AIDA Scenario 1 Practice Topic Source Data

<h3>Introduction</h3>
<p>AIDA Scenario 1 Practice Topic Source Data was developed by the Linguistic Data Consortium (LDC) and is comprised of 1511 root documents (text, image, and video) from English, Russian, and Ukrainian web sources.</p>
<p>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.</p>
<p>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 constitutes the full set of topic-focused documents for Phase 1 practice subtopics.&nbsp;</p>
<h3>Data</h3>
<p>Data was collected from web sources by a combination of automatic and manual processes. HTML content was converted from its original form into XML. To the extent possible, all resources referenced by a given "root" HTML page (style sheets, javascript, images, media files, etc.) were stored as separate files of the given data type and assigned separate 9-character file-IDs (the same form of ID used for the "root" HTML page).</p>
<p>The knowledge base for entity detection and linking annotation for all AIDA Scenario 1 and 2 corpora is available separately as <a href="../../../LDC2023T10">AIDA Scenario 1 and 2 Reference Knowledge Base (LDC2023T10)</a>.</p>
