I am detecting psychology traits from a very large set of text and so far, I am able to extract the big 5 personality traits(extraversion, agreeableness, openness, conscientiousness, and neuroticism). Therefore, I am trying to extract extra traits from the text, such as self-esteem (texts about romantic partners) trait and narcissists(texts about personal achievement).
So I am trying now to come up with new traits from the texts such as sense of purpose (https://www.psychologytoday.com/blog/out-the-darkness/201307/the-power-purpose), is there any way to extract this feature? Also, is there any personality traits you can propose to include
PS: any recommendation for extracting new personality traits will be highly appreciated :)
