Problems solved by technology

In addition, in the prior art, the user's manual input or voice input is usually required to input the destination, which cannot be predicted automatically, thus completely liberating the user from manual operation
In addition, existing methods can only set one destination, and cannot intelligently learn and adjust the destination according to the user's current path, which is relatively rigid
And the existing method is usually based on the principle of the shortest path when calculating the navigation path. In this way, in the case of multiple destinations, comprehensive consideration and dynamic planning of the path cannot be performed, which affects user experience

Embodiment Construction

[0026] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0027] figure 1 is a block diagram illustrating a path guidance system based on user modeling according to an exemplary embodiment of the present invention.

[0028] Such as figure 1 As shown, the path guidance system based on user modeling according to the present invention includes a client 100 and a server 200 . The client 100 is located at the user side and is used for displaying real-time dynamic route guidance to the user. The client 100 may be any electronic device with a navigation function, for example, it may be a GPS navigator, a smart phone with a GPS function, or other mobile terminal devices. The server 200 can connect and communicate with the client 100 through a wireless network. For example, the server 200 can communicate with the client 100 through an existing mobile communication network (such as GSM, CDMA, WCDMA, CDMA-2000, LTE mo...

Abstract

The invention discloses a route guide system and a route guide method based on user modeling. A route calculation system comprises a client and a server, wherein the client is used for collecting user state information, forming a user log based on the user state information, sending the user log to a server, receiving forecast information from the server and calculating candidate routes according to the forecast information and the current location of a user; the server is used for constructing and updating a user model according to the user log received from the client, forecasting a destination according to the constructed user model and the current user state information when receiving a trigger signal which is used for triggering a route guide function and is sent by the client, and generating the forecast information in a preset format; the user model corresponds to a behavior pattern of the user.

Description

technical field [0001] The present invention relates to the fields of user modeling and intelligent navigation, and more specifically, to a real-time dynamic path guidance system and method based on user modeling. Background technique [0002] User modeling is the process of acquiring and maintaining knowledge related to user interests, needs, or habits, resulting in a user model that represents the user's unique background knowledge, interests, or behavioral patterns. Specifically, the client collects the user's log information, and sends it to the server after the client processes it. The server uses data mining methods to perform user modeling or update the user model according to the set fixed time interval, and The user model is saved to the database. The ultimate goal of the user model is to provide users with personalized services to meet their individual needs. The intelligent navigation system uses the position, speed and time information provided by the satellite...
