The need for IT skills assessment and certification is indisputable for both persons and institutions. Thus, the recourse to automatic assessment systems able to answer the strong demand of such assessment or certification is inevitable. In this paper, we propose a new approach to automatically assess IT skills in authentic context. This approach relies on(More)
The Label Propagation Algorithm (LPA) is a fast algorithm for community detection. This algorithm has proved its efficiency and scalability even in large social networks. It is basedonly on updating the label of each node by the most frequent label within its neighbors. However, in case of many maximal labels, a random choice is made. This reduces the(More)
The success of machine learning for automatic speech processing has raised the need for large scale datasets. However, collecting such data is often a challenging task as it implies significant investment involving time and money cost. In this paper, we devise a recipe for building largescale Speech Corpora by harnessing Web resources namely YouTube, other(More)
