Quickstart

No persistence

import pycrm114

crm = pycrm114.CRM114(classes=["spam", "ham"])
crm.learn("spam", "foo bar")
crm.learn("ham", "bar is good")
assert crm.classify("is bar good")["class"] == "ham"
assert crm.classify("foo bar good")["class"] == "spam"
crm.forget("spam", "foo bar")
assert crm.classify("foo bar good")["class"] == "ham"

File System Persistence

import pycrm114

crm = pycrm114.CRM114(
    classes=["spam", "ham"],
    storage=pycrm.storage.FileSystemStorage("/var/tmp/crm-test")
)
crm.learn("spam", "foo bar")
crm.learn("ham", "bar is good")
crm.save()
new_crm = pycrm114.CRM114(
    classes=["spam", "ham"],
    storage=pycrm.storage.FileSystemStorage("/var/tmp/crm-test")
)
assert new_crm.classify("is bar good")["class"] == "ham"
assert new_crm.classify("foo bar good")["class"] == "spam"
