Fuzzy Ontology-based Spatial Data Warehouse for Context-aware Search and Recommendation

Hajer Baazaoui-Zghal
2016 Proceedings of the 11th International Joint Conference on Software Technologies  
The need to build a spatial data warehouse over all structured and unstructured data is becoming necessary in many fields.  ...  In this paper, we propose a fuzzy Ontology-based Spatial Data Warehouse for contextual search and recommendation, composed of 3 main layers: (1) Data layer composed of structred, unstructred and users  ...  We recall that the main steps of data warehouse design starting from heterogeneous sources are: conceptual design, logical design and physical design.  ...

Fuzzy Ontology-based Approach for the Requirements Query Imprecision Assessment in Data Warehouse Design Process near Negative Fuzzy Operator

LARBI Abdelmadjid, MALKI Mimoun, BOUKHALFA Kamel
2018 International Journal of Information Technology and Computer Science  
In order to evaluate the expression in decision-making requirements and in order to improve the data warehouses design quality, this paper presents a rigorous fuzzy ontologybased solution.  ...  We limit our study, in this paper to the "Near negative" operator case. To the best of our knowledge, this case has not been addressed yet in the data warehouse context.  ...  Ontology-based data warehouse design Before starting this part, we note that the majority of DW vagueness studies, focuses on data inaccuracies and offer structural solutions.  ...
