Using CBR for Portuguese Question Generation
In this paper, we propose a new architecture for Question Generation for the Portuguese Language. This architecture aims at the automatic generation of questions, to be used later, for instance, in automatic question answering by means of predictive question generation. Our approach combines a case-based reasoning system and a module for question generation. The question generation module uses manually built rules that are fed to the case-based reasoning engine for selecting which ones should be used. This is accomplished by comparing the answer and the sentence part-of-speech tag sequences. An identical tag sequence on sentences and answers usually implies a similar sequence on the corresponding questions. We discuss the details of this architecture, how it performs and the results obtained so far.
