Portuguese geolocated tweets: an overview

This paper describes an existing database of geolocated tweets that were produced in Portuguese regions. The existing database was collected during eight consecutive days and contains about 307K tweets, produced by about 11K different users. A detailed analysis on the content of the messages suggests a predominance of teenagers and young adult authors that use Twitter as a way to communicate their feelings, ideas and comments to their colleagues. An overview of the dataset suggests that tweets have a very personal content, often describing family bonds and school activities and concerns. This is a suitable source of information for a number of tasks, including sociolinguistic studies, sentiment analysis, among others.
