One would think that Google, if no one else, has created some kind of approximate trust graph internally that it could utilize during training to emphasize "trusted" sources. I know that certain models have been trained more heavily on sources like Wikipedia, Arxiv, etc., but if there's a paper that uses finer-grained trust from a trust graph, I haven't seen it. Also would probably hurt more than help during COVID. Disclaimer: former Googler, but not involved in Search
