TED (Technology, Entertainment, Design, www.ted.com/) Talks has been one of the most popular video systems. However, the current TED Talks system expressed its inquired videos as in a two-dimensional (2D) table, which is inconvenient for searching the relationships among videos and tags. This study converts the TED Talks table into a sphere by using optimization techniques to help users search for preferred videos.,There are five phases in this study as follows. Phase 1: Reorganize data of 36 tags and 108 videos; Phase 2: Allocate tags on the TED sphere; Phase 3: Allocate videos on the TED sphere; Phase 4: Develop an online interactive TED retrieval system; and Phase 5: Perform survey and evaluation.,One survey demonstrated that the TED Talks sphere is more convenient for searching videos, as it is more user-friendly because of its graphical user interface, more convenient to use, more useful for retrieving information and can facilitate a more responsive search for users’ preferred videos.,The numbers of tags and videos able to be displayed on a sphere is limited by the capacity of an optimization software and hardware.,The proposed sphere system can be used by a large number of users of TED Talks groups.,This sphere systems can also be applied to other fields which use 2D forms to display the relationships among objects.,This study uses an optimization method to convert a 2D form into a 3D sphere to highlight the relationships among numerous objects.

形成一个 TED 演讲圈，方便搜索

TED（技术、娱乐、设计，www.ted.com/）Talks 一直是最受欢迎的视频系统之一。然而，目前的TED Talks系统将其查询的视频表达为二维（2D）表格，不方便搜索视频和标签之间的关系。本研究通过使用优化技术将 TED Talks 表转换为球体，帮助用户搜索喜欢的视频。本研究分为以下五个阶段。第一阶段：重组36个标签和108个视频的数据；阶段 2：在 TED 球体上分配标签；第 3 阶段：在 TED 领域分配视频；第四阶段：开发在线互动TED检索系统；和阶段 5：进行调查和评估。，一项调查表明 TED Talks 领域更方便搜索视频，
