The Mouse Action Recognition System (MARS): multi-worker behavior annotation data

This dataset was collected to quantify inter-annotator variability in manual labeling of social behaviors in freely interacting mice. We provided a group of graduate students, postdocs, and technicians in the Anderson lab with written descriptions of close investigation, mounting, and attack behaviors (included below), and instructed them to score a set of ten resident-intruder videos, all taken from unoperated mice. Annotators were given front- and top-view video of social interactions, and scored behavior using either Bento or the Caltech Behavior Annotator, both of which support simultaneous display of front- and top-view video and frame-by-frame browsing and scoring. All but one annotator (Human 4) had previous experience scoring mouse behavior videos; Human 4 had previous experience scoring similar social behaviors in flies.
