ITR: Science on the Semantic Web -- Prototypes in Bioinformatics

这一中型信息技术研究项目将开发一个框架，以促进语义网的科学研究和教育，并将实施和评估用于生物复杂性和生物多样性领域的原型工具和应用程序。这些能力包括通过Web文档的自动和半自动语义注释进行协作和传达含义的能力；使用背景知识和推理改进信息检索的能力；以及从多个不同来源提取和融合信息以响应查询的能力。国家生物信息基础设施(http://www.nbii.org/).)的门户网站将是这些能力的原型试验台该框架将包括用于创作、自动摄取和注释的本体、协议、代理和工具的规范。这些工具将利用协作构建的本体将不同的社区聚集在一起，并使科学知识的社区建设成为可能。将开发其他独立于领域的通用本体，以使有关数据库和其他知识储存库的内容和结构的元数据能够用RDF和OWL等新兴知识标记语言表达。这将使代理能够访问和索引隐藏的网络，还将支持对各种分布式数据库的数据挖掘。

This medium ITR project will develop a framework to facilitate scienceresearch and education on the semantic web, and will implement andevaluate prototype tools and applications for use in the biocomplexityand biodiversity domains. These capabilities include the ability tocollaborate and convey meaning through the automatic andsemi-automatic semantic annotation of web documents; to improveinformation retrieval using background knowledge and inference; and toextract and fuse information from multiple, heterogeneous sources inresponse to a query. A testbed for prototyping these capabilities willbe the web portal of the National Biological InformationInfrastructure (http://www.nbii.org/). The framework will includespecifications for ontologies, protocols, agents, and tools forauthoring, automated ingest, and annotation. These tools will leveragecollaboratively constructed ontologies to bring diverse communitiestogether and enable community construction of scientificknowledge. Additional domain-independent, general purpose ontologieswill be developed to enable metadata about the contents and structureof databases and other knowledge repositories to be expressed inemerging knowledge markup languages such as RDF and OWL. This willenable agents to both access and index the hidden web, and will alsosupport the data mining of diverse and distributed databases.
