Cultural analysis of Wikipedia


I'm working under the paper devoted to cultural differences in Wikipedia. Therefore, i have done some literature research where i found some interesting resources devoted to this topic. Following I'm sharing them with you. 
Wikipedia has been found in early 2001 and since then has been one of the most successful and referenced source of knowledge with a qualitative information[1]. The open Encyclopedia can include opinions of any person wherever she geographically located. Wikipedia is organized in such a way that any culture can open its Wikipedia and use its own language for providing content.
According to Hofstede (1991) "culture is the collective programming of the mind which distinguish[sic] one group of people from the other"(Hofstede, 1991). Cultural patterns together create a complex culture structure that can be examined through studying cultural dimensions (Hall, 1976; 1983; Hofstede, 1991; Kluckhohn and Strodbeck 1961; Trompenaars & Hampden-Turner, 1998). Hofstede defined 5 dimensions of culture and calculate empirically dimension rates of many nationalities in the World. The dimensions has become recently a standard framework for cross-cultural research projects. Some works about Wikipedia cross-cultural nature use Hofstede’s dimensions. Courtesy behaviors in the Eastern Wikipedia are explained by high value of power distance and preferable collective work (Hara et al., 2010).  They claimed that authors from Western Wikipedia have more conflict and disagreement behaviors. Moreover, they argue that patterns of author behavior differ in the size of Wikipedia. They analyzed only 4 Wikipedia of various sizes focusing on differences between eastern and western cultures.
Hofstede’s dimensions were used in measuring the quality of the article game (Pfeil et al., 2006). The researchers analyzed the Wikipedia article from French, German, Japanese and Dutch Wikipedia. They found that even if cultures have positively correlated Hofstede's dimensions, Wikipedia quality criteria of considered Wikipedia are different. More evidence of cultural influence in Wikipedia was found by Pembe & Bingol (2006) during comparing linguistic structures of English and German Wikipedia. Although the English Wikipedia is larger; the German Wikipedia included at that point more words associated with family concept.
Rask (2007) analyzed differences between aspects of Wikipedia in developed and developing countries. He considered the number of contributors and edits per articles from different countries and concluded that richer countries profit more on the knowledge shared in Wikipedia. Rask compared different Wikipedia from the economical point of view using the human development index[2] in his observations.
The attempts to define cultural patterns include examination of Wikipedia user talks and talk contents, contents of articles and numbers of edits. In this paper we focus on a still untouched area for cultural patterns in Wikipedia. We observe author networks over the course of time and differentiate between registered and anonymous authors. Moreover, the geographical location of authors and their migrations to other countires is taken into consideration. Furthermore, we find Wikipedia users contributing to several Wikipedia and analyze their behavior and geographical location. These and other findings devoted to Wikipedia growth and editing behaviors are used to define cultural patterns.
Voss (2005) was the first who as many other researchers analyzed fundamentals of Wikipedia and their networks. His main focus was on the German Wikipedia and its graph of links. He showed that the Wikipedia network is scale-free (Barabási et al., 1999). Moreover, Voss found that the number of user talk pages is much higher in Japanese than in German, Danish or Croatian Wikipedia although he left questions concerning cultural differences of Wikipedia unanswered. 
In the next section, we consider name existing research works examining Wikipedia networks. Later, we present our methodology, and afterwards explain the data set we are using. The results include findings about authors, their behaviors, author networks, and articles. The paper concludes with a discussion and an outlook on future work. 

Dynamic development of Wikipedia network

Dynamic development of networks was in the focus by many works (Klamma and Haasler, 2008a, 2008b; Capocci et. al, 2006, Zlatic et. al, 2006). Klamma and Haasler (2008a, 2008b) visualized different Wiki projects (Berlin Wiki, Google Wiki, Aachen Wiki) and observed their changes over the course of time. They found that registered users often serve as connectors in networks of anonymous users. Moreover, they showed that a tiny number of Wikipedia contributors created or edited the majority of articles. Klamma and Haasler created Wikiwatcher tool that can be used for retrieving Wikipedia data, visualize their networks and calculate simple SNA values.
Analysis of Wikipedia as complex networks reveals that the growth of Wikipedia happens according to the preferential attachment (Barabási et al, 1999). Capocci et. al, (2006) showed similarities of evolution patterns of complex networks of WWW and different Wikipedia: new nodes are more probably connected with existed nodes with high degrees of connections. Zlatic et. al (2006) examined 11 Wikipedia networks of articles. The researchers concentrated on article network measures and its comparison. They argue that the growth of Wikipedia networks is unique for different language versions of Wikipedia.
