A Rule based Yoruba Natural Language Interpreter # Rosetta: ## A Rule Based Yorùbá Natural Language Interpreter Rosetta is a rule-based natural language interpreter for the **Yorùbá** language implemented in Java. It compiles a sentence parser, morphological analyzer, grapheme-to-phoneme (G2P) phonetic generator, and spelling correction assistant into an interactive, line-editing shell. ## Architectural Overview The interpreter parses and processes natural language inputs using the following pipeline: ## Supported Sentence Structures * **Basic Sentences (`SV` / `SVO`)**: * **SV (Subject + Verb)**: `Oko mi tobi` (Subject NP + Verb) * **SVO (Subject + Verb + Object)**: `Mo ra aṣọ` (Subject NP + Verb + Object NP) * **Compound Sentences**: Sentences connected by conjunctions. * *Structure*: `[NP VP] + CONJUNCTION + [NP VP]` * *Example*: `Mo ra aṣọ ati oko mi tobi` * **Noun Phrase (NP)**: * Pronouns (e.g., `Mo`, `mi`). * Nouns (e.g., `aṣọ`). * Complex noun phrases containing optional determiners, compound nouns, possessive markers, and trailing adjectives (e.g., `ọkọ mi pupa yẹn`). * **Verb Phrase (VP)**: * Verbs (e.g., `ra`, `tobi`). * Verbs preceded by auxiliary markers (`yóò`) or negation markers (`kò`). * Verbs followed by optional objects, adverbs, or prepositional phrases. * **Prepositional Phrase (PP)**: * Preposition followed by a noun phrase (e.g., `ní ọjà`). ## Limitations The following are outside the parser's scope. * **Serial Verb Constructions (SVC)**: Sentences containing consecutive verbs without conjunctions (e.g., *Ó gbé àpótí wọlé*) are not supported. * **Focus & Topicalization**: Fronting nouns or verbs for emphasis using the focus particle *ni* (e.g., *Aṣọ ni mo rà*) will fail SVO validation. * **Relative Clauses**: Subordinate clauses modifying nouns via the relative marker *tí* (e.g., *ọkọ tí mo rà*) are not supported. * **Interrogatives (WH-Questions)**: Question formats using fronted interrogative pronouns (e.g., *Kí ni o rà?*) are not handled. * *Minor Limitation:* The table in the ter …
