índice de Palabras de Contenido (IPC) y Distribución Porcentual de Legomena (DPL) en artículos de investigación en espa？ol

based on a review of classic indices in lexical statistics (laws of estoup-zipf-mandelbrot), two linguistic indices are proposed in order to contribute new data in the description of specialized texts. a case is presented in which these indices are applied to a representative, multidisciplinary corpus of research articles in spanish that is contrasted with seven other corpora serving as a control group. although, from a general point of view the proposed indices present stable behaviour in different registers, implemented specifically, the proposed indices allow the distinction between high and low specialized registers and reveal the disciplinary variation of the corpora analyzed.
