NAME ^

Text::NLP::Stanford::EntityExtract - Talks to a stanford-ner socket server to get named entities back

VERSION ^

Version 0.06

Quick Start: ^

METHODS

new ( host => '127.0.0.1', port => '1234' debug => 0|1|2);

The debug flag warns the length of the text sent to the server if set to 1 and shows the actual text as well as the length if set to > 1.

server

Gets the socket connection. I think that the ner server will only do one line per connection, so you want a new connection for every line of text.

get_entities(@txt)

Grabs the tagged text for an arbitrary number of paragraphs of text, and returns as the ner tagged text.

_process_line ($line)

processes a single line of text to tagged text

entities_list($tagged_line)

returns a rater arcane data structure of the entities from the text. the position of the word in the line is recorded as is the entity type, so that the line of text can be recovered in full from the data structure.

TODO: This needs some utility subs around it to make it more useful.

list_entities ($self->entities_list($line)

Lists the entities contained within a line based from the data structure provided by entities_list($line).

If passed a list of entities it adds to that list, including counts of the numbes of each entity already found.

The data structure returns looks like this:

 $list_data = {
    'LOCATION' => {
        'Outer Mongolia' => 1,
        'Location Location Location' => 1,
        'Chinese Mainland' => 1,
        'Britney' => 1
    },
    'O' => {
        'may have returned from the' => 1,
        'said from his home in' => 1,
        '. Test a three word entity' => 1,
        'faith that she follows . Now she is attempting , for a second time , to persuade' => 1,
        '. There is a question that' => 1,
        'blah blah' => 1,
        'to the controversial' => 1,
        '.' => 1,
        'to follow suit , reports said .' => 1
    },
    'PERSON' => {
        'Bruce Lee' => 1,
        'Gwyneth Paltrow' => 1,
        'Lord Lucan' => 1
    },
    'MISC' => {
        'Jewish-based' => 1
    }
 };
