NanoClimateFeverRetrieval

An MTEB dataset

Massive Text Embedding Benchmark

NanoClimateFever is a small version of the BEIR dataset adopting the FEVER methodology that consists of 1,535 real-world claims regarding climate-change.


Task category	t2t
Domains	Non-fiction, Academic, News
Reference	https://arxiv.org/abs/2012.00614

How to evaluate on this task

You can evaluate an embedding model on this dataset using the following code:

import mteb

task = mteb.get_tasks(["NanoClimateFeverRetrieval"])
evaluator = mteb.MTEB(task)

model = mteb.get_model(YOUR_MODEL)
evaluator.run(model)
