I would argue that having facts without context isn't knowing. I accept the definition of knowledge to be justified true belief. Ultimately this is a probabilistic argument, Solipsism cannot be overcome so we can never absolutely know anything but phenomenologically it is best to assume our external reality exists and functions roughly the way we perceive it. With absolute knowledge out of reach we need a functional construction to serve in it's place. Justified true belief is as close to absolute knowledge as we can achieve. In this construct belief uses it's conventional definition, true means that it doesn't contradict reality as we perceive it, and justified means that we can point to strong evidence in our perceived reality to support the belief. Without at least some context the belief cannot be justified so the thing cannot be known.
