wow!! Accepted

huh.. my paper for the IEEE-ICSC 2008 has been accepted. Well we actually sent this paper some where around in the first week of march, and finally got eh results just yesterday. My paper was titled "Optima: Tool for Ontology Alignment with Application to Semantic Reconciliation of Sensor Metadata for publication in SensorMap". Well i mentioned about the tool in the previous post. It was actually accepted in the demo track. I should be going to california to present the demo between 4-7 august 2008. A link to the paper is present in my home page.

Optima- An Ontology Alignment Tool

Wow finally,  i am done with my tool Optima. I have been working on this tool for over an year. Well it did take me a long time and the reason for that is, i have been working on 2 large code bases, and the usual the code is not at all commented and it gave a me a really tough time to get through their code.  

My main idea here is to generate an automated visualized ontology alignment tool, where a user can enter a couple of ontologies to be matched and thus generate a final alignment between the ontologies.  There are no alignment visualization tools so far, that gives a beautiful and easy to use interface, and a powerful underlying algorithm that performs the alignment. The first code base is of the interface and the second one is of the ontology alignment.

The interface is actually a change to the open source ontology visualization tool welkin developed as a part of MIT -simile project. The interface is pretty cool, but the usual the documentation is really bad. 

The second code base is of ontology alignment. This algorithm is developed as a part of the research conducted by my professor Dr.Prashant Doshi. I later enhanced the algorithm to work for larger sets of ontologies (well not so big but usually in the range of about 300-500 nodes per ontology). I enhanced it by providing an ability to partition the ontology automatically internally, to work on smaller sets and the final result that corresponds to the complete ontology is generated. 

I finally integrated both the tools, the visualization tool, the alignment algorithm , to generate the final tool optima, the alignment visualization tool. 

So far just the basic version is released as a webstart and i expect to release the documentation for the tool within week from now.  I finally decided to have my code to be completely documented and commented. I am actually planning to have the tool an open source, and i want the others who are later working on the code to understand it clearly. 

A screen cast for the tool is present at Optima

A demo version of the tool Optima

A few papers are also available at my research home page Optima

(Yes you are right!! i have the same page references in all the 3 cases. i was just trying to increase my home page rank to advertise my tool) 

Thanks guys, any questions will be greatly appreciated.
