作业要求:https://edu.cnblogs.com/campus/gzcc/GZCC-16SE1/homework/2822
1. 下载一长篇中文小说。
下载的小说为村上春树的《且听风吟》
2. 从文件读取待分析文本。
mytext = open('yuesifengyin.txt',encoding='UTF-8').read()
3.安装并使用jieba进行中文分词。
4.更新词库,加入所分析对象的专业词汇。
jieba.add_word('哈特费尔德') jieba.add_word('约翰.F.肯尼迪') jieba.add_word('布鲁克.韦顿') words = list(jieba.cut(mytext))
5. 生成词频统计,排除语法型词汇,代词、冠词、连词等停用词
dele = {'。','!','?','的','“','”','(',')',' ','》','《',','} wordDict = {} wordSet = set(words)-dele ##去除无语义符号 for w in wordSet: if len(w)>1: wordDict[w] = words.count(w)
6. 排序
wordlist = sorted(wordDict.items(), key = lambda x:x[1], reverse = True)
7. 输出词频最大TOP20
8.把结果存放到文件里
9. 生成词云
10. 完整代码+注释
