示例1: setFeaturesTest
# 需要导入模块: from Datum import Datum [as 别名]
# 或者: from Datum.Datum import features [as 别名]
def setFeaturesTest(self, data):
newData = []
words = []
labels = []
labelIndex = {}
for datum in data:
words.append(datum.word)
if not labelIndex.has_key(datum.label):
labelIndex[datum.label] = len(labels)
labels.append(datum.label)
## This is so that the feature factory code doesn't
## accidentally use the true label info
for i in range(0, len(data)):
datum = data[i]
if i == 0:
previousLabel = "O"
datum.features = self.computeFeatures(words, previousLabel, i)
newDatum = Datum(datum.word, datum.label)
newDatum.features = self.computeFeatures(words, previousLabel, i)
newDatum.previousLabel = previousLabel
newData.append(newDatum)
else:
for previousLabel in labels:
datum.features = self.computeFeatures(words, previousLabel, i)
newDatum = Datum(datum.word, datum.label)
newDatum.features = self.computeFeatures(words, previousLabel, i)
newDatum.previousLabel = previousLabel
newData.append(newDatum)
return newData示例2: setFeaturesTrain
# 需要导入模块: from Datum import Datum [as 别名]
# 或者: from Datum.Datum import features [as 别名]
def setFeaturesTrain(self, data):
newData = []
words = []
for datum in data:

## This is so that the feature factory code doesn't
## accidentally use the true label info
previousLabel = "O"
for i in range(0, len(data)):
