Scientific Table Search Using Keyword Queries
Tables are common and important in scientific documents, yet most text-based document search systems do not capture structures and semantics specific to tables. How to bridge different types of mismatch between keywords queries and scientific tables and what influences ranking quality needs to be carefully investigated. This paper considers the structure of tables and gives different emphasis t...
متن کاملSemantic Web Queries over Scientific Data
The amount of scientific and engineering data has grown exponentially in the recent decades [29], and this growth includes the rapid increase in the amount of data sources publicly available on the web [16]. Complexity and diversity (structural, terminological, etc.) of this data is also expected to rise steadily in the coming decades, as novel data models emerge along with new and unforeseen a...
متن کاملCustomizable Parallel Execution of Scientific Stream Queries
Scientific applications require processing highvolume on-line streams of numerical data from instruments and simulations. We present an extensible stream database system that allows scalable and flexible continuous queries on such streams. Application dependent streams and query functions are defined through an object-relational model. Distributed execution plans for continuous queries are desc...
متن کاملUsing Domain-Specific Data to Enhance Scientific Workflow Steering Queries
In scientific workflows, provenance data helps scientists in understanding, evaluating and reproducing their results. Provenance data generated at runtime can also support workflow steering mechanisms. Steering facilities for workflows is considered a challenge due to its dynamic demands during execution. To steer, for example, scientists should be able to suspend (or stop) a workflow execution...
متن کاملEnabling Ad Hoc Queries over Low-Level Scientific Data Sets
Technological success has ushered in massive amounts of data for scientific analysis. To enable effective utilization of these data sets for all classes of users, supporting intuitive data access and manipulation interfaces is crucial. This paper describes an autonomous scientific workflow system that enables high-level, natural language based, queries over low-level data sets. Our technique in...
