中文简介:
对Web上可用的非文本媒体的语义描述可以促进媒体资产的检索、重用和表示。语义Web语言可以表示Web上媒体内容的受控词汇表和共享注释。通过识别要考虑的概念，统一资源标识符(uri)是语义Web的构建块。通常，图像的特定区域或视频的特定序列需要本地化和唯一标识，以便在RDF注释中用作主题或对象资源。在这次演讲中，我们将首先介绍媒体片段URI规范，这是最近的W3C推荐标准，可以惟一地标识媒体资产的子部分，就像URI中的片段标识符可以引用HTML或XML文档的一部分一样。然后，我们将描述模型和本体，我们将使用附加到媒体片段的语义注释来说明几个真实世界的应用程序。
课程简介: Semantic descriptions of non-textual media available on the Web can facilitate retrieval, re-use and presentation of media assets. Semantic Web languages can represent controlled vocabularies and shared annotations of media content on the Web. By identifying concepts to consider, Uniform Resource Identifiers (URIs) are the building blocks of the Semantic Web. Often, particular regions of an image or particular sequences of a video need to be localized and uniquely identified in order to be used as subject or object resource in an RDF annotation. In this talk, we will first present the Media Fragment URI specification, a recent W3C recommendation that enables to uniquely identifying sub-parts of media assets in the same way that the fragment identifier in the URI can refer to part of an HTML or XML document. We will then describe models and ontologies that we will illustrate with several real world applications using semantic annotations attached to media fragments.
