Abstract: [Purpose/Significance] Digital humanities platform, as an component of infrastructure which provides study materials for humanities scholars in various disciplines, is the carrier of digital research methods. It can contribute to the enrichment of digital humanities methodological system and the establishment of a new research paradigm of digital humanities. [Design/Methodology] This paper investigated the characteristics of digital humanities, and proposed a paradigmatic framework for humanities research.With the consideration of the projects and papers presented in domestic digital humanities annual meetings, the construction of the Chinese digital humanities resource platforms was discussed, which emphasized the functional requirements and development trends. Finally, by taking the Digital Humanities Platform of Shanghai Library as an example, applications of the thoughts and ideas were illustrated. [Findings/Conclusion] The digital humanities platform is divided into literature layer, data layer, interface layer, tool layer and presentation layer. According to the methodological characteristics of Chinese digital humanities, this paper summarizes different types of platforms. It also puts forward some design principles on how digital humanities platforms can have advanced systems, complete resources, comprehensive functions, abundant tools and user-friendliness. [Originality/Value] This paper proposes a research paradigm of digital humanities consisting of technology, process and behavior. In the digital humanities platforms, the combination of the three aspects with humanities resources are the basic components of the digital humanities research infrastructure. In addition to the focus on the technical architecture, it is also necessary toextract the content architecture featured by domain knowledge specially for design and implementation. Besides, the best practices of implementation with semantic technology（knowledge graph）have been discussed.
