在2008年美国总统大选中，潜在的候选人广泛使用YouTube来发布视频材料。我们开发了一个可扩展的系统，可以转录这些材料，并使内容可搜索（通过索引元数据和视频文本），并允许用户根据内容浏览视频材料。该系统既可以作为谷歌的小工具，也可以作为实验室的产品（labs.google.com/gaudi）。考虑到大的暴露，特别强调了系统的可伸缩性和可靠性。本文介绍了该系统的设计与实现。
In the 2008 presidential election race in the United States, the prospective candidates made extensive use of YouTube to post video material. We developed a scalable system that transcribes this material and makes the content searchable (by indexing the meta-data and transcripts of the videos) and allows the user to navigate through the video material based on content. The system is available as an iGoogle gadget1 as well as a Labs product (labs.google.com/gaudi). Given the large exposure, special emphasis was put on the scalability and reliability of the system. This paper describes the design and implementation of this system.
