What will Semantic Web research focus on in 20 years from now? We asked this question to the community and collected their visions in the "Next 20 years" track of ESWC 2023. We challenged the participants to submit "future" research papers, as if they were submitting to the 2043 edition of the conference. The submissions - entirely fictitious - were expected to be full scientific papers, with research questions, state of the art references, experimental results and future work, with the goal to get an idea of the research agenda for the late 2040s and early 2050s. We received ten submissions, eight of which were accepted for presentation at the conference, that mixed serious ideas of potential future research themes and discussion topics with some fun and irony. In this paper, we intend to provide a survey of those "science fiction" papers, considering the emerging research themes and topics, analysing the research methods applied by the authors in these very special submissions, and investigating also the most fictitious parts (e.g., neologisms, fabricated references). Our goal is twofold: on the one hand, we investigate what this special track tells us about the Semantic Web community and, on the other hand, we aim at getting some insights on future research practices and directions.

翻译：20年后语义网研究将聚焦于哪些主题？我们向学术界提出了这一问题，并在ESWC 2023的"未来20年"专题中征集了学者们的愿景。我们邀请参与者提交"未来"研究论文，仿佛他们是在向2043年的会议投稿。这些完全虚构的投稿需具备完整科学论文的要素，包括研究问题、最新技术参考文献、实验结果及未来工作，旨在勾勒21世纪40年代末至50年代初的研究议程。我们共收到十篇投稿，其中八篇被接收用于会议展示。这些论文将潜在未来研究主题与讨论热点的严肃构想，与趣味性和反讽性巧妙结合。本文旨在综述这些"科幻"论文，梳理新兴研究主题与议题，分析作者在这些特殊投稿中采用的研究方法，并考察最具虚构性的部分（如新造术语、虚构参考文献）。我们的目标有二：其一，探究这一特殊专题如何反映语义网社群的特征；其二，旨在获取对未来研究实践与研究方向的启示。
