  • This study aims to explore the scholarly advancements and research trends of living labs, highlighting their role as a strategic approach for addressing community challenges and driving innovation in public services through a systematic investigation of domestic academic research. A total of 510 research papers published between 2012 and 2024 were analyzed, focusing on unstructured data such as titles, abstracts, and keywords. Using text mining techniques, the underlying themes were systematically extracted and refined through Latent Dirichlet Allocation(LDA) topic modeling and semantic network analysis, leading to the identification of five core themes: 'Smart cities and participatory innovation', 'Community welfare and social innovation', 'User-driven field-Based innovation', 'Educational innovation linked to community issues', and 'Enhancement of quality of life, culture, and youth welfare'. Each theme was named based on high-frequency terms within topic clusters and further verified through a detailed literature review, ensuring the thematic categories accurately reflect the focus of the papers. Semantic network analysis further revealed the structural interconnections between keywords, adding depth to the understanding of their unique characteristics. The findings present a comprehensive view of the research landscape in living lab studies, highlighting thematic convergence and divergence across various scholarly focuses. This study provides actionable insights for academics and policymakers, suggesting that living labs can serve as a strategic framework for solving regional challenges, enhancing community resilience, and integrating digital solutions into public services and lays the foundation for future research and policy initiatives aimed at leveraging living labs for sustainable community innovation.

  • Aside from serving as a body that monitors and criticizes the government through reviews and comments on public issues, newspapers can also form and spread public opinion. Metadata contains certain picture records and, in the case of local newspapers, the former is an important means of obtaining locality. Furthermore, advertising in newspapers and the way of editing in newspapers can be viewed as a representation of the times. For the value of archiving in newspapers when a documentation strategy is established, the newspaper is considered as a top priority that should be collected. A newspaper archive that will handle preservation and management carries huge significance in many ways. Journalists use them to write articles while scholars can use a newspaper archive for academic purposes. Also, the NIE is a type of a practical usage of such an archive. In the digital age, the newspaper archive has an important position because it is located in the core of MAM, which integrates and manages the media asset. With this, there are prospects that an online archive will perform a new role in the production of newspapers and the management of publishing companies. Korea Integrated News Database System (KINDS), an integrated article database, began its service in 1991, whereas Naver operates an online newspaper archive called "News Library." Initially, KINDS received an enthusiastic response, but nowadays, the utilization ratio continues to decrease because of the omission of some major newspapers, such as Chosun Ilbo and JoongAng Ilbo, and the numerous user interface problems it poses. Despite these, however, the system still presents several advantages. For example, it is easy to access freely because there is a set budget for the public, and accessibility to local papers is simple. A national library consistently carries out the digitalization of time-honored newspapers. In addition, individual newspaper companies have also started the service, but it is not enough for such to be labeled an archive. In the United States (US), "Chronicling America"-led by the Library of Congress with funding from the National Endowment for the Humanities-is in the process of digitalizing historic newspapers. The universities of each state and historical association provide funds to their public library for the digitalization of local papers. In the United Kingdom, the British Library is constructing an online newspaper archive called "The British Newspaper Archive," but unlike the one in the US, this service charges a usage fee. The Joint Information Systems Committee has also invested in "The British Newspaper Archive," and its construction is still ongoing. ProQuest Archiver and Gale NewsVault are the representative platforms because of their efficiency and how they have established the standardization of newspapers. Now, it is time to change the way we understand things, and a drastic investment is required to improve the domestic and international online newspaper archive.
