U.S.-New Zealand and Australia Collaboration on Research for Data Compression

0301896Adjeroh该奖项支持西弗吉尼亚大学的Donald Adjeroh教授访问新西兰，在那里他将与坎特伯雷大学的Tim Bell教授合作，并访问澳大利亚，在那里他将与墨尔本大学的Alistair Moffat教授合作。另一项配套提案（INT-0331188）支持他的美国同事、中佛罗里达大学的Amar Mukherjee实现同样的目标。这些访问旨在启动计算机科学领域的教师交流访问和研究生指导计划。他们的核心研究最近得到了美国国家科学基金会（NSF）资助项目IIS-0312484的资助，“超大文本和图像存储库的压缩搜索和检索”。最近，普通计算机用户通常可以获得的多媒体数据量激增，这使得找到管理大量数据的新方法变得至关重要。这些研究者正在开发更有效地组织、存储、搜索和检索数据的新方法。他们的工作涉及一种新的数据压缩方法，这种方法使用“排序上下文”，允许在仍然被压缩的数据文件中搜索特定信息。他们正在开发新的压缩方案和新的搜索方法来处理这些压缩数据。这项研究将在科学和工程研究以及社会需求方面有重要的应用，例如电子图书馆、互联网搜索引擎、国土安全、经济、环境和医疗数据库以及许多其他形式的文本和图像存储库。此外，几名研究生参与了该项目，并将受益于接触美国以外最先进的研究

0301896AdjerohThis award supports Professor Donald Adjeroh of West Virginia University for a visit to New Zealand, where he will work with Professor Tim Bell of the University of Canterbury, and to Australia, where he will work with Professor Alistair Moffat of the University of Melbourne. A companion proposal (INT-0331188) supports his U.S. colleague Amar Mukherjee of the University of Central Florida for the same objectives. These visits are intended to initiate a program of faculty exchange visits and graduate student mentoring in the Computer Sciences. Their core research was recently funded by NSF grant IIS-0312484, "Compressed Search and Retrieval for Very Large Text and Image Repositories."The recent explosion in the amount of multimedia data typically available to an ordinary computer user has made it crucial to find new ways to manage massive amounts of data. These investigators are developing new methods for organizing, storing, searching and retrieving data more efficiently. Their work involves a new approach to data compression that uses "sorted contexts", which permits searching for specific information within data files that are still compressed. They are developing both new compression schemes and new search methodologies for working with such compressed data. This research will have significant applications in both science and engineering research and in societal needs such as electronic libraries, internet search engines, homeland security, economic, environmental and medical data bases and many other forms of text and image repositories. In addition, several graduate students are involved in the project and will benefit from exposure to state-of-the-art research being done outside of the U.S.
