programmatically determined link context

  additional information that can be programmatically determined from relationships with a link, combined with the link text, and presented to users in different modalities

  In HTML, information that is programmatically determinable from a link in English includes text that is in the same paragraph, list item, or table cell as the link or in a table header cell that is associated with the table cell that contains the link.

  Since screen readers interpret punctuation, they can also provide the context from the current sentence, when the focus is on a link in that sentence.
