I try to find a way to define in PHP a semantic by comparing some phrases and find occurence for example i have something like
Array
(
[0] => Cats love Mouse Car Dog Fish
[1] => Pictures Cats Some Text Mouse
[2] => Game of thrones 2015 Series
[3] => Stark Series lannister John Game of thrones
[4] => Pop Rock David Bowie Music
[5] => David Great Lower Text Bowie
)
And I expected for the output
Array
(
[0] => Cats Mouse
[1] => Game of thrones Series
[2] => David Bowie
)
How can I proceed ?
