Lucy Overview

Lucy is an Entity Recognition engine which defines a simple yaml syntax for recognizing entities in text.

Core concept

Lucy's core concept is that:

Entities are cascading patterns of tokens and entities.

Lucy focuses on capturing your knowledge by focusing on token patterns.

Token patterns are a natural way of building a model, because it allows you to focus on the fragments of information you understand in way that is instantly testable and naturally builds up to more complex entities.

Key tenants

Tenant 1: Minimize concept count

Lucy has 2 core concepts:

  1. Name your Entities - name each entity in your system.
  2. Define their Patterns - Define entity patterns as simple sequences of tokens and other entities.

Tenant 2: Instant feedback

When authoring you want immediate feedback on the impact of your changes. Lucy acheives this by not requiring any training or even CLI tool to be invoked to see the results of your changes.

Tenant 3: Maximize your input

Traditional ML systems require you to "invent" many permutations of sentence structure and the laboriously label them for the system to understand your patterns.

Lucy focuses on a syntax which needs minimal changes to affect your desired outcome and maximizes the reuse.

Lucy's relationship to ML

The Lucy engine can be run on it's own and work perfectly fine, but it can also be coupled with existing LU engines such as LUIS or Orchestrator to great benefit.

  • External Entity Recognizer - Lucy can be used as a runtime source of external entities to a machine learning system such as LUIS.
  • Generate LU files - Lucy can be used to generate .LU files which can contain labeled examples and entity references.

Language support

There are 2 factors controlling language support in Lucy.

Tokenizers

Lucy uses off the shelf Lucene token analyzers to tokenize text into tokens. There are currently token analyzers for 29 lanuages:

  • Arabic Armenian Basque Catalan Chinese Czech Danish Dutch English Finnish French Galician German Greek Hindi Hungarian Chinese Japanese Korean Indonesian Irish Italian Latvian Norwegian Persian Portuguese Romanian Russian Spanish Swedish Turkish

Microsoft.Text.Recognizers

The Microsoft.Text.Recognizers libraries provide support for core entity types:

  • age boolean currency datetime dimension email guid hashtag ip mention number numberrange ordinal percentage phonenumber temperature url

Microsoft.Text.Recognizers support 15 languages

  • Arabic Bulgarian Chinese German English Spanish French Hindi Italian Japanese Korean Dutch Portuguese Swedish Turkish

See Microsoft.Text.Recognizers for a complete listing of languages and support.
