Trait-oriented Programming in Java 8

International audienceJava 8 was released recently. Along with lambda expressions, a new language construct is introduced: default methods in interfaces. The intent of this feature is to allow interfaces to be extended over time preserving backward compatibility. In this paper, we show a possible, different use of interfaces with default methods: we introduce a trait-oriented programming style based on an interface-as- trait idea, with the aim of improving code modularity. Starting from the most common operators on traits, we introduce some programming patterns mimicking such operators and discuss this approach

A Resource for Detecting Misspellings and Denoising Medical Text Data

In this paper we propose a method for collecting a dictionary to deal with noisy medical text documents. The quality of such Italian Emergency Room Reports is so poor that in most cases these can be hardly automatically elaborated; this also holds for other languages (e.g., English), with the notable difference that no Italian dictionary has been proposed to deal with this jargon. In this work we introduce and evaluate a resource designed to fill this gap.In questo lavoro illustriamo un metodo per la costruzione di un dizionario dedicato all’elaborazione di documenti medici, la porzione delle cartelle cliniche annotata nei reparti di pronto soccorso. Questo tipo di documenti è così rumoroso che in genere le cartelle cliniche difficilmente posono essere direttamente elaborate in maniera automatica. Pur essendo il problema di ripulire questo tipo di documenti un problema rilevante e diffuso, non esisteva un dizionario completo per trattare questo linguaggio settoriale. In questo lavoro proponiamo e valutiamo una risorsa finalizzata a condurre questo tipo di elaborazione sulle cartelle cliniche
