| 中文简介: |
目前，Web上有相当数量的数据是通过Web API提供的，这些API以JSON或XML等格式公开数据。组合来自不同API和数据源的数据需要胶代码，胶代码通常不共享，因此不可重用。我们提出了链接数据服务（LIDS），这是一种将数据提供服务与链接数据集成的通用形式化方法，是一种流行的数据发布机制，它促进了数据集成并允许分散发布。我们为符合链接数据原则的服务访问接口提供约定，并提供抽象的轻量级服务描述形式。我们开发了使用LIDS描述在服务和现有数据集之间自动创建链接的算法。为了评估我们的方法，我们实现了对现有服务的LIDS包装器和LIDS描述，并测量了数十亿次三次自动链接算法的性能和有效性。

| 课程简介: |
A sizable amount of data on the Web is currently available via Web APIs that expose data in formats such as JSON or XML. Combining data from different APIs and data sources requires glue code which is typically not shared and hence not reused. We propose Linked Data Services (LIDS), a general, formalised approach for integrating data-providing services with Linked Data, a popular mechanism for data publishing which facilitates data integration and allows for decentralised publishing. We present conventions for service access interfaces that conform to Linked Data principles, and an abstract lightweight service description formalism. We develop algorithms that use LIDS descriptions to automatically create links between services and existing data sets. To evaluate our approach, we realise LIDS wrappers and LIDS descriptions for existing services and measure performance and effectiveness of an automatic interlinking algorithm over multiple billions of triples.
