An overview of AutoFTP. In the framework, we first construct a topic semantic space based on the texts of spatial entities. Then, we initialize a embedding feature space based on the geographical structures of spatial entities. Later, we employ a PSO-based framework to conduct feature-topic pairing through jointly optimizing representation learning, point-wise alignment, pair-wise alignment, and downstream task over learning iterations.
