AIDA Scenario 1 Practice Topic Annotation

AIDA Scenario 1 Practice Topic Annotation was developed by the Linguistic Data Consortium (LDC) and is comprised of annotations for 212 English, Russian and Ukrainian web documents (text, image and video) from AIDA Scenario 1 Practice Topic Source Data (LDC2023T11). The DARPA AIDA (Active Interpretation of Disparate Alternatives) program aimed to develop a multi-hypothesis semantic engine to generate explicit alternative interpretations of events, situations and trends from a variety of unstructured sources. LDC supported AIDA by collecting, creating and annotating multimodal linguistic resources in multiple languages. Each phase of the AIDA program centered on a specific scenario, or broad topic area, with related subtopics designated as either practice subtopics or evaluation subtopics. The Phase 1 scenario focused on political relations between Russia and Ukraine in the 2010s. This corpus contains annotations for the set of practice documents designated for annotation in Phase 1.
