Connor, R., Vadicamo, L., Rabitti, F.: “High-Dimensional Simplexes for Supermetric Search”. In Proceedings of SISAP 2017, Springer International Publishing (Lecture Notes in Computing Science),pp. 96-109, October 2017
In a metric space, triangle inequality implies that, for any three objects, a triangle with edge lengths corresponding to their pairwise distances can be formed. The n-point property is a generalisation of this where, for any (n+1) objects in the space,...

Metric indexing research is concerned with the efficient evaluation of queries in metric spaces. In general, a large space of objects is arranged in such a way that, when a further object is presented as a query, those objects most similar to the query...
