Abstract
It is important for creating a travel-friendly environment to consider old people and young children, who have many issues when traveling. In this study, the attitudes of mothers with infants and toddlers toward travel before and after the COVID-19 pandemic were analyzed using data from mamari, which is a smartphone application for mothers to solve and share questions and concerns about pregnancy, childbirth, and childcare. Latent Dirichlet allocation topic models were constructed for the data, which were user question sentences written in Japanese. Thus, the attitudes of mothers toward travel were investigated using the topic model analysis.
