A score of 55% and above indicates high-quality translation pairs, even if the first version of the model we developed gave them such a score. We will try to release a newer model in the future with better quality and consistently fast scoring speeds, and release it to the public once we decide… See the full description on the dataset page: https://huggingface.co/datasets/cloverx-id/lumi-repository-parallel-en-id-corpus.human-ai-parallel-corpus
Human-AI Parallel English Corpus (HAP-E) 🙃
Purpose
The HAP-E corpus is designed for comparisions of the writing produced by humans and the writing produced by large language models (LLMs).
The corpus was created by seeding an LLM with an approximately 500-word chunk of human-authored text and then prompting the model to produce an additional 500 words.
Thus, a second 500-word chunk of human-authored text (what actually comes next in the original text) can be compared to… See the full description on the dataset page: https://huggingface.co/datasets/browndw/human-ai-parallel-corpus.Egyptian-Arabic-English-Parallel-Corpus

Introduction
This is a LLM-filtered set of the first 1M rows from ntt's JParaCrawl v3 large English-Japanese parallel corpus.
The original JParaCrawl corpus was put together by automated means - aligning Japanese texts with their apparent English translations that were found in-the-wild, on the internet.
Whilst manually browsing the original data, I noticed that there were obvious quality issues that made me anxious about using the dataset at all.
