New trends from libre software that may change education E-learning
Informal learning
Libre software
Open source
2011 IEEE Global Engineering Education Conference, EDUCON 2011 English 2011 Libre software, also known as Open Source Software or Free Software, has already changed the way we know education. This influence goes from content-with examples such as the Wikipedia-, openness -for instance, the OCW- or tools -like learning management systems or desktop applications. In this paper, we introduce some new trends that are inspired in the libre software movement and that may change education in the near future. Among others, experiences such as the OpenSE project -where students can be free learners outside of any type of formal educational context- or the p2p University -an online community of open study groups for short university-level courses- will be presented and discussed. 0 0
A quantitative approach to the use of the Wikipedia English 2009 This paper presents a quantitative study of the use of the Wikipedia system by its users (both readers and editors), with special focus on the identification of time and kind-of-use patterns, characterization of traffic and workload, and comparative analysis of different language editions. The basis of the study is the filtering and analysis of a large sample of the requests directed to the Wikimedia systems for six weeks, each in a month from November 2007 to April 2008. In particular, we have considered the twenty most frequently visited language editions of the Wikipedia, identifying for each access to any of them the corresponding namespace (sets of resources with uniform semantics), resource name (article names, for example) and action (editions, submissions, history reviews, save operations, etc.). The results found include the identification of weekly and daily patterns, and several correlations between several actions on the articles. In summary, the study shows an overall picture of how the most visited language editions of the Wikipedia are being accessed by their users. 0 0
On the Analysis of Contributions from Privileged Users in Virtual Open Communities Libre software
Wikipedia
HICSS English 2009 Collaborative projects built around virtual communities on the Internet have gained momentum over the last decade. Nevertheless, their rapid growth rate rises some questions: which is the most effective approach to manage and organize their content creation process? Can these communities scale, controlling their projects as their size continues to grow over time? To answer these questions, we undertake a quantitative analysis of privileged users in FLOSS development projects and in Wikipedia. From our results, we conclude that the inequality level of user contributions in both types of initiatives is remarkably distinct, even though both communities present almost identical patterns regarding the number of distinct contributors per file (in FLOSS projects) or per article (in Wikipedia). As a result, totally open projects like Wikipedia can effectively deal with faster growing rates, while FLOSS projects may be affected by bottlenecks on committers who play critical roles. 0 1
On the Inequality of Contributions to Wikipedia English 2008 Wikipedia is one of the most successful examples of massive collaborative content development. However, many of the mechanisms and procedures that it uses are still unknown in detail. For instance, how equal (or unequal) are the contributions to it has been discussed in the last years, with no conclusive results. In this paper, we study exactly that aspect by using Lorenz curves and Gini coefficients, very well known instruments to economists. We analyze the trends in the inequality of distributions for the ten biggest language editions of Wikipedia, and their evolution over time. As a result, we have found large differences in the number of contributions by different authors (something also observed in free, open source software development), and a trend to stable patterns of inequality in the long run. 0 5
Quantitative analysis and characterization of Wikipedia requests WikiSym English 2008 Our poster describes the quantitative analysis carried out to study the use of the Wikipedia system by its users with special focus on the identification of time and kind-of-use patterns, characterization of traffic and workload, and comparative analysis of different language editions. By filtering and classifying a large sample of the requests directed to the Wikimedia systems over 7 days we have been able to identify important information such us the targeted namespaces, the visited resources or the requested actions. The results found include the identification of weekly and daily patterns, and several correlations between different actions on the articles. In summary, the study shows an overall picture of how the most visited language editions of the Wikipedia are being accessed by their users. 0 0

Wikipedia
Communications in Computer and Information Science English 2008 In a few years, Wikipedia has become one of the information systems with more public of the Internet. Based on a relatively simple architecture it has proven to be capable of supporting the largest and more diverse community of collaborative authorship worldwide. Using a quantitative methodology, (analyzing public Wikipedia databases), we describe the main characteristics of the 10 largest language editions, and the authors that work in them. The methodology is generic enough to be used on the rest of the editions, providing a convenient framework to develop a complete quantitative analysis of the Wikipedia. Among other parameters, we study the evolution of the number of contributions and articles, their size, and the differences in contributions by different authors, inferring some relationships between contribution patterns and content. These relationships reflect (and in part, explain) the evolution of the different language editions so far, as well as their future trends. 0 0
The Top Ten Wikipedias: A quantitative analysis using WikiXRay Wikipedia ICSOFT 2007, July 2007. Barcelona, Spain 2007 In a few years, Wikipedia has become one of the information systems with more public (both producers and consumers) of the Internet. Its system and information architecture is relatively simple, but has proven to be capable of supporting the largest and more diverse community of collaborative authorship worldwide. In this paper, we analyze in detail this community, and the contents it is producing. Using a quantitative methodology based on the analysis of the public Wikipedia databases, we describe the main characteristics of the 10 largest language editions, and the authors that work in them. The methodology (which is almost completely automated) is generic enough to be used on the rest of the editions, providing a convenient framework to develop a complete quantitative analysis of the Wikipedia. Among other parameters, we study the evolution of the number of contributions and articles, their size, and the differences in contributions by different authors, inferring some relationships between contribution patterns and content. These relationships reflect (and in part, explain) the evolution of the different language editions so far, as well as their future trends. 0 0
