- Stochastic_context-free_grammar abstract "Grammar theory to model symbol strings originated from work in computational linguistics aiming at understanding the structure of natural languages. Through controlled grammar exploring and scoring the correctness of a sentence construct in a language by computation is achievable. Grammars are said to be generative grammars/transformational grammars if their rules are used to predict/emit words forming grammatical sentences. Probabilistic context free grammars (PCFG) have been applied in probabilistic modeling of RNA structures almost 40 years post their introduction in computational linguistics.PCFGs extend context-free grammars similar to how hidden Markov models extend regular grammars. Each production is assigned a probability. The probability of a derivation (parse) is the product of the probabilities of the productions used in that derivation. These probabilities are typically computed by machine learning programs operating on large databases. A probabilistic grammar's validity is constrained by context of its training dataset.PCFGs have application in areas as diverse as natural language processing to the study the structure of RNA molecules and design of programming languages. Designing efficient PCFG grammars has to weigh factors of scalability and generality. Issues such as grammar ambiguity need to be resolved. The grammar design influences results accuracy. Grammar parsing algorithms have various time and memory requirements.".
