Retrieve factual knowledge from LMs

For example, to query the owner of MSN (Microsoft is the answer), you can either use manually created prompts (x is owned by y):

python lama/eval_generation.py --lm bert --t "MSN is owned by [MASK]."

or use LPAQA that ensembles a diversity of prompts:

# mined prompts
python lama/eval_ensemble.py --lm bert --subject MSN --relation P127 --prompts prompt/mine
# paraphrased prompts
python lama/eval_ensemble.py --lm bert --subject MSN --relation P127 --prompts prompt/paraphrase
