Resumen

En este artículo se aplican algunos métodos de clasificación a un conjunto de textos con el objetivo de estudiar la probabilidad que el libro Novela de la tía fingida haya sido escrita por Miguel de Cervantes. Esta novela se le ha atribuido históricamente, pero existen algunas posiciones encontradas al respecto. Los métodos usados en este artículo contemplan: regresión logística, regresión logística aditiva, análisis discriminante lineal, cuadrático, regularizado, de mezclas y flexible, árboles de clasificación, método de los k-ésimos vecinos más cercanos, método de Bayes ingenuo y máquinas de soporte vectorial.
Los métodos fueron calibrados y aplicados utilizando un corpus de autores contemporáneos a Cervantes (Lope de Vega, Jerónimo de Pasamonte, Alonso Fernández de Avellaneda, Mateo Alemán y Francisco de Quevedo) junto con más de cuarenta variables, principalmente palabras y signos de puntuación, medidas sobre muestras de los textos escritos por estos autores.
Con respecto a estos métodos, la mayoría clasifica la obra como cervantina; sin embargo, es recomendable ampliar el corpus utilizado para el estudio e incluir más autores para la comparación.

Palabras clave: análisis discriminante, árboles de clasificación, máquinas de aprendizaje, regla de Bayes, regresión logística, validación cruzada.


Abstract

In this paper, some classification methods are applied to a set of texts with the aim of studying the probability that the book Novela de la tía fingida has been written by Miguel de Cervantes. This novel has been historically attributed to him but there are some encountered positions about this. The methods used in this paper range from: logistic regression, additive logistic regression, linear, quadratic, regularized, mixture and flexible discriminant analysis, classification tree, k-nearest neighbour, Naive Bayes method and support vector machines.
Methods were trained and applied using a corpus of authors contemporary to Cervantes as Lope de Vega, Jerónimo de Pasamonte, Alonso Fernández de Avellaneda, Mateo Alemán, and Francisco de Quevedo and more than forty variables, mainly words and punctuation marks, measured over written texts by these authors.
Respect to these methods, most of them classify the novel as another Cervantes work; however, is our recommendation to include more texts from these authors and more authors.

Key words: Bayes rule, Classification tree, Cross validation, Discriminant analysis, Logistic regression, Machine learning.
