Social translucence: an approach to designing systems that support social processes

Abstract: We are interested in desiging systems that support communication and collaboration among large groups of people over computing networks. We begin by asking what properties of the physical world support graceful human-human communication in face-to-face situations, and argue that it is possible to design digital systems that support coherent behavior by making participants and their activites visible to one another. We call such systems “socially translucent systems” and suggest that they have three characteristics—visbility, awareness, and accountability—which enable people to draw upon their experience and expertise to structure their interactions with one another. To motivate and focus our ideas we develop a vision of knowledge communities, conversationally based systems that support the creation, management and reuse of knowledge in a social context. We describe our experience in designing and deploying one layer of functionality for knowledge communities, embodied in a working system called “Barbie” and discuss research issues raised by a socially translucent approach to design.

Dynamic behavior-based access control system and method

Abstract: The present invention provides a method for controlling an entity's access to a resource based on observed behavior of the entity. The method assigns the entity a default authorization meta-tag. The method monitors the entity's behavior and updates the entity's meta-tag based upon the observed behavior. Accordingly, dynamic behavior-based access control is achieved.

User-defined online interaction method and device

Abstract: The present invention provides a method, system and apparatus enabling user-defined, genre-structured interaction online. The present invention enables users to define their own genres, including rules of interaction, as well as rules of enforcement. Genre definitions also can include the specification of roles, parameters, and states. The present invention also facilitates a given user to modify a given genre definition. Allowable modifications include addition, modification, and deletion of parameters and interaction and enforcement rules. The present invention also provides dynamically updated graphical representations of the state of genre instances, these graphical representations definable by the users.

Method for translucent online interaction

Abstract: The present invention relates to a method for representing users within an online environment. The method allows users to define environmental parameters for controlling user interaction, define user representation parameters of user data within the environment, capture user data from the users, build an abstract graphical display of the environment, and build a user representation within the abstract graphical display for each user's data.

Method for optimizing information retrieval on the basis of communication relation and program storage device

Abstract: PURPOSE: A method is provided to optimize and to enhance a system performance by chasing user action and a systematic information source showing a communication relation, execution the calculation of data from plural sources of different kinds and constructing the expression of importance of another communicating party concerning a prescribed user. CONSTITUTION: One or plural information sources IS103, one or plural client nodes C101 and one or plural relation analyzers RA104 are connected directly or through a wide area network WAN (102) to Internet. An information source node (103) stores information and can retrieve it when a suitable reference is presented. Thus, the client node (101) prepares a reference to be transmitted to the information source (103) by a user (101) and is connected to the Internet for receiving the result of the reference visually or through an audio means. Further. by introducing the relation analyzer (104), the speed and accuracy of the reference and retrieval tasks can be improved.
