Cuescapitalization

Cuescapitalization is a term used in information processing to describe methods for restoring or determining capitalization in text by leveraging contextual cues. It encompasses tasks such as capitalizing at sentence starts, proper nouns, and titles, and may be applied in OCR post-processing, automatic transcription, and text normalization.

Approaches to cuescapitalization include rule-based systems that encode linguistic cues and statistical or machine learning models that learn from annotated corpora. Features commonly used are surrounding words, part-of-speech tags, punctuation, sentence boundaries, capitalization patterns in neighboring tokens, and outputs from named-entity recognition systems. Some implementations combine these cues with language models to produce plausible capitalization for lowercase input or after speech-to-text processing.

Applications of cuescapitalization include improving readability for assistive technologies, enhancing search indexing, and supporting downstream NLP tasks that assume proper case. It is often integrated with broader text normalization pipelines to restore sentence structure and named entities in low-case or mis-capitalized text.

Challenges faced by cuescapitalization involve language variation, ambiguous tokens (such as acronyms and domain-specific terms), multilingual text with diverse capitalization rules, and domain conventions that depart from general language norms. Evaluation typically uses metrics like word-level accuracy or F1 on named-entity restoration, requiring high-quality benchmarks and cross-domain testing to gauge robustness.

Related concepts include capitalization restoration, title casing, and case restoration. Cuescapitalization emphasizes leveraging contextual and linguistic cues rather than fixed rule sets, reflecting a data-informed approach to surface-form normalization in text processing. Example: transforming "the meeting will be in new york" to "The meeting will be in New York."
