民国学人书信承载着民国学人历史记忆和学术精神，具有深厚的历史与文化价值。但在当下，民国学人书信资源组织与服务方式传统单一，存在资源管理封闭与保存分散的问题与挑战，针对书信资源数字化开发程度较浅，揭示粒度有待精细，由于缺乏语义描述与关联，难以适应数字时代下资源需求变化，此类资源现状亟待改善。伴随着科学技术与传统文化领域融合趋势的不断深入与发展，语义网、关联数据等信息技术在数字时代为民国学人书信资源实现语义关联与聚合提供了新思路。

本文在梳理关联数据、资源聚合相关理论研究和应用实践的基础上，结合民国学人书信资源的特点，立足民国学人书信资源聚合的必要性，确定资源聚合目标和流程，提出基于关联数据的民国学人书信资源聚合框架，逐层讨论了构成框架的五个层次，着重阐述了实现民国学人资源关联聚合的具体过程。依据框架，实现了基于关联数据的民国学人书信资源聚合及资源聚合服务平台的设计。

本文充分利用关联数据的技术优势，就如何实现民国学人书信资源语义聚合进行了探讨。基于书目框架核心概念模型提炼民国学人书信资源核心概念与相关资源实体类，并在不同类型资源实体之间构建语义关系，实现了学人书信资源与人、地、事、物等实体之间的互相关联，为实现民国学人书信资源关联聚合奠定了基础。基于多种视角探讨民国学人书信资源聚合模式，有助于用户全面、多维地获取民国学人书信资源相关实体信息与关联脉络。最后，通过设计与搭建民国学人书信资源聚合平台，以王重民等人书信资源为例开展了资源聚合实验，基于Drupal创建和本地发布了民国学人书信关联数据，清晰直观地展现了民国学人书信资源多维语义聚合效果。

本课题研究拓宽了学人书信资源组织研究的视野，对其聚合粒度的探讨由资源组织向知识组织推进，实现了方法上的创新，能够为用户提供多元化知识关联服务，促进了民国学人书信资源多重价值的实现。本课题研究在理论和技术层面具有一定的可复用性，可以为其他名人文化史料资源整合提供参考，同时在一定程度上丰富了我国数字人文史料资源的应用场景。此外，后续可以在此基础上进一步开展相关研究，促进更深层次的解读与利用。

The letters of the scholars of the Republic of China carry the historical memory and academic spirit, and have profound historical and cultural value. However, at present, the traditional organization and service mode of correspondence resources of scholars in the Republic of China is single, and there are problems and challenges caused by closed and decentralized resource management. In view of the shallow degree of correspondence resources digitization, the disclosure granularity needs to be refined. Due to the lack of semantic description and association, it is difficult to adapt to the changes of resource demand in the digital era, and the current situation of such resources needs to be improved. With the deepening and development of the integration trend between science and technology and traditional culture, information technologies such as Semantic Web and Linked Data provide new ideas for the realization of semantic association and aggregation of scholars' correspondence resources in the digital age.

On the basis of the theoretical research and practice related to Linked Data and resource aggregation, this paper comprehensively analyzes the characteristics of the letter resources of the Republic of China, based on the necessity of the aggregation of the letter resources of the scholars of the Republic of China, determines the objectives, principles and processes of resource aggregation, and then proposes the overall framework for realizing the aggregation of the letter resources based on the Linked Data, discusses the five levels constituting the framework layer by layer. According to the framework, this paper focuses on the process of realizing the association and aggregation of letter resources of scholar in the Republic of China and the design of resource aggregation service platform of scholars in the Republic of China based on Linked Data.

This paper makes full use of the technical advantages of Linked Data to realize the semantic aggregation of letter resources. Based on the core concept model of BIBFRAME, the core concepts and related resource entity classes of scholar's letter resources in the Republic of China are refined, and semantic relationships are constructed between different types of resource entities, which realizes the correlation between letter resources and entities such as people, places, things and things, and lays a foundation for the association and aggregation of letter resources. This paper discusses the aggregation modes of letter resources of scholars in the Republic of China from a variety of perspectives, which is helpful for users to comprehensively obtain the relevant entity information and context with multi-dimension. Finally, through the design and construction of the Republic of China scholars' letter resource aggregation platform, taking the letter resources of Wang Zhongmin and others as an example, author carries out the letter resource aggregation experiment, creates and locally releases the letter Linked Data based on Drupal, which clearly and intuitively shows the multi-dimensional semantic aggregation effect of the Republic of China scholars' letter resources.

This research broadens the research vision of scholars' letter resource organization, promotes the discussion of its aggregation granularity from resource organization to Knowledge Organization, realizes the innovation of methods, provides users with corresponding knowledge association services, and promotes the realization of multiple values of the Republic of China scholars' letter resources. This research has certain reusability at the theoretical and technical levels, which can provide reference for the integration of other celebrity cultural and historical resources, and enrich the application scenarios of digital humanities historical resources in China to a certain extent. In addition, the follow-up can further carry out relevant research on this basis to promote deeper interpretation and utilization.
