The Twitter Sentiment Analysis Dataset contains 1,578,627 classified tweets, each row is marked as 1 for positive sentiment and 0 for negative sentiment.
|
| 37 |
+
The dataset is based on data from the following two sources:
|
| 38 |
+
|
| 39 |
+
University of Michigan Sentiment Analysis competition on Kaggle
|
| 40 |
+
Twitter Sentiment Corpus by Niek Sanders
|
| 41 |
+
|
| 42 |
+
Finally, I randomly selected a subset of them, applied a cleaning process, and divided them between the test and train subsets, keeping a balance between
|
| 43 |
+
the number of positive and negative tweets within each of these subsets.
