Suppose Harry Potter and the Sorcerer's Stone is a fantasy novel written by J.K. Rowling. It follows the story of a young wizard named Harry Potter as he attends Hogwarts School of Witchcraft and Wizardry. The novel was first published in 1997 and is the first book in the Harry Potter series.
Can we infer that "Harry Potter is a non-fictional character in the novel."? Yes, no, or maybe?
