The Context-Dependent Role Model [chapter]

Jorge Vallejos, Peter Ebraert, Brecht Desmet, Tom Van Cutsem, Stijn Mostinckx, Pascal Costanza
2007 Lecture Notes in Computer Science  
Thus, our contextdependent role (CDR) model facilitates expressing interactions between applications in different, possibly conflicting contexts.  ...  Implementing context-dependent behaviour of pervasive computing applications puts a great burden on programmers: Devices need to continuously adapt not only to their own context, but also to the context  ...  The Context-Dependent Role (CDR) Model To address the requirements discussed in the previous section, we now introduce the CDR model for context-dependent adaptations in mobile distributed systems.  ...

Modeling the Role of Context Dependency in the Recognition and Manifestation of Entrepreneurial Opportunity [article]

Murad A. Mithani, Tomas Veloz, Liane Gabora
2019 arXiv   pre-print
The paper uses the SCOP theory of concepts to model the role of environmental context on three levels of entrepreneurial opportunity: idea generation, idea development, and entrepreneurial decision.  ...  The role of contextual-fit in the generation and development of ideas is modeled as the collapse of their superposition state into one of the potential states that composes this superposition.  ...  Acknowledgements This work is funded by grants to Gabora from the Social Sciences and Humanities Research Council of Canada (SSHRC) and the GOA program of the Free University of Brussels.  ...

The semantic-procedural interface model of the self: The role of self-knowledge for context-dependent versus context-independent modes of thinking

Ulrich Kühnen, Bettina Hannover, Benjamin Schubert
2001 Journal of Personality and Social Psychology  
Ile authors proposed the semantic-procedural interface model, which distinguishes 2 such mechanisms.  ...  Independent self-definitions coincide with the tendency to process stimuli unaffected by the context in which they appear.  ...  As predicted by the SPI model, interdependent self-construals coincided with context-dependent thinking.  ...

A combined formal model for relational context-dependent roles

Thomas Kühn, Stephan Böhme, Sebastian Götz, Uwe Aßmann
2015 Proceedings of the 2015 ACM SIGPLAN International Conference on Software Language Engineering  
Currently, there is no role-based modeling language sufficiently incorporating both the relational and context-dependent nature of roles together with the various proposed constraints.  ...  Researchers focused either on relational roles or context-dependent roles rather then combining both natures.  ...  Acknowledgments This work is funded by the German Research Foundation (DFG) within the Research Training Group "Role-based Software Infrastructures for continuous-context-sensitive Systems" (GRK 1907)  ...

Context-Sensitive and Role-Dependent Spoken Language Understanding Using Bidirectional and Attention LSTMs

Chiori Hori, Takaaki Hori, Shinji Watanabe, John R. Hershey
2016 Interspeech 2016  
The different roles of client and agent are modeled by switching between role-dependent layers.  ...  In the present study, we use bidirectional and attention-based LSTMs to train a roledependent context-sensitive model to jointly represent both the local word-level context within each utterance, and the  ...  Acknowledgements The authors thank Prof.  ...

FRaMED: full-fledge role modeling editor (tool demo)

Thomas Kühn, Kay Bierzynski, Sebastian Richly, Uwe Aßmann
2016 Proceedings of the 2016 ACM SIGPLAN International Conference on Software Language Engineering - SLE 2016  
First, most modeling languages focused either on the behavioral, relational or context-dependent nature of roles rather than combining them.  ...  Since the year 1977, role modeling has been continuously investigated as promising paradigm to model complex, dynamic systems.  ...  Acknowledgments This work is funded by the German Research Foundation (DFG) within the Research Training Group "Role-based Software Infrastructures for continuous-context-sensitive Systems" (GRK 1907).  ...

Revocation Schemes for Delegation Licences [chapter]

Meriam Ben-Ghorbel-Talbi, Frédéric Cuppens, Nora Cuppens-Boulahia, Adel Bouhoula
2008 Lecture Notes in Computer Science  
Our model supports a wide spectrum of revocation dimensions such as propagation, dominance, dependency, automatic/user revocation, transfer revocation and role/permission revocation.  ...  The paper presents revocation schemes in role-based access control models. We are particularly interested in two key issues: how to perform revocation and how to manage the revocation policy.  ...  We define for this purpose the contexts Ancestor Dependent ad L and ad R to revoke a licence and a role, respectively: We can also define the context Role Dependent (rd) to say that any user empowered  ...

Instance Management Problems in the Role Model of Hozo [chapter]

Kouji Kozaki, Satoshi Endo, Riichiro Mizoguchi
2008 Lecture Notes in Computer Science  
For knowledge (instances model) representation based on ontology and its use, it is desirable to understand phenomena in the target world as precisely as possible.  ...  Especially, establishment of the instance management method of role concept based on the ontological theory is an important subject.  ...  Our role model also supports role concepts depending on multiple contexts [4] .  ...

Context-sensitive access control model for business processes

Goran Sladic, Branko Milosavljevic, Zora Konjovic
2013 Computer Science and Information Systems  
In order to efficiently define and enforce access control for different business processes, the COBAC model is based on the RBAC (Role-based Access Control) model which is extended with the following entities  ...  The COBAC's context model can describe rich context information and can be easily extended for specific cases.  ...  The article [34] presents a context-dependant authorization model for collaborative access control.  ...

Multi-model-based Access Control in Construction Projects

Frank Hilbert, Raimar J. Scherer, Larissa Araujo
2012 Electronic Proceedings in Theoretical Computer Science  
Dynamic dependencies to the project context as well as static dependencies on the organizational structure are mapped in a context-sensitive rule.  ...  Furthermore, the model size can lead to a delay in communication. In this paper an approach is presented for defining model cut-outs according to the current project context.  ...  therefore be context-dependently modelled and dynamically evaluated.  ...

A Model of Derived Roles [chapter]

Kouji Kozaki, Yoshinobu Kitamura, Riichiro Mizoguchi
2012 Lecture Notes in Computer Science  
This paper focuses on roles which are dependent on the future or past event/process, such as candidate, departing passenger, murderer, and product etc.  ...  In order to deal with such kinds of roles based on an ontological theory of roles, we introduce a model of derived roles with its temporal model.  ...  Acknowledgement The authors are grateful for Nicola Guarino  ...
