In this paper, we investigate issues involved in designing and using a cost model for query optimization in parallel database environments. The large range of possible multiprocessor computers, the different requirements of data-intensive applications to be supported, and the high number of parallel algorithms and information access methods make a(More)
In this big data era, huge amount data are continuously acquired for a variety of purposes. Advanced computing, imaging, and sensing technologies enable scientists to study natural and physical phenomena at unprecedented precision, resulting in an explosive growth of data. It is a huge challenge to visualize this growing data in static or in dynamic form.(More)
This paper presents a computational framework for information extraction and aggregation which aims to integrate and organize the data/information resources that spread throughout the Internet in the manner that makes them useful for tracking events such as natural disaster, and disease dispersion. We introduce a simple statistical information extraction(More)
The availability of huge volume of documents in digital form and the explosive growth of the Internet have necessitated intense interest in information retrieval techniques. Improving information searching beyond full text retrieval requires both appropriate document representation and document management. This research project develops a new infrastructure(More)
