This project creates an open platform for accessing and mining information from scientific texts that provides access to an array of software, computing resources, and publication data. Current search technologies typically find many relevant documents, but do not extract and organize the information content of these documents or suggest new scientific hypotheses based on this organized content. Natural Language Processing (NLP) strategies are a recognized means to approach this problem, and this project develops the cyberinfrastructure to support sophisticated search and retrieval from scientific publications, use and augmentation of facilities for advanced and well-established natural language processing and machine learning tools, and extraction and aggregation of data from scientific publications. The project leverages two NSF-funded projects: the Language Applications (LAPPS) Grid, which has already proven to be an effective platform for development of NLP applications; and University of Wisconsin’s xDD (formerly, GeoDeepDive), a scalable, dependable infrastructure capable of rapidly growing a digital library of scientific publications, currently including over 13 million documents from multiple distributed commercial and open-access providers. The effort significantly enhances the value of these existing NSF-funded infrastructures by providing access to services for mining scientific publications and lowering the barriers to entry resulting from licensing, redistribution, and intellectual property issues. Scientists may perform large-scale text retrieval and mining using the University of Wisconsin’s high performance computing (HPC) infrastructure through a web-based interface. Iterative domain adaptation capabilities allow scientists to easily adapt existing services to specialized areas without configuring or installing additional components. The potential impact of the cyberinfrastructure is applicable to any community that relies on computational tools for mining large textual datasets, including researchers in sociology, psychology, economics, education, linguistics, digital media, and the humanities.This project extends the LAPPS Grid to provide access to UW-xDD’s collection of scientific publications and UW’s High Performance Computing facilities, as well as means to rapidly adapt existing, well-established natural language processing and machine learning software tools to new domains and evaluate results. The LAPPs Grid provides a large collection of NLP tools from a wide variety of sources exposed as web services, together with multiple commonly used resources and a front-end document retrieval engine currently configured to access PubMed/PubMedCentral as well as nightly updates of the CORD-19 dataset. The LAPPS Grid is open source, and can be run from the web, on a user’s laptop or desktop, in the cloud, or as a self-contained docker image when it is necessary to protect sensitive or licensed data, when there is no network connection available, or for deployment on remote HPC facilities. All tools and resources can be used interoperably, eliminating the effort required to convert input and output formats to use a set of tools or resources together. xDD is one of the world’s largest single repositories of scientific publications that spans all domains of knowledge, incorporates new documents automatically and updates API endpoints every hour. xDD has accumulated millions of documents from multiple commercial and open-access publishers (over 13M publications). The xDD infrastructure is an integral part of the developing UW-COSMOS pipeline, which consists of a suite of services supporting document processing, including ingestion and parsing of PDFs; extraction of individual document objects such as text sections, figures, tables, and captions; and recall, which creates searchable Anserini and ElasticSearch indexes on the contexts and objects to enable retrieval of information. Specific project activities include implementing efficient retrieval and analysis of xDD’s vast holdings of scientific publications; extending the NLP capabilities of the LAPPS Grid for scientific publication mining and domain adaptation; developing full interoperability between the Grid and xDD/COSMOS; scaling LAPPS Grid services to handle the very large textual datasets available from UW-xDD; and surveying visualization techniques and integrating them into the Grid.This award by the Office of Advanced Cyberinfrastructure is jointly supported by the NSF Division of Information and Intelligent Systems within the Directorate for Computer and Information Science and Engineering, and the NSF Public Access program.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.

该项目创建了一个开放平台，用于访问和挖掘科学文本中的信息，提供对一系列软件，计算资源和出版数据的访问。 当前的搜索技术通常找到许多相关文档，但不提取和组织这些文档的信息内容或基于该组织的内容提出新的科学假设。自然语言处理（NLP）战略是解决这一问题的公认手段，该项目开发了网络基础设施，以支持科学出版物的复杂搜索和检索，使用和增强先进和完善的自然语言处理和机器学习工具的设施，以及从科学出版物中提取和汇总数据。该项目利用了两个NSF资助的项目：语言应用（LAPPS）网格，它已经被证明是开发NLP应用程序的有效平台;以及威斯康星州大学的xDD（以前称为GeoDeepDive），这是一个可扩展的、可靠的基础设施，能够快速发展科学出版物的数字图书馆，目前包括来自多个分布式商业和开放访问提供商的1300多万份文档。通过为采矿科学出版物提供服务，降低许可证、再分配和知识产权问题造成的进入壁垒，这一努力显著提高了这些现有NSF资助基础设施的价值。科学家们可以通过基于网络的界面，使用威斯康星州大学的高性能计算（HPC）基础设施进行大规模的文本检索和挖掘。迭代域适应功能使科学家能够轻松地将现有服务适应特定领域，而无需配置或安装额外的组件。网络基础设施的潜在影响适用于任何依赖计算工具挖掘大型文本数据集的社区，包括社会学，心理学，经济学，教育学，语言学，数字媒体和人文科学的研究人员。该项目扩展了LAPPS网格，以提供对UW-xDD科学出版物和UW高性能计算设施的访问，以及使现有的、完善的自然语言处理和机器学习软件工具快速适应新领域并评估结果的手段。LAPPs Grid提供了大量的NLP工具，这些工具来自各种各样的Web服务，以及多个常用的资源和一个前端文档检索引擎，当前配置为访问PubMed/PubMedCentral以及CORD-19数据集的夜间更新。LAPPS网格是开源的，可以从Web、用户的笔记本电脑或台式机、云中运行，或者在需要保护敏感或许可数据时作为自包含的Docker映像运行，当没有可用的网络连接时，或者用于部署在远程HPC设施上。所有工具和资源都可以互操作地使用，从而消除了将输入和输出格式转换为一起使用一组工具或资源所需的工作。 xDD是世界上最大的科学出版物单一存储库之一，涵盖所有知识领域，自动合并新文档并每小时更新API端点。 xDD已经积累了来自多个商业和开放获取出版商的数百万文档（超过1300万出版物）。 xDD基础设施是开发中的UW-COSMOS管道的一个组成部分，它由一套支持文档处理的服务组成，包括PDF的摄取和解析;提取单个文档对象，如文本部分，图形，表格和标题;以及召回，它在上下文和对象上创建可搜索的Anserini和ElasticSearch索引，以实现信息检索。具体的项目活动包括对xDD的大量科学出版物进行有效的检索和分析;扩展LAPPS网格的自然语言处理能力，用于科学出版物挖掘和领域调整;开发网格与xDD/COSMOS之间的全面互操作性;扩展LAPPS网格服务，以处理UW-xDD提供的非常大的文本数据集;以及调查可视化技术并将其集成到网格中。高级网络基础设施办公室的这一奖项得到了计算机和信息科学与工程理事会内的NSF信息和智能系统部门的共同支持，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
