Identifying and Predicting Temporal Change of Basic Human Values from Social Network Usage

摘要

Basic Human Values represent a set of values such as security, independence, success, kindness, and pleasure what we think are important to our lives. Each of us holds different values with different degrees of importance. Existing studies show that values of a person can be identified from her social network usage. However, the value priority of a person may change over time due to different factors such as time, event, influence, social structure, and technology. In this research, we are the first to investigate whether the change of value priorities can be identified from social network usage. We have proposed a HMM based technique to capture the change of values of a person.
