首先，简历过滤需要一位数据处理专家对数据进行预处理，预处理的过程中，将申请人的degree，education，skills进行赋值处理。然后将所有数据分成训练集、测试集，并建立模型进行计算。计算出的结果，进行评分，并按照评分结果进行排名。分别按照：
第一步：数据的处理；
第二步：数据的分类汇总；
第三步：做出预测；
第四步：预测的AB测试；
第五步：预测的准确度；
第六步：汇总所有的codes并执行。
我参考的是James Brownlee在纯数据计算朴素贝叶斯模型的python代码。https://machinelearningmastery.com/naive-bayes-classifier-scratch-python/
数据处理的结果应该按照是如下格式：

假设：Degree: Bachelor=1, Master=2, Phd=4
Education1: 各高效排名参照国内高校排名赋值，权重为50%
Education2:对各高校计算机专业排名综合评分表排名, Fudan=80,Shanghai Jiao Tong=95, Nanjing=80，…，权重为50%
Education3:按照1：1比例计算出一个education的综合分
Skills里面分为：C++=100,Java=90,Python=98,SQL=80, …
Work Experience: ibm=80,Huawei=90,Microsoft=70,…
Position: dev为100， qa=80, manager=70, no hire=50
Years of Work Experience:
按照技能分隔符的个数赋值：比如一个技能赋值为1，两个技能赋值为2，以此类推等等。
Plus: 按照关键技能的关键词出现频率排名，其中debug为5，dev为4，program为4，test为3，…
（以上数据都是假设，具体计算的时候按照具体设计来进行，为了节约时间，我自动生成了一些随机的0到1的数字来补充空白的数字。）
这个数据库一共提供了72个记录，就是72个候选人的数据。
如果有no hire,可以赋值null数据为50。
数据集分类方法：
数据集可以按照67%训练集对33%测试的比例分配，在预测的时候将数据分为5份，并检验其数据的结果如何。
所有代码如下：
# Example of Naive Bayes implemented from Scratch in Python
import csv
import random
import math
def loadCsv(employeesdata1.csv)
lines = csv.reader(open(employeesdata1.csv, "rb"))
dataset = list(lines)
for i in range(len(dataset)):
dataset[i] = [float(x) for x in dataset[i]]
return dataset
def splitDataset(dataset, splitRatio):
trainSize = int(len(dataset) * splitRatio)
trainSet = []
copy = list(dataset)
while len(trainSet) < trainSize:
index = random.randrange(len(copy))
trainSet.append(copy.pop(index))
return [trainSet, copy]
def separateByClass(dataset):
separated = {}
for i in range(len(dataset)):
vector = dataset[i]
if (vector[-1] not in separated):
separated[vector[-1]] = []
separated[vector[-1]].append(vector)
return separated
def mean(numbers):
return sum(numbers)/float(len(numbers))
def stdev(numbers):
avg = mean(numbers)
variance = sum([pow(x-avg,2) for x in numbers])/float(len(numbers)-1)
return math.sqrt(variance)
def summarize(dataset):
summaries = [(mean(attribute), stdev(attribute)) for attribute in zip(*dataset)]
del summaries[-1]
return summaries
def summarizeByClass(dataset):
separated = separateByClass(dataset)
summaries = {}
for classValue, instances in separated.iteritems():
summaries[classValue] = summarize(instances)
return summaries
def calculateProbability(x, mean, stdev):
exponent = math.exp(-(math.pow(x-mean,2)/(2*math.pow(stdev,2))))
return (1 / (math.sqrt(2*math.pi) * stdev)) * exponent
def calculateClassProbabilities(summaries, inputVector):
probabilities = {}
for classValue, classSummaries in summaries.iteritems():
probabilities[classValue] = 1
for i in range(len(classSummaries)):
mean, stdev = classSummaries[i]
x = inputVector[i]
probabilities[classValue] *= calculateProbability(x, mean, stdev)
return probabilities
def predict(summaries, inputVector):
probabilities = calculateClassProbabilities(summaries, inputVector)
bestLabel, bestProb = None, -1
for classValue, probability in probabilities.iteritems():
if bestLabel is None or probability > bestProb:
bestProb = probability
bestLabel = classValue
return bestLabel
def getPredictions(summaries, testSet):
predictions = []
for i in range(len(testSet)):
result = predict(summaries, testSet[i])
predictions.append(result)
return predictions
def getAccuracy(testSet, predictions):
correct = 0
for i in range(len(testSet)):
if testSet[i][-1] == predictions[i]:
correct += 1
return (correct/float(len(testSet))) * 100.0
def main():
filename = 'pima-indians-diabetes.data.csv'
splitRatio = 0.67
dataset = loadCsv(filename)
trainingSet, testSet = splitDataset(dataset, splitRatio)
print('Split {0} rows into train={1} and test={2} rows').format(len(dataset), len(trainingSet), len(testSet))
# prepare model
summaries = summarizeByClass(trainingSet)
# test model
predictions = getPredictions(summaries, testSet)
accuracy = getAccuracy(testSet, predictions)
print('Accuracy: {0}%').format(accuracy)
main()
最后运行汇总的结果应该如下：
1. Split 72 rows into train=48 and test=24 rows
2. Accuracy: 76.3779527559%
