4€€€€An Encyclopedia with Breaking News
Wikipedia @ 20 • ::Wikipedia @ 20 4 An Encyclopedia with Breaking News Brian Keegan Published on: Oct 15, 2020 Updated on: Nov 16, 2020 License: Creative Commons Attribution 4.0 International License (CC-BY 4.0) Wikipedia @ 20 • ::Wikipedia @ 20 4 An Encyclopedia with Breaking News Wikipedia’s response to the September 11 attacks profoundly shaped its rules and identity and illuminated a new strategy for growing the project by coupling the supply and demand for information about news. Wikipedia’s breaking news collaborations offer lessons for hardening other online platforms against polarization, disinformation, and other sociotechnical sludge. The web was a very different place for news in the United States between 2001 and 2006. The hanging chads from the 2000 presidential election, the spectacular calamity of 9/11, the unrepentant lies around Operation Iraqi Freedom, and the campy reality television featuring Donald Trump were all from this time. The burst of the dot-com bubble and corporate malfeasance of companies like Enron dampened entrepreneurial spirits, news publishers were optimistically sharing their stories online without paywalls, and blogging was heralded as the future of technology-mediated accountability and participatory democracy. “You” was Time Magazine’s Person of the Year in 2006 because “Web 2.0” platforms like YouTube, MySpace, and Second Life had become tools for “bringing together the small contributions of millions of people and making them matter.”1 Wikipedia was a part of this primordial soup, predating news-feed-mediated engagement, recommender-driven polarization, politicized content moderation, and geopolitical disinformation campaigns. From very early in its history, Wikipedia leveraged the supply and demand for information about breaking news and current events into strategies that continue to sustain this radical experiment in online peer production. -
To Make Claims About Or Even Adequately Understand the "True Nature" of Organizations Or Leadership Is a Monumental Task
BooK REvrnw: HERE CoMES EVERYBODY: THE PowER OF ORGANIZING WITHOUT ORGANIZATIONS (Clay Shirky, Penguin Press, 2008. Hardback, $25.95] -CHRIS FRANCOVICH GONZAGA UNIVERSITY To make claims about or even adequately understand the "true nature" of organizations or leadership is a monumental task. To peer into the nature of the future of these complex phenomena is an even more daunting project. In this book, however, I think we have both a plausible interpretation of organ ization ( and by implication leadership) and a rare glimpse into what we are becoming by virtue of our information technology. We live in a complex, dynamic, and contingent environment whose very nature makes attributing cause and effect, meaning, or even useful generalizations very difficult. It is probably not too much to say that historically the ability to both access and frame information was held by the relatively few in a system and structure whose evolution is, in its own right, a compelling story. Clay Shirky is in the enviable position of inhabiting the domain of the technological elite, as well as being a participant and a pioneer in the social revolution that is occurring partly because of the technologies and tools invented by that elite. As information, communication, and organization have grown in scale, many of our scientific, administrative, and "leader-like" responses unfortu nately have remained the same. We find an analogous lack of appropriate response in many followers as evidenced by large group effects manifested through, for example, the response to advertising. However, even that herd like consumer behavior seems to be changing. Markets in every domain are fragmenting. -
Modeling and Analyzing Latency in the Memcached System
Modeling and Analyzing Latency in the Memcached system Wenxue Cheng1, Fengyuan Ren1, Wanchun Jiang2, Tong Zhang1 1Tsinghua National Laboratory for Information Science and Technology, Beijing, China 1Department of Computer Science and Technology, Tsinghua University, Beijing, China 2School of Information Science and Engineering, Central South University, Changsha, China March 27, 2017 abstract Memcached is a widely used in-memory caching solution in large-scale searching scenarios. The most pivotal performance metric in Memcached is latency, which is affected by various factors including the workload pattern, the service rate, the unbalanced load distribution and the cache miss ratio. To quantitate the impact of each factor on latency, we establish a theoretical model for the Memcached system. Specially, we formulate the unbalanced load distribution among Memcached servers by a set of probabilities, capture the burst and concurrent key arrivals at Memcached servers in form of batching blocks, and add a cache miss processing stage. Based on this model, algebraic derivations are conducted to estimate latency in Memcached. The latency estimation is validated by intensive experiments. Moreover, we obtain a quantitative understanding of how much improvement of latency performance can be achieved by optimizing each factor and provide several useful recommendations to optimal latency in Memcached. Keywords Memcached, Latency, Modeling, Quantitative Analysis 1 Introduction Memcached [1] has been adopted in many large-scale websites, including Facebook, LiveJournal, Wikipedia, Flickr, Twitter and Youtube. In Memcached, a web request will generate hundreds of Memcached keys that will be further processed in the memory of parallel Memcached servers. With this parallel in-memory processing method, Memcached can extensively speed up and scale up searching applications [2]. -

Being the second workshop on this topic, we were able to build on the success of the previous workshop on this topic held as part of ACL-IJCNLP 2009. In many works, collaboratively constructed semantic resources have been used to overcome the knowledge acquisition bottleneck and coverage problems pertinent to conventional lexical semantic resources. The greatest popularity in this respect can so far certainly be attributed to Wikipedia. However, other resources, such as folksonomies or the multilingual collaboratively constructed dictionary Wiktionary, have also shown great potential. Thus, the scope of the workshop deliberately includes any collaboratively constructed resource, not only Wikipedia. Effective deployment of such resources to enhance Natural Language Processing introduces a pressing need to address a set of fundamental challenges, e.g. the interoperability with existing resources, or the quality of the extracted lexical semantic knowledge. Interoperability between resources is crucial as no single resource provides perfect coverage. -

This experiment was designed to explore how knowledge is created and represented on Wikipedia, by working to improve a single article. The overall objective of the class was to give students an understanding of how historians can create “signal” in the “noise” of the Internet and how historians create knowledge using digital media tools. Given that doing “research” online often involves selecting a resource suggested by Google (generally one within the first three to five results),1 this class had larger media literacy goals as well. The students were drawn from all areas of the university, with the only stipulation being that they had to be in their first year. The positive feedback loops inherent in the World Wide Web’s struc- ture greatly influence the way history is consumed, disseminated, and cre- ated online. Google’s algorithms will retrieve an article from Wikipedia, typically displaying it as one of the first links on the results page. Some- one somewhere will decide that the information is “wrong,” and he (it is typically a he)2 will “fix” the information, clicking on the “edit” button to make the change. -
Using Wikipedia to Strengthen Research and Critical Thinking Skills
From Audience to Authorship to Authority: Using Wikipedia to Strengthen Research and Critical Thinking Skills Michele Van Hoeck and Debra Hoffmann This paper looks at Wikipedia’s effectiveness as a pedagogical tool to encourage students to think critical- ly about notions of audience, authorship and authority, and also Wikipedia’s impact on student research persistence. Two case studies are presented in which Wikipedia was used as the platform for assignments in 1) a two-unit freshman information literacy course at California State University (CSU), Maritime (Cal Maritime), and 2) in two three-unit, cross-listed upper-division courses at CSU Channel Islands (CI). At Cal Maritime, the course culminated with students significantly expanding a Wikipedia article. At CI, one course used Wikipedia to explore issues of authority and expertise; the other course used Wikipedia to think critically about notions of authorship and audience. Cal Maritime data on student attitudes, re- search practices such as interlibrary loan borrowing, and student citations suggest the Wikipedia plat- form had, overall, a positive impact on research persistence. Finally, the authors discuss lessons learned from initial use of Wikipedia in the classroom and opportunities for instruction librarians to incorporate Wikipedia into information literacy instruction outside of a credit-bearing course. Introduction and critical thinking skills as editors and creators of Information Literacy instruction often focuses on content. We take a case study approach in presenting cautioning students regarding the use of Wikipedia experiences on two California State University cam- as a credible source for their research, as authors of puses in which Wikipedia was used as the platform Wikipedia articles are often anonymous, and edit- for assignments in credit-bearing information literacy ing Wikipedia does not require proof of expertise. -
Program Statistics
AN INTENSIVE, 4-WEEK ONLINE WORKSHOP DESIGNED TO ACCELERATE LEADERS WHO ARE CHANGE AGENTS FOR THE FUTURE. PROGRAM STATISTICS Only 2% of the enrolled students in Massive Online Courses complete the course. Smaller courses have a much better completion rate, but even the best typically lose half their students. More than 97% of each class of the altMBA successfully complete our 4 week intensive workshop. And every single one reports that the workshop exceeded their expectations, that it was the most intense and productive online engagement that they’ve ever experienced. The altMBA is now enrolling students for its fifth session. We’ve learned a lot from the hundreds of students who have trusted themselves enough to level up with us. About half of our students are rising managers and executives, many at well-known companies like Whole Foods, Lululemon and Microsoft. They’re finding an entirely new frontier, a place to discover skills that they didn’t know they had. This is where they leap from being employees to leaders. About a third of our students are founders, executives and successful freelancers. They’re used to being in charge but they’re not always practiced at being able to see what’s available, at being able to describe a future they are capable of creating. And the rest of our students are non-profit executives, explorers and ruckus makers. These brave souls are eager to engage with the possible, to explore avenues that don’t feel comfortable or easy, but turn out to be quite important. At our most recent Leadership Workshop, attendees came from 19 different time zones. -

Web edition, Copyright © 2011 by Joseph Michael Reagle Jr. CC-NC-SA 3.0 Purchase at Amazon.com | Barnes and Noble | IndieBound | MIT Press Wikipedia's style of collaborative production has been lauded, lambasted, and satirized. Despite unease over its implications for the character (and quality) of knowledge, Wikipedia has brought us closer than ever to a realization of the centuries-old Author Bio & Research Blog pursuit of a universal encyclopedia. Good Faith Collaboration: The Culture of Wikipedia is a rich ethnographic portrayal of Wikipedia's historical roots, collaborative culture, and much debated legacy.

Crowdsourcing Metadata for Library and Museum Collections Using a Taxonomy of Flickr User Behavior
CROWDSOURCING METADATA FOR LIBRARY AND MUSEUM COLLECTIONS USING A TAXONOMY OF FLICKR USER BEHAVIOR A Thesis Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Master of Science by Evan Fay Earle January 2014 © 2014 Evan Fay Earle ABSTRACT Library and museum staff members are faced with having to create descriptions for large numbers of items found within collections. Immense collections and a shortage of staff time prevent the description of collections using metadata at the item level. Large collections of photographs may contain great scholarly and research value, but this information may only be found if items are described in detail. Without detailed descriptions, the items are much harder to find using standard web search techniques, which have become the norm for searching library and museum collection catalogs. To assist with metadata creation, institutions can attempt to reach out to the public and crowdsource descriptions. An example of crowdsourced description generation is the website, Flickr, where the entire user community can comment and add metadata information in the forms of tags to other users’ images. This paper discusses some of the problems with metadata creation and provides insight on ways in which crowdsourcing can benefit institutions. Through an analysis of tags and comments found on Flickr, behaviors are categorized to show a taxonomy of users. This information is used in conjunction with survey data in an effort to show if certain types of users have characteristics that are most beneficial to enhancing metadata in existing library and museum collections. -

Jaron Lanier: 'The Solution Is to Double Down on Being Human'
Jaron Lanier: ‘The solution is to double down on being human’ Tim Adams Last modified on Saturday 2 December 2017 16.41 GMT ‘I think virtual reality will become a proper medium of artʼ: Jaron Lanier at home in California, with some of his 1,000 musical instruments. Photograph: Saroyan Humphrey Jaron Lanier has written a book about virtual reality, a phrase he coined and a concept he did much to invent. It has the heady title Dawn of the New Everything. But it’s also a tale of his growing up and when you read it, what you really want to talk to him about is parenting. Lanier is 57, but his childhood as he describes it was so sad and so creative and so extreme, it makes him almost seem fated to pursue alternative worlds. Lanier’s parents met in New York. His mother, Lilly, blond and light- skinned and Jewish, had somehow talked her way out of a “pop-up concentration camp” in Vienna after the Anschluss, aged 15. The family of his father, Ellery, had escaped a murderous pogrom in Ukraine. They met as part of a circle of artists in Greenwich Village in the 1950s. Lilly was a painter and a dancer, Ellery an architect, but when Jaron was born in 1960 they moved to El Paso, Texas, right on the border with Mexico. Lanier was never sure why, but he believes it was an effort, given their own childhoods, to “live as obscurely as possible”, off grid. His mother did not trust American schooling, so he went across the border to a Montessori school in Mexico each day; then, after a change of heart, to a Texas public high school, where he was bullied.
