Abstract

A method for detecting drunk requesters in an O2O service platform is provided. The method may include obtaining information related to a request of an O2O service initiated by a requester. The method may also include determining a probability that the requester has consumed alcohol using an alcohol consumption prediction model based on the information related to the request, and determining whether the probability is greater than a threshold. In response to a determination that the probability is greater than the threshold, the method may further include obtaining information related to the requester, and determining whether the requester has consumed alcohol based on the information related to the requester. In response to a determination that the requester has consumed alcohol, the method may further include transmitting a notification that the requester has consumed alcohol to a provider terminal corresponding to the request of the O2O service.

First claim

1 . A system for detecting drunk requesters in an Online to Offline (O2O) service platform, comprising:
a data exchange port communicatively connected to a network; at least one non-transitory computer-readable storage medium including a set of instructions; and at least one processor in communication with the data exchange port and the at least one non-transitory computer-readable storage medium, wherein when executing the set of instructions, the at least one processor is configured to direct the system to:
obtain information related to a request of an O2O service initiated by a requester via the data exchange port;
determine a probability that the requester has consumed alcohol using an alcohol consumption prediction model based on the information related to the request;
determine whether the probability that the requester has consumed alcohol is greater than a threshold;
in response to a determination that the probability that the requester has consumed alcohol is greater than the threshold, obtain information related to the requester;
determine whether the requester has consumed alcohol based on the information related to the requester; and
in response to a determination that the requester has consumed alcohol, transmit a notification that the requester has consumed alcohol to a provider terminal corresponding to the request of the O2O service via the data exchange port.

2 . The system of claim 1 , wherein the information related to the request includes at least one of a request time, a start location of the request, a location of the requester, an estimated distance between the start location of the request and the location of the requester, profile information of the requester, or historical feedback information with respect to the requester.

3 . The system of claim 1 , wherein the alcohol consumption prediction model is generated according to a model training process, the model training process including:
obtaining a plurality of historical orders; obtaining a first set of historical orders with positive feedbacks from the plurality of historical orders; obtaining a second set of historical orders with negative feedbacks from the plurality of historical orders; obtaining a preliminary model; and generating the alcohol consumption prediction model by training the preliminary model using the first set of historical orders with positive feedbacks and the second set of historical orders with negative feedbacks.

4 . (canceled)

5 . The system of claim 1 , wherein to obtain information related to the requester, the at least one processor is further configured to direct the system to:
transmit a request to turn on a camera of a requester terminal associated with the requester via the data exchange port; upon receiving an approval of the request from the requester, transmit a command via the data exchange port to the requester terminal to record at least one image or video; and receive the at least one image or video from the requester terminal via the data exchange port.

6 . The system of claim 1 , wherein to obtain the information related to the requester, the at least one processor is further configured to direct the system to:
transmit a request to obtain an audio of the requester to at least one of a requester terminal or a provide terminal via the data exchange port, causing the at least one of the requester terminal or the provider terminal to activate the audio recording in the at least one of the requester terminal or the provider terminal; and receive a recorded audio from the at least one of the requester terminal or the provider terminal via the data exchange port.

7 . (canceled)

8 . The system of claim 1 , wherein to determine whether the requester has consumed alcohol based on the information related to the requester, the at least one processor is further configured to direct the system to perform at least one of:
analyzing acoustic properties of speech of the requester based on an audio or a video of the requester; analyzing facial features of the requester based on an image or the video of the requester; analyzing body movements of the requester based on behavior information related to the requester; or analyzing physiological parameters of the requester based on physiological information of the requester.

9 . The system of claim 8 , wherein to analyze acoustic properties of speech of the requester, the at least one processor is further configured to direct the system to perform at least one of:
determining a voice rate based on the audio or the video of the requester; determining a voice tone based on the audio or the video of the requester; determining a number of pauses in the audio or the video of the requester; obtaining one or more keywords from the audio or the video of the requester; determining durations of sentences spoken by the requester in the audio or the video of the requester; determining a frequency of misarticulations in the audio or the video of the requester; determining a Linear Prediction Coefficient (LPC) based on the audio or the video of the requester; or determining a Mel-scale Frequency Cepstral Coefficient (MFCC) based on the audio or the video of the requester.

10 . The system of claim 8 , wherein to analyze facial features of the requester based on an image or a video of the requester, the at least one processor is further configured to direct the system to perform at least one of:
determining colors of at least one of the face or the neck of the requester; determining pupil sizes of the requester; determining a blinking frequency of the requester; determining a nodding frequency of the requester; determining a yawning frequency of the requester; or determining an eye closure duration of the requester.

11 . The system of claim 8 , wherein to analyze body movements of the requester based on behavior information related to the requester, the at least one processor is further configured to direct the system to perform at least one of:
determining whether the torso of the requester wobbles unsteadily; or determining whether at least one leg of the requester wobbles unsteadily; or determining whether at least one arm of the requester wobbles unsteadily.

12 . The system of claim 8 , wherein to analyze physiological parameters of the requester based on the physiological information of the requester, the at least one processor is further configured to direct the system to perform at least one of:
obtaining a blood sugar level of the requester based on the physiological information of the requester; obtaining a blood pressure of the requester based on the physiological information of the requester; obtaining a breathing rate of the requester based on the physiological information of the requester; obtaining a body temperature of the requester based on the physiological information of the requester; or obtaining a heart rate of the requester based on the physiological information of the requester.

13 . A method implemented on a computing device having at least one processor, at least one computer-readable storage medium, and a communication platform connected to a network, comprising:
obtaining information related to a request of an Online to Offline (O2O) service initiated by a requester via a data exchange port; determining a probability that the requester has consumed alcohol using an alcohol consumption prediction model based on the information related to the request; determining whether the probability that the requester has consumed alcohol is greater than a threshold; in response to a determination that the probability that the reques
