11. A system comprising: a physical processor that executes machine readable instructions that cause the system to: identify, based on disseminated information from a first geographic region, an event occurring in the first geographic region, wherein the disseminated information from the first geographic region includes public commentary from the first geographic region; determine a set of attributes related to the event; extract a set of sentiment words relating to the identified event from the disseminated information, where the extracted set of sentiment words are in a local language of the first geographic region; associate, for each attribute of the set of attributes, a sentiment from the set of sentiment words; and cause display of a sentiment trend visualization that depicts a trend of determined sentiments for the first attribute, wherein the determined sentiments are based on the set of sentiment words for the first attribute.
11. A system comprising: a physical processor that executes machine readable instructions that cause the system to: identify, based on disseminated information from a first geographic region, an event occurring in the first geographic region, wherein the disseminated information from the first geographic region includes public commentary from the first geographic region; determine a set of attributes related to the event; extract a set of sentiment words relating to the identified event from the disseminated information, where the extracted set of sentiment words are in a local language of the first geographic region; associate, for each attribute of the set of attributes, a sentiment from the set of sentiment words; and cause display of a sentiment trend visualization that depicts a trend of determined sentiments for the first attribute, wherein the determined sentiments are based on the set of sentiment words for the first attribute. 14. The system of claim 11 , wherein the physical processor executes machine readable instructions that cause the system to: access a set of sentiment scores associated with the first attribute, where each sentiment score of the set of the sentiment scores expresses a sentiment associated with the first attribute of a respective data record of the set of data records at a respective time; aggregate a subset of sentiment scores of the set of sentiment scores within each time interval of a sequence of time intervals; compute, for a first time interval of the sequence of time intervals, a first aggregate score of a first subset of sentiment scores associated with the first time interval; wherein the sentiment trend visualization of the particular attribute comprises a graph of the first aggregate score.
