The technical solution is: to train a neural network model (e.g., CNN model) into a model for question type recognition based on numerous test paper samples in advance, and to use this trained model to detect the position of individual questions, the type corresponding to the question, the different components of the question (stem, answer, picture) in the test paper, and then to identify the printed font character information of the stem and the handwriting font character information of the answer part based on the recognition model, and finally to auto-correct based on the identified character information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for intelligent identification and correction of questions","description":"A method and a system for intelligent identification and correction of a question, which implements, through artificial intelligence, automatic identification of stems of various types of questions an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11508251","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
