The Basic Techniques in Text Mining using Open-source Tools

This presentation is part of the WikiSym + OpenSym 2013 program.

Jun Iio

There are many text mining tools provided commercially and non-commercially. However, the elementary text-based analysis can be done with basic Unix commands, shell-scripts, and small program of scripting languages, instead of using such extensive software. This paper introduces the basic techniques for text mining, using combination of a set of standard commands, small code, and generic tools provided as the open-source software. The target of the analysis are sixty-seven articles written by one author in a relay column since 1998. Several text-based analyses reveals a trend of interest moved within about fifteen years. In addition, at the end of this paper, the results of text-based analysis are compared with that of non-text-based analysis and the efficiency of non-parametric analysis is discussed.

Data Twist is a project to help people use Open Data to make directories. It is a project that helps anyone create open versions of Yelp ™ or TripAdvisor ™. Data Twist acts a foundation for open directories by importing OpenStreetMap XML data into WordPress. Data Twist has a few dependencies. One is WordPress. Another is Geo Mashup, a plug-in that allows you to store geo-references with each WordPress post.

Involving users to increase their acceptance

This presentation is part of the WikiSym + OpenSym 2013 program.

Wikipedia is a top-ten web site providing a community-built free encyclopedia. Its success hinges on the support of its volunteer contributors. And Wikipedia is a research object in several academic fields. Wikimedia Deutschland e.V., the German Wikimedia Chapter, is a partner in the EU-funded international research project RENDER – Reflecting knowledge diversity. With this participation we aim to support Wikipedia authors in editing and understanding the status of articles. This experience report focuses on our interaction with in particular the German Wikipedia community less on the project and its results.  We reached members of the Wikipedia community via several ways. In addition to the online channels the live meetings are of particular importance to construct an interested and active community. Additionally, we learned that it is very important to involve the users at an early stage. That helps to increase the acceptance and the willingness to support the project. If Wikipedians can understand a benefit of research results and developments for their daily life in Wikipedia or the advancement for whole project, they will be more willing to give innovations a try.

Empowering formative assessment using embedded Web Widgets in Wikis

This presentation is part of the WikiSym + OpenSym 2013 program.

Michele Notari; Sonja Schär; Martin Schellenberg; Samuel Kai Wah Chu

In this article we describe how we developed and how we use a tool for teachers enhancing inter-group collaboration of learners using wikis in project-based learning settings with over 100 participants, where different groups of students de- velop similar projects and each project has an own wiki page. To achieve our goal we extended typical wiki functionality by using web widgets, mini applications embedded anywhere in the wiki environment using the iframe tag. Two different evaluation widgets (rating widget and ‘working progress‘ widget) are placed on each of the project pages. The project groups use the ‘working progress‘ widget to de- clare the amount of work done. The teacher and the rest of the learning community use the ‘rating‘ widget to rate the ongoing project work. A so called ‘meta widget‘ show- ing a summary of the results of the ‘rating‘ and ‘working progress‘ widget can be displayed on the start page of the learning community or if a project is divided in different milestones, on the page describing the goals and timeline for the milestone. Evaluation widgets and meta widget, which easily can be embedded by the teacher potentially all over the wiki pages, enhances visibility of quality and termina- tion degree of a project and enhance so the self, the tutor and the peer review opportunities in such large scale project based learning settings. The created evaluation widgets and meta widgets have been embedded in the wiki of a three months curriculum. The evaluation of utility and usability of the widgets is ongoing. The educational value of rating and reflecting about the working progress of a given task is discussed.

This study investigates the use of wiki to support project-based learning (PBL) in 3 undergraduate courses of different disciplines: English Language Studies, Information Management, and Mechanical Engineering. This study takes a methodological triangulation approach that employs the use of questionnaires, interviews, and wiki activity logs. The level of activities and the types of core actions captured on wiki varied among the three groups of students. Students generally rated positively on the use of wiki to support PBL, while significant differences were found on 9 items (especially in the “Motivation” and “Knowledge Management” dimensions of the questionnaire) among students in the three different disciplines. Interviews revealed that these differences may be attributable to the variations in the natures and scopes of the PBL, as well as in the different emphases that students placed on the work presented on the wiki. This study may provide directions on the use of wiki in PBL in undergraduate courses.

Descending Mount Everest: Steps towards applied Wikipedia research

This presentation is part of the WikiSym + OpenSym 2013 program.

Dario Taraborelli

Over the last years, Wikipedia has seen an explosion of academic interest, as indicated by a steadily increasing volume of scholarly publications. Due to its history, its size and the immediate availability of its data under open licenses, Wikipedia has served over time as a testbed for sociological and psychological theory; as the primary source of data for models of commons-based peer production and computer-supported collaboration; as a body of norms for research on the governance of online communities; or as a large multilingual corpus to mine, or against which to train text analysis algorithms. This explosion of academic interest reveals a gap between Wikipedia as a topic of scholarly research and Wikipedia as a living community in need of actionable solutions, facing real challenges and the first serious
growth and sustainability problem in its entire lifecycle. The Wikimedia Foundation and the Wikimedia communities have yet to find a viable model to leverage academic expertise to solve these challenges, in the same way that Wikimedia projects have effectively engaged with a large community of contributors and software developers to produce its contents and support its open source infrastructure. In this talk I will review recent research trends spanning scholarly work and internal research conducted at the Wikimedia Foundation, and how these relate to some of the most urgent needs of the Wikimedia movement and the Wikimedia Foundation’s work priorities. I’ll discuss models that can support actionable research, as well as open opportunities for researchers and contributors  to collaborate on developing joint solutions and identifying new growth opportunities for WIkipedia and its communities.

The dual role of conflict in Free and Open Source Software development

This presentation is part of the WikiSym + OpenSym 2013 program.

Anna Filippova

The voluntary and computer mediated nature of FOSS work present challenges to effective collaboration. Conflict within the team is one challenge that may arise due to limited communication channels and the distributed nature of work. As conflict may be both harmful and beneficial for a team, we propose a quantitative content analysis method to identify the various types of conflict that may occur during FOSS development. Additionally, we propose a related study to survey the relationship of these conflict types with FOSS team outputs, in order to better inform community design.

The Dynamics of Gatekeeping in Online Collaborative Systems

This presentation is part of the WikiSym + OpenSym 2013 program.

Bluma S Gelley

In my thesis, I explore the dynamics of gatekeeping in online peer-production communities, such as Wikipedia, Stack Overflow, and various open-source software projects. How are standards set for content inclusion, and what mechanisms are used to find and remove content deemed inappropriate by the community? The subject of vandalism, or the malicious addition of “bad” content, has been widely studied. Here, I focus on content added in good faith that has nevertheless been judged inappropriate for the specific community. I also explore the possibility of using various automated tools to assist humans in gatekeeping tasks.

Wiki Development Environments

This presentation is part of the WikiSym + OpenSym 2013 program.

Christoph Hannebauer

This application to the WikiSym + OpenSym 2013 doctoral symposium describes the current status of the doctoral thesis Wiki Development Environments. The doctoral thesis analyzes contribution barriers to Free, Libre and Open Source Software (FLOSS) projects and how to minimize these contribution barriers. The doctoral thesis contains a novel approach to lower these contribution barriers. This approach comprises the combination of a wiki system and an Integrated Development Environment (IDE) into a Wiki Development Environment (WikiDE). A WikiDE is a web-based code editor that allows anonymous users to edit source code and contribute it to a FLOSS project.
