Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments.

[0025] In order to solve the problem that the existing electronic map cannot accurately identify the intention of the user's complex question, the embodiment of the present invention provides a query method for traffic travel problems, using the knowledge map technology to realize the knowledge expression of the traffic network, and obtain the traffic knowledge map , and then identify the query intent, and combine it with the traffic knowledge map to achieve the effect of accurately identifying user intent and reducing the number of interactions.

[0026] The knowledge graph is a large-scale semantic network, which is used to describe the relationship...

Abstract

The embodiment of the invention relates to the technical field of traffic, in particular to a traffic travel problem query method and device, which are used for improving the user intention identification accuracy and reducing the man-machine interaction frequency. The method comprises: receiving to-be-queried traffic information; identifying a query intention corresponding to the to-be-queried traffic information; according to the description information type corresponding to the query intention, extracting first description information corresponding to the description information type from the to-be-queried traffic information, and the first description information comprising position description information and relation description information; searching a starting point entity corresponding to the position description information from the traffic knowledge map; wherein the traffic knowledge map comprises all layers of entities in the traffic network and connection relationships among the entities; determining a target entity according to the relationship description information, the starting point entity and a connection relationship between entities included in the traffic knowledge map; and reasoning and inquiring a target result corresponding to the intention according to the traffic knowledge graph, the starting point entity and the target entity. Therefore, the accuracy of identifying the intention of the user can be improved, and the man-machine interaction frequency is reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of transportation, and in particular, to a method and device for inquiring about transportation travel problems. Background technique [0002] At present, the electronic map commonly used in electronic devices, the map search engine organizes data in the form of location points on the map, without describing the relationship between any two location points. Therefore, when using the query function of the existing electronic map, the user needs to input the specified start point, end point and travel mode in order to plan the route. This query function can only be applied to simple question scenarios entered by the user. In addition to the above-mentioned simple problem scenarios, in some other cases, users may encounter complex problem scenarios, such as querying fuzzy geographic location scenarios, querying line transfer scenarios, querying nearby locations, etc. Complex problem...
