Knowledge graph handles out-of-order LLM facts by prioritizing world time

By PulseAugur Editorial · [1 sources] ·

A personal knowledge graph implementation addresses the challenge of handling out-of-order data by prioritizing world time over arrival time for fact validity. When a new fact arrives that describes an earlier state than the current one, it is filed as historical data with an `invalid_at` timestamp and a `superseded_by` link, rather than overwriting the existing current fact. This approach ensures that the most accurate representation of the world's state is maintained, with exceptions made for predicates like deadlines where earlier times represent legitimate updates.

    Late facts shouldn't overwrite newer ones: handling out-of-order state in a temporal knowledge graph

    <p>When you extract facts from someone's messages with an LLM, they don't arrive in order. A re-extraction, a history backfill or an out-of-order batch will happily deliver <em>yesterday's truth</em> after <em>today's</em>. If your store decides "what is current" by arrival order…
