基于艾宾浩斯遗忘曲线的英语四级词汇记忆系统v1.0.1

User triggers learning by saying '开始背单词'. System checks user schedule, presents new words with phonetic, part of speech, and Chinese definitions, then conducts quizzes to ensure retention. This supports CET-4 exam preparation for Chinese college students.

System sends push notification at scheduled times (e.g., 8:00 AM) saying it's time to review words due based on the Ebbinghaus forgetting curve. User can reply to start review, improving long-term memory. Ideal for exam preparation.

When a new user says '开始背单词', the system guides them to set daily study time and number of new words per session, storing preferences in user_schedule.csv. This personalizes the learning experience and schedules reminders accordingly.

After learning, the system tests via spelling, multiple choice, and translation quizzes. Incorrect answers trigger re-learning until mastered, providing a comprehensive assessment of vocabulary proficiency.

Offer basic vocabulary learning for free, while charging for advanced analytics such as detailed forgetting curve graphs, personalized review schedule optimization, and progress reports. Revenue from subscription fees.

Sell additional vocabulary packs targeted at specific exams (e.g., CET-6, IELTS) or themed sets (e.g., business, medical). Users buy packs for lifetime access. Revenue from one-time purchases.

License the system to universities and training institutions for their students' CET-4 preparation. Provide bulk user management, teacher dashboards, and integration with school timetables. Revenue from annual licensing fees.
