Abstract : Collaborative knowledge sharing systems (CKS systems) are groupware applications that allow on-line communities to share knowledge. These systems provide shared computational workspaces where the community's members can develop a shared knowledge repository (KR). Unfortunately, when comparing knowledge-sharing face-to-face or even lightweight groupware supported, CKS systems' activity seems forced, a little motivating and artificial. Because one of the problems with current knowledge repository systems is that they consider the knowledge-sharing activity as the centralized accumulation of information rather than as a process by means of which the group develops a common understanding (builds knowledge) and where knowledge divergence can take place.
In this research, I study knowledge-sharing communities, how they share knowledge and, in particular, I focus on the occurrence of knowledge divergence. Knowledge divergence means a cognitive conflict at the common understanding level and it is expressed through the generation of alternatives, arguments and different points of view about a conceptualization of a topic of interest. In this context, knowledge-sharing activity is seen as an evolutionary process and reflexes the discussion through which the participants reflect on a domain of interest, in order to build a shared conceptualization of their common understanding. In this conception of the knowledge-sharing activity, knowledge divergence occurrence is a common practice.
Assisting people in sharing knowledge and supporting their knowledge divergence can help to improve the conditions of usability of the CKS systems. In this dissertation, I hypothesized that any effort to reach a CKS system, as a groupware application that supports the knowledge-sharing activity, should pay special attention to the discussion activity and the knowledge divergence occurrences in order to improve the conditions of usability of the system. Knowledge-sharing activity puts forward special situations that will become the requirements to CSCW (Computer-Supported Collaborative Work) field and groupware systems. Therefore, the focus of this research is to find out a new CSCW approach that helps to carry out the knowledge-sharing activity with knowledge divergence occurrence.
I develop a theoretical framework which conceptualizes the knowledge-sharing activity and considers the occurrence of knowledge divergences as a first order element within it. This framework synthesizes the architecture of a CKS system as a groupware application which supports a knowledge-sharing process. This frameworks takes into account the collaboratively and distributed development of a shared KR (the conceptualization of its common understanding), the occurrence and coexistence of a knowledge divergences and the preservation of the autonomy of the participants. In particular, my goals are to show that an monotonic extension of the KR, differentiated workspaces for preserving individual autonomy, appropriately supports to manage knowledge divergence and suitable awareness services for keeping users aware of the knowledge-sharing activity can be framed in a sufficiently operational form to be useful to groupware designers and to improve the conditions of usability of the traditional knowledge-sharing systems.
