ir_datasets: TREC CAsT (Conversational Assistance)To use version 0 of the corpus, you need a copy of the Washington Post Collection, provided by NIST.
Your organization may already have a copy. If this is the case, you may only need to complete a new "Individual Argeement". Otherwise, your organization will need to file the "Organizational agreement" with NIST. It can take some time to process, but you will end up with a password-protected download link.
For the v0 corpus, the source file required is WashingtonPost.v2.tar.gz. ir_datasets expects the above file to be copied/linked under ~/.ir_datasets/wapo/WashingtonPost.v2.tar.gz.
The TREC Conversational Assistance Track (CAsT) is a benchmark for Conversational Information Seeking (CIS) models.
Version 0 of the TREC CAsT corpus. This version uses documents from the Washington Post (version 2), TREC CAR (version 2), and MS MARCO passage (version 1).
This corpus was originally meant to be used for evaluation of the 2019 task, but the Washington Post corpus was not included for scoring in the final version due to "an error in the process led to ambiguous document ids," and Washington Post documents were removed from participating systems. As such, trec-cast/v1 (which doesn't include the Washington Post) should be used for the 2019 version of the task. However, this version still can be used for the training set (trec-cast/v0/train) or for replicating the original submissions to the track (prior to the removal of Washingotn Post documents).

Relevance levels
| Rel. | Definition | Count | % |
|---|---|---|---|
| 0 | Fails to meet. The passage is not relevant to the question. The passage is unrelated to the target query. | 34K | 83.5% |
| 1 | Slightly meets. The passage includes some information about the turn, but does not directly answer it. Users will find some useful information in the passage that may lead to the correct answer, perhaps after additional rounds of conversation (better than nothing). | 2.7K | 6.7% |
| 2 | Moderately meets. The passage answers the turn, but is focused on other information that is unrelated to the question. The passage may contain the answer, but users will need extra effort to pick the correct portion. The passage may be relevant, but it may only partially answer the turn, missing a small aspect of the context. | 1.8K | 4.5% |
| 3 | Highly meets. The passage answers the question and is focused on the turn. It would be a satisfactory answer if Google Assistant or Alexa returned this passage in response to the query. It may contain limited extraneous information. | 1.4K | 3.5% |
| 4 | Fully meets. The passage is a perfect answer for the turn. It includes all of the information needed to fully answer the turn in the conversation context. It focuses only on the subject and contains little extra information. | 731 | 1.8% |
