Development of a Japanese Personality Dictionary based on Psychological Methods

摘要

We propose a new approach for constructing a personality dictionary with psychological evidence. In this study, we collect personality words by using word embeddings and construct a personality dictionary with weights for the Big Five traits. The weights are calculated based on the responses of the large sample (N = 1,938, female = 1,004, M = 49.8 years old: 20-78, SD = 16.3). All the respondents answered a 20-item personality questionnaire and 537 personality items derived from word embeddings. We present the procedures to examine the qualities of responses with psychological methods and to calculate the weights. Using these, we develop a personality dictionary with two sub-dictionaries. We also discuss an application of the acquired resources.
