Relations Between Actions Performed by Users and Their Engagement.

Although Galleries, Libraries, Archives, and Museums (GLAMs) increasingly encourage users to assist in the curation of online collections through open collaboration systems, measuring users’ engagement in these systems is a dynamic and complex challenge. We analyzed 18 user’s actions over 20 days according to the User Engagement Scale (UES) and based on Maximal Repeating Patterns (MRPs) and correlations between user interaction elements and dimensions of user engagement (focused attention, perceived usability, aesthetics, and reward). Our results show differences in usage tactics for users with high, medium, and low scores from UES, and monotonically increasing moderate correlations between perceived usability scores and game design elements. Additionally, we found that the longer the mean time interval between two consecutive user actions during a usage period lasted, the higher the UES score was. These results help to understand what influences user engagement, isolating the effects of user interaction elements.

Improving Engagement Metrics in an Open Collaboration Community Through Notification: An Online Field Experiment

Open collaboration communities depend on contributors. To foster users’ engagement with collaborative systems, it is necessary to consider features related to engagement attributes, such as awareness, control, novelty, and feedback, among others. However, it is not trivial to develop a feature that effectively improves engagement, considering specific contexts. This study analyzes the notification feature with respect to its effectiveness on increasing users’ engagement in open collaboration communities. We conducted an online field experiment in a real setting, analyzing the engagement of two homogeneous user groups: pre- and post-implementation of a notification feature. We measured users’ engagement using recency, frequency, duration, virality, and ratings metrics. There was an improvement in frequency, recency, and duration of users after inserting the notification feature. Considering the virality metric, there were changes in the behavior of users that accessed the notification interface, but there was neither influence of the notification on the virality metric from accesses through Facebook or Google+, nor on the ratings from comments and evaluations of system contents. Our results indicate an improvement of the user’s engagement, as four of the five engagement metrics had positive results.

Arquigrafia-Brasil Social Network: Design of an Online Environment Based on Transdisciplinarity and Collaboration

The Web2.0 has opened a great opportunity for collaborative social environments. This article presents a transdisciplinary project named “Arquigrafia-Brasil Social Network”, which aims the development of a user centered collaborative environment to document and study Brazilian architecture through images. It may play an important role in the architecture knowledge construction.
