AIDA Scenario 2 Practice Topic Source Data

<h3>Introduction</h3>
<p>AIDA Scenario 2 Practice Topic Source Data was developed by the Linguistic Data Consortium (LDC) and is comprised of 1500 root documents, including text, image, and video, from English, Russian, and Spanish 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 2 scenario focused on the socioeconomic and political crisis in Venezuela since 2010. This corpus constitutes the full set of topic-focused documents for Phase 2 practice subtopics.</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&nbsp;<a href="../../../LDC2023T10">AIDA Scenario 1 and 2 Reference Knowledge Base (LDC2023T10)</a>.</p>
