Humankind, the dominant species on Earth, faces the most significant mission; we must endeavor on a global scale to perpetually restore and improve our natural environments. It is important to realize global environmental computing methodology for analyzing natural phenomena and influences of nature and livings in a context dependent way with a large amount of information resources in global environments.We have presented a \u201cSemantic Computing System\u201d [1,2,3] for analyzing and interpreting the meanings of concepts, objects and phenomena, applied to natural environment-analysis and changes occurring in the world. As a global environmental system based on the semantic computing system, we have realized \u201c5-Dimensional World Map System(5D World Map System)\u201d [4,7,10] for integrating, analyzing, retrieving and visualizing environmental situations in oceans and landsThe 5D World Map System is globally utilized as a Global Environmental Semantic Computing System, in SDG-14, United Nations-ESCAP (https:\/\/sdghelpdesk.unescap.org\/toolboxes). We have also proposed the concept of \u201cSemantic-SPA (Sensing, Processing and Analytical Actuation Functions)\u201d for realizing a global environmental system, to apply it to 5-Dimensional World Map System [4,7,10]. This concept is significant to design environmental systems with Cyber-Physical space-integration to detect environmental phenomena as real data resources in a physical-space (real space), map them to cyber-space with semantic computing, and propagate the analytical computing results to the physical-space with visualization for expressing environmental situations, phenomena, causalities and influences. It is also significant to memorize the situations and compute environmental changes in various contexts, in order to discover what are happening in the nature of our planet. We have various (almost infinite) aspects and contexts in environmental changes in our planet, and it is essential to realize a new analyzer for computing differences in those situations for discovering actual aspects and contexts in nature.<\/jats:p>","DOI":"10.3233\/faia251715","type":"book-chapter","created":{"date-parts":[[2026,2,13]],"date-time":"2026-02-13T09:53:24Z","timestamp":1770976404000},"source":"Crossref","is-referenced-by-count":0,"title":["A SPA-Based Semantic Computing System for Natural Environment-Analysis and Visualization with \u201c5-Dimensional World-Map System\u201d"],"prefix":"10.3233","author":[{"given":"Yasushi","family":"Kiyoki","sequence":"first","affiliation":[{"name":"Faculty of Data Science, Musashino University, Japan"},{"name":"SFC Research Institute, Keio University, Japan, kiyoki@sfc.keio.ac.jp"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Information Modelling and Knowledge Bases XXXVII"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA251715","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,13]],"date-time":"2026-02-13T09:53:24Z","timestamp":1770976404000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA251715"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,2,12]]},"ISBN":["9781643686462"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia251715","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,2,12]]}}}
