The Internet today has been transformed from a network providing connectivity, to a massive repository of human and machine knowledge, with information relevant to nearly every aspect of human life stored in some corner. Search engines allow keyword-based search of this knowledge, and while natural language queries are increasingly useful, searching for complex information often requires human thinking (augmented with the capabilities of search engines) to obtain useful search results. Routine problems require individuals to search the Internet for relevant ideas, a task which may be hindered by lack of expertise in the appropriate subject matters. With pervasive online connectivity, there are potentially unlimited ‘experts’ (or just helpers) available online to contribute their knowledge to problems related to their expertise. This project envisions tapping such potential experts (or helpers) to handle a large number of requests for information, leveraging the power of online collaboration. The relevance of this project should be increasingly apparent as the world moves towards a knowledge-based economy where the Internet is used for collaborative work, a significant part of which involves searching for information. The project will train students who will understand and extend the proposed approach. This project proposes a novel theoretical framework to analyze the dynamics of information searching. It includes information searching to handle multiple requests, collaboration of multiple experts from different fields, exploration of the concepts of expertise mismatch with the population of generated requests, and of diversity of expertise to allow faster searches for multi-disciplinary requests. While the issues to be studied bear similarity with multi-class queuing and scheduling, information searching uniquely uses information-theoretic ideas. These research activities require an interesting interplay between the fields of information theory, queuing theory, scheduling, and social network concepts.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

今天的互联网已经从提供连通性的网络转变为人类和机器知识的大量存储库，其中的信息几乎与存储在某个角落的人类生活的各个方面有关。搜索引擎允许基于关键字的搜索此知识，尽管自然语言查询越来越有用，但搜索复杂的信息通常需要人类思维（增强搜索引擎的功能）才能获得有用的搜索结果。常规问题要求个人搜索互联网上的相关想法，这项任务可能由于缺乏适当主题的专业知识而受到阻碍。有了普遍的在线连接，可能有无限的“专家”（或仅在线帮助者）为与其专业知识相关的问题做出贡献。该项目设想利用此类潜在的专家（或帮助者）来处理大量信息请求，利用在线协作的力量。随着世界向基于知识的经济发展，该项目的相关性应该变得越来越明显，在该经济中，互联网用于协作工作，其中很大一部分涉及搜索信息。该项目将培训将了解并扩展拟议方法的学生。该项目提出了一个新颖的理论框架，以分析信息搜索的动态。它包括用于处理多个请求的信息搜索，来自不同领域的多个专家的协作，对专业知识不匹配的概念与生成的请求人群不匹配的概念以及专业知识的多样性，以更快地搜索多学科请求。虽然要研究的问题与多级排队和日程安排相似，但信息搜索唯一使用信息理论思想。这些研究活动需要信息理论领域，排队理论，调度和社交网络概念之间的有趣相互作用。该奖项反映了NSF的法定使命，并使用基金会的知识分子优点和更广泛的影响来评估，被认为是珍贵的支持。
