Ontology Learning Techniques

admin — Wed, 04 Feb 2009 14:26:15 +0000

As I planned, finalizing my (quick) studies on ontology learning techniques. Ontologies play a key role in semantic web and technologies by defining concepts and relations between these concepts. Thus, there are significant studies on this subject and some useful techniques discussed in ontology learning:

Ontology learning from texts
Ontology learning from dictionary
Ontology learning from knowledge base
Ontology learning from semi-structured schemata
Ontology learning from relational schemata

Almost all of the techniques above require a good knowledge and infrastructure of NLP (Natural Language Processing) to obtain effective results. I though ontology learning from dictionary would be easy compared to other methods for Turkish language. However, it requires WordNet like dictionaries that what I don’t have. Sabancı University NLP group works on BalkanNet but I don’t think it is ready to use.

Also, I’m searching about ontology-based system designs and implementations.

Trends in Ontology-Based Systems

When I first see the book “Semantic Web Technologies: Trends and research in ontology-based systems (Hardcover)” hadn’t enough time to go on the previous week. This, morning I couldn’t sleep and so had some free time to search http://ieeexplore.ieee.org/. The query “Ontology-Based” in titles hit 100 papers and most of them are published in 2008 or 2007. I’ve got printed copies of studies from various versions of ontology based systems like “Ontology-Based Knowledge Management”,” Ontology-based Information Integration in Virtual Learning Environment”, ”An Ontology-based Approach to Text Summarization” … etc.

My adviser already has a proposal on multimedia related systems and suggests me to consider it. I may combine those studies with ontology based infrastructure and come up with new subjects. But still an idea …

I’m listed in Semantic Web Twitter Pack as Semantic Web people to follow in twitter. Thanks to @CleverClogs

My Red Alert 3 Strategies

After, Red Alert 2 I’m getting familiar with Red Alert 3 (RA3) and enjoying the game when I win Japanese forces. My favorite nation in the game is Russians. Yes, I like to hear the sound “Kirov Reporting!”. My main strategy in the game is;

Barracks
Train soldiers (mixed)
Power Planet
2 Ore Mines
War Factory
Super Reactor

I always follow my opponent’s movements and decide how to strike. It may air, ground or super weapon attack.

I’m not just playing games but reading papers on machine learning techniques which are used in ontology learning for semantic web. Also, I’m preparing a schedule for 2009 conferences and our plan is to have something valuable till April so, we can submit it this year’s events.

Ontology Learning

I blogged before about semantic web research topics which I’ve been interested in. While I have a little free time I planned to focus on ontology learning. I know it is a big issue and cannot be handled in a tiny time span. However, at least, I can write a review on ontology learning techniques such as machine learning and machine language translation techniques that would be useful to decide to go on this subject.

I’m still trying to make a decision to apply this internship or not.
