| 2 | Visualizing perceived spatial data quality of 3D objects within virtual globes显示文摘Virtual globes(VGs)allow Internet users to view geographic data of heterogeneous quality created by other users.This article presents a new approach for collecting and visualizing information about the perceived quality of 3D data in VGs.It aims atimproving users’awareness of the qualityof 3D objects.Instead of relying onthe existing metadata or on formal accuracy assessments that are often impossible in practice,we propose a crowd-sourced quality recommender system based on the five-star visualization method successful in other types of Web applications.Four alternative five-star visualizations were implemented in a Google Earth-based prototype and tested through a formal user evaluation.These tests helped identifying the most effective method for a 3D environment.Results indicate that while most websites use a visualization approach that shows a‘number of stars’,this method was the least preferred by participants.Instead,participants ranked the‘number within a star’method highest as it allowed reducing the visual clutter in urban settings,suggesting that 3D environments such as VGs require different designapproachesthan2Dornon-geographicapplications.Resultsalsoconfirmed that expert and non-expert users in geographic data share similar preferences for the most and least preferred visualization methods. | Krista Jones Rodolphe Devillers Yvan Bedard Olaf Schroth | 2014 | International Journal of Digital Earth2014，7，10： | 0 |
| 3 | Contributors’enrollment in collaborative online communities:the case of OpenStreetMap显示文摘The number of people registering in an online community depends on two main factors:interest in,and awareness of,the project.Registering to a project does not,however,imply contributing to it,as lacking the knowledge and skills can be a barrier to participation.In order to identify the nature of events that might have facilitated or hindered enrollments in the OpenStreetMap(OSM)project over time,we analyzed the correlations between the number of new participants and the events that dotted its history.Four different metrics were defined to characterize participants’behaviors:the daily number of registrations,the daily number of participants that made a first contribution,the delays between contributors’registration and their first edits,and a daily contribution ratio built from the number of new contributors and the number of new registered members.Time series analyses were used to identify trends,and outstanding variations of the number of participants.An inventory of events that took place along the OSM project’s history was created and appreciable variations of the metrics have been linked to events that seemed to be meaningful.Although a correlation does not imply causality,many of the explanations these correlations suggest are supported by the results of other studies,either directly or indirectly.For instance,when considering the time participants spend as“lurker”,as well as on the nature of the contribution of early participants.In other cases,they suggest new explanations for the origin of the spam accounts that affect registration statistics,or the decline in the proportion of registered members who actually become contributors. | Daniel Bégin Rodolphe Devillers Stéphane Roche | 2017 | Geo-Spatial Information Science2017，20，3： | 0 |
