How to improve the accuracy of Lingua::NamedEntity ?

[Anonymous Monk]

Rencently I am working with Lingua::NamedEntity which is a modules in CPAN . 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', ... },

but i find that the result is not very well,especially when the module read a text having "Monday,Tuesday "and so on it will regard these words as person,who can help me thankyou very much.

I have a vague idea of what you are asking for, but instead of second-guessing, I'll offer some friendly advice:
1. Please read How (Not) To Ask A Question
2. Please wrap any code in <code> tags when posting.
3. Please read How (Not) To Ask A Question
4. Please post a sample of your current code that isn't giving the desired result.
5. Please read How (Not) To Ask A Question
6. Please ask a specific question, if you have one (I know what I mean. Why don't you?)
7. Finally, please read How (Not) To Ask A Question

   Update: Oh, and:

8. Please post questions in Seekers of Perl Wisdom, not Perl Monks Discussion
9. Please try to use a meaningful title for your question.
10. Please have a read of The Perl Monks Guide to the Monastery

Update 2:

Okay, having said all the above - you could simply do something like this:

#!/usr/bin/perl -w
use strict;
use Lingua::EN::NamedEntity;

$/ = undef;
my $text = <DATA>;

my @entities = extract_entities($text);
my @unwanted_entities = qw( Monday Tuesday Wednesday Thursday Friday S
+aturday
        Sunday);

for (@entities) {
    my $entity = ${$_}{entity};
    if ( grep { $_ eq $entity } @unwanted_entities ) {
        print "Skipping unwanted entity: $entity\n";
    }
    else {
        print "Valid entity: $entity\n"
    }
}

And the data for the above code was taken from a "recent BBC News story". The output is as follows:

Valid entity: Mr Murakami
Valid entity: Takafumi Horie
Valid entity: Singapore
Valid entity: Mr Horie
Valid entity: Societe General Asset Management
Valid entity: Asset Management
Skipping unwanted entity: Friday
Valid entity: Tokyo Stock Exchange
Valid entity: Livedoor
Valid entity: Yoshiaki Murakami
Valid entity: Murakami
Valid entity: Tokyo
Valid entity: International Trade and Industry Ministry
Valid entity: Akio Yoshino

Cheers,
