Code of Conduct

The annual conference of the Educational Data Mining society is intended to foster community and exchange of ideas among those working in the field of educational data mining.

Everyone involved in the conference -- from organizers to presenters to attendees to sponsors -- is expected to adhere to the code of conduct throughout the conference, both in their formal and informal participation in the conference and in all channels of interaction and communication, including social media. The EDM 2021 code of conduct described here is inspired by and adapted from similar codes of conduct from recent international conferences on machine learning and artificial intelligence (ICLR, ICML).

Everyone has a right to participate in the conference free from harassment and intimidation, and in an environment that recognizes the inherent worth of all people and their potential to contribute valuable ideas to the scientific discussion. Everyone has the right to a safe and discimination-free conference regardless of race, ethnicity, national origin, gender identity, gender expression, socioeconomic status, sexual orientation, disability status, religion or lack of religion, physical appearance, technology choices, or other identities or beliefs. What may be intended as “joking” can be offensive and demeaning. Bullying, intimidation, personal attacks, harassment, sustained disruption of talks or other events, and behavior that interferes with another participant's full participation will not be tolerated. This includes but is not limited to sexual harassment, unwelcome repeated contacts, harassing photography or recording, unwelcome sexual attention, display of belittling or gratuitous images in public spaces, public vulgar exchanges, and diminutive characterizations, which are all unwelcome in this community. Revealing private information in a public setting without permission, such as posting a participant’s personal information, is not permitted.

If you see someone engaging in any of these behaviors, please ask them to stop. If you experience or observe any behavior you’re concerned about or that you believe may constitute harassment or discrimination, please report it to program co-chairs Sharon Hsiao (sharon.Hsiao@asu.edu) and Shaghayegh (Sherry) Sahebi (ssahebi@albany.edu) via email with subject line “EDM’21 - concerning observation”. During the conference, we will follow up within 24 hours, and outside the days of the conference, we will respond within two business days.

Consequences for violating this code of conduct will be decided by the program and general chairs and may include a formal or informal warning, expulsion from the virtual conference with no refund, barring from participation in future conferences or the EDM organization, reporting the incident to the offender’s local institution or funding agencies, or other actions. A response of "just joking" will not be accepted; behavior can be harassing without an intent to offend. If action is taken, an appeals process will be made available.
