Change how article’s title appear when post shared in Facebook

Hi,

I wish to share my website’s articles on facebook and the problem is that the posts which are generated on it have the following structure : name of the website + name of the article.

That would be more readable if there was only the title of the article. How could I fix this ?
Thx
