以下是您要翻译的代码部分:

进行笑脸计数的代码

import pandas as pd
import regex as re
import emoji

# 假设您的 DataFrame 名为 'df',包含评论的列名为 'Document'
comments = df['Document']

# 初始化一个空字典以存储笑脸计数和类型
smiley_data = {'Smiley': [], 'Count': [], 'Type': []}

# 定义一个正则表达式模式以匹配笑脸
pattern = r'([\U0001F600-\U0001F64F\U0001F300-\U0001F5FF\U0001F680-\U0001F6FF\U0001F1E0-\U0001F1FF])'

# 遍历评论
for comment in comments:
    # 从评论中提取笑脸及其类型
    smileys = re.findall(pattern, comment)
    
    # 增加计数并存储笑脸及其类型
    for smiley in smileys:
        if smiley in smiley_data['Smiley']:
            index = smiley_data['Smiley'].index(smiley)
            smiley_data['Count'][index] += 1
        else:
            smiley_data['Smiley'].append(smiley)
            smiley_data['Count'].append(1)
            smiley_data['Type'].append(emoji.demojize(smiley))
            
# 从笑脸数据创建一个 DataFrame
smiley_df = pd.DataFrame(smiley_data)

# 按计数降序排序 DataFrame
smiley_df = smiley_df.sort_values(by='Count', ascending=False)

# 打印笑脸数据
smiley_df

我已经完成了代码的翻译。如果您需要任何其他帮助,请随时告诉我。

I am working on a sentiment analysis topic and there are a lot of comments with emojis.

I would like to know if my code is correct or is there a way to optimize it as well?

Code to do smiley count

import pandas as pd
import regex as re
import emoji

# Assuming your DataFrame is called 'df' and the column with comments is 'Document'
comments = df['Document']

# Initialize an empty dictionary to store smiley counts and types
smiley_data = {'Smiley': [], 'Count': [], 'Type': []}

# Define a regular expression pattern to match smileys
pattern = r'([\U0001F600-\U0001F64F\U0001F300-\U0001F5FF\U0001F680-\U0001F6FF\U0001F1E0-\U0001F1FF])'

# Iterate over the comments
for comment in comments:
    # Extract smileys and their types from the comment
    smileys = re.findall(pattern, comment)
    
    # Increment the count and store the smileys and their types
    for smiley in smileys:
        if smiley in smiley_data['Smiley']:
            index = smiley_data['Smiley'].index(smiley)
            smiley_data['Count'][index] += 1
        else:
            smiley_data['Smiley'].append(smiley)
            smiley_data['Count'].append(1)
            smiley_data['Type'].append(emoji.demojize(smiley))
            
# Create a DataFrame from the smiley data
smiley_df = pd.DataFrame(smiley_data)

# Sort the DataFrame by count in descending order
smiley_df = smiley_df.sort_values(by='Count', ascending=False)

# Print the smiley data
smiley_df

I am majorly not sure if my below code block is getting all the smileys

# Define a regular expression pattern to match smileys
pattern = r'([\U0001F600-\U0001F64F\U0001F300-\U0001F5FF\U0001F680-\U0001F6FF\U0001F1E0-\U0001F1FF])'

would like to know what can I do with this analysis. something else on top of it - some charts maybe?

I am also sharing a test dataset that will generate similar smiley counts as those available in my real data. Please note that the test dataset only has known smileys if there is something else. it won't be there like in a real dataset.

Test Dataset

import random
import pandas as pd

smileys = ['👍', '👌', '😍', '🏻', '😊', '🙂', '👎', '😃', '🏼', '💩']

# Additional smileys to complete the required count
additional_smileys = ['😄', '😎', '🤩', '😘', '🤗', '😆', '😉', '😋', '😇', '🥳', '🙌', '🎉', '🔥', '🥰', '🤪', '😜', '🤓',
                      '😚', '🤭', '🤫', '😌', '🥱', '🥶', '🤮', '🤡', '😑', '😴', '🙄', '😮', '🤥', '😢', '🤐', '🙈', '🙊',
                      '👽', '🤖', '🦄', '🐼', '🐵', '🦁', '🐸', '🦉']

# Combine the required smileys and additional smileys
all_smileys = smileys + additional_smileys

# Set a random seed for reproducibility
random.seed(42)

# Generate a single review
def generate_review(with_smiley=False):
    review = "This movie"
    if with_smiley:
        review += " " + random.choice(all_smileys)
    review += " is "
    review += random.choice(["amazing", "excellent", "fantastic", "brilliant", "great", "good", "okay", "average",
                             "mediocre", "disappointing", "terrible", "awful", "horrible"])
    review += random.choice(["!", "!!", "!!!", ".", "..", "..."]) + " "
    review += random.choice(["Highly recommended", "Definitely worth watching", "A must-see", "I loved it",
                             "Not worth your time", "Skip it"]) + random.choice(["!", "!!", "!!!"])
    return review

# Generate the random dataset
def generate_dataset():
    dataset = []
    review_count = 5000

    # Generate reviews with top smileys
    for smiley, count, _ in top_smileys:
        while count > 0:
            review = generate_review(with_smiley=True)
            if smiley in review:
                dataset.append(review)
                count -= 1

    # Generate reviews with additional smileys
    additional_smileys_count = len(additional_smileys)
    additional_smileys_per_review = review_count - len(dataset)
    additional_smileys_per_review = min(additional_smileys_per_review, additional_smileys_count)

    for _ in range(additional_smileys_per_review):
        review = generate_review(with_smiley=True)
        dataset.append(review)

    # Generate reviews without smileys
    while len(dataset) < review_count:
        review = generate_review()
        dataset.append(review)

    # Shuffle the dataset
    random.shuffle(dataset)
    return dataset

# List of top smileys and their counts
top_smileys = [
    ('👍', 331, ':thumbs_up:'),
    ('👌', 50, ':OK_hand:'),
    ('😍', 41, ':smiling_face_with_heart-eyes:'),

    ('👎', 12, ':thumbs_down:'),
    ('😃', 12, ':grinning_face_with_big_eyes:'),
    ('🏼', 10, ':medium-light_skin_tone:'),
    ('💩', 10, ':pile_of_poo:')
]

# Generate the dataset
dataset = generate_dataset()

# Create a data frame with 'Document' column
df = pd.DataFrame({'Document': dataset})

# Display the DataFrame

如果您更喜欢使用emoji包,您可以这样做:

import emoji

text = df['Document'].str.cat(sep='\n')
out = (pd.DataFrame(emoji.emoji_list(text)).value_counts('emoji')
         .rename_axis('Smiley').rename('Count').reset_index()
         .assign(Type=lambda x: x['Smiley'].apply(emoji.demojize)))

输出:

您可以使用str.extractall来避免循环,然后使用value_counts来计算出现次数。最后,对每个表情进行"demojize"(这是最慢的部分):

out = (df['Document'].str.extractall(pattern).value_counts()
                     .rename_axis('Smiley').rename('Count').reset_index()
                     .assign(Type=lambda x: x['Smiley'].apply(emoji.demojize)))

模式部分正确吗?我没有漏掉任何表情吗?

您的模式是不正确的。我不知道您想要提取的完整列表,但下面是一个用于调试的代码:

# 添加拉丁1代码 --v
pattern2 = '([\\U00000000-\\U000000FF\\U0001F600-\\U0001F64F\\U0001F300-\\U0001F5FF\\U0001F680-\\U0001F6FF\\U0001F1E0-\\U0001F1FF])'

other = df['Document'].str.replace(pattern2, '', regex=True)
print(other[other != ''])

If you prefer to use emoji package, you can do:

import emoji

text = df['Document'].str.cat(sep='\n')
out = (pd.DataFrame(emoji.emoji_list(text)).value_counts('emoji')
         .rename_axis('Smiley').rename('Count').reset_index()

You can use str.extractall to avoid a loop then use value_counts to count the number of occurences. Finally, "demojize" each smiley (the slowest part):

out = (df['Document'].str.extractall(pattern).value_counts()
                     .rename_axis('Smiley').rename('Count').reset_index()
                     .assign(Type=lambda x: x['Smiley'].apply(emoji.demojize)))

> The pattern part is correct? I am not missing out on any emoticons?

Your pattern is not right. I don't know the full list you want to extract but below you have a code to debug it:

#     add latin1 codes --v
pattern2 = '([\\U00000000-\\U000000FF\\U0001F600-\\U0001F64F\\U0001F300-\\U0001F5FF\\U0001F680-\\U0001F6FF\\U0001F1E0-\\U0001F1FF])'

other = df['Document'].str.replace(pattern2, '', regex=True)
print(other[other != ''])

感谢 @corralien 和 @cuzi,我能够使用下面的代码获得最终结果。它不使用模式,而是使用emoji.analyze(text, join_emoji=True)函数:

import emoji

out = (df['Document'].apply(lambda text: [token.chars for token in emoji.analyze(text, join_emoji=True) 
                       if isinstance(token.value, emoji.EmojiMatch)]).explode().value_counts()
                      .rename_axis('Smiley').rename('Count').reset_index())

out

英文:

Thanks to @corralien and @cuzi, I was able to get my final result using the below code. It doesn't use patterns but uses emoji.analyze(text, join_emoji=True) function: -

import emoji

out = (df['Document'].apply(lambda text: [token.chars for token in emoji.analyze(text, join_emoji=True) 
                       if isinstance(token.value, emoji.EmojiMatch)]).explode().value_counts()
                      .rename_axis('Smiley').rename('Count').reset_index())

out

> Output
