Starting with a paper released at NIPS 2016, MS MARCO is a collection of datasets focused on deep learning in search.

The first dataset was a question answering dataset featuring 100,000 real Bing questions and a human generated answer. Since then we released a 1,000,000 question dataset, a natural langauge generation dataset, a passage ranking dataset, keyphrase extraction dataset, crawling dataset, and a conversational search.

Passage and Document Retrieval(10/26/2018-Present)

Based on the passages and questions in the Question Answering Dataset, a passage and document ranking task was formulated. There are 8.8 million passages, 3.2 million documents and the goal is to rank based on their relevance.

Relevance labels are derived from what passages was marked as having the answer in the QnA dataset making this one of the largest relevance datasets ever.

This dataset is the focus of the 2020 and 2019 TREC Deep Learning Track and has been used as a teaching aid for ACM SIGIR/SIGKDD AFIRM Summer School on Machine Learning for Data Mining and Search.

Tasks

  1. Passage Re-Ranking:Given a candidate top 1000 passages as retrieved by BM25, re-rank passage by relevance.
  2. Passage Full Ranking:Given a corpus of 8.8m passages generate a candidate top 1000 passages sorted by relevance.
  3. Document Re-Ranking:Given a candidate top 1000 document as retrieved by BM25, re-rank documents by relevance.
  4. Document Full Ranking:Given a corpus of 3.2m documents generate a candidate top 1000 documents sorted by relevance.

KeyPhrase Extraction(10/18/2019-Present)

Keyphrase extraction on open domain document is an up and coming area that can be used for many NLP tasks like document ranking, Topic Clusetring, etc. To enable the research community to build performant KeyPhrase Extraction systems we have build OpenKP a human annotated extraction of Keyphrases on a wide variety of documents.

The dataset features 148,124 real world web documents along with a human annotation indicating the 1-3 most relevant keyphrases. More information about the dataset and our initial experiments can be found in the paper Open Domain Web Keyphrase Extraction Beyond Language Modeling which was an oral presentation at EMNLP-IJCNLP 2019. It is part of the MSMARCO dataset family and research projects like this power the core document understanding pipeline that Bing uses.

Tasks

  1. Given a document produce the top 3 most salient keyphrases

Question Answering and Natural Langauge Generation(12/01/2016-Present)

The original focus of MSMARCO was to provide a corpus for training and testing systems which given a real domain user query systems would then provide the most likley candidate answer and do so in language which was natural and conversational.

This data comes in three tasks/forms: Original QnA dataset(v1.1), Question Answering(v2.1), Natural Language Generation(v2.1). The original question answering datset featured 100,000 examples and was released in 2016. Leaderboard is now closed but data is availible below.

The current competitive tasks are Question Answering and Natural Language Generation. Question Answering features over 1,000,000 queries and is much like the original QnA dataset but bigger and with higher quality. The Natural Language Generation dataset features 180,000 examples and builds upon the QnA dataset to deliver answers that could be spoken by a smart speaker.

Tasks

  1. QnA(v1.1 now closed):Given a query and 10 candidate passages select the most relvant one and use it to answer the question.
  2. QnA(v2.1):Given a query and 10 candidate passages select the most relvant one and use it to answer the question.
  3. NLGEN(v2.1):Given a query and 10 candidate passages select the most relvant one and use it to answer the question. Provide your answer in a way in which it could be read from a smart speaker and make sense without any additional context.

Conversational Search

Truly Conversational Search is the next logic step in the journey to generate intelligent and useful AI. To understand what this may mean, researchers have voiced a continuous desire to study how people currently converse with search engines. As a result we have released a large corpus of anonymized user search sessions.

We hope the community can use this corpus to explore what conversations with search engines look like.

Tasks

  1. Given a session with a masked query and a candidate list of 1000 potential queries rerank by the most likley query

Optimal Crawling

The dataset used for Optimal Freshness Crawl Under Politeness Constraints and Staying up to Date with Online Content Changes Using Reinforcement Learning for Scheduling which are both focused on providing an optimal crawling schedule for a search engine based ont he changing nature of the internet.

There is currently no public task associated with this dataset

MS MARCO Submission Instructions

Once you have built a model that meets your expectations on evaluation with the dev set, you can submit your test results to get official evaluation on the test set. To ensure the integrity of the official test results, we do not release the correct answers for test set to the public. To submit your model for official evaluation on the test set, follow the below steps:

  1. Generate your candidate output for the dev set.
  2. Run the official evaluation methodologies found in the task specific git repo and verify your systems are running as expected
  3. Generate your candidate output for the eval/test set and submit the following information by

Your email should include

  1. Candidate evaluation file
  2. Candidate dev file
  3. Individual/Team Name: Name of the individual or the team to appear in the leaderboard [Required]
  4. Individual/Team Institution: Name of the institution of the individual or the team to appear in the leaderboard [Optional]
  5. Model code: Training code for the model [Recommended]
  6. Model information: Name of the model/technique to appear in the leaderboard [Required]
  7. Paper Information: Name, Citation, URL of the paper if model is from a published work to appear in the leaderboard [Optional]

To avoid "P-hacking" we discourage too many submissions from the same group in a short period of time.

About MS MARCO

Microsoft Machine Reading Comprehension (MS MARCO) is a collection of large scale datasets for deep learning related to Search. In MS MARCO, all questions are sampled from real anonymized user queries. The context passages, from which answers in the dataset are derived, are extracted from real web documents using the most advanced version of the Bing search engine. The answers to the queries are human generated if they could summarize the answer.
