formsHindi

formsHindi is a linguistic resource and software toolkit designed to manage and generate inflected forms in the Hindi language. It provides a comprehensive lexicon of base forms (lemmas) and a rule-based morphological engine that models noun declensions, pronoun inflections, adjective agreement, numeral forms, and full conjugation of verbs across tense, aspect, mood, voice, person, number, and gender. The project supports both Devanagari and Latin transliteration, and stores data in a modular format suitable for integration into natural language processing pipelines.

The core components of formsHindi include a morphological analyzer that identifies possible morphemes and grammatical features for a given surface form, a morphological generator that produces valid surface forms from lemmas and feature specifications, and a lexicon with metadata such as part of speech and semantic notes. It also provides a scripting interface for applying rules, and options for exporting results in common formats used by NLP tools.

Data in formsHindi is sourced from standard Hindi dictionaries, linguistic descriptions, and corpus-based observations, with emphasis on broad coverage of everyday vocabulary and common inflection patterns. The resource is intended for researchers and developers and is typically distributed under open licenses on public repositories, enabling modification and redistribution.

Applications for formsHindi span a range of natural language processing and language technology tasks, including tokenization, lemmatization, part-of-speech tagging, grammatical error detection, machine translation, and language learning applications. Limitations include the complexity of Hindi morphology, such as postpositional phrases and sandhi, which may require supplementary rules or domain-specific adaptation to achieve full coverage for specialized vocabularies.
