三国演义人物出场顺序统计(文本词频统计)

1.使用jieba库 对中文文本进行分词
2.使用字典表达词频
（与hamlet案例相似）

import jieba
txt = open("threekingdoms.txt","r",encoding="utf-8").read()
words = jieba.lcut(txt)
counts = {}
for word in words:
    if len(word) == 1:
        continue
    else:
        counts[word] = counts.get(word,0)+1
items = list(counts.items())
items.sort(key = lambda y:y[1],reverse = True)
for i in range(15):
    word , count = items[i]
    print("{}{}".format(word,count))

但是结果…

优化–>扩展程序

设置额外的库对非人名词汇进行删除（不断尝试优化），对统一含义名称进行统一

import jieba
txt = open("threekingdoms.txt","r",encoding="utf-8").read()
words = jieba.lcut(txt)
excludes = {"将军","却说","荆州","二人","不可","不能","如何","如此",
			"主公","商议","军士","左右","引兵","于是","今日","军马",
			"次日","天下","东吴","大喜"}
counts = {}
for word in words:
    if len(word) == 1:
        continue
    elif word =="诸葛亮" or word =="孔明曰":
        rword = "孔明"
    elif word =="关公" or word =="云长":
        rword = "关羽"
    elif word =="玄德" or word =="玄德曰" :
        rword = "刘备"
    elif word =="孟德" or word =="丞相":
        rword = "曹操"
    else:
        rword = word
    counts[rword] = counts.get(rword,0)+1
for word in excludes:
    del counts[word]
items = list(counts.items())
items.sort(key = lambda y:y[1],reverse = True)
for i in range(8):
    word , count = items[i]
    print("{}{}".format(word,count))
