Introduction to: Triplestores Juan Sequeda.
From the post:
Triplestores are Database Management Systems (DBMS) for data modeled using RDF. Unlike Relational Database Management Systems (RDBMS), which store data in relations (or tables) and are queried using SQL, triplestores store RDF triples and are queried using SPARQL.
A key feature of many triplestores is the ability to do inference. It is important to note that a DBMS typically offers the capacity to deal with concurrency, security, logging, recovery, and updates, in addition to loading and storing data. Not all Triplestores offer all these capabilities (yet).
Unless you have been under a rock or in another dimension, triplestores are not news.
This is a short list of some of the more popular ones and illustrates one of the problems with “inferencing,” inside or outside of a triple store.
The inference in this article says that “full professors,” “assistant professors,” and “teachers” are all “professors.”
Suggest you drop by the local university to see if “full professors” think of instructors or “adjunct professors” as “professors.”
BTW, the “inferencing” is “correct” as far as the OWL ontology in the article goes. But that’s part of the problem.
Being “correct” in OWL may or may not have any relationship to the world as you experience it.
My wife reminded me at lunch that piano players in whore houses around the turn of the 19th century were also called “professor.”
Another inference not accounted for.
