研究目的
To investigate global interests in organic foods using query data from the Google search engine and deep learning methods.
研究成果
The study found that organic oil, organic milk, organic chicken, and organic apples are the most interested organic foods. People from Singapore, the US, New Zealand, Australia, the United Kingdom, and Canada are most interested in organic foods. There is no significant correlation between people’s interest in organic foods and GDP or life expectancy, but there are significant correlations with education level and cultural dimensions. An RNN model can predict people’s interest in organic foods with small relative errors.
研究不足
The study relies on search engine data, which may not fully capture all aspects of consumer behavior. The prediction errors for grains and meats were relatively larger than for other categories.
