Passages
A passage is a short, continuous piece of a filing, such as a paragraph of an earnings release. Every extracted fact links to the passage it came from, so you can read the company's own words behind any number on the graph.
Where they come from
The lab reads each earnings release, Exhibit 99.1 to a company's 8-K filing, converts it to text and cuts it into passages. Each passage keeps its place in the document (where it starts and ends) and an id that never changes, so it can be cited reliably.
Why every fact has one
The ontology requires an extracted fact to say where it came from, and a fact without a passage is not recorded. When you open a fact, the panel shows the passage text under Extracted from, with a link to the source filing on the SEC's site.
One id, two uses
The same passage id is used by the search index the chat retrieves from and by the graph. That is what lets an answer cite a passage and the graph light up the facts read from it. See the chat.
