Dataset Summary

This is the wikipedia split used to evaluate the Dense Passage Retrieval (DPR) model. It contains 21M passages from wikipedia along with their DPR embeddings. The wikipedia articles were split into multiple, disjoint text blocks of 100 words as passages.

The wikipedia dump is the one from Dec. 20, 2018.

There are two types of DPR embeddings based on two different models:

nq: the model is trained on the Natural Questions dataset
multiset: the model is trained on multiple datasets

Additionally, a FAISS index can be created from the embeddings:

exact: with an exact FAISS index (high RAM usage)
compressed: with a compressed FAISS index (approximate, but lower RAM usage)
no_index: without FAISS index

Finally, there is the possibility of generating the dataset without the embeddings:

no_embeddings

Data Instances

Each instance contains a paragraph of at most 100 words, as well as the title of the wikipedia page it comes from, and the DPR embedding (a 768-d vector).
