+ <p>The Stanbol Ontology Manager provides a <strong>controlled
environment</strong> for managing ontologies, <strong>ontology
networks</strong> and user sessions for semantic data modeled after them. It
provides full access to ontologies stored into the Stanbol persistence layer.
Managing an ontology network means that you can activate or deactivate parts of
a complex model from time to time, so that your data can be viewed and
classified under different "logical lenses". This is especially
useful in <a href="reasoners.html">Reasoning</a> operations.</p>
+<h2 id="usage_scenarios">Usage Scenarios</h2>
+<h3 id="user_networks">User networks</h3>
+<p>In your CMS, you might be interested in figuring out the trust and
acquaintance network of its users. This can be a combination of the
<em>asserted</em> network (i.e. what other users are included in the contact or
friend list of a given user) with the <em>inferred</em> network (e.g. exclude
those who are in the contact list of a blacklisted user). The latter can be
derived from the user activities over the user-generated content of your CMS
(e.g. blogs posts, forum posts, reviews, tweets, ratings). </p>
+<p>Both types of networks can be modelled as ontologies. Models can be build
on the <em>class</em> level, or <em>TBox</em> (e.g. everyone who is an
Administrator is also a User, and collaborates with every other Administrator
of the same system) and on the <em>instance</em> level, or <em>ABox</em> (e.g.
John is a friend of Mary, who created blog post bp345263 on 3/10/2012 at
15:10). These models can all be stored using the Store facility of the Ontology
Manager.</p>
+<p>Using a <a href="reasoners.html">reasoner</a> you can classify all the
knowledge loaded on Stanbol, but this can be a time-consuming process due to
classifying knowledge we are not interested in for this task. <a
href="ontologymanager/ontonet.html">OntoNet</a> allows you to select only the
"interesting" parts of your knowledge base. For example, if the
knowledge contains classifications of animal species, you may want to
deactivate that model when reasoning on user networks. Likewise, you may want
to consider the user profiles <em>today</em>, rather than who was a user's
friend five years ago. Therefore, on the instance level you will exclude the
profile history and only consider today's snapshot.</p>

+<p>A Web <strong>Ontology</strong> in computer and information science is a
shareable conceptual model of a part of the world <a href="#ref1">[1]</a>. This
model describes concepts terms of their characteristics and their relations
with other concepts.</p>

<ul>
<li><a href="ontologymanager/ontonet.html">OntoNet</a> - allows to
construct subsets of the knowledge base managed by Stanbol into OWL/OWL2
ontology networks</li>
<li><a href="ontologymanager/registry.html">Registry</a> - manages ontology
libraries for bootstrapping the network using both external and internal
ontologies</li>
<li>Store - create, read, update and delete operations on single
ontologies stored in Stanbol. These operations can be performed on entities,
axioms, and whole ontologies.</li>
