                         mains, since users share their opinion and knowledge in (near) 
                         real-time. More- over, users usually use different words to refer 
                         to a particular event (e.g., a rain event). These words may be 
                         later employed to filter social media messages re- garding new 
                         occurrences of the event and, thus, to reduce the number of unre- 
                         lated messages. These words, however, may have different meanings 
                         and, thus, may not reduce the number of messages. In this work, we 
                         conduct a case study to measure which rain- or flood-related 
                         keywords are less relevant to reduce the number of unrelated 
                         messages. The results show that the keywords change over space, 
                         due to local language/culture, and time, specially in different 
                         time scales.",
