Indexing large metric spaces for similarity search queries

Tolga Bozkaya, Meral Ozsoyoglu
1999 ACM Transactions on Database Systems  
In this paper we consider using distance-based index structures for similarity queries on large metric spaces.  ...  For example, given an image database, one may want to retrieve all images that are similar to a given query image.  ...  Because of (8), Y cannot be in the query result, which means that we do not have to check any object in the left branch.  ...

Em-K Indexing for Approximate Query Matching in Large-scale ER [article]

Samudra Herath, Matthew Roughan, Gary Glonek
2021 arXiv   pre-print
Indexing or blocking techniques reduce the search space and execution time in the ER process. However, approximate indexing techniques that scale to very large-scale datasets remain open to research.  ...  In this paper, we investigate the query matching problem in ER to propose an indexing method suitable for approximate and efficient query matching.  ...  We can apply several k-NN search methods for indexing arbitrary metric spaces; for more details, refer to the surveys [5, 15] .  ...

A geometric framework for modelling similarity search

V. Pestov
1999 Proceedings. Tenth International Workshop on Database and Expert Systems Applications. DEXA 99  
The aim of this paper is to propose a geometric framework for modelling similarity search in large and multidimensional data spaces of general nature, which seems to be flexible enough to address such  ...  Such a framework is provided by the concept of the so-called similarity workload, which is a probability metric space Ω (query domain) with a distinguished finite subspace X (dataset), together with an  ...  This could well be the case with the technique of metric transform as applied to histogram indexing for image search by colour content.  ...

Fundamentals of the problem

Edgar Chávez, Gonzalo Navarro
2010 SIGSPATIAL Special  
In a metric space coordinates are not necessarily present, thus most of the algorithms designed for coordinate spaces do not apply directly.  ...  The most basic ones are (a) range query (q, r), for q ∈ X and r ∈ R + , returns {u ∈ U, d(q, u) ≤ r}, the dataset objects at distance within r of q; and (b) k-nearest neighbor query nn(q, k), for k ∈ N  ...  Then it refers to the nested loop, where each element of a set is searched for in the other set using an index, as the basic technique, which misses opportunities for optimization due to similar queries  ...
