Schema.org注释的领域特定语义验证
Domain Specific Semantic Validation of Schema.org Annotations
摘要：
自2011年推出以来，schema.org已经成为在Web上发布语义描述的结构化数据的事实标准，通常以网页注释的形式。schema.org的日益普及促进了数据网络的增长，以及对这些数据进行操作的自动代理的开发。Schema.org是一个涵盖许多领域的大型异构词汇表。这显然不是一个bug，而是一个特性，因为schema.org旨在描述网络上的几乎所有内容，而网络是巨大的。然而，schema.org的异构性可能会导致副作用，这是为某个域中的注释选择正确的类和属性以及保持注释语义一致的挑战。在这项工作中，我们介绍了我们的基于规则的方法和它的实现，用于schema.org从两个方面验证www.example.com注释：（a）注释在指定领域方面的完整性，（b）基于预定义规则的值的语义一致性。我们展示了我们在旅游领域的方法。
英文摘要：
Since its unveiling in 2011, schema.org has become the de facto standard for publishing semantically described structured data on the web, typically in the form of web page annotations. The increasing adoption of schema.org facilitates the growth of the web of data, as well as the development of automated agents that operate on this data. Schema.org is a large heterogeneous vocabulary that covers many domains. This is obviously not a bug, but a feature, since schema.org aims to describe almost everything on the web, and the web is huge. However, the heterogeneity of schema.org may cause a side effect, which is the challenge of picking the right classes and properties for an annotation in a certain domain, as well as keeping the annotation semantically consistent. In this work, we introduce our rule based approach and an implementation of it for validating schema.org annotations from two aspects: (a) the completeness of the annotations in terms of a specified domain, (b) the semantic consistency of the values based on pre-defined rules. We demonstrate our approach in the tourism domain.
