Enhancing Usability Evaluation of Web-Based Geographic Information
Enhancing Usability Evaluation of Web-Based Geographic Information Systems (WebGIS) with Visual Analytics René Unrau Institute for Geoinformatics, University of Münster, Germany Christian Kray Institute for Geoinformatics, University of Münster, Germany Abstract Many websites nowadays incorporate geospatial data that users interact with, for example, to filter search results or compare alternatives. These web-based geographic information systems (WebGIS) pose new challenges for usability evaluations as both the interaction with classic interface elements and with map-based visualizations have to be analyzed to understand user behavior. This paper proposes a new scalable approach that applies visual analytics to logged interaction data with WebGIS, which facilitates the interactive exploration and analysis of user behavior. In order to evaluate our approach, we implemented it as a toolkit that can be easily integrated into existing WebGIS. We then deployed the toolkit in a user study (N=60) with a realistic WebGIS and analyzed users’ interaction in a second study with usability experts (N=7). Our results indicate that the proposed approach is practically feasible, easy to integrate into existing systems, and facilitates insights into the usability of WebGIS. 2012 ACM Subject Classification Human-centered computing → User studies; Human-centered computing → Usability testing Keywords and phrases map interaction, usability evaluation, visual analytics Digital Object Identifier 10.4230/LIPIcs.GIScience.2021.I.15 Supplementary Material The source code is publicly available at https://github.com/ReneU/ session-viewer and includes configuration instructions for use in other scenarios. 1 Introduction Geospatial data has become a critical backbone of many web services available today, such as search engines, online booking sites, or open data portals [29]. -

The Culture of Wikipedia

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. Foreword Preface to the Web Edition Praise for Good Faith Collaboration Preface Extended Table of Contents "Reagle offers a compelling case that Wikipedia's most fascinating and unprecedented aspect isn't the encyclopedia itself — rather, it's the collaborative culture that underpins it: brawling, self-reflexive, funny, serious, and full-tilt committed to the 1.

Dashboards for SAS® Visual Analytics Laura Oliver, Experis Solutions
SESUG Paper 256-2019 Dashboards for SAS® Visual Analytics Laura Oliver, Experis Solutions ABSTRACT Visual Analytics is a great tool to use to visualize and analyze data and create dashboard for others to review data. The designer layout has multiple sections with multiple parts to each section. This paper will provide an introduction to the designer tool available for Visual Analytics. INTRODUCTION This paper is a companion to the Hands on Workshop (HOW), Dashboards for SAS® Visual Analytics. This paper will give an overall view of the report designer environment for Visual Analytics. It will show where data and objects are added as well as give an introduction to how objects can be customized to enhance the user experience. It will also touch on how to filter data at the data source and object level. VISUAL ANALYTICS DESIGNER LAYOUT The Visual Analytics development environment consists of 3 main sections. The section on the left has tabs for Objects, Data and Imports. The middle section is the canvas where the report is built. The section on the right provides options to customize objects that have been added to the report from the Objects tab. Each object has its own set of properties, styles, etc. Figure 1 - VA Development Environment 1 DATA TAB The first step in creating a report is adding a data source. This is done on the Data tab using the Select a data source drop down. The Add Data Source dialog box will open, allowing a data source to be selected. All data sources must have been previously uploaded to the LASR server to be available for use in a report. -
SAS Visual Analytics Tricks We Learned From
SESUG Paper RV-58-2017 SAS® Visual Analytics Tricks We Learned from Reading Hundreds of SAS® Community Posts Tricia Aanderud, Ryan Kumpfmiller; Zencos Consulting Rob Collum, SAS Institute ABSTRACT After you know the basics of SAS Visual Analytics, you realize there are some situations that require unique strategies. Sometimes tables are not structured right or become too large for the environment. Maybe creating the right custom calculation for a dashboard can be confusing. Geospatial data is hard to work with if you haven’t ever used it before. We looked through 100s of SAS Communities posts for the most common questions. These solutions (and a few extras) were extracted from the newly released Introduction to SAS Visual Analytics book. INTRODUCTION Our goal in writing the Introduction to SAS Visual Analytics book was to create a really practical and useful book for users. As part of the research for the book, we read hundreds of posts in the SAS Communities: SAS Visual Analytics section. This was a great exercise because we could confirm some of the sticking points that we know users have and pick up some tips to emphasize in the book as well. This paper combines our favorite tips from the book and some other ones that we think are worth sharing. Note: All examples were done using SAS Visual Analytics version 7.3 WHAT IS SAS COMMUNITIES? SAS Communities is an open forum on the SAS website, https://communities.sas.com, which connects SAS users all over the world. With over a hundred thousand members, users can post questions about challenges they are currently having working with SAS products or provide answers to other users who are looking for advice. -

Explaining Cultural Borders on Wikipedia Through Multilingual Co-Editing Activity

Out of the hypotheses we explored, bilingualism, available at the end of the article linguistic similarity of languages, and shared religion provide the best explanations for the similarity of interests between cultural communities. Population attraction and geographical proximity are also significant, but much weaker factors bringing communities together. In addition, we present an approach that allows for extracting significant cultural borders from editing activity of Wikipedia users, and comparing a set of hypotheses about the social mechanisms generating these borders.

The Case of Croatian Wikipedia: Encyclopaedia of Knowledge Or Encyclopaedia for the Nation?
The Case of Croatian Wikipedia: Encyclopaedia of Knowledge or Encyclopaedia for the Nation? 1 Authorial statement: This report represents the evaluation of the Croatian disinformation case by an external expert on the subject matter, who after conducting a thorough analysis of the Croatian community setting, provides three recommendations to address the ongoing challenges. The views and opinions expressed in this report are those of the author and do not necessarily reflect the official policy or position of the Wikimedia Foundation. The Wikimedia Foundation is publishing the report for transparency. Executive Summary Croatian Wikipedia (Hr.WP) has been struggling with content and conduct-related challenges, causing repeated concerns in the global volunteer community for more than a decade. With support of the Wikimedia Foundation Board of Trustees, the Foundation retained an external expert to evaluate the challenges faced by the project. The evaluation, conducted between February and May 2021, sought to assess whether there have been organized attempts to introduce disinformation into Croatian Wikipedia and whether the project has been captured by ideologically driven users who are structurally misaligned with Wikipedia’s five pillars guiding the traditional editorial project setup of the Wikipedia projects. Croatian Wikipedia represents the Croatian standard variant of the Serbo-Croatian language. Unlike other pluricentric Wikipedia language projects, such as English, French, German, and Spanish, Serbo-Croatian Wikipedia’s community was split up into Croatian, Bosnian, Serbian, and the original Serbo-Croatian wikis starting in 2003. The report concludes that this structure enabled local language communities to sort by points of view on each project, often falling along political party lines in the respective regions.
