Montreal Archive of Sleep Studies Dataset

The Montreal Archive of Sleep Studies (MASS) is an open-access and collaborative database of laboratory-based polysomnography (PSG) recordings O’Reilly, C., et al. (2014) J Seep Res, 23(6):628-635. Its goal is to provide a standard and easily accessible source of data for benchmarking the various systems developed to help the automation of sleep analysis. It also provides a readily available source of data for fast validation of experimental results and for exploratory analyses. Finally, it is a shared resource that can be used to foster large-scale collaborations in sleep studies.

MASS is composed of cohorts themselves comprising subsets. Recordings within subsets is kept as homogeneous as possible, whereas it is more heterogeneous between subsets. To allow inter-study comparisons, researchers validating their results on MASS are encouraged to specify which portion of the database they used in their assessment (e.g., MASS-C1 for the whole cohort 1, MASS-C1/SS1-SS3 for subsets 1, 2 and 3 of cohort 1).

Currently, the first MASS cohort available is described in O’Reilly, C., et al. (2014) J Seep Res, 23(6):628-635. This cohort comprises polysomnograms of 200 complete nights recorded in 97 men and 103 women of age varying between 18 and 76 years (mean: 38.3 years, SD: 18.9 years). It has been split into five different subsets.

蒙特利尔睡眠研究档案（MASS）是一项开放获取且协作的基于实验室的多导睡眠图（PSG）录音数据库（O’Reilly, C. 等，2014年，《睡眠研究杂志》，23(6)：628-635）。其旨在提供一项标准化且易于获取的数据资源，以供评估各类旨在辅助睡眠分析自动化的系统之基准测试。此外，它还提供了一个易于获取的数据来源，用于快速验证实验结果以及进行探索性分析。最后，MASS是一个共享资源，可用于促进睡眠研究的大规模合作。
MASS由多个群体组成，每个群体又包含子集。子集中的录音尽可能地保持同质性，而不同子集之间的异质性则较大。为了便于跨研究比较，鼓励在MASS上验证其结果的研究人员明确指出其在评估中使用的数据库部分（例如，MASS-C1代表整个第1群体，MASS-C1/SS1-SS3代表第1群体的第1、2和3个子集）。
目前，可用的第一个MASS群体由O’Reilly, C.等（2014年，《睡眠研究杂志》，23(6)：628-635）所描述。该群体包含200个完整夜晚的多导睡眠图，记录于97名男性和103名女性之间，年龄介于18至76岁（平均：38.3岁，标准差：18.9岁）。该群体已被划分为五个不同的子集。
