Crowdsourcing Dialect Characterization through Twitter
Featured paper
Dr. Gonçalves and Dr. Sànchez have used NodeXL to analyze Twitter messages written in Spanish.

We perform a large-scale analysis of language diatopic variation using geotagged microblogging datasets. By collecting all Twitter messages written in Spanish over more than two years, we build a corpus from which a carefully selected list of concepts allows us to characterize Spanish varieties on a global scale. A cluster analysis proves the existence of well defined macroregions sharing common lexical properties. Remarkably enough, we find that Spanish language is split into two superdialects, namely, an urban speech used across major American and Spanish citites and a diverse form that encompasses rural areas and small towns. The latter can be further clustered into smaller varieties with a stronger regional character.

Using Smartphone Apps in STD Interviews to Find Sexual Partners
Featured paper
The Monroe County Department of Public Health in Rochester, NY has conducted a sexually transmitted diseases (STDs) investigation in 2013. They used smartphone apps to enhance contact elicitation during field interviews and visualized patients' social network by the NodeXL tool. The report will be published on Public Health Reports in May 2015.

Smartphone applications (apps) are increasingly used to facilitate casual sexual relationships, increasing the risk of sexually transmitted diseases (STDs). In STD investigations, traditional contact elicitation methods can be enhanced with smartphone technology during field interviews.
In 2013, the Monroe County Department of Public Health conducted a large, multi-infection STD investigation among men who have sex with men (MSM) using both index case and cluster interviews. When patients indicated meeting sexual partners online, disease intervention specialists (DISs) had access to smartphone apps and were able to elicit partners through access to inboxes and profiles where traditional contact information was lacking. Social network mapping was used to display the extent of the investigation and the impact of access to smartphones on the investigation.
