ONTOLOGY :3

Assalamualaikum, this may be my last entry for this semester. As for now, I would like to talk about ontology (web semantic). based on the notes/slides by Prof. Do Van Thanh, An ontology is typically a hierarchical data structure containing all the relevant entities and their relationships and rules within that domain. DAML + OIL and OWL is a type of web ontology. DAML+OIL is a language for expressing far more sophisticated
classifications and properties of resources than RDFS and providing facilities for data typing based on the type definitions provided in the W3C XML Schema Definition Language (XSDL) and it allows one to express classifications by inference rather than by explicitly listing which resources go into which
buckets.And for OWL, it is derived from DAML+OIL adds more vocabulary for describing properties and classes: among others, relations between classes (e.g. disjointness), cardinality (e.g. "exactly one"), equality, richer typing of properties, characteristics of properties (e.g. symmetry), and enumerated classes. OWL has three sub languages which is OWL Lite, DL, and Full. OWL Lite provides simple constraints such as providing cardinality of 0 and 1. It also has lower formal complexity than OWL DL. As for DL(description logic), it supports those users who want the maximum expressiveness while retaining computational completeness and decidability. And lastly as for Full, it is meant for users who want maximum
expressiveness and the syntactic freedom of RDF with no computational guarantees.
