The present disclosure solves the problem that the short text content is sparse to some extent, thereby improving the performance of short text classification."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Text classification system based on feature selection and method thereof","description":"The present disclosure discloses a text classification system based on feature selection and a method thereof in the technical field of natural language processing and short text classification, compr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11960521","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.
