A new generation of tools supports the integration of Web 2.0 and semantic Web approaches. Some of these tools-such as Semantic MediaWiki (http://meta.wikimedia. org/wiki/SemanticMediaWiki), BOWiki, (http://onto.eva. mpg.de/bowiki), and Platypus Wiki (http://platypuswiki. sourceforge.net)-provide wiki extensions for creating semantic links between pages. Other tools let users organize tags in some semantic structure, and fully fledged ontology editors such as pOWL support the distributed and collaborative development of ontologies. Commercial tools such as Freebase (http://freebase.com) are also entering the field. Most of these tools are in early development-the collaborative-knowledge-construction field is in its infancy. Few, if any, user studies outline what users expect from such tools and what does or doesn't work. So, we organized the collaborative knowledge construction challenge. The CKC challenge let users try different tools and provide feedback to help us assess the state of the art.

CKC 挑战：探索协作知识构建的工具

新一代工具支持 Web 2.0 和语义 Web 方法的集成。其中一些工具，例如 Semantic MediaWiki (http://meta.wikimedia.org/wiki/SemanticMediaWiki)、BOWiki (http://onto.eva.mpg.de/bowiki) 和 Platypus Wiki (http:// /platypuswiki.sourceforge.net) - 提供用于在页面之间创建语义链接的 wiki 扩展。其他工具让用户以某种语义结构组织标签，而成熟的本体编辑器（如 pOWL）支持本体的分布式和协作开发。Freebase (http://freebase.com) 等商业工具也正在进入该领域。大多数这些工具都处于早期开发阶段——协作知识构建领域还处于起步阶段。很少有（如果有的话）用户研究概述用户对这些工具的期望以及什么有效或无效。所以，我们组织了协作知识构建挑战赛。CKC 挑战让用户尝试不同的工具并提供反馈以帮助我们评估最新技术。
