推文的情绪分析

Question

tweets = [
    "Wow, what a great day today!! #sunshine",
    "I feel sad about the things going on around us. #covid19",
    "I'm really excited to learn Python with @JovianML #zerotopandas",
    "This is a really nice song. #linkinpark",
    "The python programming language is useful for data science",
    "Why do bad things happen to me?",
    "Apple announces the release of the new iPhone 12. Fans are excited.",
    "Spent my day with family!! #happy",
    "Check out my blog post on common string operations in Python. #zerotopandas",
    "Freecodecamp has great coding tutorials. #skillup"
]


happy_words = ['great', 'excited', 'happy', 'nice', 'wonderful', 'amazing', 'good', 'best']

sad_words = ['sad', 'bad', 'tragic', 'unhappy', 'worst']

我无法使用循环找到中性推文，有人可以帮我吗？

Answer 1

以下代码可直接用于分析每个给定文本中的情绪。 它可能提供任务的概念。

tweets = [ "Wow, what a great day today!! #sunshine", "I feel sad about the things going on around us. #covid19", "I'm really excited to learn Python with @JovianML #zerotopandas", "This is a really nice song. #linkinpark", "The python programming language is useful for data science", "Why do bad things happen to me?", "Apple announces the release of the new iPhone 12. Fans are excited.", "Spent my day with family!! #happy", "Check out my blog post on common string operations in Python. #zerotopandas", "Freecodecamp has great coding tutorials. #skillup" ]
happy_words = ['great', 'excited', 'happy', 'nice', 'wonderful', 'amazing', 'good', 'best']
sad_words = ['sad', 'bad', 'tragic', 'unhappy', 'worst']

def analyze(text, pos_words, neg_words):
    score = 0
    score += sum(1 for word in pos_words if word in text)
    score += sum(-1 for word in neg_words if word in text)

    if score > 0:
        sentiment = "positive"
    elif score < 0:
        sentiment = "negative"
    else:
        sentiment = "neutral"
    
    return sentiment

for text in tweets:
    sentiment = analyze(text, happy_words, sad_words)
    print(f"tweet: {text}")
    print(f"sentiment: {sentiment}")
    print()

Output：

sentiment: negative

tweet: I'm really excited to learn Python with @JovianML #zerotopandas
