This paper describes the VIRGIL (Virtual Meeting Archival) system which was developed to provide a simple, practical, easy-to-use method for recording, indexing and archiving large scale distributed videoconferences held over Access Grid nodes. Institutional libraries are coming under increasing pressure to support the storage, access and retrieval of such mixed-media complex digital objects in...

Formulating unambiguous queries in the Semantic Web applications is a challenging task for users. This article presents a new approach in guiding users to formulate clear requests based on their common nature of querying for information. The approach known as the front-end ap proach gives users an overview about the system data through a vir tual data component which stores the extracted metada...

This paper provides a snapshot of the state-of-the-art in information retrieval and information extraction from text through a selection of commercial, market-leading tools. Rooted in a research project conducted for the Belgian Police, we give an overview of the main (desired) features provided or lacked by these tools, along with their measured quality in operation. Various shortcomings and s...

Over time, memory retrieval is thought to transfer from the hippocampus to a distributed network of neocortical sites. Of these sites, the retrosplenial cortex (RSC) is robustly activated during retrieval of remotely acquired, emotionally valenced memories. It is unclear, however, whether RSC is specifically involved in memory storage or retrieval, and which neurotransmitter receptor mechanisms...

The amounts of information that mankind produces are vast, running into billions of documents. Traditional ways of holding this information have become impracticable and so methods of storage are being switched from paper and microfiche to magnetic and optical disks. In the last thirty years, as more information has been put onto computers, work has gone into using the computer to get away from...

The intention of this paper is to present HEAVEN, a solution of intelligent management of large-scale datasets held on tertiary storage systems. We introduce the common state of the art technique storage and retrieval of large spatiotemporal array data in the High Performance Computing (HPC) area. An identified major bottleneck today is fast and efficient access to and evaluation of high perfor...

Cleaning up and disposing of approximately 50 years of nuclear waste is the main mission at the U.S. Department of Energy’s Hanford Nuclear Reservation, located in the southeastern part of the state of Washington. A major element of the total cleanup effort involves retrieving, processing, and disposing of radioactive and hazardous waste stored in 177 underground storage tanks. referred to as t...

Software components have played an important role in modern software and system development. The main contribution of software components is reuse which helps reduce development cost and time and increase productivity. While libraries of Unified Modeling Language (UML) diagrams do exist, one of the challenges that still remain is to locate suitable diagrams and adapt them to meet the specific r...
