IMDB movie reviews
The labeled dataset consists of 5000 IMDB movie reviews, specially selected for sentiment analysis. The sentiment of the reviews is binary, meaning an IMDB rating < 5 results in a sentiment score of 0, and a rating >=7 has a sentiment score of 1. No individual movie has more than 30 reviews. Important note: we removed non ASCII symbols from the original dataset to satisfy CRAN policy.
A data frame with 5000 rows and 3 variables:
- Unique ID of each review
- Sentiment of the review; 1 for positive reviews and 0 for negative reviews
- Text of the review (UTF-8)
