Updating knowledge graph for fact based questions

[nvg24]

I recently ran the code to produce an updated knowledge graph(with the latest information). I assumed that this should help the model in answering factoids, for example, Who is the manager of Arsenal?

However, this does not work. I tried to dig a little deeper in the model and it seems that for questions that have come up in the training conversations, the model tends to give the same answers as the training data.

Is there a solution to this?
