Update Summarization for Portuguese
2017 Brazilian Conference on Intelligent Systems (BRACIS)(2017)
摘要
Update summarization aims at automatically producing a summary from a collection of texts for a reader that already has some previous knowledge about the subject. It is a challenging task, since it not only brings all the demands from the summarization area (as producing informative, coherent and cohesive summaries) but also includes the issue of reporting only relevant new/updated content. In this paper, we report a comprehensive investigation of update summarization methods for the Portuguese language, for which there are few initiatives, and propose a new method that combines the summarization strategies of some other methods, producing better results and advancing the state of the art. More than this, we introduce a reference dataset and establish an experiment setup in the area in order to foster future research.
