Hierarchical Reorganization of Dimensions in OLAP Visualizations
Found in: IEEE Transactions on Visualization and Computer Graphics
By S. Lafon,F. Bouali,C. Guinot,G. Venturini
Issue Date:November 2013
pp. 1833-1845
In this paper, we propose a new method for the visual reorganization of online analytical processing (OLAP) cubes that aims at improving their visualization. Our method addresses dimensions with hierarchically organized members. It uses a genetic algorithm...
 
Visual and Interactive Exploration of a Large Collection of Open Datasets
Found in: 2013 17th International Conference on Information Visualisation
By T. Liu,D. Bangash Ahmed,F. Bouali,G. Venturini
Issue Date:July 2013
pp. 285-290
We deal in this paper with the problem of creating an interactive and visual map for a large collection of Open datasets. We first describe how to define a representation space for such data, using text mining techniques to create features. Then, with a si...
 
3D and Immersive Interfaces for Business Intelligence: The Case of OLAP
Found in: 2013 17th International Conference on Information Visualisation
By S. Lafon,F. Bouali,C. Guinot,G. Venturini
Issue Date:July 2013
pp. 272-277
We study in this paper the use of a 3D interface for OLAP. We analyze the state of the art in OLAP 3D visualizations. In a first step, we propose a new interface, called VR4OLAP, that combines the relative advantages of the studied methods. VR4OLAP can vis...
 
Merging Test and Verification for Rule Base Debugging
Found in: Tools with Artificial Intelligence, IEEE International Conference on
By F. Bouali, S. Loiseau, M.C. Rousset
Issue Date:November 1996
pp. 166
A way of formally but partially characterizing knowledge base correctness is to define knowledge base coherency. The first contribution of this paper is to show how taking into account test cases can lead to a new definition of rule base coherency that is ...
 
DataTube4log: A Visual Tool for Mining Multi-threaded Software Logs
Found in: 2014 18th International Conference on Information Visualisation (IV)
By S. Devaux,F. Bouali,G. Venturini
Issue Date:July 2014
pp. 189-195
In this paper we study a 3D tubular visualization of software activity log data, with the aim of supporting multithreaded software development and debugging. We consider an existing visualization called Datatube2 that has already been used to help various ...
 
Visual and interactive analysis of a large collection of open data with the relative neighborhood graph
Found in: Proceedings of the 6th International Symposium on Visual Information Communication and Interaction (VINCI '13)
By F. Bouali, G. Venturini, T. Liu
Issue Date:August 2013
pp. 109-110
We deal in this paper with the problem of creating an interactive and visual map for a large collection of Open datasets. We first describe how to define a representation space for such data. We use text mining techniques to create features. Then, with a s...
     
Visualizing a large collection of open datasets: an experiment with proximity graphs
Found in: Proceedings of the 2nd International Workshop on Open Data (WOD '13)
