Abstract
The problem of searching the set of keys in a file to find a key which is closest to a given query key is discussed. After “closest,” in terms of a metric on the the key space, is suitably defined, three file structures are presented together with their corresponding search algorithms, which are intended to reduce the number of comparisons required to achieve the desired result. These methods are derived using certain inequalities satisfied by metrics and by graph-theoretic concepts. Some empirical results are presented which compare the efficiency of the methods.

An intersection inequality sharper than the tanimoto triangle inequality for efficiently searching large databases.

TL;DR: A new intersection inequality is derived which provides a bound on the Tanimoto similarity between two fingerprint vectors and it is shown that this bound is considerably sharper than the bound associated with the triangle inequality of the TAnimoto distance.

An index data structure for searching in metric space databases

TL;DR: Empirical results show that the EGNAT is suitable for conducting similarity searches on very large metric space databases, and it is shown that this data structure allows efficient parallelization on distributed memory parallel architectures.

Symbolic Gray Code as a Perfect Multiattribute Hashing Scheme for Partial Match Queries

TL;DR: This paper proposes a new hashing scheme, called bucket-oriented symbolic Gray code, which can be used to produce any arbitrary Cartesian product file, which has been shown to be good for partial match queries.
