And the second method comprises the following steps: the food searching request comprises first taste characteristics, and the first taste characteristics are obtained by detecting the food to be searched through a taste sensor by the first terminal. The server responds to the food searching request, converts the first taste characteristics based on the characteristic conversion model to obtain third taste characteristics, and searches second taste characteristics matched with the third taste characteristics from the food characteristic database.

Wherein the first flavor characteristic belongs to a third format and the third flavor characteristic belongs to a fourth format. If the first flavor characteristics sent by the first terminal are detected by the first terminal through the flavor sensor, the server receives a food search request sent by the first terminal, and then converts the first flavor characteristics in the third format based on the characteristic conversion model to obtain third flavor characteristics in a fourth format, wherein the third flavor characteristics in the fourth format meet the requirement of the server for searching the second flavor characteristics, so that the server responds to the food search request and searches from the food characteristic database according to the third flavor characteristics to obtain second flavor characteristics matched with the third flavor characteristics.

In some embodiments, if the server needs to convert the first flavor feature using the feature conversion model, the feature conversion model needs to be trained first, and the process of training the feature conversion model includes: obtaining a first sample flavor characteristic and a second sample flavor characteristic of the sample food, the first sample flavor characteristic belonging to a third format and the second sample flavor characteristic belonging to a fourth format. And the server trains the characteristic conversion model based on the first sample taste characteristics and the second sample taste characteristics to obtain the trained characteristic conversion model.

Before the server converts the flavor features based on the feature conversion model, the server needs to train the feature conversion model first, so that the trained feature conversion model can convert the third format of the flavor features into the fourth format. The server firstly obtains a first sample flavor characteristic belonging to a third format and a second sample flavor characteristic belonging to a fourth format, inputs the first flavor and flavor characteristic of the third format into a characteristic conversion model to obtain a training flavor characteristic, and adjusts parameters of the characteristic conversion model according to the difference between the training flavor characteristic of the fourth format and the second sample flavor characteristic to obtain the adjusted characteristic conversion model.

Optionally, the second sample flavor characteristics of the second format of the sample item are evaluated by the reviewer based on the flavor of the food item to obtain second sample flavor characteristics that belong to the second format.

In the embodiment of the application, the food is detected by the flavor sensor to obtain the flavor characteristics, so that the flavor which is difficult to accurately describe through characters is digitalized, the expression mode of the flavor is expanded, the description accuracy of the flavor is improved, and the food searching accuracy according to the flavor is further improved.

Next, how to determine the second food item characteristic matching the first food item characteristic will be described.

In some embodiments, a degree of match between the first food characteristic and the second food characteristic is obtained, and at least one second food characteristic with the greatest degree of match is selected from the food characteristic database.

In the embodiment of the application, the server acquires the matching degree between the first food characteristic and the second food characteristic, the matching degree is adopted to represent the matching degree between the first food characteristic and the second food characteristic, and then at least one second food characteristic with the largest matching degree is selected according to the acquired matching degree between the first food characteristic and the second food characteristic.

The greater the matching degree between the first food characteristic and the second food characteristic, and therefore, the food characteristic with the greater matching degree is selected as the second food characteristic matching with the first food characteristic.

For example, the second food characteristics are sorted according to the sequence of the matching degrees from high to low, and then the second food characteristics in the preset number at the front are selected according to the sorting sequence to be determined as the second food characteristics matched with the first food characteristics.

The preset number is set by the server, or the preset number is set by an operator, or other modes are adopted.

For another example, a second food characteristic with a matching degree greater than a preset matching degree is obtained, and the second food characteristic is determined to be matched with the first food characteristic.

The preset matching degree is set by the server, or the preset matching degree is set by an operator, or other modes are adopted.

For example, the preset matching degree is 0.6, and if the second matching degree obtained by the server is greater than 0.6, the second matching degree is determined as the second matching degree matching with the first food characteristic.

In the embodiment of the present application, when the server obtains the matching degree between the first food characteristic and the second food characteristic, the matching degree between the first food characteristic and the second food characteristic needs to be determined according to the first flavor characteristic and the first flavor characteristic, respectively.

When the pressure sensor 1513 is disposed at a lower layer of the display screen 1505, the processor 1501 controls the operability control on the UI interface in accordance with the pressure operation of the user on the display screen 1505. The operability control comprises at least one of a button control, a scroll bar control, an icon control and a menu control.

The fingerprint sensor 1514 is configured to capture a fingerprint of the user, and the processor 1501 identifies the user based on the fingerprint captured by the fingerprint sensor 1514, or the fingerprint sensor 1514 identifies the user based on the captured fingerprint. Upon recognizing that the user's identity is a trusted identity, the user is authorized by processor 1501 to have relevant sensitive operations including unlocking the screen, viewing encrypted information, downloading software, paying for and changing settings, etc. The fingerprint sensor 1514 may be disposed on the front, back, or side of the terminal 1500. When a physical key or vendor Logo is provided on the terminal 1500, the fingerprint sensor 1514 may be integrated with the physical key or vendor Logo.

The optical sensor 1515 is used to collect ambient light intensity. In one embodiment, processor 1501 may control the brightness of display screen 1505 based on the intensity of ambient light collected by optical sensor 1515. Specifically, when the ambient light intensity is high, the display brightness of the display screen 1505 is increased; when the ambient light intensity is low, the display brightness of the display screen 1505 is adjusted down. In another embodiment, the processor 1501 may also dynamically adjust the shooting parameters of the camera assembly 1506 based on the ambient light intensity collected by the optical sensor 1515.

A proximity sensor 1516, also known as a distance sensor, is typically provided on the front panel of the terminal 1500. The proximity sensor 1516 is used to collect the distance between the user and the front surface of the terminal 1500. In one embodiment, when the proximity sensor 1516 detects that the distance between the user and the front surface of the terminal 1500 gradually decreases, the processor 1501 controls the display 1505 to switch from the bright screen state to the dark screen state; when the proximity sensor 1516 detects that the distance between the user and the front surface of the terminal 1500 gradually becomes larger, the processor 1501 controls the display 1505 to switch from the breath screen state to the bright screen state.
