Resumo


O avanço nos sistemas de Question Answering alcançou resultados importantes e novos problemas relacionados, como Complex Question Answering e Knowledge Base Question Answering, surgiram. No entanto, faltam estudos que analisam o problema e abordagens para Complex Knowledge Base Question Answering (C-KBQA). Este trabalho preenche essa lacuna apresentando uma visão geral do C-KBQA. Uma coleção de 54 artigos foi selecionada e um mapa dos métodos, abordagens, tendências e lacunas sobre C-KBQA foi realizado. É mostrado que as questões de múltiplos saltos e restritivas são os dois tipos de questões abordadas na literatura. Três etapas foram identificadas para criar um sistema C-KBQA e duas abordagens são geralmente usadas.
