Query: The Effect of Pets on Happiness: A Large-scale Multi-Factor Analysis
  using Social Multimedia   From reducing stress and loneliness, to boosting productivity and overall
well-being, pets are believed to play a significant role in people's daily
lives. Many traditional studies have identified that frequent interactions with
pets could make individuals become healthier and more optimistic, and
ultimately enjoy a happier life. However, most of those studies are not only
restricted in scale, but also may carry biases by using subjective
self-reports, interviews, and questionnaires as the major approaches. In this
paper, we leverage large-scale data collected from social media and the
state-of-the-art deep learning technologies to study this phenomenon in depth
and breadth. Our study includes four major steps: 1) collecting timeline posts
from around 20,000 Instagram users, 2) using face detection and recognition on
2-million photos to infer users' demographics, relationship status, and whether
having children, 3) analyzing a user's degree of happiness based on images and
captions via smiling classification and textual sentiment analysis, 3) applying
transfer learning techniques to retrain the final layer of the Inception v3
model for pet classification, and 4) analyzing the effects of pets on happiness
in terms of multiple factors of user demographics. Our main results have
demonstrated the efficacy of our proposed method with many new insights. We
believe this method is also applicable to other domains as a scalable,
efficient, and effective methodology for modeling and analyzing social
behaviors and psychological well-being. In addition, to facilitate the research
involving human faces, we also release our dataset of 700K analyzed faces.
