NAME

Lingua::EN::NamedEntity - Basic Named Entity Extraction algorithm

SYNOPSIS

  use Lingua::EN::NamedEntity;
  my @entities = extract_entities($some_text);

DESCRIPTION

"Named entities" is the NLP jargon for proper nouns which represent people, places, organisations, and so on. This module provides a very simple way of extracting these from a text. If we run the extract_entities routine on a piece of news coverage of recent UK political events, we should expect to see it return a list of hash references looking like this:

  { entity => 'Mr Howard', class => 'person', scores => { ... }, },
  { entity => 'Ministry of Defence', class => 'organisation', ... },
  { entity => 'Oxfordshire', class => 'place', ... },

The additional scores hash reference in there breaks down the various possible classes for this entity in an open-ended scale.

Naturally, the more text you throw at this, the more accurate it becomes.
