Sharing and Privacy-Aware RBAC in Online Social Networks

Ahmad Kamran Malik, Schahram Dustdar
2011 2011 IEEE Third Int'l Conference on Privacy, Security, Risk and Trust and 2011 IEEE Third Int'l Conference on Social Computing  
We present a sharing and privacy-aware SP-RBAC model by extending the well-known RBAC model.  ...  Users share their private information online with other users, which is becoming a serious privacy issue at the social and technical level.  ...  Many different types and names of collaborative relationships can be created by a user.  ...

Modeling of Information Sharing on the Business Social Media

Fujio TORIUMI, Takashi OKADA, Shuichiro YAMAMOTO, Kenichiro ISHII
2013 SICE Journal of Control Measurement and System Integration  
In this research, a simple model of social media is provided, whose users share information by directly referring to other users.  ...  Finally, the authors proposed a method that supports information sharing and evaluated it by agent-based simulation using our proposed model.  ...  All agents have specific objective functions calculated from the information they possess. By repeating information sharing, all agents maximize their objective function values.  ...

Extending the mutual information measure to rank inferred literature relationships

Jonathan D Wren
2004 BMC Bioinformatics  
Herein, we attempt to extend the calculation of mutual information to indirect (i.e. inferable) associations by using the MIM of shared associations.  ...  Objects of general research interest (e.g. genes, diseases, phenotypes, drugs, ontology categories) found within MEDLINE are used to create a network of associations for evaluation.  ...  This work was funded by NSF-EPSCoR grant # EPS-0132534.  ...

Supporting Multidisciplinary Teams in Concurrent Engineering [chapter]

J. H. Maxfield, L. T. P. Fernando, P. M. Dew
1995 IFIP Advances in Information and Communication Technology  
The shared objects, that support collaboration, encapsulate product information in a standard format based on the developing draft ISO standard STEP (a standard for the exchange of product data).  ...  This architecture integrates a multiperspective distributed virtual environment with a standard product model and supports interaction among users through shared objects.  ...  ACKNOWLEDGEMENTS The authors would like to thank the members of the DVE project and the Keyworth Institute of Manufacturing and Information Systems Engineering for supporting this work.  ...

Dynamic Collaborations for Information Sharing within and across Virtual Teams

Ahmad Kamran Malik, Schahram Dustdar
2011 2011 Frontiers of Information Technology  
In such a dynamic environment, information sharing and privacy are critical issues for users, their teams and enterprises.  ...  We present a Dynamic Sharing and Privacy-aware Role-Based Access Control (DySP-RBAC) model that extends the RBAC model for enhanced sharing and privacy of information among collaborating users within and  ...  This is controlled by sharing data elements (CR, AL) in DySP-RBAC. Due to many to many team-task relation, a task can be created mutually by many teams.  ...

An Overview of Repository Technology

Philip A. Bernstein, Umeshwar Dayal
1994 Very Large Data Bases Conference  
A repository is a shared database of information about engineered artifacts.  ...  We also discuss how to implement a repository manager by layering it on a DBMS, focusing especially on issues of programming interface, performance, distribu-,;  ...  Over the lifecycle of engineered artifacts, many objects of many di@erent types are defined, created, manipulated, and managed by a variety of tools that need to share data.  ...

Adaptive software cache management for distributed shared memory architectures

John K. Bennett, John B. Carter, Willy Zwaenepoel
1990 SIGARCH Computer Architecture News  
An adaptive cache coherence mechanism exploits semantic information about the expected or observed access behavior of particular data objects.  ...  We have found that the access patterns of a large percentage of shared data objects fall in a small number of categories for which e cient software coherence mechanisms exist.  ...  The improvement is caused by the fact that Quicksort performs many writes to shared data objects between synchronization points, so many updates to the same data object are combined before they are eventually  ...

Dynamic information processing states revealed through neurocognitive models of object semantics

Alex Clarke
2014 Language, Cognition and Neuroscience  
These object-specific representations require the integration of shared and distinguishing object properties and support the unique recognition of objects.  ...  Recognising objects relies on highly dynamic, interactive brain networks to process multiple aspects of object information.  ...  Semantic features can occur in a variable number of concepts, and can be loosely distinguished as being shared by many other concepts (e.g. has ears, has legs are features shared by many animals) or more  ...
