2.1 任务说明

任务主题：论⽂文作者统计，统计所有论⽂文作者出现频率Top10的姓名；
任务内容：论⽂文作者的统计、使⽤用 Pandas 读取数据并使⽤用字符串操作；
任务成果：学习 Pandas 的字符串串操作；

2.2 数据处理理步骤

在原始arxiv数据集中论⽂文作者authors 字段是⼀个字符串格式，其中每个作者使用逗号进行分隔，所
以我们⾸先需要完成以下步骤：

使⽤用逗号对作者进⾏切分；
剔除单个作者中⾮常规的字符；
具体操作可以参考以下例子：

'''
C. Bal\\'azs, E. L. Berger, P. M. Nadolsky, C.-P. Yuan
# 切分为，其中\\为转义符
C. Ba'lazs
E. L. Berger
P. M. Nadolsky
C.-P. Yuan
'''
#当然在原始数据集中authors_parsed 字段已经帮我们处理理好了了作者信息，可以直接使⽤用该字段完成后续统计。

"\nC. Bal\\'azs, E. L. Berger, P. M. Nadolsky, C.-P. Yuan\n# 切分为，其中\\为转义符\nC. Ba'lazs\nE. L. Berger\nP. M. Nadolsky\nC.-P. Yuan\n"

2.3 字符串串处理理

在Python中字符串是最常用的数据类型，可以使用引号('或")来创建字符串串。Python中所有的字符都使
用字符串存储，可以使⽤方括号来截取字符串，如下实例：

var1 = 'Hello Datawhale!'
var2 = "Python Everwhere!"
print("var1[-10:]: ", var1[-10:])
print("var2[1:5]: ", var2[0:7])

var1[-10:]:  Datawhale!
var2[1:5]:  Python

Python中还内置了很多内置函数，非常方便使用：

string.capitalize() 把字符串的第一个字符大写
string.isalpha() 如果 string 至少有一个字符并且所有字符都是字母则返回 True,否则返回False
string.title() 每个单词首字母大写
string.upper()转换 string 中的小写字母为大写

2.4 具体代码实现以及讲解

2.4.1 数据读取

import os
os.getcwd()

'C:\\Users\\Administrator\\Desktop\\datawhale\\数据分析之学术前沿分析'

data = []
import pandas as pd
import json
with open('./arxiv-metadata-oai-2019.json/arxiv-metadata-oai-2019.json','r' ) as f:for idx, line in enumerate(f):d = json.loads(line)d = {"authors": d["authors"],'categories': d['categories'],'authors_parsed': d['authors_parsed'] }data.append(d)data = pd.DataFrame(data)# 为了方便处理数据，我们只选择了三个字段进行读取。

2.4.2 数据统计

统计所有作者姓名出现频率的Top10；
统计所有作者姓（姓名最后一个单词）的出现频率的Top10；
统计所有作者姓第⼀个字符的评率；
为了了节约计算时间，下面选择部分类别下的论文进行处理理：

# 选择类别为cs.CV下⾯面的论⽂文
data2 = data[data['categories'].apply(lambda x: 'cs.CV' in x)]
# 拼接所有作者
