The great idea of semantic web, as conceived in the early beginnings, was mostly visionary and rather impossible to build. This doesn't mean the that whole concept has failed. It advanced many fields of AI and created many initiatives which are quite vibrant to this day (e.g. Linked Data). The illusion of failure of the semantic web is mostly due to the fact that today there are less semantic web projects funded. The money goes to other things that are now on the rise, the same as it was with semantic web 10 years ago. However semantic web is still here, with many tools mature enough to be applied in the industry. I don't expect it to dissapear completely.
