When building Hypermedia/Web Applications, (different) designers are often faced with the same problems over and over again. Those recurring problems soon yield elegant solutions, which can be conveniently described as design patterns. In this paper we present two patterns for (Adaptive) Web Applications that refine the navigation structure of the application, based on use of the web applicatio...

This paper introduces JWN-Br – an API for Wordnet.br. Developed in Java, JWN-Br is responsible for (i) providing direct access to Wordnet.br, structuring its data as Java objects; (ii) abstracting away Wordnet.br’s internal codification, making its use easier to the programmer; and (iii) giving room for the local augmentation of Wordnet.br’s original data set. Distributed under GPL, JWN-Br is a...
