Abstract

This work presents an architecture that supports collaborative semantic annotation for audiovisual (AV) contents on the web. The main goal is to propose a semantically oriented infrastructure to organize audiovisual material produced by Brazilian points of culture and independent producers so as to optimize the searches made by community TV broadcasters, schools, film societies and internauts. The collaboration will rely on a content annotation scheme, designed to stimulate both consumers and producers to enrich the overall content description by incorporating viewpoints and meanings associated to relevant scenes, regions and objects present in the production. The proposed architecture is based on technologies for AV content description, such as MPEG-7, semantic web concepts and the Ontology Web Language (OWL). This work considers that collaborative approaches, along with the on-going efforts in expanding the coverage of Internet broadband access in Brazil, will foster the dissemination of the digital technologies in the production and recording of cultural manifestations, allowing artists and entities to publish and distribute in a more effective way their cultural patrimony over the Internet.
视听内容语义标注的协同系统——在巴西独立文化语境中的应用
这项工作提出了一个支持网络上视听(AV)内容的协作语义注释的体系结构。主要目标是提出一个语义导向的基础设施,以组织由巴西文化点和独立制作人制作的视听材料,以便优化社区电视广播公司、学校、电影协会和互联网的搜索。该合作将依赖于内容注释方案,旨在通过结合与生产中出现的相关场景、区域和对象相关的观点和含义,刺激消费者和生产者丰富整体内容描述。该体系结构基于MPEG-7、语义web概念和本体web语言(OWL)等AV内容描述技术。这项工作认为,合作方式以及巴西正在努力扩大互联网宽带接入的覆盖范围,将促进数字技术在文化表现形式的制作和记录中的传播,使艺术家和实体能够以更有效的方式在互联网上出版和分发他们的文化遗产。
