One Theme, Infinite Interpretations. Exploring Perspective Through Photo Sharing., Avery Gosselin
Honors College
In this creative Honors Thesis project, I have developed an initial, beta version, of an application that celebrates diverse perspectives through photo sharing within an interactive mobile interface. This application, titled NüLens and developed using the React Native framework, takes the form of a participatory digital art project, where members of the public have captured and submitted photos that (in their eyes) represent a predefined theme (in this initial release, the theme of nature). These photos were then aggregated into a mosaic of all other user-submitted photos relating to that theme, along with options to filter and sort the images …

Journal of Spatial Information Science
With the ubiquitous use of location-based services, large-scale individual-level location data has been widely collected through location-awareness devices. Geoprivacy concerns arise on the issues of user identity de-anonymization and location exposure. In this work, we investigate the effectiveness of geomasking techniques for protecting the geoprivacy of active Twitter users who frequently share geotagged tweets in their home and work locations. By analyzing over 38,000 geotagged tweets of 93 active Twitter users in three U.S. cities, the two-dimensional Gaussian masking technique with proper standard deviation settings is found to be more effective to protect user's location privacy while sacrificing geospatial analytical …

An abundance of geographic information is hidden within texts and multimedia objects that has the potential to enrich our knowledge about the relationship between people and places. One such example is the geographic information embedded within user-generated content collected and curated by the social media giants. Such geographic data can be encoded either explicitly as geotags or implicitly as geographical references expressed as texts that comprise part of a title or image caption. To use such data for knowledge building there is a need for new mapping interfaces. These interfaces should support both data integration and visualization, and geographical exploration …
