pg_similarity is an extension to support similarity queries on PostgreSQL. The
|
|
implementation is tightly integrated in the RDBMS in the sense that it defines
|
|
operators so instead of the traditional operators (= and <>) you can use ~~~
|
|
and ! (any of these operators represents a similarity function).
|
|
|
|
pg_similarity has three main components:
|
|
|
|
* Functions: a set of functions that implements similarity algorithms available
|
|
in the literature. These functions can be used as UDFs and, will be the base
|
|
for implementing the similarity operators;
|
|
* Operators: a set of operators defined at the top of similarity functions. They
|
|
use similarity functions to obtain the similarity threshold and, compare its
|
|
value to a user-defined threshold to decide if it is a match or not;
|
|
* Session Variables: a set of variables that store similarity function
|
|
parameters. Theses variables can be defined at run time.
