Modules¶

Modules are like plugins to the system, usually providing additional functionality at some cost - needs additional dependencies, supports only specific language etc. That's why they are not included into the core system, but can be easily included into your rules.

eg.

!IMPORT("rita.modules.fuzzy")

FUZZY("squirrel") -> MARK("CRITTER")

NOTE: the import path can be any proper Python import. So this actually allows you to add extra functionality by not modifying RITA's source code. More on that in Extending section

Fuzzy¶

This is more as an example rather than proper module. The main goal is to generate possible misspelled variants of given word, so that match matches more cases. Very useful when dealing with actual natural language, eg. comments, social media posts. Word you can be automatically matched by proper you and u, for as for and 4 etc.

Usage:

!IMPORT("rita.modules.fuzzy")

FUZZY("squirrel") -> MARK("CRITTER")

Pluralize¶

Takes list (or single) words, and creates plural version of each of these.

Requires: inflect library (pip install inflect) before using. Works only on english words.

Usage:

!IMPORT("rita.modules.pluralize")

vehicles={"car", "motorbike", "bicycle", "ship", "plane"}
{NUM, PLURALIZE(vehicles)}->MARK("VEHICLES")

Tag¶

Is used or generating POS/TAG patterns based on a Regex e.g. TAG("^NN|^JJ") for nouns or adjectives.

Works only with spaCy engine

Usage:

!IMPORT("rita.modules.tag")

{WORD*, TAG("^NN|^JJ")}->MARK("TAGGED_MATCH")
