CSR---PDOS: Information Pedigree

随着可用信息范围的扩大，在需要的时候找到需要的信息变得越来越困难。搜索行业的发展证明了这一问题，但现有的工具是不完整的解决方案。它们索引内容，而不是上下文。它们只捕获静态的句法关系，而不是动态的语义锥。也许最重要的是，他们只能访问存储在用户本地计算机或公共可访问的分布式存储上的信息-其他来源既不索引也不能搜索。信息谱系通过捕获信息项之间的上下文和语义关系、收集不同关系的元数据来支持搜索并提供在由个人用户控制的机器上创建的相关项的可用性来解决这个问题。信息谱系通过规范用户的应用程序和服务之间的信息流以及不同用户之间的信息流来实现这一目标。通过观察这些交易，我们对使用的数据形成了上下文和语义索引，简化了检索以供以后使用。信息谱系将使人们更容易查找和共享数据，而不会给他们或他们的IT支持人员带来额外的负担。这极大地减少了管理信息所浪费的时间，使信息工作者的工作效率更高。该项目的结果将在研究文献中广泛传播，并将向其他研究人员和用户提供该系统的原型。该项目将培养几名研究生，并影响几个研究生和本科课程的课程。

As the scope of available information grows, it is increasinglydifficult to find what one needs when it is needed. The growth ofsearch as an industry is testament to this problem, but existing toolsare incomplete solutions. They index content, but not context. Theycapture only static, syntactic relationships, not dynamic, semanticones. Perhaps most importantly, they have access only to informationstored either on a user's local machine or publicly-accessibledistributed stores---other sources are neither indexed nor searchable.Information Pedigree solves this problem by capturing context andsemantic relationships between information items, collecting disparaterelationship meta-data to support searches, and providing foravailability of relevant items created on machines controlled byindividual users. Information Pedigree achieves this goal byinstrumenting the flow of information between a user's applicationsand services, as well as the flow of information between differentusers. By observing these transactions, we form a contextual andsemantic index over data that is used, simplifying its retrieval forlater use.Information Pedigree will make it easier for people to find and sharedata, without placing additional burdens on them or their IT supportstaff. This greatly reduces time wasted in managing information,allowing information workers to be more productive. The results fromthis project will be widely disseminated in the research literature,and a prototype of the system will be made available to otherresearchers as well as users. This project will train severalgraduate students, and influence the curricula of several graduate andundergraduate courses.
