    It has always been a big problem to track down or spot a criminal, but now big data is helping in a big way. Publicly shared information combined with data from local authorities, social services and intelligence gathered by beat officers is helping police forces around the world spot trouble before it starts. 

Pre-crime

"It's about using big data and analytics in a smarter way. You are just giving them access to information that they never used to have before." said a former policeman Shaun Hipgrave. It helps the police be much less reactive, and slowly starts to reveal the real trouble spots and troublemakers in a neighborhood, estate or street. The data analytics software links up with government initiatives on so-called "troubled families" that can be the nexus of a lot of problems in some towns and cities.

 
Gun Crime
    Big data analytics is also increasingly important in the fight against cross-border crime. Back in 1999, detectives had to call police forces in other countries individually to find information about the bullet and the type of gun that might have been fired. Weapons and their ammunition regularly cross borders and pass through the hands of many dedicated and serious criminals. Analytics and a database called Odyssey mean information about when which weapon was used, and what was fired, is now much easier to come by.

Sex abuse

    Typically, police forces are confronted with gigabytes and sometimes terabytes of data when they arrest a pedophile or raid someone who runs a service that trades in images of child sex abuse. The situation is complicated by the fact that images and videos of abuse are widely traded. Without big data analytics police officers could spend a lot of time literally retracing the steps of other forces that have already worked out who was behind one set of images or who they depict. A cross-European project is helping police forces spot the novel material more quickly, said Mr Hoffman, adding that the analysis has led to a series of successes against abusers.

    I think big data is really helping a lot of different areas in the world. This article focus on crime fighting and how big data is helping with it. I think is very interesting to learn different ways of how big data is changing things. The article mentions that because of public shared information by locals authorities, social services, and intelligence gathered by beat officers is helping police officers around the world to prevent the crime by spotting the chaos before it has even started. They mention three types of crime: Pre-crime, gun crime and sex abuse. For the pre-crime it helps the police to be much less reactive and spot the real problem. It also helps government initiatives by linking information of troubled families that can be trouble makers in some towns and cities. In the fighting of gun crime big data helps to register which gun has been where and who has fired it. Guns tend to travel borders and go by many criminal hands so now information is more accurate and accessible. Lastly in the sex abuse part the article tell us about how difficult the investigation would be in order to arrest a pedophile or someone who runs a service that trades in images of child sex abuse because right now the police have many information but if big data was not a thing already it would take a lot of work plus it would be more time consuming.
    In conclusion big data helps police to fight crime and gather information of not only criminals, but potential criminals and their past. And also guns.

How Big Data Can Boost Weather Forecasting

張岳庭 D0741017 Source:  https://www.wired.com/insights/2013/02/how-big-data-can-boost-weather-forecasting/ Considering the number of variables involved and the complex interactions between these variables, weather forecasting has always been extremely challenging. The significant increase in data collection and processing capabilities has greatly improved the ability of weather forecasters to pinpoint the time and severity of hurricanes, floods, snowstorms and other weather events. Globally, more and more evidence of climate change is prompting governments and scientists to take action to protect people and property from its effects. But to take effective measures, they need to know more about the weather-from everything that will happen tomorrow to what will happen next year. According to the professor of economics and finance , Alan Anderson, PhD , “Example of an application of big data to weather forecasting is IBM’s Deep Thunder. Unlike many weather forecasting systems...
