Abstract : The paper presents novel ideas on spatial reasoning by considering shape and size of spatial entities and focuses on extension of conventional models: Cone-Shaped and Minimum Boundary Rectangle (MBR). Firstly, it goes on the use of how well MBR features fixed to cone-shaped model considering the relative extension of the spatial entities. This suggests the further possibility and the quality of combinatorial study of the models in spatial reasoning. Secondly, another model is proposed by referencing a unique common point set (of two entities) instead of using one out of two entities (referencing in a conventional way). This makes model robust and more symmetric as it reserves two way relationships from the unique reference point set. Further, it gives flexibility to utilize conventional models. Finally, it gives a comparative idea of proposed models among existing ones.
