ABSTRACT Stereotypes and clustering are some techniques for creating user models from user behavior. Yet, they possess important risks as users actions could be misinterpreted or users could be associated with undesirable profiles. It could be worst if users' actions, beliefs, and comments are long term stored such as in Organizational Memory Systems (OMS) where users' contributions are available to the whole organization. We propose a privacy model based on four privacy roles that allow users to control the disclosure of their personal data and, when recovered, blurs such data as time passes.

    ABSTRACT: People are usually concerned with the privacy of their personal information. However, the problem of privacy is also present when the information is directly linked to people, for example in personal opinions, discussions and decisions. Typically, if this information is indefinitely stored in an organizational memory system, then it may cause privacy problems inside the organization. Privacy is needed for users to feel free enough to express themselves honestly, and consequently, for the collaborative software to succeed. This paper presents a model to incorporate automatic privacy measures in an Organizational Memory System.

    ABSTRACT: The use of past information is becoming critical for organizations. Coordination, decision making and negotiation are some of the collaborative activities that depend on it. However, the need to provide privacy and information retrieval capabilities to all users of an organizational memory system (OMS), requires a good strategy for acquiring and structuring the information. This paper presents a strategy intended to (a) facilitate the feeding of an OMS based on information stored in legacy information systems, (b) ease the information retrieval process, and (c) provide an automatic privacy mechanism for the information stored in the OMS.

    ABSTRACT: Collaborative activities such as coordination, decision-making and negotiation critically depend on historical information of an organization. This information is usually part of isolated legacy information systems, therefore, it can be inconsistent, redundant and difficult to retrieve and link. Previous research in CSCW has proposed the use of Organizational Memory Systems (OMS) to accumulate, organize, preserve, link and share diverse information coming from various sources, and thus support such collaborative activities. However, there is a need to provide a low-cost feeding process, to embed privacy mechanisms and to support information retrieval capabilities for all users of the OMS, in order to make these solutions useful to a broad range of organizations. As a way to deal with this need, this paper presents a transformational model able to: (a) facilitate the feeding of an OMS based on information stored in legacy information systems, (b) ease the information retrieval process, and (c) embed automatic mechanisms to evolve the information stored in the OMS, through a document privacy lifecycle. This is a low-cost solution that can be implemented using OpenSource technologies.
