Tools and Datasets

Welcome to our "Tools and Datasets" section, where you'll find an updating list of open-source tools and datasets available for free under the GNU license. Our collection of resources is designed to support researchers, developers, and data enthusiasts in pursuing innovation and discovery. Feel free to browse, download, and contribute to these valuable assets.

heBERT_logo_edited_edited.png

A Pre-trained BERT for Polarity Analysis and Emotion Recognition.

Dataset: we collected Israeli news site comments, and labeled sentiment and emotion conveyed in the comments. The data is available in this link.
 

A Hebrew version of our paper is now available here. The paper also features a tutorial on sentiment analysis and emotion detection in Hebrew.

Judicial system

A preliminary BERT model for Hebrew legal and legislative domains.

Dataset: we made part of our dataset available for public use in this link.

We are currently in the process of collecting and annotating more legal documents! You can find more here. If you wish to join us, please contact us via email.

The recordings of the legal language analysis symposium that took place on June 15th, 2023 have been uploaded to YouTube. Check them out at this link!

RHML.png

Fusion is a software system designed to facilitate Reciprocal Human-Machine Learning (RHML), specifically tailored for text classification tasks. This innovative platform enables a symbiotic relationship between humans and machines, allowing each to learn from the other to improve overall performance and accuracy in classifying texts.

Stay tuned! We are currently working on the second generation on Fusion, and on multiple projects that utilize the RHML framework. 

Recent articles:
See our article in Globes that explains the risks of keeping humans out of the learning loop here
New: See our Hebrew publications of how we used RHML to understand online Jihadist influence here
