Sentiment analysis, also known as opinion mining, is a natural language processing (NLP) technique used to determine and categorize the emotional tone or sentiment expressed in a piece of text, such as a review, social media post, or news article. The goal of sentiment analysis is to assess whether the text conveys a positive, negative, or neutral sentiment, and sometimes to quantify the intensity of that sentiment.

Key components of sentiment analysis include:
|
16 |
+
|
17 |
+
1. **Text Data:** Sentiment analysis typically starts with a body of text, which can range from short messages like tweets to longer documents like product reviews.
|
18 |
+
|
19 |
+
2. **Preprocessing:** Text data is often cleaned and processed to remove noise, such as punctuation and stopwords, and to convert words to a common format (e.g., lowercase).
|
20 |
+
|
21 |
+
3. **Sentiment Classification:** Sentiment analysis algorithms use various techniques, including machine learning and lexicon-based approaches, to classify text into sentiment categories. Machine learning models are trained on labeled data to predict sentiment labels (positive, negative, neutral) for unseen text.
|
22 |
+
|
23 |
+
4. **Sentiment Scores:** Some sentiment analysis tools provide sentiment scores that quantify the degree of sentiment intensity. For example, a positive sentiment might have a higher score for very positive text and a lower score for mildly positive text.
|
24 |
+
|
25 |
+
Applications of sentiment analysis are diverse and include:
|
26 |

29 |
