A QoS broker based architecture for efficient Web services selection
M. A. Serhani, R. Dssouli, A. Hafid, H. Sahraoui
Computer Science
IEEE International Conference on Web Services…
11 July 2005
TLDR
This paper presents a QoS broker-based architecture for Web services to support the client in selecting Web services based on his/her required QoS, and proposes a two-phase verification technique that is performed by a third party broker. Expand

Fingerprinting design patterns
Yann-Gaël Guéhéneuc, H. Sahraoui, Farouk Zaidi
Computer Science
11th Working Conference on Reverse Engineering
8 November 2004
TLDR
It is shown that fingerprints help in reducing the search space of micro-architectures similar to design motifs efficiently using the Composite design motif and the JHotDraw framework. Expand

A Bayesian Approach for the Detection of Code and Design Smells
F. Khomh, S. Vaucher, Yann-Gaël Guéhéneuc, H. Sahraoui
Computer Science
Ninth International Conference on Quality…
24 August 2009
TLDR
This work presents a systematic process to convert existing state-of-the-art detection rules into a probabilistic model and shows that when past detection results are available, this model can be calibrated using machine learning techniques to offer an improved, context-specific detection. Expand

BDTEX: A GQM-based Bayesian approach for the detection of antipatterns
F. Khomh, S. Vaucher, Yann-Gaël Guéhéneuc, H. Sahraoui
Computer Science
J. Syst. Softw.

1 April 2011
TLDR
BDTEX (Bayesian Detection Expert) is presented, a Goal Question Metric based approach to build Bayesian Belief Networks (BBNs) from the definitions of antipatterns and the advantages of BBNs over rule-based models are discussed. Expand

Visualization-based analysis of quality for large-scale software systems
G. Langelier, H. Sahraoui, Pierre Poulin
Computer Science
ASE '05

7 November 2005
TLDR
It is claimed that hybrid techniques that combine automatic analysis with human expertise through visualization are excellent alternatives to them and a visualization framework that supports quality analysis of large-scale software systems is proposed.Expand

Multi-Criteria Code Refactoring Using Search-Based Software Engineering
Ali Ouni, M. Kessentini, H. Sahraoui, Katsuro Inoue, K. Deb
Computer Science
ACM Trans. Softw. Eng. Methodol.
30 June 2016
TLDR
A multi-objective search-based approach for automating the recommendation of refactorings that succeeds in preserving the design coherence of the code, with an acceptable level of code change score while reusing knowledge from recorded refactoring applied in the past to similar contexts is proposed.

Modularization Metrics: Assessing Package Organization in Legacy Large Object-Oriented Software
Hani Abdeen, Stéphane Ducasse, H. Sahraoui
Computer Science
18th Working Conference on Reverse Engineering
17 October 2011
TLDR
A complementary set of metrics that assess some modularity principles for packages in large legacy object-oriented software: Information-Hiding, Changeability and Reusability principles are provided.Expand

Automatic Package Coupling and Cycle Minimization
Hani Abdeen, Stéphane Ducasse, H. Sahraoui, Ilham Alloui
Computer Science
16th Working Conference on Reverse Engineering
13 October 2009
TLDR
A heuristic search-based approach for automatically optimizing inter-package connectivity (i.e., dependencies) based on Simulated Annealing technique to help maintainers improve the quality of software modularization. Expand

Empirical studies to assess the understandability of data warehouse schemas using structural metrics
M. A. Serrano, C. Calero, H. Sahraoui, M. Piattini
Computer ScienceSoftware Quality Journal
1 March 2008
TLDR
An empirical study and a replication aimed at investigating the use of structural metrics as indicators of the understandability of data warehouse schemas show that although a linear model is a good approximation of the relation between structure and understandability, the associated coefficients are not significant enough.

Visual Detection of Design Anomalies
Karim Dhambri, H. Sahraoui, Pierre Poulin
Computer Science
12th European Conference on Software Maintenance…
1 April 2008
TLDR
A visualization-based approach to detect design anomalies for cases where the detection effort already includes the validation of candidates, and shows that performance variability against manual detection is reduced and that the semi-automatic detection has good recall for some anomaly types.
