AIDA Scenario 3 Practice Topic Source Data and Annotation

AIDA Scenario 3 Practice Topic Source Data and Annotation was developed by the Linguistic Data Consortium (LDC) and is comprised of English, Russian and Spanish web documents (text, video, image) and annotations. 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 3 scenario focused on the COVID-19 global pandemic. This corpus contains source documents and annotations for the Scenario 3 practice topics.
