Error Taxonomy

A systematic classification of the types of errors that users or learners commonly make, organised into categories based on the nature, source, or linguistic level of the error. In accessibility and educational technology, error taxonomies are used to build intelligent systems that can recognise, categorise, and respond to specific error patterns. For example, a writing tool for deaf learners of English might classify errors into categories like missing articles, verb agreement mistakes, or prepositional errors, with subcategories reflecting whether errors stem from first-language transfer, developmental patterns, or other sources. A well-designed error taxonomy enables targeted, adaptive feedback rather than generic error messages.
