I don't know what the Wikipedia schema looks like firsthand but I strongly suspect a disambiguation or category page is nothing more than a page whose content is oriented towards listing other pages. There's no need for it to be a special case; databases store information, they don't care about meaning.
Sorry I meant like
*Java (programming language), an object-oriented high-level programming language
*Java (software platform), software and specifications developed by Sun, acquired by Oracle
*Java virtual machine, an abstract computing machine enabling a computer to run a Java program
they could categorize them like computing ,entertainment ........
below is the link of schema
Yeah, I got what you meant. There isn't a category table in the schema you posted. What makes a category page a category is its content. It's just a special case of a regular page.
But above version shows realtionships
below one is the latest it doesn't show the relationships between entities
but here i could find category table :( . It's confusing me
