In the past year the GAIA team has improved our end-to-end knowledge extraction, grounding, inference, clustering and hypothesis generation system that covers all languages (English, Russian and Ukrainian), data modalities and knowledge element types defined in new AIDA ontologies. We participated in the evaluations of all tasks within TA1, TA2 and TA3 and achieved highly competitive performance. Our TA1 system achieves top performance at both intrinsic evaluation and extrinsic evaluation through TA2 and TA3. The system incorporates a number of impactful and fresh research innovations
