specification properties to derive logical consequences, i.e., facts that are linked by
semantics, but not are present in an ontology.
An OWL makes use of constructors present in the description logic, which is
equivalent to a logic-based knowledge representation formalism. It having been the
remnant of semantic networks, being a collection of thousands of documents and
definitions [5].
Folksonomy is a way of indexing information, having as its main feature the
creation of tags based on the language of the people who use it. It is a relational
way of categorizing and classifying information available on the Web, whether it is
represented through texts, images, audio, video or any other format, its purpose is to
sort out the chaos on the web.
OWL is a language that defines and instantiates Web ontologies, it can formalize
a domain, define individuals and statements about them, define classes and properties
of these classes, and using formal semantics. OWL has the ability to specify how to
derive facts that are not present in the ontology, but are bound by semantics, it is the
most widely used language of ontology developed [5].
OWL has better facilities for expressing semantics and meanings than XML, RDF,
and RDF Schema, although it is based on RDF and RDF Schema and uses XML
syntax. It is designed for applications that need to process information rather than
just presenting it to humans, is designed for use by applications that need to process
information content, rather than just displaying that information [51].
4.1.1 Lite, DL, and Full
OWL is divided into three sub-languages, OWL Lite, which supports users who need
a simple classification hierarchy and constraints, using only a few features of the OWL
language, and has more limitations than OWL-DL or OWL-Full. OWL-DL corresponds to description logics, which is a research area that studies a particular fragment
of first-order logic that supports users who need maximum language expressiveness
without losing computational fullness and decidability language reasoning. Is used
by users who want maximum decidability, concerning all computations will end in a
computational finite time just as expressivity, with completeness, which all conclusions are guaranteed to be computable. It includes all OWL language constructs
but may be used under certain restrictions concerning the use of RDF and requires
disjunction of classes, properties, individuals, and data values [52].
OWL-Full supports users who need maximum language expressiveness, with
greater syntactic freedom but no computational guarantees, used by users who want
maximum RDF expressiveness and syntax independence. Full and DL versions
support the same set of OWL language constructs, although with different constraints.
The Full version allows OWL and RDF Schema to be mixed without requiring the
disjunction of properties, individuals, classes, and data values, i.e., a class can be
both class and individual at the same time [5, 52, 53].
