- Definitions: A claim is defined in relation to a claim template, which is a sentence that states, in general terms, a belief someone might hold about a topic within the COVID-19 Global Pandemic scenario. Within each claim template is an X Variable that can be filled by some piece of information. The following are examples of a claim template: X created SARS-CoV-2; X cures COVID-19. A claim, then, is a statement made implicitly or explicitly in or throughout a document that fills in the X Variable in a claim template. A claim also includes all of the informational context surrounding the claim, such as who is making the claim, when and where the claim was made, how the person making the claim feels about the claim, etc. At the center of a claim is the core claim, which refers to the root claim itself without any of the surrounding informational context. In the CRUX evaluation (as in AIDA), all relevant information about a single claim in a document is represented in a claim frame; in addition to what is being claimed, the claim frame includes other fields that correspond to the various pieces of information about the claim, including who is making the claim, when the claim is made, etc. For further details, please see the principles for claim frame annotation in the annotation data package documentation.
- The CRUX track has two evaluation tasks:
- Task 1: Extract all claims about targeted topics from a corpus of documents: For each input document, find all claims about the targeted topics that are expressed in the document, and populate the claim frame for that claim with the information found in the document, following the annotation principles for claim frame annotation.
- Task 2: Identify cross-claim relations: For each given pair of claims, determine the relation between the two claims (identical, supporting, refuting, related, or unrelated).
