NAME

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

CONTENTS

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.

The hash also includes the number of occurrences for that entity.

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

    extract_entities

Pass to <extract_entities> a text, and it will return a list of entities, as described above.
