The first was at SIGIR 2002 on the topic of “Cross Language Information Retrieval: A Research Roadmap”. The second was at SIGIR 2006 on the topic of “New Directions in Multilingual Information Access”. Over the past decade the field has matured and real world applications have appeared. Thus our goal in this 2009 workshop was to collate experiences and plans for the real-world application of multilingual technology to information access. Our aim is to identify the remaining barriers to practical multilingual information access, both technological and from the point of view of user interaction. We were fortunate to obtain as invited keynote speaker Dr Ralf Steinberger of the Joint Research Centre of the European Commission, presenting the Joint Research Centre's multilingual media monitoring and analysis applications, including NewsExplorer. Dr. Steinberger has written an overview paper about their family of applications, which is the first paper in these proceedings. In our call for papers we specified two types of papers, research papers and position papers. Of the 15 papers initially submitted, two were withdrawn and two were rejected. We accepted 3 research papers and 8 position papers, covering topics from evaluation (of image indexing and of cross-language information retrieval in general), Wikipedia and trust, news site characterization, multilinguality in digital libraries, multilingual user interface design, access to less commonly taught languages (e.g. Indian subcontinent languages), implementation and application to health care. We believe these papers represent a cross-section of the work remaining to be done in moving toward full information access in a multilingual world. We would like to thank our program committee who read, reviewed and wrote reviews under major time constraints (in some cases 2 days).

  • Cultural Anthropology Through the Lens of Wikipedia: Historical Leader Networks, Gender Bias, and News-Based Sentiment
    Cultural Anthropology through the Lens of Wikipedia: Historical Leader Networks, Gender Bias, and News-based Sentiment Peter A. Gloor, Joao Marcos, Patrick M. de Boer, Hauke Fuehres, Wei Lo, Keiichi Nemoto [email protected] MIT Center for Collective Intelligence Abstract In this paper we study the differences in historical World View between Western and Eastern cultures, represented through the English, the Chinese, Japanese, and German Wikipedia. In particular, we analyze the historical networks of the World’s leaders since the beginning of written history, comparing them in the different Wikipedias and assessing cultural chauvinism. We also identify the most influential female leaders of all times in the English, German, Spanish, and Portuguese Wikipedia. As an additional lens into the soul of a culture we compare top terms, sentiment, emotionality, and complexity of the English, Portuguese, Spanish, and German Wikinews. 1 Introduction Over the last ten years the Web has become a mirror of the real world (Gloor et al. 2009). More recently, the Web has also begun to influence the real world: Societal events such as the Arab spring and the Chilean student unrest have drawn a large part of their impetus from the Internet and online social networks. In the meantime, Wikipedia has become one of the top ten Web sites1, occasionally beating daily newspapers in the actuality of most recent news. Be it the resignation of German national soccer team captain Philipp Lahm, or the downing of Malaysian Airlines flight 17 in the Ukraine by a guided missile, the corresponding Wikipedia page is updated as soon as the actual event happened (Becker 2012.

  • Modeling Popularity and Reliability of Sources in Multilingual Wikipedia
    information Article Modeling Popularity and Reliability of Sources in Multilingual Wikipedia Włodzimierz Lewoniewski * , Krzysztof W˛ecel and Witold Abramowicz Department of Information Systems, Pozna´nUniversity of Economics and Business, 61-875 Pozna´n,Poland; [email protected] (K.W.); [email protected] (W.A.) * Correspondence: [email protected] Received: 31 March 2020; Accepted: 7 May 2020; Published: 13 May 2020 Abstract: One of the most important factors impacting quality of content in Wikipedia is presence of reliable sources. By following references, readers can verify facts or find more details about described topic. A Wikipedia article can be edited independently in any of over 300 languages, even by anonymous users, therefore information about the same topic may be inconsistent. This also applies to use of references in different language versions of a particular article, so the same statement can have different sources. In this paper we analyzed over 40 million articles from the 55 most developed language versions of Wikipedia to extract information about over 200 million references and find the most popular and reliable sources. We presented 10 models for the assessment of the popularity and reliability of the sources based on analysis of meta information about the references in Wikipedia articles, page views and authors of the articles. Using DBpedia and Wikidata we automatically identified the alignment of the sources to a specific domain. Additionally, we analyzed the changes of popularity and reliability in time and identified growth leaders in each of the considered months. The results can be used for quality improvements of the content in different languages versions of Wikipedia.

Collective Intelligence and Neutral Point of View: The Case of Wikipedia Shane Greenstein and Feng Zhu NBER Working Paper No. 18167 June 2012 JEL No. L17,L3,L86 ABSTRACT We examine whether collective intelligence helps achieve a neutral point of view using data from a decade of Wikipedia’s articles on US politics. Our null hypothesis builds on Linus’ Law, often expressed as “Given enough eyeballs, all bugs are shallow.” Our findings are consistent with a narrow interpretation of Linus’ Law, namely, a greater number of contributors to an article makes an article more neutral. No evidence supports a broad interpretation of Linus’ Law. Moreover, several empirical facts suggest the law does not shape many articles. The majority of articles receive little attention, and most articles change only mildly from their initial slant.

  • A Natural Experiment at Chinese Wikipedia
    American Economic Review 101 (June 2011): 1601–1615 http://www.aeaweb.org/articles.php?doi 10.1257/aer.101.4.1601 = Group Size and Incentives to Contribute: A Natural Experiment at Chinese Wikipedia By Xiaoquan Michael Zhang and Feng Zhu* ( ) Many public goods on the Internet today rely entirely on free user contributions. Popular examples include open source software development communities e.g., ( Linux, Apache , open content production e.g., Wikipedia, OpenCourseWare , and ) ( ) content sharing networks e.g., Flickr, YouTube . Several studies have examined the ( ) incentives that motivate these free contributors e.g., Josh Lerner and Jean Tirole ( 2002; Karim R. Lakhani and Eric von Hippel 2003 . ) In this paper, we examine the causal relationship between group size and incen- tives to contribute in the setting of Chinese Wikipedia, the Chinese language ver- sion of an online encyclopedia that relies entirely on voluntary contributions. The group at Chinese Wikipedia is composed of Chinese-speaking people in mainland China, Taiwan, Hong Kong, Singapore, and other regions in the world, who are aware of Chinese Wikipedia and have access to it. Our identification hinges on the exogenous reduction in group size at Chinese Wikipedia as a result of the block of Chinese Wikipedia in mainland China in October 2005. During the block, mainland Chinese could not use or contribute to Chinese Wikipedia, although contributors outside mainland China could continue to do so. We find that contribution levels of these nonblocked contributors decrease by 42.8 percent on average as a result of the block. We attribute the cause to social effects: contributors receive social benefits from their contributions, and the shrinking group size reduces these social benefits.

  • The Copycat of Wikipedia in China
    The Copycat of Wikipedia in China Gehao Zhang COPYCATS OFWIKIPEDIA Wikipedia, an online project operated by ordinary people rather than professionals, is often considered a perfect example of human collaboration. Some researchers ap- plaud Wikipedia as one of the few examples of nonmarket peer production in an overwhelmingly corporate ecosystem.1 Some praise it as a kind of democratization of information2 and even call it a type of revolution.3 On the other hand, some researchers worry about the dynamics and consequences of conflicts4 in Wikipedia. However, all of these researchers have only analyzed the original and most well- known Wikipedia—the English Wikipedia. Instead, this chapter will provide a story from another perspective: the copycat of Wikipedia in China. These copycats imitate almost every feature of Wikipedia from the website layout to the core codes. Even their names are the Chinese equivalent of Pedia. With the understanding of Wiki- pedia’s counterpart we can enhance our sociotechnical understanding of Wikipedia from a different angle. Wikipedia is considered an ideal example of digital commons: volunteers gener- ate content in a repository of knowledge. Nevertheless, this mode of knowledge production could also be used as social factory,5, 6 and user-generated content may be taken by commercial companies, like other social media. The digital labor and overture work of the volunteers might be exploited without payment. Subsequently, the covert censorship and surveillance system behind the curtain can also mislead the public’s understanding of the content. In this sense, the Chinese copycats of Wiki- pedia provide an extreme example. This chapter focuses on how Chinese copycats of Wikipedia worked as a so-called social factory to pursue commercial profits from volunteers’ labor.

  • Wikipedia Matters∗
    Wikipedia Matters∗ Marit Hinnosaar† Toomas Hinnosaar‡ Michael Kummer§ Olga Slivko¶ September 29, 2017 Abstract We document a causal impact of online user-generated information on real-world economic outcomes. In particular, we conduct a randomized field experiment to test whether additional content on Wikipedia pages about cities affects tourists’ choices of overnight visits. Our treatment of adding information to Wikipedia increases overnight visits by 9% during the tourist season. The impact comes mostly from improving the shorter and incomplete pages on Wikipedia. These findings highlight the value of content in digital public goods for informing individual choices. JEL: C93, H41, L17, L82, L83, L86 Keywords: field experiment, user-generated content, Wikipedia, tourism industry 1 Introduction Asymmetric information can hinder efficient economic activity. In recent decades, the Internet and new media have enabled greater access to information than ever before. However, the digital divide, language barriers, Internet censorship, and technological con- straints still create inequalities in the amount of accessible information. How much does it matter for economic outcomes? In this paper, we analyze the causal impact of online information on real-world eco- nomic outcomes. In particular, we measure the impact of information on one of the primary economic decisions—consumption. As the source of information, we focus on Wikipedia. It is one of the most important online sources of reference.

  • Visual Narratives and Collective Memory Across Peer-Produced Accounts of Contested Sociopolitical Events
    XX Visual Narratives and Collective Memory across Peer-Produced Accounts of Contested Sociopolitical Events EMILY PORTER, University of Washington, USA P.M. KRAFFT∗, University of Oxford, UK BRIAN KEEGAN, University of Colorado, USA Studying cultural variation in recollections of sociopolitical events is crucial for achieving diverse understand- ings of such events. To date, most studies in this area have focused on analyzing variation in texts describing events. Here we analyze variation in image usage across Wikipedia language editions to understand if like text, visual narratives reflect distinct perspectives in articles about culturally-tethered events. We focus on articles about coup d’états as an example of highly contextual sociopolitical events likely to display such variation. The key challenge to examining variation in images is that there is no existing framework to use as a basis for comparison. To address this challenge, we use an iterative inductive coding process to arrive at a 46-item typology for categorizing the content of images relating to contested sociopolitical events, and a typology of network motifs that characterizes structural patterns of image use. We apply these typologies in a large-scale quantitative analysis that establishes clusters of image themes, two detailed qualitative case studies comparing Wikipedia articles on coup d’états in Soviet Russia and Egypt, and four quantitative analyses clustering image themes by language usage at the article level. These analyses document variation in imagery around particular events and variation in tendencies across cultures. We find substantial cultural variation in both content and network structure. This study presents a novel methodological framework for uncovering culturally divergent perspective of political crises through imagery on Wikipedia.
