This paper reports hepatitis C virus (HCV) prevalence, genotypes and phylogenetic characteristics in 95 haemophilic Tunisian patients. The studied population included 3 groups of patients according to their date of birth: before 1985 when inactivation procedures for clotting factors was introduced, between 1985 and 1994 when systematic anti-HCV screening of Tunisian blood donors was introduced ...

This paper presents a method to understand spoken Tunisian dialect based on lexical semantic. This method takes into account the specificity of the Tunisian dialect which has no linguistic processing tools.

In this paper, we propose TunDiaWN (Tunisian dialect Wordnet) a lexical resource for the dialect language spoken in Tunisia. Our TunDiaWN construction approach is founded, in one hand, on a corpus based method to analyze and extract Tunisian dialect words. A clustering technique is adapted and applied to mine the possible relations existing between the Tunisian dialect extracted words and to gr...

Speech recognition for under-resourced languages represents an active field of research during the past decade. The tunisian arabic dialect has been chosen as a typical example for an under-resourced Arabic dialect. We propose, in this paper, our first steps to build an automatic speech recognition system for Tunisian dialect. Several Acoustic Models have been trained using HMM-GMM and HMM-DNN ...
