The Sentinel platform provides a multi-level interface into information extracted from the social Web. The purpose of this platform is to evaluate to what degree web data can be converted into actionable intelligence relating to public-interest events and topics in terms of reliability, usability and timeliness. We focus upon five key questions that can allow human analysts to draw conclusions as to:

What is happening? When is it taking place?

Where is it occurring? Who are the sides involved?

Why is this happening and why does it require response?

Users of Sentinel are able to direct data collec-tion towards specific key words and geographical locations creating “channels” of interest by which intelligence can be derived.

WHAT’S THE KEY IDEA?

Sentinel: Localised Situational Awareness via Social Media60 SECOND BRIEFING

The data driven text mining tool Flexi-Term[1] has been incorporated into the interface, allowing for a near real time sum-mary of prevailing terms currently found within a channel, with the output being presented spatially and temporally.

Running parallel to topic identification is the indexing of data against an expertly curated ontology of criminal and extremist topics. This provides users with the ability to delve deep into their data channels to identify and track sensitive narratives.

We take advantage of the pervasive-ness of Cloud Computing to create a dynamic and scalable approach to data processing that provides the ability to extract near real time meaning from large volumes of data.

This takes the form of a data processing pipeline in which fragments of social media text are filtered, transformed and enriched by a pool of processing and analytic tools.

CASE STUDY: WOOLWICH INCIDENT22nd May 2013, killing of Lee Rigby in Woolwich

Aggressive reaction from English Defence League

Widespread attention from Social Media (464,196 Tweets)

Named Entity Recognition will identify “Who?” and “Where?”Usability study of interfaces with end usersInvestigation into the demographics of data sources

Created a multi-level interface into the infor-mation we extract.Topic identification is achieved through the use of Flexi-TermProvides both temporal and geographical reference planesAnswers the questions “What? When?” and “What? Where?”
