Question

I m 为html网页安装一个网络报废器。问题是背景关系,因为我需要决定一线内容与非行内容之间的关系,因此我可以说,这些内容是相关的,还是不是背景观点:

页: 1

$str1 = "president obama visited Barcelona yesterday"; //politics context
$str2 = "Barcelona was defeated from Chelsea yesterday"; //sports context

页: 1

$str3 = "Obama s appearance on Late Night With Jimmy Fallon "; //media context
$str4 = "Late Night show with jimmy fallon"; //mdeia context

第一例

<>strong>$1 and $str2 are大体不同,因此,关系可能为10% 或

第二例

<>strong>$str3 and $str4 are in the same context (media)beit$3 about President obama and the $4 about Ji Fallon but both are related to end road show,So relation may be 90%

I m using the Porter-Stemmer algorithm to remove the common endings from words. What to do next?

Answer 1

The keywords are string metrics, fuzzy matching...

Answer 2

$exstr1=explode(" ", $str1);
$exstr2=explode(" ", $str2);
foreach( $exstr1 as $exitem)
{
     if (in_array($exitem, $exstr2 ) $match++;
      else $mis++;
}
$percent=$match/($match+$mis)*100;
