There are classifying and clustering tools that help you along, but don’t produce ontologies. They essentially filter the noise, much like free text search engines filter and then rank documents according to some relevance ranking algorithm. That is, they can produce candidates based on text analysis, and those candidates are mostly node-based, i.e., names of potential categories: classes mainly; properties: maybe but these are harder; relations: not much either. These technologies are term-based, i.e., based mostly on statistical NLP and text analysis. Both ontology learning and ontology induction from text are very primitive, as of now. Their results can be input into an ontology-adjudication phase, but are just early tools. If you want axiomatic ontologies, forget it.

Subject: Re: [ontology-summit] An example of the worth of ontology development
There are lots and lots of tools and products that do this. I am not familiar with them myself. Google "ontology learning".

In general, it is any enterprise or market wherein He Who Learns Fastest Wins. Specific examples are Military Intelligence, Business Intelligence, Conference Management (evolving to social network interlocutor), Learning Management (as modern education of youth is finally freed from government intervention), and Autonomous System engagement management. Personalized, Molecular-level medicine may become the Killer App.
