Project Main Findings

In this data blog, I explore the text in the HappyDB, which contains more than 100,000 happy moments from over 10,000 contributors. In this project, a LDA model using Gibbs sampling with 10 topics is fitted. Then, I plot several bar plots to get more insights into each fitted topics. Finally, I use the LDA model to answer the following questions:

  • Which countries have more common happy moments?

    • Most main western countries, like USA, AUS, BGR, FRA, CAN, are in the same cluster.
    • For cluster 1, there is only one country, CRI or The Costa Rica. Perhaps this is due to the culture difference and geographic reason.
  • What are the differences in happiness between people of different marital status?

    • The most popular topics among single people are school, pet and travel.
    • Married people are most interested in Shopping and friends.
    • For divorced people, Family is the most popular topics.
