Tagging Full Name in Stanford NER

问题

Im trying to tag full name as a complete tag(one person) instead of individual tags. Here is an example.

http://nlp.stanford.edu:8080/ner/process (Stanford NER online)

Example sentence: Muhammad Ali was a great boxer. Ali's greatest rival was Joe Frazier. The name can also be written as M. Ali and J. Frazier.

This is my existing PHP code`

$text = "Muhammad Ali was a great boxer. Ali's greatest rival was Joe Frazier. The name can also   be written as M. Ali and J. Frazier";

$pos = new \StanfordNLP\NERTagger(
          'XPATH/NER/StanfordNLP/stanford-ner-2013-11-12/classifiers/english.conll.4class.distsim.crf.ser.gz',
          'XPATH/NER/StanfordNLP/stanford-ner-2013-11-12/stanford-ner.jar'
);
$result = $pos->tag(explode(' ', " $text")); 

foreach ($result as $eType)
{

    if(!(strcmp($eType[1], 'PERSON')))
    {
         echo "Word ".$eType[0]." of Stanford entity type PERSON</br>";                   
    }
}`

Nevermind, I was able to solve it on my own. Basically, I focused on combining words if the previous word was also of the entity type person. This is the code that I came up with

<?php
        ini_set('max_execution_time', 300); //300 seconds = 5 minutes
        require "./php_aho_corasick-master/AhoCorasickPHP-master/AhoCorasick.php";
        require "./php_aho_corasick-master/AhoCorasickPHP-master/TreeNodes.php";
        include_once('AlchemyAPI/alchemyapi.php');
        include_once('TextStatistics/TextStatistics.php');

        require './NER/StanfordNLP/Base.php';
        require './NER/StanfordNLP/Exception.php';
        require './NER/StanfordNLP/Parser.php';
        require './NER/StanfordNLP/StanfordTagger.php';
        require './NER/StanfordNLP/NERTagger.php';
        $text= "Muhammad Ali was a great boxer, Ali's greatest rival was Joe Frazier, The name can also be written as M. Ali and J. Frazier.";
        $pos = new \StanfordNLP\NERTagger(
          'C:/wamp/www/GoogleResultsParserTopK/NER/StanfordNLP/stanford-ner-2013-11-12/classifiers/english.conll.4class.distsim.crf.ser.gz',
          'C:/wamp/www/GoogleResultsParserTopK/NER/StanfordNLP/stanford-ner-2013-11-12/stanford-ner.jar'
        );            
        $a="Answer not found";
        //$pos->setJavaPath('C:/Program Files/Java/jdk1.7.0_45/bin');
        $result = $pos->tag(explode(' ', " $text")); 

        var_dump($result);


        $previousValue="";
        $previousType="";
        $FullName="";
        $i=0;
        foreach ($result as $eType) {

            echo $i." ".$FullName."</br>";
            $i++;
            if(!(strcmp($eType[1], 'PERSON')))
            {
                if(!(strcmp($previousType, 'PERSON')) && !(strcmp($FullName, "")))
                {
                    $FullName=$previousValue." ".$eType[0];
                }
                else if(!(strcmp($previousType, 'PERSON')) && (strcmp($FullName, "")))
                {
                    $FullName=$FullName." ".$eType[0];
                }
                else if(!(strcmp($a, "Answer not found")) && !(strcmp($FullName, "")))
                    $FullName=$eType[0];
                else if((strcmp($FullName, "")))
                    $FullName=$FullName." or ".$eType[0];


            }

            $previousValue=$eType[0];
            $previousType=$eType[1];
        }           
        echo $FullName;
