Interpretation means take whatever data is available to you and translate it into a ratings format that is ready to be digested by the GrapeRank algo.

For example: if Alice follows Bob, I INTERPRET the follow AS IF she had issued a rating in the GrapeRank format. Which she didn’t, of course, but that’s why I call it “interpretation.”

The format requires 5 fields:

- context (string)

- rater (string)

- ratee (string)

- rating (number)

- confidence (number between 0 and 1)

At my site right now, every follow and every mute is INTERPRETED as a rating, issued by one pubkey to another pubkey. The context is something like: Real Nostr User. The rating field is a 1 or 0 for follow or mute, respectively. The confidence is 0.03 or 0.5 for a follow or a mute, respectively.

The final GR Real Nostr User influence score is a number that is suitable to be a weight in a weighted average (eg, to calculate ratings at Yelpstr if such an app were to exist). It is a number between 0 and 1, where 1 means “verified Real Nostr User.”

If we were to use PageRank to calculate average scores of businesses at Yelpstr, the opinions of the K Kardashians of the world would dominate. If we were to use the GrapeRank “Real Nostr User” score, the opinions of K Kardashian and A Einstein would carry roughly equal weight.
