Any reason for ontology reuse?

Dear all,

I would like to know, which are the specific reason(s),
for reuse terms from well-known vocabularies in the process of Publish
Linked Data on the Web?
(Thesis, dissertation or paper references are very welcome.)

In [1] we can find one reason.

*"In order to make it as easy as possible for client applications to process
your data,
*
*you should reuse terms from well-known vocabularies wherever possible"*

Any other reason?

Thanks in advance for your help.

Best Regards,

Percy
