| A simplex-based enriched graph data model combining a discrete and place-based indoor spatial model with a location-based social network (LBSN) is presented in this research. The proposed model integrates similarity and relevance indicators from Q-analysis of simplicial complexes, allowing for easier data manipulation and discovering latent relationships in an LBSN. The proposed model also employs an indoor-specific metric measuring ease of access between pairwise indoor places to analyze spatial-social queries in indoor spaces. The experimental implementation of the proposed model demonstrates the quantitative efficiency of adopting graph-based representation as well as the qualitative excellence of simplex-based enrichment in processing spatial-social queries in indoor spaces, as shown in the results. |
