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.
