Harnessing collective intelligence to find missing children


Cordis: “It is estimated that over 250 000 children go missing every year in the EU. Statistics on their recovery is scant, but based on data from the EU-wide 116 000 hotline, 14 % of runaways and 57 % of migrant minors reported missing in 2019 had not been found by the end of the year. The EU-supported ChildRescue project has developed a collective intelligence and stakeholder communication approach for missing children investigations. It consists of a collaborative platform and two mobile apps available for organisations, verified volunteers and the general public. “ChildRescue is being used by our piloting organisations and is already becoming instrumental in missing children investigations. The public response has exceeded our expectations, with over 22 000 app downloads,” says project coordinator Christos Ntanos from the Decision Support Systems Laboratory at the National Technical University of Athens. ChildRescue has also published a white paper on the need for a comprehensive legal framework on missing unaccompanied migrant minors in the EU….

To assist in missing children investigations, ChildRescue trained machine learning algorithms to find underlying patterns useful for investigations. As input, they used structured information about individual cases combined with open data from multiple sources, alongside data from similar past cases. The ChildRescue community mobile app issues real-time alerts near places of interest, such as where a child was last seen. Citizens can respond with information, including photos, exclusively accessible by the organisation involved in the case. The quality, relevance and credibility of this feedback are assessed by an algorithm. The organisation can then pass information to the police and engage its own volunteers. Team members can share real-time information through a dedicated private collaboration space….(More)”.
