• Abstract: The design or simulation analysis of special equipment products must follow the national standards, and hence it may be necessary to repeatedly consult the contents of the standards in the design process. However, it is difficult for the traditional question answering system based on keyword retrieval to give accurate answers to technical questions. Therefore, we use natural language processing techniques to design a question answering system for the decision-making process in pressure vessel design. To solve the problem of insufficient training data for the technology question answering system, we propose a method to generate questions according to a declarative sentence from several different dimensions so that multiple question-answer pairs can be obtained from a declarative sentence. In addition, we designed an interactive attention model based on a bidirectional long short-term memory (BiLSTM) network to improve the performance of the similarity comparison of two question sentences. Finally, the performance of the question answering system was tested on public and technical domain datasets.

  We propose a framework of question parsing and execution on textual QA. The proposed framework can be viewed as a top-down question parsing followed by a bottom-up answer backtracking. Our experiments on MuSiQue, 2WikiQA, HotpotQA, and NQ show that the proposed parsing and hybrid execution framework outperforms existing approaches in supervised, few-shot, and zero-shot settings.

  This work adopts the linguistic framework of Questions Under Discussion (QUD) for discourse analysis. We characterize relationships between sentences as free-form questions, in contrast to exhaustive fine-grained questions. We develop the first-of-its-kind QUD that derives a dependency structure of questions over full documents.

  We propose a novel task for knowledge-driven follow-up question generation in conversational surveys.

We then propose a two-staged knowledge-driven model for the task, which generates informative and coherent follow-up questions.
