Conversation in elderly people

[data.txt]<br>We recorded conversations of groups of four or five with 65 older Japanese people between June and September 2018. There were 16 groups and they were fixed over 14 sessions. In addition, as a condition, eight groups were required to speak freely and the remaining eight groups were required to make a presentation. Each session took place once a week for approximately 30 minutes. We decomposed the raw conversation into words and lemmatized the words. All words have been replaced with numbers to exclude personal information. The word column in the data represents words; the id column represents participants from 1 to 65; session represents session numbers from 1 to 14; group represents 16 groups from A to P; condition represents either free conversation or presentation; and the word column represents the number of participants. The words are arranged in the order of time.<br>[data_heaps.txt]<br>This file contains the number of unique words when the number of words increases.
