Hitachi Data Systems, in a recent announcement, has upped the ante in the predictive policing game with the introduction of Visualization Predictive Crime Analytics (PCA) into their Visualization Suite. They claim:

PCA is the first tool of its kind to use real-time social media and Internet data feeds together with unique, sophisticated analytics to gather intelligent insight and enhance public safety through the delivery of highly accurate crime predictions.

The press release explicitly connects the technology to “smart cities,” claiming the suite will “help public and private entities accelerate extraction of rich, actionable insights from all of their data sources.” The use of the word “actionable” here is interesting and reminds me of Louise Amoore’s great article, “Data Derivatives: On the Emergence of a Security Risk Calculus for Our Times” from 2011. The data derivative, in Amoore’s articles, is the “flag, map or score” that is inferred from large data sets like those used in Hitachi’s PCA system. She argues:

The pre-emptive deployment of a data derivative does not seek to predict the future, as in systems of pattern recognition that track forward from past data, for example, because it is precisely indifferent to whether a particular event occurs or not. What matters instead is the capacity to act in the face of uncertainty, to render data actionable.

The whole project seems wildly ambitious, with unknown statistical models, machine learning algorithms, and natural language processing routines holding it all together. More from the press release:

Hitachi Visualization Suite (HVS) is a hybrid cloud-based platform that integrates disparate data and video assets from public safety systems—911 computer-aided dispatch, license plate readers, gunshot sensors, and so on—in real time and presents them geospatially. HVS provides law enforcement with critical insight to improve intelligence, enhance investigative capabilities and increase operational efficiencies. Along with capturing real-time event data from sensors, HVS now offers the ability to provide geospatial visualizations for historical crime data in several forms, including heat maps. This feature is available in the Hitachi Visualization Predictive Crime Analytics (PCA) add-on module of the new Hitachi Visualization Suite 4.5 software release.

Blending real-time event data captured from public safety systems and sensors with historical and contextual crime data from record management systems, social media and other sources, PCA’s powerful spatial and temporal prediction algorithms help law enforcement and first responder teams assign threat levels for every city block. The algorithms can also be used to create threat level predictions to accurately forecast where crimes are likely to occur or additional resources are likely to be needed. PCA is unique in that it provides users with a better understanding of the underlying risk factors that generate or mitigate crime. It is the first predictive policing tool that uses natural language processing for topic intensity modeling using social media networks together with other public and private data feeds in real time to deliver highly accurate crime predictions.
