  Current article is an extended version of a paper presented at the ITDRR-2023 conference on the spatiotemporal archiving of Greek tweets regarding the 2015 Middle Eastern refugee waves and related war conflicts. The paper further explores the spatial factor. Specifically, a semi-fuzzy approach based on Machine Learning and GIS is introduced. Location Entity Recognition (LER) using a transformer, geocoding, extensive GIS processing for geolocation extraction, Latent Dirichlet Allocation (LDA) models, and Support Vector Machine (SVM) classification were combined, creating an innovative methodology. Both the temporal aspect (Phase 1) and the spatial aspect (Phase 2) were examined through subsets generated from locations refered to specific countries. In total, 1,780 topics (Phase 1, temporal factor) and 1,131 topics (Phase 2, spatial factor) were generated from temporal and spatial subse.. Read More»
