The 2019 reviewing process will be different from the previous years. Papers to be considered for publication in the *ICWSM proceedings* and presentation at the ICWSM 2019 conference must be submitted by one of the two submission deadlines. Authors who receive the "Accept" recommendation will have the opportunity to respond to reviewer suggestions by making minor edits when preparing the camera-ready version. Authors who receive the "Revise and Resubmit" recommendation will have the opportunity to address reviewer suggestions and resubmit an improved manuscript by the next submission deadline. We anticipate that the authors who receive "Revise & Resubmit" in September and get fully accepted in January will be presenting during the 2019 conference. Authors who receive "Revise & Resubmit" in January will likely be presenting during the 2020 conference if their papers get accepted during the next submission round. Papers accepted to this track will be presented as full-length presentations integrated with the conference, and they will be published as journal articles in the *ICWSM proceedings*. A few papers that are not accepted for ICWSM 2018 have been invited to revise and resubmit. For more details about ICWSM history and the relevant disciplines, please refer to the main page. For submission guidelines, please refer to the guidelines page.
The International AAAI Conference on Web and Social Media (ICWSM) is a forum for researchers from multiple disciplines to come together to share knowledge, discuss ideas, exchange information, and learn about cutting-edge research in diverse fields with the common theme of online social media. This theme includes developing new perspectives in social theories as well as new approaches-including quantitative, qualitative and profoundly mixed methods-for analyzing vast and unstructured data. ICWSM is a singularly fitting venue for research that blends social science theories and methods with computational approaches to answer important and challenging questions about human social behavior through social media.
