> I can fix it in my own dictionary immediately. If I submit the correction to Google, it just changes some weightings, and hundreds of people will have to submit the same correction before their deep learning will finally catch on that it needs to change something. This isn't a problem with deep learning, but a problem with verifying a data source. You are trusting yourself to submit a proper correction, but Google doesn't know you from John. To use another example, imagine that someone says 他的 is "they're", another person says it's "their", and still another person says it's "there". Your approach would just accept all three in a row, wouldn't it? Google's approach presumably trusts that the crowd + what it sees on the web is correct and thus attempts to verify that a submission is typical language use before actually putting it into play.
