- Abstract
- This paper proposes an approach for relaxing constraints of
a pictorial query when the answer
returns a null value. In particular this approach, similarl
y with the 9-intersection matrix between two sets
point, proposes to extend the representation of the symboli
c graphical objects (SGO) in terms of interior,
boundary, and complement points, applied to any configurati
on of two SGO. The suggested method considers
three matrices: the first for representing the points cardin
ality of the intersection of interior, boundary and
exterior of a polyline with the analogous three intersectio
ns of a polygon, the second for representing the
polylines cardinality of the same intersection sets and the
third for representing the polygons cardinality of
the same intersection sets. Moreover, in order to relax topo
logical constraints of any configuration, conceptual
neighbourhood graphs between topological operators valid
for the different pairs of SGO are proposed, as well
as the connected complex matrices which enlarge the above me
ntioned 9-intersection matrix. A computational
model for determining relations that are conceptually more
similar for each configuration is also proposed
and the polyline-polygon relation is studied. (literal)
