中文摘要：

知识具有默会性和情境依赖性，默会知识的交流、共享与情境密切相关．默会知识的共享实质上是一个知识创造的过程，只有亲临现场、共同在场、互动沟通，才能有效地传递与分享默会知识，并基于此创造知识信息化为知识共享创造了条件，有利于促进知识共享，但非结构化的问题难以通过信息化的手段进行处理，信息系统在共享默会知识、情境依赖性知识时往往无能为力，永远都无法完全替代主体共同在场的面对面的互动沟通．因此，为实现情境依赖性的默会知识充分共享并创造知识，即使在信息化的背景下，也有必要进行共同在场的沟通．

英文摘要：

Knowledge possesses the attributes of tacitness and context-dependency. The communication and sharing of tacit knowledge is closely related with context. Actually, tacit knowledge sharing is a process of knowledge creation, only by the ways of being present in person and inter-communication, can the tacit knowledge be transferred and shared. Though informatization has created favorable conditions to advance knowledge sharing, it is very difficult to settle down the non-structured problems by informatization. Information system loses frequently efficacy in sharing tacit and context dependent knowledge. Information system does ever not substitute for face-to-face communication. Thus, to share the tacit and context dependent knowledge, it is absolutely necessary for the communicators to be co-present even in the background of informatization.
