|Engaging with a wiki related to knowledge translation: A survey of whatiskt wiki users||Mathew D.
|Journal of Medical Internet Research||English||2014||Background: In 2008, WhatisKT wiki was launched as a collaborative platform for knowledge translation (KT) researchers and stakeholders to debate the use and definitions of KT-related terms. The wiki has definitions for over 110 terms from disciplines including health care, information technology, education, accounting, and business. WhatisKT wiki has over 115 registered users. Approximately 73,000 unique visitors have visited the wiki since 2008. Despite annual increases in visitors and regular maintenance of the wiki, no visitors have contributed content or started a discussion. Objective: We surveyed wiki users to gain an understanding of the perceived value of the website, reasons for not engaging in the wiki, and suggestions to facilitate collaboration and improve the usability of the wiki. Methods: We surveyed three cohorts: KT Canada members who were previously invited to join the wiki, registered wiki members, and unregistered visitors. The first two cohorts completed a Web-based survey that included the System Usability Scale (SUS) questionnaire to assess usability; additionally 3 participants were interviewed. Unregistered wiki visitors were surveyed with polls posted on the wiki. The study received ethics approval from the McMaster University Faculty of Health Sciences Research Ethics Board. Results: Twenty-three participants completed the Web-based and SUS surveys; 15 participants indicated that they would collaborate on the wiki. The mean SUS score of 67 (95% CI 56-77) indicated that the wiki could be considered for design improvements. Study participants indicated that the wiki could be improved by email notification regarding new terms, better grouping of terms, user friendly interface, and training for users interested in editing content. Conclusions: The findings from this survey will be used to enhance the design and content of WhatisKT wiki. Further feedback from participants will be used to make the wiki an ideal collaboration platform for KT researchers interested in terminology.||0||0|

SIGA was recently used in Págico, an evaluation contest where both automatic and human participants competed to find answers to 150 topics in the Portuguese Wikipedia, and we describe its new capabilities in this context as well as provide preliminary results from Págico.||0||0|
|Semantic MediaWiki in applied life science and industry: Building an Enterprise Encyclopaedia||Alquier L.||Open Source Software in Life Science Research: Practical Solutions to Common Challenges in the Pharmaceutical Industry and Beyond||English||2012||The popularity of Wikipedia makes it a very enticing model for capturing shared knowledge inside large distributed organisations. However, building an Enterprise Encyclopaedia comes with unique challenges of flexibility, data integration and usability. We propose an approach to overcome these challenges using Semantic MediaWiki, augmenting the mature knowledge sharing capabilities of a wiki with the structure of semantic web principles. We provide simple guidelines to control the scope of the wiki, simplify the users' experiences with capturing their knowledge, and integrate the solution within an enterprise environment. Finally, we illustrate the benefits of this solution with enterprise search and life sciences applications. © 2012 Woodhead Publishing Limited. All rights reserved.||0||0|
|The importance of Human Mental Workload in Web design||Longo L.
|WEBIST 2012 - Proceedings of the 8th International Conference on Web Information Systems and Technologies||English||2012||The focus of this study is the introduction of the construct of Human Mental Workload (HMW) in Web design, aimed at supporting current interaction design practices. An experiment has been conducted using the original Wikipedia and Google web-interfaces, and using two slightly different versions. Three subjective psychological mental workload assessment techniques (NASA-TLX, Workload Profile and SWAT) with a well-established assessments usability tool (SUS) have been adopted. T-tests have been performed to study the statistical significance of the original and modified web-pages, in terms of workload required by typical tasks and perceived usability. Preliminary results show that, in one ideal case, increments of usability correspond to decrements of generated workload, confirming the negative impact of the structural changes on the interface. In another case, changes are significant in terms of usability but not in terms of generated workloads, thus raising research questions and underlying the importance of Human Mental Workload in Interaction Design.||0||0|
|MuZeeker: Adapting a music search engine for mobile phones||Larsen J.E.
|Lecture Notes in Computer Science||English||2010||We describe MuZeeker, a search engine with domain knowledge based on Wikipedia. MuZeeker enables the user to refine a search in multiple steps by means of category selection. In the present version we focus on multimedia search related to music and we present two prototype search applications (web-based and mobile) and discuss the issues involved in adapting the search engine for mobile phones. A category based filtering approach enables the user to refine a search through relevance feedback by category selection instead of typing additional text, which is hypothesized to be an advantage in the mobile MuZeeker application. We report from two usability experiments using the think aloud protocol, in which N=20 participants performed tasks using MuZeeker and a customized Google search engine. In both experiments web-based and mobile user interfaces were used. The experiment shows that participants are capable of solving tasks slightly better using MuZeeker, while the " inexperienced" MuZeeker users perform slightly slower than experienced Google users. This was found in both the web-based and the mobile applications. It was found that task performance in the mobile search applications (MuZeeker and Google) was 2-2.5 times lower than the corresponding web-based search applications (MuZeeker and Google).||0||0|
|Editing Wikipedia content by screen reader: Easier interaction with the Accessible Rich Internet Applications suite||Marina Buzzi
|Disability and Rehabilitation: Assistive Technology||English||2009||Purpose.This study aims to improve Wikipedia usability for the blind and promote the application of standards relating to Web accessibility and usability. Method.First, accessibility and usability of Wikipedia home, search result and edit pages are analysed using the JAWS screen reader; next, suggestions for improving interaction are proposed and a new Wikipedia editing interface built. Most of the improvements were obtained using the Accessible Rich Internet Applications WAI-ARIA suite, developed by the World Wide Web Consortium W3C within the framework of the Web Accessibility Initiative WAI. Last, a scenario of use compares interaction of blind people with the original and the modified interfaces. Results.Our study highlights that although all contents are accessible via screen reader, usability issues exist due to the user's difficulties when interacting with the interface. The scenario of use shows how building an editing interface with the W3C WAI-ARIA suite eliminates many obstacles that can prevent blind users from actively contributing to Wikipedia. Conclusion.The modified Wikipedia editing page is simpler to use via a screen reader than the original one because ARIA ensures a page overview, rapid navigation, and total control of what is happening in the interface.||0||0|

|Enhancing Wikipedia editing with WAI-ARIA||Caterina Senette
|Lecture Notes in Computer Science||English||2009||Nowadays Web 2.0 applications allow anyone to create, share and edit on-line content, but accessibility and usability issues still exist. For instance, Wikipedia presents many difficulties for blind users, especially when they want to write or edit articles. In a previous stage of our study we proposed and discussed how to apply the W3C ARIA suite to simplify the Wikipedia editing page when interacting via screen reader. In this paper we present the results of a user test involving totally blind end-users as they interacted with both the original and the modified Wikipedia editing pages. Specifically, the purpose of the test was to compare the editing and formatting process for original and ARIA-implemented Wikipedia user interfaces, and to evaluate the improvements.||0||0|
|Exploring the effects of experience on wiki anxiety and wiki usability: An online study||Cowan B.R.
|People and Computers XXIII Celebrating People and Technology - Proceedings of HCI 2009||English||2009||Information Technology is now pervasive in Higher Education institutions and developments in IT are changing the technological landscape at Universities. A recent phenomenon shaping such changes is the use of Web 2.0 tools in a pedagogical context. These tools are often included into a University's IT mix without full appreciation of the possible negative emotions student users may have towards these tools. It is generally assumed that experience with the IT system will be enough to reduce any anxious feelings which may manifest in users about such systems. This study firstly aims to observe the relationship that such emotion may have on usability evaluation of a wiki system. It also aims to investigate the effect of experience on students' negative affective reactions towards a wiki tool. Second year undergraduate psychology students (N=92) who were using a wiki to collaborate on course projects completed questionnaires measuring usability evaluation and anxiety towards the wiki both 2 weeks (Time 1) and 12 weeks (Time 2) into their usage of the system. The research found that wiki anxiety was negatively correlated to participants' usability evaluations of the wiki at both time 1 and time 2. Further experience with the system had little effect on users' negative emotions towards the wiki. Users also showed little change in their usability rating of the system with more exposure to the wiki. However any change in wiki anxiety over the study was negatively correlated with a change in usability evaluation. Possible interpretations of the relationship between wiki anxiety, wiki usability and possible effects of the type and quality of user experience on wiki anxiety are discussed.||0||0|

|KnowIT, a semantic informatics knowledge management system||Alquier L.
|WikiSym||English||2009||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. Copyright||0||0|
|Is Wikipedia usable for the blind?||Marina Buzzi

|Are Wikis Usable?||Alain Désilets
Norman G. Vinson
|WikiSym||English||2005||Wikis are simple to use, asynchronous, Web-based collaborative hypertext authoring systems which are quickly gaining in popularity. In spite of much anecdotal evidence to the effect that wikis are usable by non technical experts, this has never been studied formally. In this paper, we studied the usability of a wiki through observation and problem-solving interaction with several children who used the tool to collaboratively author hypertext stories over several sessions. The children received a minimal amount of instruction, but were able to ask for help during their work sessions. Despite minimal instruction, 5 out of 6 teams were able to complete their story. Our data indicate that the major usability problems were related to hyperlink management. We report on this and other usability issues, and provide suggestions for improving the usability of wikis. Our analysis and conclusions also apply to hypertext authoring with non wiki-based tools.||0||2|
