Description

Community-Based Korean Settlement Support System and Method of Operating the Same The present invention relates to the field of information processing system technology for providing guidance information tailored to individual settlement situations through network linkage between mobile terminals and servers, and for integrating and managing information regarding public institutions such as administration, welfare, education, and medical services, as well as private institutions related to settlement support, community spaces, and living convenience facilities, for foreigners and migrants wishing to settle in Korea. In particular, the invention relates to a community-based Korean settlement support system and its operation method, which efficiently supports the search for and decision-making regarding settlement support institutions throughout the entire process from the initial to the long-term settlement stage in Korea by calculating evaluation indicators, priorities, and recommendation types based on user communities, and generating and providing personalized guidance information based on these factors, by integrally managing and analyzing settlement profile data received from user terminals, such as settlement stage, purpose of stay, preferred language, and current location, along with accumulated existing user feedback history data and usage statistics data for each settlement support candidate item on the server side, and generating and providing personalized Korean settlement support guidance information based on these factors. Unless otherwise indicated in this specification, the contents described in this section are not prior art for the claims of this application, and are not to be recognized as prior art simply because they are included in this section. Generally, individuals staying in Korea for a certain period—such as foreign residents, international students, overseas Koreans, and migrant workers—continuously encounter various administrative and public support agencies regarding the management of their residency status, registration procedures, securing housing, employment and entrepreneurship, education and care, and the use of medical and welfare services after entry. Traditionally, foreigner portals of central government agencies, websites of immigration offices, integrated call centers, web pages of local government multicultural family support centers and foreign resident support centers, private legal and labor counseling services, and websites of counseling centers operated by religious or civic groups were established separately. This presented a problem in that it is difficult for users hoping to settle in Korea to identify, at a glance, the agency that best suits their purpose of stay, stage of settlement, preferred language, and current residential area. In particular, despite differences in service targets, required documents, operating hours, reservation methods, and language support ranges among agencies, the lack of an integrated guidance system that systematically compares and organizes this information results in inefficiency, forcing users to repeatedly search through multiple websites and notices. Meanwhile, conventional public information provision systems often provide information on administrative agencies and settlement support organizations primarily in the form of brochures, PDF guides, and static web pages. Such static data has limitations; it is difficult to promptly reflect changes such as policy shifts, adjustments to operating hours, changes in responsible departments, or the opening and closing of centers, and it fails to reflect user experience data, such as waiting times, congestion levels, and consultation quality at the actual site. Furthermore, existing online map services and general store review services often follow classification systems centered on restaurants, shops, and commercial facilities. Consequently, it is difficult to organize and present settlement support-related organizations—such as immigration offices, foreign resident centers, public counseling centers, and free legal counseling centers—from a separate perspective. Additionally, these systems are structurally unsuitable for users to filter and find appropriate organizations based on criteria such as visa type, purpose of stay, or preferred language. Furthermore, existing immigrant and compatriot communities that have already settled in Korea frequently voluntarily share daily life information and reviews of institutions through messenger rooms, social networking service groups, and online bulletin boards. While the information shared on these community channels has the advantage of reflecting on-site situations relatively quickly and including details not found in official documents—such as the actual response attitude of specific institutions or language communication capabilities—it also has limitations. Due to the structure where posts accumulate in chronological order, the same ques
