Visualizing the inner lives of texts BIBAFull-TextPDF 1
  Fernanda Viégas; Martin Wattenberg
Visualization is often viewed as a way to unlock the secrets of numeric data. But what about political speeches, novels, and blogs? These texts hold at least as many surprises. On the Many Eyes site, a place for collective visualization, we have seen an increasing appetite for analyzing documents. We present a series of techniques for visualizing and analyzing unstructured text. We also discuss how a technique developed for visualizing the authoring patterns of Wikipedia articles has recently revealed the collective lives of a much broader class of documents.

Community performance optimization: making your people run as smoothly as your site BIBAFull-TextPDF 2
  Brion Vibber
Collaborative communities such as those building wikis and open source software often discover that their human interactions have just as many scaling problems as their web infrastructure. As the number of people involved in a project grows, key decision-makers often become bottlenecks, and community structure needs to change or a project can become stalled despite the best intentions of all participants. I'll describe some of the community scaling challenges in both Wikipedia's editor community and the development of its underlying MediaWiki software and how we've overcome -- or are still working to overcome -- decision-making bottlenecks to "maximize community throughput".

Understanding learning: the Wiki way BIBAKFull-TextPDF 3
  Joachim Kimmerle; Johannes Moskaliuk; Ulrike Cress
Learning "the wiki way", learning through wikis is a form of self-regulated learning that is independent of formal learning settings and takes place in a community of knowledge. Such a community may work jointly on a digital artifact to create new, innovative and emergent knowledge. We regard wikis as a prototype of tools for community-based learning, and point out five relevant features. We will present the co-evolution model, as introduced by Cress and Kimmerle [3][4], that may be understood as a framework to describe learning in the wiki way. This model describes collaborative knowledge building as a co-evolution between cognitive and social systems. To investigate learning the wiki way, we have to consider both individual processes and processes within the wiki, which represent the processes that are going on within a community.
   This paper presents three empirical studies that investigate learning the wiki way in a laboratory setting. We take a look at participants' contributions to a wiki indicating processes within the wiki community, and measure the extent of individual learning at the end of the experiment. Our conclusion is that the model of co-evolution has a strong impact on understanding learning the wiki way, may be helpful to designers of learning environments, and serve as framework for further research.

rv you're dumb: identifying discarded work in Wiki article history BIBAKFull-TextPDF 4
  Michael D. Ekstrand; John T. Riedl
Wiki systems typically display article history as a linear sequence of revisions in chronological order. This representation hides deeper relationships among the revisions, such as which earlier revision provided most of the content for a later revision, or when a revision effectively reverses the changes made by a prior revision. These relationships are valuable in understanding what happened between editors in conflict over article content. We present methods for detecting when a revision discards the work of one or more other revisions, a means of visualizing these relationships in-line with existing history views, and a computational method for detecting discarded work. We show through a series of examples that these tools can aid mediators of wiki content disputes by making salient the structure of the ongoing conflict. Further, the computational tools provide a means of determining whether or not a revision has been accepted by the community of editors surrounding the article.

Bipartite networks of Wikipedia's articles and authors: a meso-level approach BIBAKFull-TextPDF 5
  Rut Jesus; Martin Schwartz; Sune Lehmann
This exploratory study investigates the bipartite network of articles linked by common editors in Wikipedia, 'The Free Encyclopedia that Anyone Can Edit'. We use the articles in the categories (to depth three) of Physics and Philosophy and extract and focus on significant editors (at least 7 or 10 edits per each article). We construct a bipartite network, and from it, overlapping cliques of densely connected articles and editors. We cluster these densely connected cliques into larger modules to study examples of larger groups that display how volunteer editors flock around articles driven by interest, real-world controversies, or the result of coordination in WikiProjects. Our results confirm that topics aggregate editors; and show that highly coordinated efforts result in dense clusters.

SAVVY Wiki: a context-oriented collaborative knowledge management system BIBAKFull-TextPDF 6
  Takafumi Nakanishi; Koji Zettsu; Yutaka Kidawara; Yasushi Kiyoki
This paper presents a new Wiki called SAVVY Wiki that realizes context-oriented, collective and collaborative knowledge management environments that are able to reflect users' intentions and recognitions. Users can collaboratively organize fragmentary knowledge with the help of the SAVVY Wiki. Fragmentary knowledge, in this case, implies existing Wiki content, multimedia content on the web, and so on. Users select and allocate fragmentary knowledge in different contexts onto the SAVVY Wiki. Owing to this operation, it is ensured that related pages belong to the same contexts. That is, users can find correlations among the pages in a Wiki. The SAVVY Wiki provides new collective knowledge created from fragmentary knowledge, depending on contexts, in accordance with the users' collaborative operations. Various collaborative working environments have been developed for the sharing of collective knowledge. Most current Wikis have a collaborative editing mode to every page, as a platform to enable a collaborative working environment. In order to understand an arbitrary concept thoroughly, it is necessary to find correlations among the various threads of content, depending on the users' purpose, task or interest. In a Wiki system, it is important to realize a collaborative editing environment with correlation among pages depending on the contexts. In this paper, we present a method to realize the SAVVY Wiki, and describe its developing prototype system.

Herding the cats: the influence of groups in coordinating peer production BIBAKFull-TextPDF 7
  Aniket Kittur; Bryan Pendleton; Robert E. Kraut
Peer production systems rely on users to self-select appropriate tasks and "scratch their personal itch". However, many such systems require significant maintenance work, which also implies the need for collective action, that is, individuals following goals set by the group and performing good citizenship behaviors. How can this paradox be resolved? Here we examine one potential answer: the influence of social identification with the larger group on contributors' behavior. We examine Wikipedia, a highly successful peer production system, and find a significant and growing influence of group structure, with a prevalent example being the WikiProject. Comparison of editors who join projects with those who do not and comparisons of the joiners' behavior before and after they join a project suggest their identification with the group plays an important role in directing them towards group goals and good citizenship behaviors. Upon joining, Wikipedians are more likely to work on project-related content, to shift their contributions towards coordination rather than production work, and to perform maintenance work such as reverting vandalism. These results suggest that group influence can play an important role in maintaining the health of online communities, even when such communities are putatively self-directed peer production systems.

The singularity is not near: slowing growth of Wikipedia BIBAKFull-TextPDF 8
  Bongwon Suh; Gregorio Convertino; Ed H. Chi; Peter Pirolli
Prior research on Wikipedia has characterized the growth in content and editors as being fundamentally exponential in nature, extrapolating current trends into the future. We show that recent editing activity suggests that Wikipedia growth has slowed, and perhaps plateaued, indicating that it may have come against its limits to growth. We measure growth, population shifts, and patterns of editor and administrator activities, contrasting these against past results where possible. Both the rate of page growth and editor growth has declined. As growth has declined, there are indicators of increased coordination and overhead costs, exclusion of newcomers, and resistance to new edits. We discuss some possible explanations for these new developments in Wikipedia including decreased opportunities for sharing existing knowledge and increased bureaucratic stress on the socio-technical system itself.

Lively Wiki a development environment for creating and sharing active web content BIBAKFull-TextPDF 9
  Robert Krahn; Dan Ingalls; Robert Hirschfeld; Jens Lincke; Krzysztof Palacz
Wikis are Web-based collaborative systems designed to help people share information. Wikis have become popular due to their openness which gives users complete control over the organization and the content of wiki pages. Unfortunately existing wiki engines restrict users to enter only passive content, such as text, graphics, and videos and do not allow users to customize wiki pages. Thus, wikis cannot be used to host or author rich dynamic and interactive content. In this paper we present Lively Wiki, a development and collaboration environment based on the Lively Kernel which enables users to create rich and interactive Web pages and applications -- without leaving the Web. Lively Wiki combines the wiki metaphor with a direct-manipulation user interface and adds a concept for Web programming as well as programming tool support to create an easy to use, scalable, and extendable Web authoring tool. Moreover, Lively Wiki is self-supporting, i.e. the development tools were used for creating its own implementation thereby giving users the freedom to customize every aspect of the system.

Adessowiki on-line collaborative scientific programming platform BIBAKFull-TextPDF 10
  Roberto A. Lotufo; Rubens C. Machado; André Körbes; Rafael G. Ramos
Adessowiki (http://www.adessowiki.org) is a collaborative environment for development, documentation, teaching and knowledge repository of scientific computing algorithms. The system is composed of a collection of collaborative web pages in the form of a wiki. The articles of this wiki can embed programming code that will be executed on the server when the page is rendered, incorporating the results as figures, texts and tables on the document. The execution of code at the server allows hardware and software centralization and access through a web browser. This combination of a collaborative wiki environment, central server and execution of code at rendering time enables a host of possible applications like, for example: a teaching environment, where students submit their reports and exercises on Adessowiki without needing to install special software; authoring of texts, papers and scientific computing books, where figures are generated in a reproducible way by programs written by the authors; comparison of solutions and benchmarking of algorithms given that all the programs are executed under the same configuration; creation of an encyclopedia of algorithms and executable source code. Adessowiki is an environment that carries simultaneously documentation, programming code and results of its execution without any software configuration such as compilers, libraries and special tools at the client side.

Measuring the wikisphere BIBAKFull-TextPDF 11
  Jeff Stuckman; James Purtilo
Due to the inherent difficulty in obtaining experimental data from wikis, past quantitative wiki research has largely been focused on Wikipedia, limiting the degree that it can be generalized. We developed WikiCrawler, a tool that automatically downloads and analyzes wikis, and studied 151 popular wikis running Mediawiki (none of them Wikipedias). We found that our studied wikis displayed signs of collaborative authorship, validating them as objects of study. We also discovered that, as in Wikipedia, the relative contribution levels of users in the studied wikis were highly unequal, with a small number of users contributing a disproportionate amount of work. In addition, power-law distributions were successfully fitted to the contribution levels of most of the studied wikis, and the parameters of the fitted distributions largely predicted the high inequality that was found. Along with demonstrating our methodology of analyzing wikis from diverse sources, the discovered similarities between wikis suggest that most wikis accumulate edits through a similar underlying mechanism, which could motivate a model of user activity that is applicable to wikis in general.

An architecture to support intelligent user interfaces for Wikis by means of Natural Language Processing BIBAKFull-TextPDF 12
  Johannes Hoffart; Torsten Zesch; Iryna Gurevych
We present an architecture for integrating a set of Natural Language Processing (NLP) techniques with a wiki platform. This entails support for adding, organizing, and finding content in the wiki. We perform a comprehensive analysis of how NLP techniques can support the user interaction with the wiki, using an intelligent interface to provide suggestions. The architecture is designed to be deployed with any existing wiki platform, especially those used in corporate environments. We implemented a prototype integrating the NLP techniques keyphrase extraction and text segmentation, as well as an improved search engine. The prototype is integrated with two widely used wiki platforms: Media-Wiki and TWiki.

Social search and need-driven knowledge sharing in Wikis with Woogle BIBAKFull-TextPDF 13
  Hans-Jörg Happel
Wikis have emerged as easy and flexible tools for accessing and sharing knowledge on the internet and within organizations. Due to their highly collaborative nature, users can typically modify and create content without any access restrictions since these are replaced by social practices. On the other hand, due to the lack of central guidance, knowledge sharing is driven by the individual choice of contributors. We claim that -- especially in enterprise settings -- the lack of guidance for content creation is a major problem. We therefore analyze search and knowledge sharing in current Wikis. To improve knowledge sharing, we present the Woogle concept, which introduces "Social Search" and "Need-driven Knowledge Sharing" into Wikis. We describe our prototype implementation Woogle4MediaWiki and results from initial evaluation studies.
Keywords: Wikis, knowledge sharing, social search
Wikibugs: using template messages in open content collections BIBAKFull-TextPDF 14
  Loris Gaio; Matthijs den Besten; Alessandro Rossi; Jean-Michel Dalle
In the paper we investigate an organizational practice meant to increase the quality of commons-based peer production: the use of template messages in wiki-collections to highlight editorial bugs and call for intervention. In the context of SimpleWiki, an online encyclopedia of the Wikipedia family, we focus on {complex}, a template which is used to flag articles disregarding the overall goals of simplicity and readability. We characterize how this template is placed on and removed from articles and we use survival analysis to study the emergence and successful treatment of these bugs in the collection.

A jury of your peers: quality, experience and ownership in Wikipedia BIBAKFull-TextPDF 15
  Aaron Halfaker; Aniket Kittur; Robert Kraut; John Riedl
Wikipedia is a highly successful example of what mass collaboration in an informal peer review system can accomplish. In this paper, we examine the role that the quality of the contributions, the experience of the contributors and the ownership of the content play in the decisions over which contributions become part of Wikipedia and which ones are rejected by the community. We introduce and justify a versatile metric for automatically measuring the quality of a contribution. We find little evidence that experience helps contributors avoid rejection. In fact, as they gain experience, contributors are even more likely to have their work rejected. We also find strong evidence of ownership behaviors in practice despite the fact that ownership of content is discouraged within Wikipedia.

Assessing the quality of Wikipedia articles with lifecycle based metrics BIBAKFull-TextPDF 16
  Thomas Wöhner; Ralf Peters
The main feature of the free online-encyclopedia Wikipedia is the wiki-tool, which allows viewers to edit the articles directly in the web browser. As a weakness of this openness for example the possibility of manipulation and vandalism cannot be ruled out, so that the quality of any given Wikipedia article is not guaranteed. Hence the automatic quality assessment has been becoming a high active research field. In this paper we offer new metrics for an efficient quality measurement. The metrics are based on the lifecycles of low and high quality articles, which refer to the changes of the persistent and transient contributions throughout the entire life span.

Wiki credibility enhancement BIBAKFull-TextPDF 17
  Felix Halim; Wu Yongzheng; Roland Yap
Wikipedia has been very successful as an open encyclopedia which is editable by anybody. However, the anonymous nature of Wikipedia means that readers may have less trust since there is no way of verifying the credibility of the authors or contributors. We propose to automatically transfer external information about the authors from outside Wikipedia to Wikipedia pages. This additional information is meant to enhance the credibility of the content. For example, it could be the education level, professional expertise or affiliation of the author. We do this while maintaining anonymity. In this paper, we present the design and architecture of such system together with a prototype.

Organizing the vision for web 2.0: a study of the evolution of the concept in Wikipedia BIBAKFull-TextPDF 18
  Arnaud Gorgeon; E. Burton Swanson
Information Systems (IS) innovations are often characterized by buzzwords, reflecting organizing visions that structure and express the images and ideas formed by a wide community of users about their meaning and purpose. In this paper, we examine the evolution of Web 2.0, a buzzword that is now part of the discourse of a broad community, and look at its entry in Wikipedia over the three years since its inception in March 2005. We imported the revision history from Wikipedia, and analyzed and categorized the edits that were performed and the users that contributed to the article. The patterns of evolution of the types and numbers of contributors and edits lead us to propose four major periods in the evolution of the Web 2.0 article: Seeding, Germination, Growth and Maturity. During the Seeding period, the article evolved mostly underground, with few edits and few contributors active. The article growth took off during the Germination period, receiving increasing attention. Growth was the most active period of development, but also the most controversial. During the last period, Maturity, the article received a decreasing level of attention, current and potential contributors losing interest, as a consensus about what the concept of Web 2.0 means seemed to have been reached.

Experience report -- Wiki for law firms BIBAFull-TextPDF 19
  Urs Egli; Peter Sommerlad
This paper shows the experiences of a law firm with adopting Wiki Webs for knowledge management and collaboration over the last two years. Wikis created a business advantage for the lawyers through better re-use of their know-how within the firm. In addition, external Wikis for clients created new revenue opportunities and higher client satisfaction. The law firm uses a very simple Wiki implementation that makes it very easy to establish new Wiki instances. For client collaboration the Wiki was secured and extended with a simple user management system.
knowIT, a semantic informatics knowledge management system BIBAKFull-TextPDF 20
  Laurent Alquier; Keith McCormick; Ed Jaeger
We present knowIT, a collaborative database designed to manage the shared knowledge about Informatics Systems in a research organization. In this paper, we discuss requirements that emerged through years of use and we describe the challenges of migrating content from an existing relational database to a solution based on a Semantic MediaWiki. Finally, we review which customizations were required in order to improve user acceptance, both for editors and viewers. Our experience will serve as a case study for a pragmatic approach to knowledge management.

Visualizing intellectual connections among philosophers using the hyperlink & semantic data from Wikipedia BIBAKFull-TextPDF 21
  Sofia J. Athenikos; Xia Lin
Wikipedia, with its unique structural features and rich user-generated content, is being increasingly recognized as a valuable knowledge source that can be exploited for various applications. The objective of the ongoing project reported in this paper is to create a Web-based knowledge portal for digital humanities based on the data extracted from Wikipedia (and other data sources). In this paper we present the interesting results we have obtained by extracting and visualizing various connections among 300 major philosophers using the structured data available in Wikipedia.

Cosmos: a Wiki data management system BIBAKFull-TextPDF 22
  Qinyi Wu; Calton Pu; Danesh Irani
Wiki applications are becoming increasingly important for knowledge sharing between large numbers of users. To prevent against vandalism and recover from damaging edits, wiki applications need to maintain revision histories of all documents. Due to the large amounts of data and traffic, a Wiki application needs to store the data economically on disk and processes them efficiently. Current wiki data management systems make a trade-off between storage requirement and access time for document update and retrieval. We introduce a new data management system, Cosmos, to balance this trade-off.

WiSyMon: managing systems monitoring information in semantic Wikis BIBAKFull-TextPDF 23
  Frank Kleiner; Andreas Abecker; Sven F. Brinkmann
The work presented in the poster describes our collaborative approach to managing systems monitoring information in a Semantic Wiki. This allows to extend the applicability of managing systems monitoring information from IT personnel to IT-knowledgeable users (e.g., developers, or researchers). Semantic relations edited in the Semantic Wiki are translated into systems monitoring configuration files used by an external application. Information about the status of services and hosts is inserted into the Wiki.

Wikis to support collaborative web spaces to promote youth well-being BIBAFull-TextPDF 24
  Shahper Vodanovich; Max Rohde; Ching-shen Dong; David Sundaram
Youth is a period of rapid emotional, physical and intellectual change, where young people progress from being dependent children to independent adults. Young people who are unable to make this transition smoothly can face significant difficulties in both the short and long term. Although the vast majority of young people are able to find all the resources they need for their health, well-being and development within their families and living environments, some young people have difficulty in locating resources that can help them and, moreover, difficulty in integrating into society. One way to support this transition is to create an environment that enables youth to be well supported through the provision of information and the creation of a community where youth feel empowered to collaborate with their peers as well as decision makers and legislators.
Wikipublisher: a print-on-demand Wiki BIBAKFull-TextPDF 25
  John Rankin; Craig Anslow; James Noble; Brenda Chawner; Donald Gordon
Web and print exist as two solitudes: printed web pages often disappoint and converting print documents into good web pages is hard. A wiki makes it easy for authors to create rich web content, but is little help if readers wish to print the results. Wikipublisher lets readers turn wiki pages or page collections into print, with a quality better than most word processing documents. This lowers the time and cost of creating online and print versions of the same content, with no loss of quality in either medium.

DynaTable: a Wiki extension for structured data BIBAKFull-TextPDF 26
  Carrie Arnold; Todd Fleming; David Largent; Chris Lüer
DynaTable is an extension for the MediaWiki software that provides support for structured data. While tables and lists are popular features in many wikis, they are currently unsupported as first-class entities. As a consequence, creating and editing tables is a manual, error-prone task. DynaTable allows wiki editors to create tables that can be displayed on and transcluded to multiple wiki pages, and can be partially displayed based on different criteria.

Leveraging crowdsourcing heuristics to improve search in Wikipedia BIBAFull-TextPDF 27
  Yasser Ganjisaffar; Sara Javanmardi; Cristina Lopes
Wikipedia articles are usually accompanied with history pages, categories and talk pages. The meta-data available in these pages can be analyzed to gain a better understanding of the content and quality of the articles. We analyze the quality of search results of the current major Web search engines (Google, Yahoo! and Live) in Wikipedia. We discuss how the rich meta-data available in wiki pages can be used to provide better search results in Wikipedia. We investigate the effect of incorporating the extent of review of an article into ranking of search results. The extent of review is measured by the number of distinct editors who have contributed to the articles and is extracted by processing Wikipedia's history pages. Our experimental results show that re-ranking search results of the three major Web search engines, using the review feature, improves quality of their rankings for Wikipedia-specific searches.
Evaluating the trustworthiness of Wikipedia articles through quality and credibility BIBAKFull-TextPDF 28
  Sai T. Moturu; Huan Liu
Wikipedia has become a very popular destination for Web surfers seeking knowledge about a wide variety of subjects. While it contains many helpful articles with accurate information, it also consists of unreliable articles with inaccurate or incomplete information. A casual observer might not be able to differentiate between the good and the bad. In this work, we identify the necessity and challenges for trust assessment in Wikipedia, and propose a framework that can help address these challenges by identifying relevant features and providing empirical means to meet the requirements for such an evaluation. We select relevant variables and perform experiments to evaluate our approach. The results demonstrate promising performance that is better than comparable approaches and could possibly be replicated with other social media applications.

Comparison of middle school, high school and community college students' Wiki activity in Globaloria-West Virginia: (pilot year-two) BIBAKFull-TextPDF 29
  Rebecca Reynolds; Idit Harel Caperton
Constructionist-learning researchers have long emphasized the epistemological value of programming games for learning and cognition. This study reports student experiences in a program of game design and Web 2.0 learning offered to disadvantaged West Virginia middle, high school and community college students. Specifically, the poster presents findings on the extent of student use of the Wiki for project management, teamwork and self-presentation of game design attributes, comparing results across 13 school pilot locations. Also presented are students' self-reported recommendations for possible improvements to the wiki. Results indicate that some locations were more active in their wiki use; the poster addresses location-specific implementation context factors that may have played a role in the variant results.

Incremental knowledge acquisition in software development using a weakly-typed Wiki BIBAKFull-TextPDF 31
  Filipe F. Correia; Hugo S. Ferreira; Nuno Flores; Ademar Aguiar
Software development is a knowledge-intensive activity and frequently implies a progressive crystallization of knowledge, towards programming language statements. Although wikis have proved very effective, for both collaborative authoring and knowledge management, it would be useful for knowledge acquisition to better support team awareness and the recognition of knowledge structures, their relations, and their incremental evolution. This paper presents Weaki, a wiki prototype especially designed to support incremental formalization of structured contents that uses weakly-typed pages and type evolution. Weaki was applied in academic settings, by students of Software Engineering Labs.

Understanding information sharing in software development through Wiki log analysis BIBAKFull-TextPDF 35
  Ammy Jiranida Phuwanartnurak; David G. Hendry
The use of wikis in software development seems to be growing rapidly. Recently, software development teams have begun to employ wikis to do such things as: collaborate across locations; brainstorm and track projects; organize knowledge; and facilitate information sharing. This poster reports preliminary findings from the analysis of the logs of two wikis, which supported two different software development projects. This work shows that, with the wiki log analysis, it is possible to identify patterns of information sharing.

Measuring Wikipedia: a hands-on tutorial BIBAKFull-TextPDF 40
  Luca de Alfaro; Felipe Ortega
This tutorial is an introduction to the best methodologies, tools and practices for Wikipedia research. The tutorial will be led by Luca de Alfaro (Wiki Lab at UCSC, California, USA) and Felipe Ortega (Libresoft, URJC, Madrid, Spain). Both cumulate several years of practical experience exploring and processing Wikipedia data [1], [2], [3]. As well, their respective research groups have led the development of two cutting-edge software tools (WikiTrust and WikiXRay), for analyzing Wikipedia. WikiTrust implements an author reputation system, and a text trust system, for wikis. WikiXRay is a tool automating the quantitative analysis of any language version of Wikipedia (in general, any wiki based on MediaWiki).

Tutorial on agile documentation with Wikis BIBAKFull-TextPDF 41
  Ademar Aguiar
Although some agile projects can succeed without producing any documentation at all, others may require a little more. Best practices of agile documentation suggest producing just enough documentation, at just the right time, and for just the right audience. It is not by coincidence that wikis and agility share goals of simplicity, flexibility, and open collaboration, thus being natural documentation tools to agile projects. When well integrated with other tools, wikis provide open collaboration, quick feedback, easy navigability, integrated contents, and a low barrier for developers to document. In this hands-on tutorial, participants will learn how to adapt and use a wiki to better support software projects.

We demonstrate one of the potential paths of the evolution of wiki engines towards Web 3.0. We introduce 3dWiki -- the 3D wiki engine, which was built according to 2-Layer Interface Paradigm (2LIP). It was developed for use by Copernicus, our vision of a 3D encyclopedia. In the demonstration:
  • We give an overview of 2-Layer Interface Paradigm, an attempt to marry
       advantages of 3D experience with the advantages of narrative structure of
  • We describe step by step how to create an article for Copernicus: from
       creating models for the 3D background, through authoring the content,
       creating the c-links, to publishing the result in our encyclopedia.
  • We show how to use a physics engine in our wiki.
