Automatic Harvesting, Indexing and Provision of Open Access Figures from the fields of Engineering and Technology Using the Infrastructure of Wikimedia Commons and Wikidata

多媒体对象，特别是图像和图形，对于研究结果的可视化和解释是必不可少的。在开放获取条件下，这些科学对象的分发和重复使用得到了显著改善，例如在维基百科文章、研究文献以及教育和知识传播中，图像的许可通常是一个严重的障碍。由于标准化的索引，科学出版物可以通过图书馆门户网站或其他在线搜索服务进行检索，但尚未有针对性地检索和访问附带的图像和数字。因此，非常需要为这些多媒体开放获取对象开发标准化的索引方法，以便提高对这些材料的可达性。为了实现这一目标，有必要开发一种自动采集和索引多媒体开放存取对象的过程。Wikimedia Commons由Wikimedia Foundation运营，是最重要的开放获取媒体收藏之一，也是收获和分发这些收藏的平台和服务。Wikimedia Commons收集免费许可的对象，主要是图像和图形，包括它们的元数据，并将它们提供给Wikipedia和所有其他网络用户。该项目的目标是利用Wikimedia Commons和Wikidata的基础设施，开发一种自动收集和索引来自工程和技术领域受质量控制的开放获取期刊的文章(包括其图像和图形)的过程。为实现这一目标，计划收集科学出版物，并随后提取和丰富所附图像和数字的元数据，以生成标准化索引。该项目的主要成果将是提供信息服务，改进工程和技术领域免费许可图像和数字的检索和获取。

Multimedial objects, especially images and figures, are essential for the visualization and interpretation of research findings. The distribution and reuse of these scientific objects is significantly improved under open access conditions, for instance in Wikipedia articles, in research literature, as well as in education and knowledge dissemination, where licensing of images often represents a serious barrier.Whereas scientific publications are retrievable through library portals or other online search services due to standardized indices there is no targeted retrieval and access to the accompanying images and figures yet. Consequently there is a great demand to develop standardized indexing methods for these multimedial open access objects in order to improve the accessibilty to this material. To address the objective it is necessary to develop a process for automatic harvesting and indexing of multimedial open access objects. Wikimedia Commons, operated by the Wikimedia Foundation, is one of the most important open access media collections and a platform and service for the harvesting and distribution thereof. Wikimedia Commons collects freely licensed objects, mainly images and figures, including their metadata and provides them to Wikipedia and all other web users.It is the aim of this project to develop a process for the automatic harvesting and indexing of articles including their images and figures derived from quality controlled open access journals in the fields of engineering and technology, using the infrastructure of Wikimedia Commons and Wikidata. To reach this goal it is planned to harvest scientific publications and subsequently extract and enrich the metadata of the accompanying images and figures in order to generate a standardized index.The main outcome of the project will be the provision of an information service which improves the retrieval of and the access to freely licenced images and figures from the fields of engineering and technology.
