Welcome to the 27th ACM International Conference on User Modeling, Adaptation and Personalization - ACM UMAP 2019. This is the premier international conference for researchers and practitioners working on systems that adapt to individual users, to groups of users, and that collect, represent, and model user information. ACM UMAP is the successor to the biennial User Modeling (UM) and Adaptive Hypermedia and Adaptive Web-based Systems (AH) conferences that were merged in 2009. It is sponsored by ACM SIGCHI and SIGWEB, and organized with User Modeling Inc. as the Steering Committee The conference has a long tradition, so a number of submission types, presentation formats and procedures are established and have been shown to be successful. In this year's conference we built on these traditions and also explored new strands. The main components of this conference include eight main tracks, seven workshops, two tutorials, three keynotes, the doctoral consortium, the track on late-breaking results & demos, as well as the theory, opinion and reflection track. This year's motto was "Making Personalization Transparent: Giving control back to the User". |
