Predicting Video Memorability Task
2019 MediaEval Benchmarking Initiative for Multimedia Evaluation

The Predicting Video Memorability Task focuses on the problem of
predicting how memorable a video will be. It requires participants to
automatically predict memorability scores for videos, which reflect
the probability of a video being remembered.

Participants will be provided with an extensive dataset of videos with
memorability annotations, and pre-extracted state-of-the-art visual
features. The ground truth has been collected through recognition
tests, and, for this reason, reflects objective measures of memory
performance. In contrast to previous work on image memorability
prediction, where memorability was measured a few minutes after
memorization, the dataset comes with ‘short-term’ and ‘long-term’
memorability annotations. Because memories continue to evolve in
long-term memory, in particular during the first day following
memorization, we expect long-term memorability annotations to be more
representative of long-term memory performance, which is used
preferably in numerous applications.

Participants will be required to train computational models capable of
inferring video memorability from visual content. Optionally,
descriptive titles attached to the videos may be used. Models will be
evaluated through standard evaluation metrics used in ranking tasks.

Target communities
Researchers will find this task interesting if they work in the areas
of human perception and the impact of multimedia on perception such as
image and video interestingness, memorability, attractiveness,
aesthetics prediction, event detection, multimedia affect and
perceptual analysis, multimedia content analysis, machine learning
(though not limited to).

Data is composed of 10,000 short (soundless) videos extracted from raw
footage used by professionals when creating content. Each video
consists of a coherent unit in terms of meaning and is associated with
two scores of memorability that refer to its probability to be
remembered after two different durations of memory retention.
Memorability has been measured using recognition tests, i.e., through
an objective measure, a few minutes after the memorization of the
videos, and then 24 to 72 hours later. The videos are shared under
Creative Commons licenses that allow their redistribution. They come
with a set of pre-extracted features, such as: Dense SIFT, HoG
descriptors, LBP, GIST, Color Histogram, MFCC, Fc7 layer from AlexNet,
C3D features, etc.

Participants to the task are invited to present their results during
the annual MediaEval Workshop, which will be held by the end of
October 2019, in Nice, France, co-located with ACM Multimedia 2019.
Working notes proceedings are to appear with CEUR Workshop Proceedings
