Abstract: Query-Focused Summarization (QFS) is a special area of automatic summarization, which can be used to extract valuable summary information from original document or multi-documents based on the user's personalized query requirements. The technology has been widely used in the search engine, intelligent information retrieval, Q&A system and other areas, and has received more and more attention. In this paper, we start from the typical technical framework for achieving this task, compare and analyze the existing research methods in three aspects:query comprehension, document processing and information organization, and summarize the challenges and development trends QFS. |
