Information Architecture (IA) Summit is a global gathering for practitioners in the field of information architecture, which has been held for 19 consecutive years until 2018. This paper, firstly, extracts the texts of the conference materials in the IA Summit official website. Then, through the subject analysis method combining qualitative analysis and quantitative analysis, this paper analyzes the main features of the IA Summit from 2000 to 2018, the development process of information architecture reflected by IA Summit. Next, referring to the famous information architecture theory, Three-Ring Structure, this paper analyzes the research progress of the basis of the information architecture design pattern in recent years, namely the three major areas: content, users, and backgrounds. Finally, this paper summarizes the development trend of information architecture.
