|
|
# If there are many students with the same school name, it's either correct or a rename must happen.

# If the school name is unique but similar to a school name with many students, it's probably incorrect.
|
|
# But if we determine it is correct, how can we record this fact so it doesn't keep asking?
|
|
|
|
# How can we infer the school name when we think it's not correct?

|
# We look for users with confident schoolNames in shared courseInstances.
|
|
# ... in shared clans.
|
|
# ... with the same lastIP that doesn't cover the lastIP of students from multiple schools.
|
|
# If we find a school-district-formatted email domain, we could try to match to other schoolNames in that domain, but I doubt that will be helpful until we have a lot of data and a lot of time to manually look things up.
