You need text written by the person whose personality you're interested in. It should contain words about every day experiences, thoughts, and responses.
You can play with the demo with as little as 100 words, but for a more accurate analysis, you need more words.
The scores you see are all percentiles. They are comparing one person to a broader population. For example, a 90% on Extraversion does not mean that the person is 90% extroverted. It means that for that single trait, the person is more extroverted than 90% of the people in the population.
Our sample population consists of Twitter users who tweet in respective language and whose personalities we calculated using our model.
