Summary: | It gives us great pleasure to introduce the three best papers selected from the papers presented at CLEI 2006 in Santiago, Chile. Following well established tradition, CLEI invited the top papers of the conference for consideration as best papers in a special issue of the CLEI Electronic Journal. For the purpose of selecting these papers, the Comité Directivo of CLEI named a committee consisting of Diego Andrade (Ecuador), Ernst Leiss (USA), José Carlos Maldonado (Brazil), Marcello Visconti (Chile); and Adenilso Simão (Brazil). After a careful review of the ranking obtained from the Program Committee of CLEI 2006, the group agreed to invite six papers. The authors of four papers decided to accept our invitation. These papers were subjected to a further review resulting in the three papers that form this special issue.
On behalf of the selection committee, we would like to thank all people involved in this undertaking, from the authors to the reviewers, and also the SBC – Sociedade Brasileira de Computação for providing the submission system
