In order to facilitate the calculation of road network distance,the organization and rapid acquisition of object text information and time information,improve G-Tree to add timestamp and inverted sequence related information to the index structure,and call G-Tree containing timestamp and inverted sequence related information as IGT-Tree,two recommendation algorithms are designed,one is a time-based target point query algorithm,and the other is a path recommendation algorithm based on the target point query algorithm.Finally,the efficiency of the proposed algorithm is verified by comparing the G-Tree algorithm in the time-based keyword road network.
