASTRUCTURE
"... ... in which hypotheses are not only tested through directed data collection and analysis but also generated by combining and mining the pool of data already available [1-3]. The scientific data landscape we draw upon is expanding rapidly in both scale and diversity. Taking the life sciences as an e ..."

Decentralized Orchestration of Data-centric Workflows in Cloud Environments
"... Data-centric and service-oriented workflows are commonly used in scientific research to enable the composition and execution of complex analysis on distributed resources. Although there are a plethora of orchestration frame-works to implement workflows, most of them are unsuitable for executing (en- ..."

A Data-Centric Perspective for Workflow Model Management
- International Conference on Information Systems (ICIS 2011
, 2011
"... With increasingly widespread adoption of workflow technology as a standard solution to business process management, much effort is put on designing appropriate workflow models. The reuse of existing models has been recently suggested to support more efficient workflow design, which requires the stor ..."

the storage, search and composition of workflow models. In this paper, we propose a new framework of workflow model management from a data-centric perspective, which provides unique features lacking in existing approaches based on control flow and function description. We develop a data-centric indexing
Merging Application-centric and Data-centric Approaches to Support Transaction-oriented Multi-system Workflows
, 1993
"... Workflow management is primarily concerned with dependencies between the tasks of a workflow, to ensure correct control flow and data flow. Transaction management, on the other hand, is concerned with preserving data dependencies by preventing execution of conflicting operations from multiple, concu ..."

An Algebraic Approach for

In many situations, these workflows are computationally and data intensive, thus requiring execution in large-scale parallel computers. However, parallelizatio ..."

of scientific workflows. We conducted a thorough validation of our approach using both a real oil exploitation application and synthetic data scenarios. The experiments were run in Chiron, a data-centric scientific workflow engine implemented to support our algebraic approach. Our experiments demonstrate
