<h1 class="title">Using custom/local vocabularies with Apache Stanbol</h1>
- <p>For text enhancement and linking to external sources, the Entityhub
provides you with the possibility to work with local indexes of datasets for
several reasons. Firstly, you do not want to rely on internet connectivity to
these services, secondly you may want to manage local changes to these public
repository and thirdly, you may want to work with local resources only, such as
your LDAP directory or a specific and private enterprise vocabulary of your
domain.</p>

and to use the reasoning components over it.</p>

many organizational use cases such as beeing able to detect various types of

vocabularies. For small vocabularies, with Entithub one can also upload simple
ontologies together instance data directly to the Entityhub and manage them -

installation.</p>

kind of enhancements you want to support. If your enhancements are

concepts from your custom vocabulary, you should work with the
TaxonomyLinkingEngine to both, find occurrences and to link them to custom
entities. In this case, you'll get only results, if there is a match, while in
the case above, you even get entities, where you don't find exact links. This
approach will have its advantages when you need to have a high recall rate on
your custom entities.</p>
