Recent Progresses in the Linguistic Modeling of Biological Sequences Based on Formal Language Theory

Treating genomes just as languages raises the possibility of producing concise generalizations about information in biological sequences. Grammars used in this way would constitute a model of underlying biological processes or structures, and that grammars may, in fact, serve as an appropriate tool for theory formation. The increasing number of biological sequences that have been yielded further highlights a growing need for developing grammatical systems in bioinformatics. The intent of this review is therefore to list some bibliographic references regarding the recent progresses in the field of grammatical modeling of biological sequences. This review will also contain some sections to briefly introduce basic knowledge about formal language theory, such as the Chomsky hierarchy, for non-experts in computational linguistics, and to provide some helpful pointers to start a deeper investigation into this field.

Chomsky e Skinner e a polêmica sobre a geratividade da linguagem / Chomsky and Skinner and the controversy over the generativity of language

O Verbal Behavior é considerado a obra mais importante de B. F. Skinner. Pela sua importância este livro foi amplamente discutido e criticado. Uma das críticas mais importantes foi a Resenha (Review) de N. Chomsky, a qual tinha como um de seus argumentos basilares a idéia de que o Verbal Behavior não trataria do caráter gerativo da linguagem humana. Neste contexto, o objetivo deste trabalho foi apresentar a Resenha, sistematizando seus argumentos e sinalizando como Chomsky considerou que a visão behaviorista seria incapaz de explicar a geratividade da linguagem para, em seguida, apresentar como o Verbal Behavior de Skinner possui argumentos que podem contemplar esse caráter gerativo. Como pano de fundo da discussão, uma breve análise histórica das duas obras foi realizada para que o contexto das publicações pudesse ser compreendido.

Verbal Behavior is considered to be B. F. Skinner's most important work. On account of its importance, this book has been widely discussed and critiqued. One criticism came in the Review by N. Chomsky, which had, as one of its fundamental arguments, the idea that Verbal Behavior would not address the generative nature of human language. Set against this context, the objective here was to present the Review, by systematizing the arguments and signaling how Chomsky considered the behaviorist view would be unable to account for the generativity of language, and then to demonstrate how Skinner's Verbal Behavior has arguments that can address this generative character. As a backdrop to the discussion, a brief historical analysis of the two works was performed in order to better understand the context of the publications.
