示例1: open
# 需要导入模块: from vocabulary import Vocabulary [as 别名]
# 或者: from vocabulary.Vocabulary import get_features [as 别名]
from vocabulary import Vocabulary as Vocab
with open('spam_train.txt') as file:
train = file.readlines()
train = [ (int(line[0]), line[2:]) for line in train ]
with open('spam_validation.txt') as file:
valid = file.readlines()
valid = [ (int(line[0]), line[2:]) for line in valid ]
# Build the vocabulary
# (a list of distinct words frequent on the emails):
vocab = Vocab(train)
# Build a feature vector for each line of the data:
train = [ (line[0], vocab.get_features(line[1])) for line in train ]
valid = [ (line[0], vocab.get_features(line[1])) for line in valid ]
# Write it down:
with open('ex2-train-vecs.json', 'w') as file:
file.write(json.dumps(train))
with open('ex2-validation-vecs.json', 'w') as file:
file.write(json.dumps(valid))
with open('ex2-vocabulary.json', 'w') as file:
file.write(json.dumps(vocab.words))
