The Babel Sentiment Project uses a simple 3-label codebook with the classical negative, neutral, and positive labels, corresponding to the information available at poltextlab/EngEmBERT3 models HuggingFace model card.

The model was prepared to make predictions on sentence-level data, meaning you should provide input that is segmented into sentences in order to achieve optimal performance. If you are intending to submit data to the NER Babel Machine, we recommend submitting your data there first, as the processed file will be split into sentences, making it a suitable dataset for the Sentiment Babel Machine. The Sentiment Babel Machine currently uses a pooled model, that was trained on data in the following languages: Czech, English, French, German, Hungarian and Italian, but we encourage you to also submit datasets not covered under this list, as results may be useful for additional languages due to the nature of large language models.

You can upload your datasets here for automated sentiment coding. If you wish to submit multiple datasets one after another, please wait 5-10 minutes between each of your submissions. There are two possibilities for upload: pre-coded datasets or non-coded datasets. The explanation of the form and the dataset requirement is available here.

The upload requires you to fill the following form on metadata regarding the dataset. Please upload your dataset, and in case of a pre-coded dataset, if available, please attach the codebook used beside the dataset.

The non-coded datasets should contain an id and a text column. The column names must be in row 1. You are free to add supplementary variables to the dataset beyond the compulsory ones in the columns following them.

Pre-coded datasets must contain the following columns: id, text, label. The column names must be in row 1. Uploading a pre-coded sample is optional, but it can help us with calculating performance metrics and fine-tuning the language model behind MANIFESTO Babel Machine. The detailed rules of validations are available here. The mandatory data format of label is numeric(integer), based on the following:

  • 0: Negative
  • 1: No sentiment or Neutral sentiment
  • 2: Positive
You are free to add supplementary variables to the dataset beyond the compulsory ones in the columns following them. Automatic processing requires to follow these rules.

After you upload your dataset and your file is successfully processed, you will receive the sentiment-coded dataset and a file (in CSV format) that includes the predictions by the poltextlab/EngEmBERT3 model.
If the files you would like to upload are larger than 1 GB, please reach out to us with the download link attached (such as Dropbox or Google Drive) using our contact form.

If you have any questions or feedback regarding the Babel Machine, please let us know using our contact form. Please keep in mind that we can only get back to you on Hungarian business days.

Submit a dataset:

The non-coded datasets should contain an id and text column. The column names must be in row 1. You are free to add supplementary variables to the dataset beyond the compulsory ones in the columns following them. All datasets must be uploaded in a CSV file format with UTF-8 encoding.


    If you are experiencing problems with the upload form, or your submission returns an error message (particularly "Something unexpected happened during upload. Please try again later."), please try performing the following steps:

    • If you use an adblocker browser extension, please turn it off for our site. Adblockers may interfere with legitimate functionality, such as the dropdowns on the upload form. (We do not serve ads on the site.)
    • Try turning off your VPN.
    • Try submitting your data from another browser, preferably with default settings.

    If you are still receiving the "Something unexpected..." error message, please get in touch with us via our email address or the contact form. Try to add as much information as possible, e.g., what browser you are using, notable browser extensions, whether you are using a VPN or not, and exactly how you tried to submit the data (for example, you filled out everything but waited 10 minutes before pressing submit).

    The research was supported by the Ministry of Innovation and Technology NRDI Office within the RRF-2.3.1-21-2022-00004 Artificial Intelligence National Laboratory project and received additional funding from the European Union's Horizon 2020 program under grant agreement no 101008468. We also thank the Babel Machine project and HUN-REN Cloud (Héder et al. 2022; for their support.
