Context-Aware Mobile Collaborative Systems: Conceptual Modeling and Case Study
TLDR
A novel model for Context-Aware Mobile COllaborative Systems (CAMCOS) and a functional architecture based on that model are proposed and a prototype system in the tourism domain was implemented and evaluated. Expand
MARS: Modelling Arenas to Regulate Collaborative Spaces
TLDR
A java-based prototype supporting the MARS regulation model is implemented and a key feature of this model is that it allows one to create complex arenas by composing simple ones. Expand
Reasoning on expressive description logics with arithmetic constraints
TLDR
It is shown that μALCTIO, which is known to be undecidable and that subsumes ALCQIOreg, is inEXPTIME in the case of tree models, and that knowledge base reasoning, TBoxes and ABoxes, can also be decided in EXPTIME. Expand
Towards social regulation in computer-supported collaborative work
TLDR
The main issues on introducing social regulation in computer-supported collaborative work are explored and an infrastructure enabling users to ease the development of regulated collaborative applications is proposed. Expand
A context-aware architecture for improving collaboration of users in Groupware systems
TLDR
A context-aware conceptual model and architecture is proposed for CAGS aimed to improve user collaboration and identify advantages/disadvantages of current means of collaboration and social behaviors that arise when players interact face-to-face or remotely. Expand
Towards a Context-Aware Framework for Improving Collaboration of Users in Groupware Systems
TLDR
A context-aware conceptual model and architecture is proposed for CAGS aimed to improve user collaboration and identify advantages/disadvantages of current means of collaboration and social behaviors that arise when players interact face-to-face or remotely. Expand
Measuring Social Presence in groupware systems
TLDR
A mechanism for designing and measuring an indicator called Social Presence (SP), which allows to represent the relevance of users when they are gradually participating in a collaborative activity, and designed an algorithm to measure social presence from the results of the objectives and tasks associated to a collaborativeActivity. Expand
Usability evaluation of collaborative applications with multimodal user interface
TLDR
This work proposes a form of evaluation from the perspective of usability for evaluating AC with multimodal user interfaces based on usability heuristics and CA mechanisms (communication collaboration coordination and regulation). Expand
Towards a Reasoning Model for Context-aware Systems: Modal Logic and the Tree Model Property
TLDR
This work proposes a reasoning (satisability) algorithm for the multi-modal Km with converse based on the nite tree model property and a Fischer-Ladner construction and provides the corresponding complexity analysis. Expand
Context-Aware Groupware Systems and Video Games: State of the Art
TLDR
This paper surveys the state of the art of CAGS, and particularly of Context-Aware Collaborative Video Games, in order to identify individual and social context information to be used by the next generation of collaborative systems. Expand
