Hi David,

yes, well observed:) It is true that the relevance of documents is only judged by a single label: 1 if the document appears to be a corresponding answer to the question/query in an FAQ page, which we extracted from a web crawl dump. We know that these kind of "sparse relevance judgment" is in some sense suboptimal, yet for now we live with it, as it is a common practice in many IR datasets.

Hence, we could simply omit the "score" column. The reason why we nevertheless kept the "score" column in the qrels data splits, is to use the exact same format as in other datasets that serve as MTEB Retrieval task, e.g. SciFact. Besides streamlining the formatting, as I said, there is no deeper motivation.

Best regards
Michael
