About UnifiedQA

UnifiedQA is an open source tool for building end-to-end question answering systems. It provides users with a comprehensive suite of components for creating powerful question-answering systems. This includes a library for pre-processing input data, a library of models for natural language understanding, and a library of models for generating answers. UnifiedQA also features a selection of evaluation metrics and data sets to help you evaluate your models.With UnifiedQA, developers of all skill levels can create custom question-answering systems quickly and easily. It provides a comprehensive set of tools, components, and resources that simplify the process of building and deploying QA systems. With its intuitive user interface, developers can quickly set up their systems and start training models. Plus, it offers easy integration with popular frameworks such as TensorFlow, PyTorch, and others.
