We can gather data re- lated to a specific place, ob ject or event that were shared or posted in vari- ous places (e.g., social net- works, CCTVs and body cams) or that were seized in an operation.
The main task consists of tying together different information pieces in a spatial and temporal coherent form (X-coherence). Space-time-coherent pieces can be exploited to have an overall idea of the event, place or object as a whole, as well as of specific points within the event’s timeline.
With X-coherent pieces, we can (i) look for specific clues (authorship, related topics); (ii) mine possible suspects, objects or places of interest through biometrics and machine learning techniques; (iii) counter fake propaganda and media repurposing through provenance analysis methods; and (iv) assess sensitive content through diverse filters (e.g., violence), everything underpinned by open-set recognition techniques.
