A Semantic Awareness-Based Top-k Multi-Request Path Planning Method |
| abstract |
The invention discloses a Top-k multi-request path planning method based on semantic perception, which searches the top k shortest paths covering all keywords according to the query keywords of users. This method takes into account the relationship between POI (Point of Interest) and user requests, especially when a single POI can satisfy multiple requests from users; establish a priority relationship for search keywords, and query high-level keywords first. The keywords that do not have a priority relationship are randomly queried, which realizes the overall disordered and partially ordered keyword query and enables the nearest neighbor query. In this process, the semantic difference compensation distance, the actual distance and the possible extension distance in the future are comprehensively considered. A new formula is used to determine the nearest neighbor distance. |
