As shown in fig. 2, the interactive teaching method includes the following steps 110 to 190:
110. When the fact that the user performs editing operation on the search bar in the operation interface is detected, the current input text of the user is obtained in real time.
The operation interface refers to a main interactive interface of a user, such as an interface screenshot shown in fig. 3, and fig. 3 is a main interface design of user interactive operation, from which key interface elements such as a query frame, an aviation zone display area, a teaching module selection and the like can be seen. A user interface which is modern and has high responsiveness can be designed by using a Bootstrap framework and a Material Design style, and a search bar and a result display area which are intuitive in Design are provided, so that a user can quickly inquire and view results. Specifically, an HTML5 and CSS3 are utilized to construct basic webpage layout, so that cross-platform compatibility is ensured; integrating Bootstrap library, and using predefined components thereof, such as navigation bar, search box, prompt box and the like; through JavaScript or TypeScript, the writing function processes the input of a user, map interaction and data interaction with the back end.
120. A plurality of candidate city names associated with the current input text is obtained.
In the embodiment of the invention, the user inputs the city name, and the system can automatically identify and map to the corresponding aviation zone code. And in the process of inputting by the user, an intelligent suggestion function is provided, and when the user inputs part of characters of the city name, the system can automatically prompt the possible complete city name, so that search suggestion and automatic completion functions can be provided, and the user can be helped to quickly find the target city. Specifically, an autocompletion function can be applied to a search box, necessary JS and CSS libraries are introduced, when a user starts to input, the city names in the back-end database are searched in real time through an Ajax request, and returned data are matched with the current input text of the user, so that a plurality of related candidate city names are obtained.
130. A plurality of candidate city names are displayed below the search bar.
In the embodiment of the invention, a suggestion list is generated according to a plurality of candidate city names and is dynamically displayed below a search box. For example, a dynamically generated drop-down list of city names associated with the user's current input is provided, intelligently ordered according to the user's input speed and historical query records, with the most likely option at the top of the list. Specifically, step 130 may include the following steps 1301 to 1302, not shown:
1301. and calculating the correlation degree of each candidate city name according to the input speed of the user and the historical query record.
1302. And generating a suggestion list according to the names of the candidate cities in the order of the correlation degree from high to low, and displaying the suggestion list in a downward-pull mode under the search bar.
Thus, the user can select one city from the suggestion list, the system automatically fills and executes corresponding inquiry, and the automatic completion function provides a more visual and efficient way for the user to search and select the city, so that the user experience is greatly improved.
In some embodiments, each candidate city name in the keyboard navigation advice list is also supported, and the user may select using up and down arrow keys. Specifically, after step 1302 is performed, the following steps, not shown, may also be performed: when the fact that the user clicks an up arrow key of the keyboard is detected, judging that a pull-up instruction of the user is received; when the fact that the user clicks a down arrow key of the keyboard is detected, judging that a pull-down instruction of the user is received; navigation scrolling is performed among a plurality of candidate city names of the suggestion list according to a pull-up instruction and/or a pull-down instruction.
140. If a confirmation instruction of the user for any candidate city name is received, determining that the candidate city name is the target city name selected by the user.
Illustratively, this step may include the following steps 1401-1402, which are not shown:
1401. when the mouse cursor of the user is detected to be positioned at any candidate city name and the stay time length reaches the appointed time length, the city description information corresponding to the candidate city name is popped up.
1402. If the user is detected to click the enter key of the keyboard within the preset time period, the candidate city name is determined to be the target city name selected by the user after the confirmation instruction of the user is received.
150. And inquiring the aviation division code corresponding to the target city name.
For example, the target city name may be entered into a pre-trained machine learning model such that the machine learning model predicts the corresponding aviation zone code. The machine learning model may employ a bi-directional encoder characterization (Bidirectional Encoder Representations from Transformers, BERT) model from a transformer, which is a deep learning model that is excellent across a variety of text processing tasks. The training process of the machine learning model may include: firstly, a plurality of city name samples are obtained, in order to increase the generalization capability of the model, a data enhancement technology such as random substitution, deletion or insertion can be introduced, and characters in the city name samples are enhanced to obtain enhanced city name samples. And secondly, acquiring aviation division codes corresponding to the city name samples from an aviation division database to form a data set, wherein the data set is divided into a training set and a testing set. Then, a pretrained BERT model is loaded by using a Huggingface library, fine tuning training is carried out on the BERT model by adopting a training set by setting the learning rate, the batch size and the training round number, and then the accuracy of the trained model is evaluated by using an independent testing set, so that iterative optimization is carried out on the model. The city name sample can use city name data of multiple languages, so that the model is ensured to have good cross-language generalization capability.
160. And displaying an aviation division code corresponding to the target city name in a result display area in the operation interface.
As another optional implementation manner, if a confirmation instruction of the user for any candidate city name is not received, when it is detected that the user completes editing operation in a search column in an operation interface, all input texts of the user are obtained, then natural language processing is performed on all input texts to identify and obtain a city name to be queried input by the user, an aviation division code corresponding to the city name to be queried is obtained, and the aviation division code corresponding to the city name to be queried is displayed in a result display area in the operation interface. In addition to displaying the aviation division code, brief information of the city may also be displayed.
The implementation way of performing natural language processing on all the input texts to identify the names of the cities to be queried input by the user can be specifically as follows: firstly, performing text preprocessing on all input texts to obtain a plurality of keywords; and detecting the language type of each keyword, and carrying out semantic analysis on each keyword according to the language type so as to obtain the name of the city to be queried.
The operation interface can support multi-language presentation of the interface and the content by using an i18n framework, and can automatically select an appropriate language version according to the geographic position or language setting of a user.
