Abstract: The first edition of the International Workshop on Implicit Author Characterization from Texts for Search and Retrieval (IACT'23) was held on July 27th, 2023, in conjunction with the 46th International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR) in Taipei, Taiwan. To support both online and in-person participation, the workshop was held as a hybrid event. Online participation was allowed using the EventX platform. During the course of the day, about 15 attendees had the opportunity to follow up and discuss the recent advances in topics related to identifying and extracting implicit information about authors (e.g., human or AI) from texts and using it in IR tasks. The workshop program included two invited keynotes, four paper presentations, and the report of the ColiE competition which was held as a part of the workshop1.
