                         sequences of events. In this work, we propose Linea, a tool that 
                         helps users build timelines from unstructured text. Besides 
                         providing interactive tools for browsing, selecting, editing, and 
                         filtering events, Linea includes mechanisms to build smart 
                         defaults, thus providing good starting points for users to create 
                         their own timelines. The core component is a novel visualization 
                         widget called event matrix, a matrix designed to explore events 
                         over time and in different time scales. We illustrate the 
                         strengths of our tool with a case study showing that important 
                         events can be browsed, timelines can be easily built, and show the 
                         result of an information user evaluation.",
