Areas of assessment include training program, teaching and learning activities, capacity of graduate student, and the reputation of the university in society. This research studies the characteristics of the survey dataset structures to form data variables and analyzes the relations between data variables to build non-spatial and temporal multidimensional model (nSTM), applies the establishment of visual graphs according to the data variables representing the datasets with vertical bars indicating the values of the data variables being visually represented. This research conducts experiments on the dataset structures surveying the areas of a university. With this scientific approach, it will help university administrators to build policies to improve in all aspects and especially improve the quality of university education. <\/jats:p>","DOI":"10.1142\/s2196888823500082","type":"journal-article","created":{"date-parts":[[2023,6,29]],"date-time":"2023-06-29T07:14:10Z","timestamp":1688022850000},"page":"463-483","source":"Crossref","is-referenced-by-count":1,"title":["A Visual Analytics Approach Applying for Discovering Knowledge from Multivariate Datasets of Stakeholders Feedback in the University"],"prefix":"10.1142","volume":"10","author":[{"given":"Dang Van","family":"Pham","sequence":"first","affiliation":[{"name":"Faculty of Information Technology, Nguyen Tat Thanh University, Ho Chi Minh City, Vietnam"},{"name":"Graduate University of Science and Technology, Vietnam Academy of Science and Technology, Hanoi, Vietnam"},{"name":"Institute of Applied Mechanics and Informatics, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bao Khang","family":"Nguyen","sequence":"additional","affiliation":[{"name":"British International School, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2023,7,26]]},"reference":[{"key":"S2196888823500082BIB001","volume-title":"Illuminating the Path the Research and Development Agenda for Visual Analytics","author":"Thomas J.
