Dataset Summary

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. All questions have been generated from real anonymized Bing user queries which grounds the dataset in a real world problem and can provide researchers real contrainsts their models might be used in. The context passages, from which the 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.

Data Fields

• query_id: a unique id for each query that is used in evaluation
• query: a unique query based on initial Bing usage
• passages: a list of 10 passages (passage_text), URLs (url), and an annotation if they were used to formulate the answer (is_selected)
• query_type: a basic division of queries based on a trained classifier (LOCATION,NUMERIC,PERSON,DESCRIPTION,ENTITY)
• answers: a list of "well-formed" answers generated by human annotators using natural language

Dataset Creation

Curation Rationale

What is the differences between MSMARCO and other MRC datasets?

• Real questions: All questions have been sampled from real anonymized bing queries.
• Real Documents: Most of the URLs that the passages were sourced from contain the full web documents (passages).
• Human Generated Well-Formed Answers: All questions have an answer written by a human in natural language.

Annotations

Annotation process

The MSMARCO dataset is generated by a well oiled pipeline optimized for the highest quality examples. The general process runs as follows:

1. Bing logs are sampled, filtered and anonymized to make sure the queries are both useful to the research community and respectful to bing users and fans.
2. Using the sampled and anonymized queries Bing generates the 10 most relevant passages for the query.
3. Highly trained judges read the query and its related passages and if there is an answer present, the supporting passages are annotated and a natural language answer is generated.
4. A smaller proportion of queries(~17% of overall dataset with 182,887 unique queries) are then passed on to a second round of judges who are asked to verify the answer is correct and rewrite(if possible) the query to be a well formed answer. These answers are designed to be understood without perfect context and are designed with smart speakers/digital assistants in mind.
