The Predicting Media Memorability task in the MediaEval evaluation campaign has been running annually since 2018 and several different tasks and data sets have been used in this time. This has allowed us to compare the performance of many memorability prediction techniques on the same data and in a reproducible way and to refine and improve on those techniques. The resources created to compute media memorability are now being used by researchers well beyond the actual evaluation campaign. In this paper we present a summary of the task, including the collective lessons we have learned for the research community.

This paper describes the 5th edition of the Predicting Video Memorability Task as part of MediaEval2022. This year we have reorganised and simplified the task in order to lubricate a greater depth of inquiry. Similar to last year, two datasets are provided in order to facilitate generalisation, however, this year we have replaced the TRECVid2019 Video-to-Text dataset with the VideoMem dataset in order to remedy underlying data quality issues, and to prioritise short-term memorability prediction by elevating the Memento10k dataset as the primary dataset. Additionally, a fully fledged electroencephalography (EEG)-based prediction sub-task is introduced. In this paper, we outline the core facets of the task and its constituent sub-tasks; describing the datasets, evaluation metrics, and requirements for participant submissions.

本文介绍了预测媒体难忘性的Mediaeval 2021，这是今年第4版的任务，因为短期和长期视频难忘性的预测仍然是一个具有挑战性的任务。在2021年，使用两个视频数据集：第一，TRECVID 2019视频到文本数据集的子集;其次，Memento10K数据集是为了提供探索交叉数据集泛化的机会。另外，介绍了基于脑电图（EEG）的预测导频子任务。在本文中，我们概述了任务的主要方面，并描述了参与者提交的数据集，评估指标和要求。

使用公共可用链路的集合，平均每周6秒的视频剪辑，每次，1,275用户多次手动注释每个视频，以指示视频的长期和短期难忘性。注释作为在线记忆游戏的一部分，并测量了参与者在显示视频的集合时先前召回过视频的能力。在前几分钟内看到的视频进行识别任务，以进行短期令人难忘，以便在前24到72小时内进行长期难忘。数据包括每个视频的每个识别的反应时间。与每个视频相关联是文本描述（标题）以及应用于从每个视频中提取的3帧的图像级别功能集合（开始，中间和结束）。还提供了视频级功能。数据集在视频难忘任务中使用，作为2020年的Mediaeval基准的一部分。
