This special project aims to develop and compare the performance of gold price prediction models using quantitative variables and news text data. The study incorporates nine key predictors, including Brent crude oil prices, WTI crude oil prices, silver prices, platinum prices, the U.S. Federal Reserve's policy interest rate, the Nikkei 225 index, the Dow Jones Industrial Average, the S&P 500 index, and daily news articles from Bangkok Business News. Relevant news data will be processed using Natural Language Processing (NLP) techniques and integrated with three predictive models: Gradient Boosting, Machine Learning Models, and Regression Analysis. The model performance will be evaluated using three key metrics: Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and the Coefficient of Determination (R*). This research aims to develop a predictive model that effectively utilizes both quantitative variables and news data to enhance gold price forecasting, providing valuable insights for investors and analysts.

Currently, Thailand is facing the issue of an aging agricultural workforce and a shortage of labor. The hiring process for agricultural workers is primarily based on word-of-mouth within a limited, narrow area. This may have indirect negative effects in various aspects, such as the lack of basic selection criteria (experience, skills), budget control, and hiring processes. As a result, the idea of creating a job platform specifically for farmers was conceived.Currently, Thailand is facing the issue of an aging agricultural workforce and a shortage of labor.
