Owl Presentation

  1. 1. Simon Azzopardi 08084871 SUPERVISOR: Arantza Aldea
  2. 2. • Interactive Social networking Site amongst users and businesses. • A program that could profile and cluster customers in order to determine their buying behaviour. • A program that turns data into usable knowledge.
  3. 3.  Social Networking website that would understand user’s tastes; meaning:  A website which has interactivity that allows businesses to derive Intelligence through such user interaction  This is done by:  Using Ontology to define profiles.  Results in:  having a system that is updateable and can be continuously perfected.  Having a background in wines, grouping people with similar tastes was the objective.
  4. 4.  It is HUGE  200,000,000 Blogs exist  73% of internet users have read a blog.  It is TRUSTED  78% of people trust the recommendations of others  14% of people trust advertising  It mould PERCEPTION  32% trust blogger’s opinion on products and services  SOCIAL NETWORKING IS NOT GOING AWAY!
  5. 5. A website had to be created that would interact with users. This needed to involve the following features:  Login Accessibility  Creating accounts  Allowing users to submit Articles/Comments*  A database for sorting users and articles.*  XAMPP was used to interact between php and MySQL
  6. 6.  an ontology describes a formal specification of a certain domain:  Shared understanding of a domain of interest  Defines objects and their relationships  Use of Triples in the form of subject, predicate, object. “… a specification of a conceptualisation" [Gruber, T.  1993]  Protégé facilitates OWL creation and manipulation by creating an Ontology that is  a formal representation of a domain  machine manipulability of the model  All done through a graphic user interface
  7. 7. •Define classes and their hierarchy •Define relationships between the classes •Define properties of the classes •Define Individuals of such classes •Define any rdfs: label of such individuals
  8. 8.  An Ontology defines a concept.  Due to the subject matter at hand (consumer preferences), the Ontology had to define various tastes and properties of wines rather than physical properties.
  9. 9.  Jena is an API that allows programmers to manipulate an ontology.  Jena incorporates SPARQL that allows the Java program to Query the Ontology and retrieve information
  10. 10.  The site has login functionality and one can create an account.  Database is set up and interacting with php and Java  A Java program queries a defined Ontology to retrieve the various preferences using SPARQL  Using MySQL, the results are manipulated into keywords and are queried against the articles to retrieve a count per article and per user  The Database is updated by listing user preferences  User preferences are grouped by username to achieve clusters  The ontology can be updated at any time, with no effect on the Java program, as long as the super classes remain.
  11. 11.  Michael Had the below Ar ticle:  A great debate raging in the wine world today is over the dif ferences between wines coming from the New World versus the Old World. Much of this arguing quickly becomes obscured by emotions. Wine has the ability to create great passions. This, in some way, is proof of its greatness and impor tance to humankind. There are two philosophies when it comes to Old World vs. New World wines. The first and mostly known way of thinking is that Old World wines come from the "classic wine making regions" in Europe. New world wines come from ever ywhere else. The Old World can generally date their origins of wine production back to the Roman Empire and beyond. Naturally the growers from these regions-France, Germany, Austria, Italy and Spain have some pride in this histor y. Many growers are descendants from families that have been tilling the soil for generations. New World wines come from Latin America, Australia, America, South Africa and New Zealand. Faced with an unbridgeable time gap these growers have had to develop new technologies to insure the quality of what they grow. Whatever the methods used many New World countries have managed to come up with a lot of good wine. In the case of Chile, Australia and South Africa this wine is of ten of ver y good value. The Southern Hemisphere growers are helped by a climate that changes little so there are fewer vintage variations. The second philosophy concentrates on style rather than geography. Old World wine refers to ear thy, musty wines where as New World wines are fresher and fruitier. This philosophy states that Old World wines have subtle fruit, are ear thy, elegant and light to medium bodied. New World wines are ver y fruity and clean with lots of oak and high amounts of alcohol. At first glance, one would disagree with this philosophy as a Recioto della Valpolicella is a rich wine that is high in alcohol and oak and is ver y Old World. The second Philosophy is based upon the understanding that New World and Old World wine producing regions is slowly closing the gap. With typical Bordeaux blends coming from South Africa and Sangiovese grapes growing in California, it is easy to understand that wine opinions and concepts are becoming more complex. Many wine lovers are opinionated and would tend to be bias towards a favourite, the most impor tant aspect is that the Old World does not lose its intrinsic personality and deep relationship with the soil. The Closing of the gap between the two worlds can only benefit the consumer. Diversity is never a bad thing. Many consumers want a reliable wine of great value to eat dinner with and these days they have a whole world to choose from.  Result: “Michael likes New World Wine”  Database is updated with the following row: Michael | New World Wine
  12. 12.  The following still need to be completed:  Allowing user’s to upload article’s  Allowing user’s to comment on articles  Showing the user’s preference on the web page  Thiswill be done by querying the database since all preferences are stored in a unique table.
  13. 13.  Using Ontologies is an effective way of having an Intelligent website.  Being updateable provides for continuous improvement and perfection  OWL already has a lot of tools that could be used (Protégé/Jena/SPARQL/Data Genie…)  A simple social networking website could use user interaction to acquire intelligence, a vital part for any business.
  14. 14.  Increase the use of the Ontology by using properties such as cardinality and restrictions.  Recommend users of similar (clustered) preferences and tastes  Adding more interaction for users to gain further knowledge  Increasing the complexity of the Ontology to include further tastes and patterns to have more defined profiles  Possible future work: Using Data Genie to import all the database into OWL, having table names as classes and rows as individuals.
