Core Viewpoint - The revision of the "China Historical Atlas," initiated under the leadership of the late historian Tan Qixian, aims to update this essential scholarly resource, reflecting advancements in historical geography, archaeology, and related fields since its first publication in 1982 [1]. Group 1: Project Overview - The revision work of the "China Historical Atlas" has been launched in Shanghai and is expected to take ten years to complete [1]. - The project will utilize the latest national basic geographic information data as a base map for rigorous verification and supplementation [1]. Group 2: Content Enhancements - The updated atlas will include new content related to the origins of early Chinese civilization and a volume on the "Republic of China period" [1]. - The project aims to create an intelligent platform to offer an online version of the atlas [1]. Group 3: Academic and Educational Goals - Fudan University will treat this revision as a leading project to strengthen the construction of new liberal arts, aiming to produce high-quality academic and educational outcomes [1]. - The initiative emphasizes a rigorous academic attitude and innovative spirit to create a work that honors the past, the present, and the nation [1].

Core Viewpoint - The article discusses the development of OpenNovelty, an automated novelty analysis system designed to enhance the academic review process by providing verifiable evidence for claims of novelty in research papers [4][25]. Group 1: System Overview - OpenNovelty is a collaboration between Fudan University's NLP research team and the academic search platform WisPaper, aimed at addressing the challenges of assessing novelty in academic submissions [4]. - The system emphasizes the need for verifiable evidence when judging the novelty of a paper, requiring that any claim of insufficient novelty be supported by traceable evidence from published literature [7][25]. Group 2: Analysis Process - The analysis process consists of four steps: 1. Core information extraction from the paper's title, abstract, and introduction [9]. 2. Literature retrieval and filtering to generate a candidate set of relevant papers [11]. 3. Hierarchical analysis and evidence comparison to assess the novelty claims [14]. 4. Generation of a novelty investigation report that consolidates findings and provides traceable evidence [20][21]. Group 3: System Functionality - The system utilizes a query expansion mechanism to generate multiple semantically equivalent variations of extracted information, ensuring comprehensive literature retrieval [7]. - It categorizes the comparison results into three outcomes: can refute, cannot refute, and unclear, based on the evidence found [15][17][19]. Group 4: Impact and Utility - OpenNovelty serves as an auxiliary tool for reviewers, helping them navigate the literature landscape and focus on critical aspects of the review process [26]. - For authors, it acts as a self-check tool to verify the novelty of their research and identify any overlooked relevant literature [27]. - The system aims to provide a verifiable path for novelty assessment, enhancing accountability in academic publishing [27]. Group 5: Limitations and Future Directions - The team acknowledges the system's limitations, emphasizing that it is a supportive tool rather than a decision-making entity, with final judgments still resting with human reviewers [29][30]. - OpenNovelty is positioned as a third-party auditing system, intended to clarify evidence during the final decision-making phase of the review process [31].

Group 1 - The annual meeting of Fudan University EMBA Alumni Association highlighted the theme "Economic Stability and Reform Breakthroughs" presented by Zhou Hanmin, emphasizing the development path for macroeconomics and technological innovation during the 14th Five-Year Plan [1] - Zhou pointed out that high-level openness should focus on five capabilities: institutional openness, supply chain governance, technological innovation openness, digital trade development, and participation in global governance [1] - Chinese enterprises are transitioning from "going out" to "going in," seeking symbiotic relationships in different civilizational and institutional contexts, reflecting China's institutional openness [1] Group 2 - Fudan University and the University of Washington's Foster School of Business EMBA program ranked first globally in the Financial Times 2025 EMBA rankings, while Fudan University's EMBA program ranked in the top eight globally and has maintained the top position among Chinese programs for four consecutive years [2]
