Asking a clarification has also been recognized as a major component in conversational information seeking systems. MIMICS is a collection of search clarification datasets for real search queries sampled from the Bing query logs. Each clarification in MIMICS consists of a clarifying question and up to five candidate answers. Here is an example:

MIMICS contains three datasets:

• MIMICS-Click includes over 400k unique queries, their associated clarification panes, and the corresponding aggregated user interaction signals (i.e., clicks).
• MIMICS-ClickExplore is an exploration data that includes aggregated user interaction signals for over 60k unique queries, each with multiple clarification panes.
• MIMICS-Manual includes over 2k unique real search queries. Each query-clarification pair in this dataset has been manually labeled by at least three trained annotators. It contains graded quality labels for the clarifying question, the candidate answer set, and the landing result page for each candidate answer.

MIMICS enables researchers to study a number of tasks related to search clarification, including clarification generation and selection, user engagement prediction for clarification, click models for clarification, and analyzing user interactions with search clarification. For more information, refer to the following paper:

The datasets are released in a tab-separated file format (TSV), with the header in the first row of each file. The column descriptions are given below. For more detail, refer to the paper mentioned above.

To enable researchers to use the web search result page (SERP) information, we have also released the search results returned by the Bing's Web Search API for all the queries in the MIMICS datasets. The SERP data can be downloaded from here (3.2GB compressed, 16GB decompressed). Each line in the file can be loaded as a JSON object and contain all information returned by the Bing's Web Search API.
