Knowledge plays an increasingly important role in business, company, and organization,it is the ability for organization to learn and assimilate new knowledge in orderto make plans or business progresses. However, when comes to the tacit knowledge,in most cases, as Polanyi (1969) said ”we can know more than we can tell”, whichmeans in our daily lives, most of the knowledge stored in our brain can not be expressedout to others easily, we call this kind of knowledge ”tacit”. Therefore, tacitknowledge holds most part of our knowledge - and at the same time - harder to identifyand share.There is an popular approach called ’Community of Practice (CoP)’ which aimsat creating and sharing knowledge through informal practicing and learning. Thus,in this study, a qualitative research is desired to be made on the approach of communityof practice as well as its effects on tacit knowledge sharing. The purpose of thisstudy is to understand the pattern of sharing tacit knowledge among communitieswith social communication technologies (Tencent QQ) embedded, and to explorethe mechanisms of generating and transferring tacit knowledge with ”community ofpractice”.

Graphs currently attract an increasing number of computer scientists due to their widely adoptions in different areas. However, when people perform graph drawing, one of the most critical issues they need to concern is atheistics, i.e., to make the graph more suitable for human perceptions. In this work, we will aim at exploring one specific kind of graph ''planar st-graphs'' with space-filling technique in Info Vis area. We would cover edge crossing elimination, layer assignment, graph drawing algorithms, and new development of space-filling technique in planar st-graphs drawing etc. The final aim of this project is to develop a new algorithm to draw planar st-graphs based on a space-filling visualization approach with minimum edge crossings and maximum space usage.
