In terms of research into chat interfaces, prior research includes studies applicable to the reader's side, aimed at reducing the reader's perceived waiting time. However, this paper focuses on the writer's side. Content from live video seminars typically contains greetings and salutations uttered by participants. These salutations were removed first from the data in order to eliminate noise, before starting the analysis. The sentences within each chat utterance were analyzed, and the results indicate that approximately 90% of those utterances are less than 20 characters long, and approximately 54% of them are less than 10 characters in length. In addition, this research analyzed the structure of the sentences, and the results show that utterances comprising of two or more sentences tend to include questions. However, at the same time, this has also highlighted the issue that these types of sentences tend to hinder synchronization within the webinar.
