create a python program to analyse sentiments in a text file
The process of sentiment analysis using VADER model can be described as follows:
- Read the input text: The first step is to read the input text. This can be done using a variety of methods, such as reading a file, receiving input from a user, or scraping text from a website.
- Clean the text: Once the text has been read, it is important to clean it. This involves removing any punctuation, stop words, or other noise that could interfere with the sentiment analysis process.
- Calculate the sentiment scores: The next step is to calculate the sentiment scores for the text. This is done by using a sentiment analysis model, such as VADER.
- Interpret the results: The final step is to interpret the results of the sentiment analysis. This involves understanding the meaning of the sentiment scores and how they relate to the text.
VADER is a lexicon- and rule-based sentiment analysis tool that is specifically designed to work with social media text. It is a free and open-source tool that can be used to analyze text in a variety of languages. VADER is a popular choice for sentiment analysis because it is easy to use and produces accurate results.
import pandas as pd
import vaderSentiment as vs
df = pd.read_excel('output.xlsx')
analyzer = vs.vaderSentiment.SentimentIntensityAnalyzer()
sentiment_scores = []
for text in df['Text']:
sentiment_scores.append(analyzer.polarity_scores(text))
texts = list(df['Text'])
for text, sentiment_score in zip(texts, sentiment_scores):
print("\n\nText:", text)
print("Positive:", sentiment_score['pos'])
print("Negative:", sentiment_score['neg'])
print("Neutral:", sentiment_score['neu'])
print("Compound:", sentiment_score['compound'])
Thus the python program to analyse sentiments has been implemented successfully
