Conference literature refers to the literature materials formed by the activities of experts, scholars and related practitioners gathering at a specific time and place to exchange and discuss the latest research results, experiences and ideas in academic or professional fields. Meeting documents usually include meeting papers, meeting minutes, meeting abstracts, meeting minutes and other forms, which record the theme, agenda, participants, speakers, discussion contents and research results of the meeting. Compared with periodical papers and books, conference documents are timely and cutting-edge, because they can usually reflect the latest research results and development trends more quickly. Therefore, conference documents are also important information sources and reference documents in academic research and professional fields.
