Collaborative Project: Managing Authority Lists for Customized Linking and Visualization

这是一个与塔夫茨大学合作的项目（奖励号0226304）。该项目正在开发可定制的权威链接环境（SCALE）服务，以支持国家STEM教育数字图书馆（NSDL）中的所有级别的阅读。 特别是，该项目正在开发两大类服务。 首先，调查人员正在提供自动链接服务，自动将关键词和短语与补充信息绑定。 这些服务帮助学生、特定学科以外的专业人员和感兴趣的公众阅读充满不熟悉的技术术语和概念的文件。 例如，天文学学生和好奇的业余爱好者可能需要看到缩略词的扩展-例如，柯伊伯带天体的图片;或者正在努力撰写生物发光研究论文的学生可能需要找到有关特定化学过程或棘皮动物相关物种的信息。 第二，研究人员正在将自动链接建立在对名称和术语的权威控制以及不同权威列表（如主题词表、词汇表、百科全书、主题层次结构和对象目录）之间的链接的基础上。该项目的活动包括：* 创建和维护从开放档案倡议（OAI）元数据中获取的技术术语和概念的权威列表，从全文中提取，并从现有的权威列表中导入;* 扩展现有的自动超文本功能，在NSDL中的HTML、PDF和XML文件中嵌入技术术语注释和相关段落的链接;* 通过基于简单对象访问协议（SOAP）的Web服务提供术语检测和文件链接;* 与国家虚拟天文台合作评估SCALE的接口和功能;* 通过明确的用户配置和自适应学习偏好来定制SCALE;以及 * 收集关于链接质量的注释，以提高精度并为未来的系统提供培训集。（http：//www.perseus.tufts.edu/）和约翰霍普金斯数字知识中心（网址：//dkc.mse.jhu.edu/）已经专注于利用各种权威列表（地名词典、传记词典、词典、专业术语汇编、和名称权威文件），用于自动生成超文本链接和用于可视化，例如自动生成的动态地图和时间线。 这种链接生成补充了目前自动识别和汇总引文的做法。 目前的项目扩大和转让现有的管理权威名单的技术，将其从研究工作转变为服务于更广泛社区的制度化服务。

This is a collaborative project with Tufts University (Award No. 0226304).This project is developing Services for a Customizable Authority Linking Environment (SCALE) to support all levels of reading in the National STEM Education Digital Library (NSDL). In particular, the project is developing two broad classes of service. First, the investigators are providing automatic linking services that automatically bind key words and phrases to supplementary information. Such services help students, professionals outside a particular discipline, and the interested public to read documents full of unfamiliar technical terms and concepts. For example, astronomy students and curious amateurs may need to see expansions of acronyms--e.g., MACHO (massive compact halo object)--or pictures of "Kuiper belt objects"; or the student struggling with research papers on bioluminescence may need to locate information about particular chemical processes or relevant species of echinoderms. Second, the investigators are basing automatic linking on authority control of names and terms and on links among different authority lists such as thesauri, glossaries, encyclopedias, subject hierarchies, and object catalogues.Activities in the project include:* creating and maintaining authority lists of technical terms and concepts harvested from Open Archives Initiative (OAI) metadata, extracted from full text, and imported from existing authority lists;* extending current automatic hypertext capabilities to embed glosses of technical terms and links to related passages within HTML, PDF, and XML documents in the NSDL;* providing term detection and document linking through Simple Object Access Protocol (SOAP)-based Web services;* evaluating the interface to and functionality of SCALE in cooperation with the National Virtual Observatory;* customizing SCALE through explicit user configuration and adaptive learning of preferences; and* collecting annotations on the quality of links to improve precision and provide a training set for future systems.Much of the work at the Tufts University Perseus Digital Library Project (http://www.perseus.tufts.edu/) and the Johns Hopkins Digital Knowledge Center (http://dkc.mse.jhu.edu/) has already focused on exploiting various kinds of authority lists (gazetteers, biographical dictionaries, dictionaries, glossaries of technical terms, and name authority files) for the automatic generation of hypertext links and for visualizations such as automatically generated dynamic maps and timelines. Such link generation complements the current practice of automatic identification and aggregation of citations. The current project augments and transfers the existing technology for managing authority lists, converting this from a research effort to an institutionalized service serving a wider community.
