Abstract

An AI-based event grounding system is provided. The event grounding system includes an input device, an output device, a graphic processing unit (GPU); and a processor. The processor connects the input device, the output device, and the GPU. The event grounding system receives a free-text through the input device, and the processor perform an event grounding to the free-text through the GPU. The GPU performs event acquisition from the free-text using semantic parsing and acquires a plurality of verb-centric events, and performs event abstraction and acquires a plurality of abstract events, and grounds the abstract events to a plurality of anchor events of an event-centric KG, and reasons a subgraph through a reasoning model, and the subgraph includes the abstract events and the anchor events. The GPU generates a prediction based on the reasoning and provide the prediction through the processor and the output device.
