The introduction or new communication and information technologies in work communities has primarily been used to crete new channels of communication andℜ the cost or communication among members in the workplace. Ironically, the pervasiveness of individuals to discern social structures. Fortunately, information technologies that Tie responsible for triggering this problem can also be used to overcome these obstacles. Beciuse new generation of software called “collaborative filters” or “comniumtyware” (C ontnctoi O’Keefe, & Jones, 1997; Kautz, Selman, & Shah, 1997) can be used to make visible the work communities’ virtual social structure. One such tool, IKNOW (Inquiring Knowledge Networks On the Web; http://iknow.spcomm.uiuc.edu/), has been designed by a team of UIUC researchres to assist individuals to search the organization’s databases to automatically answer questions about the organization’s knowledge network, that is, “Who knows what?” as well as questions about the organization’s cognitive knowledge networks, that is, “Who knows who knows what?” within the organization. Unlike traditional web search engines that help an individual search for content on the web, tools such as IKNOW search for content and contacts (direct and indirect). In addition to being instantly beneficial to users, they also provide the researcher with an opportunity to unobtrusively and reliably study the influence of communityware on the co-evolution of knowledge networks.
