Esta tesis presenta diversas contribuciones en los campos de la clasificaci\u00f3n autom\u00e1tica de texto, traducci\u00f3n autom\u00e1tica y traducci\u00f3n asistida por ordenador bajo el marco estad\u00edstico. en clasificaci\u00f3n autom\u00e1tica de texto, se propone una nueva aplicaci\u00f3n llamada clasificaci\u00f3n de texto biling\u00ed\u00bce junto con una serie de modelos orientados a capturar dicha informaci\u00f3n biling\u00ed\u00bce. Con tal fin se presentan dos aproximaciones a esta aplicaci\u00f3n; la primera de ellas se basa en una asunci\u00f3n naive que contempla la independencia entre las dos lenguas involucradas, mientras que la segunda, m\u00e1s sofisticada, considera la existencia de una correlaci\u00f3n entre palabras en diferentes lenguas. La primera aproximaci\u00f3n di\u00f3 lugar al desarrollo de cinco modelos basados en modelos de unigrama y modelos de n-gramas suavizados. Estos modelos fueron evaluados en tres tareas de complejidad creciente, siendo la m\u00e1s compleja de estas tareas analizada desde el punto de vista de un sistema de ayuda a la indexaci\u00f3n de documentos. La segunda aproximaci\u00f3n se caracteriza por modelos de traducci\u00f3n capaces de capturar correlaci\u00f3n entre palabras en diferentes lenguas. En nuestro caso, el modelo de traducci\u00f3n elegido fue el modelo m1 junto con un modelo de unigramas. Este modelo fue evaluado en dos de las tareas m\u00e1s simples superando la aproximaci\u00f3n naive, que asume la independencia entre palabras en differentes lenguas procedentes de textos biling\u00ed\u00bces. en traducci\u00f3n autom\u00e1tica, los modelos estad\u00edsticos de traducci\u00f3n basados en palabras m1, m2 y hmm son extendidos bajo el marco de la modelizaci\u00f3n mediante mixturas, con el objetivo de definir modelos de traducci\u00f3n dependientes del contexto. Asimismo se extiende un algoritmo iterativo de b\u00fasqueda basado en programaci\u00f3n din\u00e1mica, originalmente dise\u00f1ado para el modelo m2, para el caso de mixturas de modelos m2. Este algoritmo de b\u00fasqueda n<\/p>\n
