CISE Research Resources: Infrastructure to Develop a Large Scale Experiment Testbed of Multi-modal Resources

EIA-0130422 Louiqa raschid马里兰大学学院公园cise研究资源：开发多模型资源的大规模实验测试平台的基础设施使用互联网提供的以多种语言或模式表示的广泛分布的结构化和非结构化信息集合，需要生产可扩展的、健壮的算法，用于发现复制内容、确定源的延迟或访问延迟，以及对抗互联网固有的动态性。这个项目的目标是建立一个实验室测试平台，提供一个受控的环境来捕获（可公开访问的）Web的结构、内容和延迟特征。这将促进研究人员之间的合作，他们的兴趣范围包括自然语言应用、扫描文档的语言独立处理、视频信息源分析、信息检索、广域应用和跨异构服务器的资源发现。该测试平台将支持以下项目的开发和测试：(1)用于大规模、跨语言分析和发现跨语言和模式的相关信息的工具；(2)用于广域环境的成本模型和访问成本目录，反映访问延迟的时间变化；(3)用于资源发现的基于分布式内容的媒体剪辑索引和关联；(4)用于随时随地向不同客户交付多媒体资源的转码和调度；从移动无线到高速光链路。

EIA-0130422 Louiqa RaschidUniversity of Maryland College ParkCISE Research Resources: Infrastructure to Develop a Large Scale Experiment Testbed of Multi-model ResourcesThe use of the widely distributed collections of structured and unstructured information expressed in multiple languages or modalities provided by the Internet, requires production of scalable, robust algorithms for the discovery of replicated content, determination of delay or access latency of sources, and the confrontation of the inherently dynamic nature of the Internet.This project's objective is to establish a laboratory testbed providing a controlled environment that captures structural, content, and latency characteristics of the (publicly accessible) Web. This will stimulate collaboration between researchers whose interests range over natural language applications, language independent processing of scanned documents, analysis of video information sources, information retrieval, and wide area applications and resource discovery across heterogeneous servers. The testbed will support the development and testing of: (1) tools for broad-scale, cross-linguistic analysis and discovery of relevant information across languages and modalities, (2) cost models and access cost catalogs for wide area environments, reflecting the temporal variability in access latency, (3) distributed content based indexing and association of media clips for resource discovery, (4) transcoding and scheduling of multimedia resources for delivery any time and anywhere to disparate clients; from mobile wireless to high speed optical links.
