Access Control for Sharing Semantic Data across Desktops

Ekaterini Ioannou, Juri Luca De Coi, Arne Wolf Koesling, Daniel Olmedilla, Wolfgang Nejdl
2007 International Semantic Web Conference  
We discuss different kinds of policies to specify protection for desktop data and metadata, and describe our access control system to express and execute these policies efficiently.  ...  Obviously, sharing desktop data with co-workers raises privacy and access control issues which have to be addressed. In this paper we discuss these issues, and present appropriate solutions.  ...  for the update of this structure in order to face the evolution of desktop data and metadata.  ...

Lifecycle Knowledge Management: Getting the Semantics Across in X-Media [chapter]

Steffen Staab, Thomas Franz, Olaf Görlitz, Carsten Saathoff, Simon Schenk, Sergej Sizov
2006 Lecture Notes in Computer Science  
Core to this endeavour is the combination of information extraction with formal ontologies as well as with semantically lightweight folksonomies.  ...  In this paper we present some semantic web technologies of the EU integrated project X-Media that build bridges between the various information sources, the different media, the stations of knowledge management  ...  Corresponding to the mentioned examples we distinguish three kinds of data: Private data has no tags for which access rights are defined. Publicly shared data is freely accessible.  ...

Understanding Personal Data as a Space - Learning from Dataspaces to Create Linked Personal Data

Laura Dragan, Markus Luczak-Rösch, Nigel Shadbolt
2014 Extended Semantic Web Conference  
In this paper we argue that the space of personal data is a dataspace as defined by Franklin et al.  ...  We define a personal dataspace, as the space of all personal data belonging to a user, and we describe the logical components of the dataspace.  ...  Conclusion A personal dataspace is the space of a user's entire personal data, regardless of where it is located, on the desktop or on the Web; integrated in a Semantic Desktop, or fragmented across many  ...

Tracking semantic relationships for effective data management in home networks

Ashok Anand, Aaron Gember, Aditya Akella, Vyas Sekar
2010 Proceedings of the 2010 ACM SIGCOMM workshop on Home networks - HomeNets '10  
Many recent proposals have emphasized the importance of data management in home networks and proposed mechanisms for managing replicas across devices to increase availability.  ...  In this paper, we have highlighted several candidate designs and system-optimizations that can help build an effective semantic-aware data management for home networks.  ...  In practice, users are likely to place controls on who can access specific data (e.g., access controls for kids, visitors etc.).  ...

User interface models for the cloud

Hubert Pham
2010 Adjunct proceedings of the 23nd annual ACM symposium on User interface software and technology - UIST '10  
The model's key feature is a lightweight mechanism to group objects for resource organization, sharing, and access control, towards the goal of providing simple semantics for a wide range of tasks, while  ...  This paper proposes a new user interface model that accounts for cloud applications, incorporating representations of people and new gestures for sharing and access, while minimizing the prominence of  ...  As networking and file servers became prominent, the desktop metaphor evolved very little to support sharing and access control.  ...

What About Partners?

Diane Wiessinger
2009 Journal of Human Lactation  
The security implications and requirements of the social semantic desktop are discussed and explained. We give a possible scenario and architectural solutions.  ...  The NEPOMUK architecture assembles the different understandings in the project to reach a common description of the structure, abstractions and relations of the social semantic desktop main aspects.  ...  Its main functionality is to store locally (and when necessary synchronize) user identities, group memberships, access keys (for both communities and groups) and manage the access control for the shared  ...

A Semantic Context Management Framework on Mobile Device

Dexter H. Hu, Fan Dong, Cho-Li Wang
2009 2009 International Conference on Embedded Software and Systems  
We present a semantic context management framework named ContextTorrent, which can make various types of context information be semantically searchable and sharable among local and remote context-aware  ...  Three embedded database systems were evaluated for storing ontology represented contexts in the resource-constrained mobile devices.  ...  ContextTorrent supports fine-grained synchronization control on shared data.  ...

The Organiser - A Semantic Desktop Agent based on NEPOMUK

Sebastian Faubel, Moritz Eberl
2014 International Semantic Web Conference  
In this paper we introduce our NEPOMUK-based Semantic Desktop for the Windows platform.  ...  It uniquely features an integrative user interface concept which allows a user to focus on personal information management while relying on the Property Projection agent for semi-automated file management  ...  Semantic Web technologies, specifically the Semantic Desktop [6] , offer a suitable platform for this purpose.  ...
