What is a source citation in AI?
A source citation shows which document and section an AI answer builds on, so that the reader can check it.
An answer without a source cannot be tested. With a citation, the colleague can open the document and see the passage the answer comes from.
That makes it easier to trust the answers and to notice when something is wrong. If the source is an old version, it shows straight away.
A case officer who gets an answer about processing times sees that it comes from the third section of the routine. She can click through and read the context before she replies to a customer.
How it works
When a system answers from your own documents, it knows which passages were sent to the model. The citation is built from exactly those. A good system shows the document name and the section, with a link. It can also show the passage itself, so the reader sees the words the answer rests on.
Why it matters
Sources make AI usable where people must be able to stand behind an answer. A case officer, a lawyer or a nurse needs to show what an answer is based on. Citations also make mistakes visible, which helps whoever maintains the documents see what needs fixing.
What to keep in mind
Check the citation when the answer matters. A passage can come from the right document and still be about something other than the question.
Be wary of sources that look like references but cannot be opened. A language model answering from memory can write names of documents and clauses that do not exist.
What it means for you
Require every answer to show its source. It is the simplest way to review what AI says.
Common questions
Is it enough for the answer to name a document?
It works best when the citation points to the section, so the reader finds the right place quickly. A reference to a whole document is harder to check.
Can a source citation be wrong?
Yes, if the system shows a source the answer is not actually based on. The citation should come from the passages that were read, and the reader should be able to open them.
Why do sources build trust?
They make the answer checkable. The reader sees the material for themselves and does not have to take the answer on trust.
