| # bert-base-multilingual-uncased-sentiment | |
| This a bert-base-multilingual-uncased model finetuned for sentiment analysis on product reviews in six languages: English, Dutch, German, French, Spanish and Italian. It predicts the sentiment of the review as a number of stars (between 1 and 5). | |
| This model is intended for direct use as a sentiment analysis model for product reviews in any of the six languages above, or for further finetuning on related sentiment analysis tasks. | |
| ## Training data | |
| Here is the number of product reviews we used for finetuning the model: | |
| | Language | Number of reviews | | |
| | -------- | ----------------- | | |
| | English | 150k | | |
| | Dutch | 80k | | |
| | German | 137k | | |
| | French | 140k | | |
| | Italian | 72k | | |
| | Spanish | 50k | | |
| ## Accuracy | |
| The finetuned model obtained the following accuracy on 5,000 held-out product reviews in each of the languages: | |
| - Accuracy (exact) is the exact match on the number of stars. | |
| - Accuracy (off-by-1) is the percentage of reviews where the number of stars the model predicts differs by a maximum of 1 from the number given by the human reviewer. | |
| | Language | Accuracy (exact) | Accuracy (off-by-1) | | |
| | -------- | ---------------------- | ------------------- | | |
| | English | 67% | 95% | |
| | Dutch | 57% | 93% | |
| | German | 61% | 94% | |
| | French | 59% | 94% | |
| | Italian | 59% | 95% | |
| | Spanish | 58% | 95% | |
