A. Data
Our system automatically collects data in real time from
the news sources. The number of news sources is potentially
unlimited and is a many to many relationship which means
that the same crawler can fetch many news sources and the
same news source can be fetched by many crawlers. The data
collected is stored in a database, filtered [14] then analyzed
by other components of the system.
We also use Baltimore shooting data [18] to predict incidents
locations for the 24 hours in the future.
