The automatic detection of online illegal content (either content that facilitates radicalisation or promoting crime activities or provides instructions of how to perform them) is a much-needed capability for LEAs. The capability gap arises from the vast amount of open-source data that needs to be searched by the Open-Source Intelligence Team (OSINT). Nowadays OSINT teams are using either commercial tools but with limited number of licenses or restricted functionalities because of their acquisition cost or in-house customised open-source tools. As such an automated Early Warning System is needed, with adequate licenses to utilise LEA’s capacity in OSINT.
