Teachers can conduct class tests, and after completion, they can view the class student performance reports and test paper explanations. Students can view their test reports and transcripts through the oral test website.

1. 1. 1. 1. 1. 1. Intelligent Test Subsystem

The intelligent test subsystem includes the invigilator and the test machine. The test invigilator installs the test management program and the invigilator program. The English subject teacher can download the test tasks through the test invigilator. upload. Students use iFLYTEK test earphones to take the test through the test machine, record the candidates' test answers and voice files, and automatically upload them to the invigilator.

The English subject teacher downloads the test tasks from the "Kokao.com" using the test program, starts the test through the invigilator program and invigilates the test process. Candidates log in to the test program to complete the test and automatically upload the test answer sheet to the invigilator for summary. Through the invigilator program After the exam is over, the examinee's answer sheet is uploaded to the "Smart Evaluation Service" through the examination administration program to complete the examinee's grading, and finally generate the examinee's test score report.

1. 1. 1. 1. 1. 1. Smart Evaluation Service

An intelligent evaluation system is needed to better solve the heavy workload caused by manual scoring, reduce human evaluation errors, unfairness caused by fatigue, and provide a multi-dimensional analysis test report. Intelligent evaluation service, integrating advanced intelligent evaluation engine, can conduct intelligent evaluation on candidates' data. The entire evaluation process is carried out automatically without manual participation to ensure the objectivity and authenticity of the scores. The engine can also evaluate the candidates' pronunciation from multiple dimensions, so that teachers can analyze students' oral English level more intuitively, so as to provide more targeted guidance and teaching to students. The intelligent evaluation service can realize offline examinations, automatic scoring and statistics, and timely feedback on the effects of teacher teaching and student learning.

1) Intelligent monitoring service

After the smart scoring service receives the examinee's answer sheet package, it will automatically enter the scoring process, including monitoring of the scoring process, safety verification, result status monitoring, and data format conversion.

2) Data aggregation service

The intelligent evaluation service needs to perform a series of preprocessing procedures on the uploaded task information and the examinee's answer sheet data, and finally generate a task data that can be evaluated by the intelligent engine.

3) Safety verification

The smart assessment service will check the integrity of the uploaded data to confirm that the examinee's data is complete and safe and there are no abnormal files.

4) Smart Scoring Service

The intelligent evaluation service calls Xunfei intelligent evaluation engine for scoring, which can evaluate and obtain the answer data of candidates from multiple dimensions. At the same time, the system will verify the score data to ensure that no score data is lost.

5) Score summary service

The system will summarize the test task scores that have been evaluated into the relevant database for storage, and check again whether there are missing evaluations or other abnormal situations. After confirming that it is normal, the system will automatically synchronize the task score information to the oral test network, and the user can view the score

6) Report Generation Service

Due to the large amount of database query and processing data involved in the full sample analysis and sampling comparison of the score report data, if the data is directly queried from the database table every time and then analyzed and processed, the response speed will be very slow, which will affect the user experience and experience. Based on this, the system will pre-generate all the data required to be reported according to the full sample dimension of the analysis in advance and generate intermediate result data as required. When teachers or students log in to the data management subsystem for report query and analysis, the data files are directly obtained according to different test parameters, and the contents are displayed on the system interface. In terms of speed and efficiency, this processing method is much more efficient than performing analysis and processing by directly querying the data in the database table each time.
