CHIIR 2021

6th ACM SIGIR Conference on
Human Information Interaction and Retrieval
Online, 14-19 March 2021

Welcome to the sixth ACM SIGIR Conference on Human Information Interaction and Retrieval (CHIIR) (pronounced “cheer”), which will take place on 14–19 March, 2021 (online). CHIIR provides a forum for the dissemination and discussion of research on the user-centered aspects of information interaction and information retrieval. CHIIR focuses on elements such as human involvement in search activities, and information seeking and use in context. The conference represents a merger of two successful past events: the Information Interaction in Context conference (IIiX) and the Human Computer Information Retrieval symposium (HCIR).
