Métodos de Otimização Combinatória Aplicados ao Problema de Compressão MultiFrases
The Internet has led to a dramatic increase in the amount of available information. In this context, reading and understanding this flow of information have become costly tasks. In the last years, to assist people to understand textual data, various Natural Language Processing (NLP) applications based on Combinatorial Optimization have been devised. However, for MultiSentences Compression (MSC)...
متن کاملUm Levantamento de Métodos de Avaliação de Arquiteturas de Software Específicas
A diversity of methods to software architecture evaluation has been proposed, aiming at the quality of software systems. Efforts to identify, analyse and compare these methods can be also found. However, a more recent study has not been conducted. Thus, in this paper, we aim at identifying methods to evaluate recent and specific architectures — reference architectures, service-oriented architec...

People with physical disabilities may have serious problems to use computer keyboards to write. For this reason, they may use specific tools that include systems to assist the writing process, such us word prediction, in order to reduce the number of keystrokes needed to write the text. Word prediction may be based on different sources of information: statistical, grammatical, specific of the s...
متن کاملAnálisis y comparación de diferentes métodos de reconstrucción de árboles semánticos
The addressing of natural language processing tasks by modern techniques, inspired in deep learning, rely on different pre-training stages. Nevertheless, some problems need an additional processing, after the referred scenarios, because of the complexity they exhibit. Structuring of semantic trees is one of the most prolific methods in the literature for this purpose. In this paper we compare t...
