| The LongForm dataset is created by leveraging English corpus examples with augmented instructions. We select a diverse set of human-written documents from existing corpora such as C4 and Wikipedia and generate instructions for the given documents via LLMs. Then, we extend these examples with structured corpora examples such as Stack Exchange and WikiHow and task examples such as question answering, email writing, grammar error correction, story/poem generation, and text summarization. | |
| **Paper**: https://arxiv.org/abs/2304.08460 | |
| **Dataset and Models**: https://github.com/akoksal/LongForm | |
| **Tips**: | |
| 1. Use the "[EOI]" token at the end of the instruction for OPT models. This demo adds [EOI] automatically if you forget it. | |
| 2. The LongForm dataset and models mainly focus on long text generation and have limitations regarding structured prediction tasks in NLP. | |
