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

EIA-0130422 Louiqa Raschid马里兰州大学园区CISE研究资源：开发多模型资源的大规模实验测试床的基础设施使用由因特网提供的以多种语言或模态表达的结构化和非结构化信息的广泛分布的集合，需要产生用于发现复制内容、确定源的延迟或访问等待时间、这个项目的目标是建立一个实验室测试平台，提供一个可控的环境，捕捉（可公开访问的）Web的结构、内容和延迟特性。这将促进研究人员之间的合作，他们的兴趣范围超过自然语言应用程序，语言独立的扫描文档处理，视频信息源的分析，信息检索，广域应用程序和跨异构服务器的资源发现。该试验台将支持以下方面的开发和测试：（1）用于跨语言和模态的相关信息的大规模、跨语言分析和发现的工具，（2）用于广域环境的成本模型和访问成本目录，反映访问等待时间的时间变化，（3）用于资源发现的媒体剪辑的基于分布式内容的索引和关联，（4）对多媒体资源进行代码转换和调度，以便在任何时间和任何地点向不同的客户端传送;从移动的无线到高速光链路。

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.
