Theory, Opinion and Reflection (TOR) are position papers that critically look at ongoing and emerging research topics, reflections on persistent or fleeting trends in the field and blue sky future ideas for UMAP research. They offer an opportunity for discussing thought-provoking work relevant to the UMAP community, albeit they are not yet ready to be published as a full length research papers at a refereed conference. They should be of sufficient quality and relevance to the UMAP community and demonstrate the ability to spur discussion and debate on the future course of the UMAP research. The presentations will be in the form of a 10 minute pitch in a plenary conference session, just before a break. The presenters will present the topic and raise relevant questions to stimulate discussion during the breaks. Submissions should have a maximum length of 4 pages in the ACM SIG proceedings template. SUBMISSION AND REVIEW PROCESS Submissions must adhere to the ACM SIG Standard (SIGCONF) proceedings template.

They will be assessed based on their originality and novelty, potential to stimulate discussion on important research questions, potential contribution to UMAP research and practice, potential impact in particular use cases, as well as their overall readability. Papers that exceed the page limits (4 pages for TOR) or do not adhere to the formatting guidelines will be returned without review. IMPORTANT DATES · Submission of TOR papers: March 16th, 2019 · Notification of acceptance: April 5th, 2019 · Camera-ready versions of accepted papers: April 15th, 2019 Note: The submissions times are 11:59 pm Anywhere on Earth.
