Thèse de doctorat : Università della Svizzera italiana, 2013 ; 2013INFO003.

Our thesis is that the analysis of unstructured data supports software understanding and evolution analysis, and complements the data mined from structured sources. To this aim, we implemented the necessary toolset and investigated methods for exploring, exposing, and exploiting unstructured data.To validate our thesis, we focused on development email data. We found two main challenges in...

On the evolution of source code and software defects

D'Ambros, Marco ; Lanza, Michele (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2010 ; 2010INFO007.

Software systems are subject to continuous changes to adapt to new and changing requirements.This phenomenon, known as software evolution, leads in the long term to software aging: The size and the complexity of systems increase, while their quality decreases. In this context, it is no wonder that software maintenance claims the most part of a software system's cost.The analysis of software...
