Dependency and Constituency Grammar

All languages are made up of words and rules. In other words, langauges are made up of Vocabulary and Structure. Each word defines the meaning of real or abstract entities. The relationship between each words defines the syntax structure, or more precisly Grammar. Traditionally, grammars are generally grouped into Constituency (Phrase Structure) Grammar and Dependency Grammar. Actually, Constituency Grammar or Phrase-Structure Grammar was first proposed by Noam Chomsky to represent languages in Cannonical Form.

However, languages are different; they differ not only in words, but also in grammars. In English, for example, sentences are formed with Subject + Verb + Object. But, in some languages, such as Myanmar (မြန်မာ) and Korean (한글), sentences are formed with Subject + Object + Verb. In such languages, almost all sentences end with Verb.

Myanmar (မြန်မာဘာသာစကား) Language Processing

Since in Myanmar (မြန်မာ) Language, sentences are formed with Subject + Object + Verb. I have come up with RSOV (Reversed Subject Object Verb) Model. In a Myanmar Sentence, the main verb has become the root node, and all others auxiliary verbs and other phrases and words have become leaf nodes, and the relationship between root node and leaf nodes can be easily represented with a Dependency Tree.

English Language Processing

However, in English, sentences are formed with Subject + Verb + Object. In addition, Objects are sometimes defined with Pre-Position, unlike Myanmar, in which, Nouns are followed by particles or Post-Positions. After taking account into different aspects, I have come up with Dependency Tree Structure for Subject + Verb + Object Languages as well.
