... extraction and their corresponding attribute classifiers), a temporal extraction system (CRF name entity extraction, their corresponding attribute classifiers, and context-free grammar based normalization system), and a temporal relation system (10 multi-support vector machine (SVM) classifiers and a Markov...

.... Its modeling repertoire includes phylogenetic stochastic context–free grammars and phylo-hidden Markov models. Following earlier tests of XRATE as a machine-learning tool suitable for alignment annotation, we now report the first tests of XRATE as a precise quantitative instrument for estimating...

.... This chapter examines some key findings and ideas concerning the genetics, neurobiology, and evolution of the “language problem.” It also proposes a model for a minimalist neural network parsing context-free grammar and considers arguments in favor of a human-specific adaptive suite. hierarchical structure...

... widespread one is the form of their productions. This article presents a systematic study of the common properties of language families has led to the theory of abstract families of languages. It shows that a context-free grammar generates not only a set of strings, but a set of trees too: each one...

It also discusses the inference algorithms used for each of the models and various other issues of practical concern for the simulations that we report later. context free grammar nonterminal production rule start symbol...

... are in S(1, r). It also explores the use of simple counting methods to compute several growth series before concluding with an overview of cone types, formal languages and context-free grammars, and the DSV method used to compute the growth of grammar productions. The discussion...

...This article focuses on the use of probabilistic context-free grammars (PCFGs) in natural language processing involving a large-scale natural language parsing task. It describes detailed, highly-structured Bayesian modelling in which model dimension and complexity responds naturally to observed...
