To leverage different skills of transdisciplinary teams, understanding team processes critical for team performance is crucial. This study examined temporal participation equality and creativity using behavioral data and natural language processing. Twenty-one teams of four people generated business ideas for post COVID19 societies in teams. We segmented their discussion based on lexical similarity and clarified the relationship between each segment and generated ideas. Then we calculated the equality of turn-taking and speaking time and examined their relationship with creativity scores of ideas using hierarchical regression analysis. The result suggested temporal participation equality did not relate to creativity. We discussed its implication and future studies.
