PowerCase Visual Analytics

Xanalys - Investigation Management Systems

PowerCase Visual Analytics

Xanalys has a long history in the development of software tools for the visualisation and analysis of graph-based data. Going back to the “Harlequin days” in the early 1990’s, Watson was used by dozens of agencies to draw link charts, import spreadsheet data for telephone call analysis, and connect to databases to query and visualise intelligence information.

The associations between entities is obviously vitally important to investigators and intelligence analysts, so directly integrating tools to quickly reveal and drill into these links provides the  PowerCase users not only ability to see how the entities they are investigating are related, but also how the processes and direction of the investigation are unfolding.


Part of our modernisation programme to offer .NET/web support for our PowerCase platform has been inclusion of visualisation of investigative data in a browser. 


Visualising information from any particular investigation provides useful insight into the associations and activities of those entities involved in the case. Extending this across cases provides entirely new insights into how individuals are involved in multiple incidents.

In the following chart, a search for a Person using their Surname/Given Name has been run across cases and the results displayed. The individual clusters reveal information concerning individual investigations.

To this chart, a set of “clustering” algorithms are applied by the user to virtually merge objects that are common across the chart e.g. telephone numbers, email addresses, locations, vehicles. This pulls the clusters together via the merged objects, demonstrating not only that these objects occurred in multiple cases, but drawing their associated objects together as also related.

On finding such outcomes, the managers of the different cases can collaborate to establish if the analytical findings lead to new directions in their cases.

Data Provenance

A unique aspect of the data schema that underlies all PowerCase solutiosn is that every aspect of the case is represented as a graph, i.e. objects and links. This not only includes investigative objects such as people, events, telephones, locations, and vehicles, etc., but the staff, documents, tasks, offences, decision notes, disclosure packs that map the activities of the investigative team and the information they collect.

The following chart demonstrates how the system can answer basic questions such as “what is the sources of this information?” or “why was this information collected?

  • The details and participants in these Events were derived from the contents of Paul Stephens interview, which itself was taken as a result of the Action A1 – “Interview Manager Paul Stephens.
  • The guest list attached to Officer Report R2A, was a result of the Action A14, which itself was derived from Statement S1, etc.

Dissemination is the last step of the Intelligence Cycle. Having collected, processed, and analysed the data, the data or findings can be shared with other users and interested parties. 

Broadly, this can take two different forms (i) a query that generates the content of the chart, or (ii) a snapshot of the relationships at this point in time.  While the first may display a different chart at a later time, a snapshot reveals what was known at that time. One way to generate a snapshot is to simply generate a PDF document containing the chart – this feature is available directly from the application toolbar.


We will be adding many new capabilities and features to the PowerCase Analytics charts in the near future, including a “bread-crumb” feature to allow users to inspect each step they took in generating any particular chart.

OPTIC pilots enhanced investigation technology from Xanalys Limited for Ontario Police Services

OPTIC pilots enhanced investigation technology from Xanalys Limited for Ontario Police Services

The Ontario Police Technology Information Cooperative (OPTIC) is undergoing a pilot project with a new technology tool for law enforcement officers in Ontario. The software, developed by Xanalys Limited, visualizes case data and gives officers the information they need in an easy-to-digest format.

Toronto, ON (PRWEB) May 11, 2015 opticThe Ontario Police Technology Information Cooperative (OPTIC) and Xanalys Limited – The Investigation Software Company™ announced today that the two parties are in a pilot project of technology designed to help police officers across Ontario gain better insight into investigations through powerful data visualization and link analysis technology. Link analysis software helps analysts and investigators understand hidden connections between people, places, and things within the course of an investigation. OPTIC is one of the largest law enforcement data-sharing cooperatives in North America with over 9,100 officers from 43 Police and Law Enforcement agencies and the Ontario Provincial Police (OPP) using a single records management system (RMS) from Winnipeg-based Niche Technology. Within the OPTIC community, all general police domain data such as incidents, police reports, and digital mug shots is shared. Xanalys’ Link Analysis software is designed to help officers quickly access this shared data through an intuitive, visual representation of the underlying RMS data. “Our software, Link Explorer Enterprise (LEE) is powerful link analysis software designed to visually indicate to officers how individuals and incidents are connected, despite deliberate attempts by criminals to hide those relationships”, said Douglas Wood, Xanalys’ VP of Corporate Development. “With this proof of concept in place, we believe that law enforcement officials will be more informed and productive through visual representations of patterns that are otherwise difficult to detect.” “The mission of OPTIC is to enhance public safety in Ontario by providing state-of-the-art information technology and data management systems”, added Paul Hamelin, executive director of OPTIC. “We hope that the proof of concept underway with Xanalys gives officers the information they need in a format they can easily digest. It would be yet another significant step in the ongoing process of ensuring that Ontario law enforcement officers have the information they need to better serve their communities.” Another of Xanalys’ products, PowerCase™, is currently used by the Ontario Ministry of Community Safety and Correctional Services as the core technology behind the province-wide Major Case Management (MCM) initiative. PowerCase is used by all Ontario police forces to investigate major crimes including murders, sexual assaults, and abductions. The pilot project is expected to run through spring of 2015. About OPTIC: The Ontario Police Technology Information Cooperative is a provincial law enforcement technology initiative. OPTIC provides state-of-the-art information technology and data management systems that include records management, computer aided dispatch, and data networks to 44 member jurisdictions.
