about me
My name is Juan Sequeda and I am a Ph.D. Student in the Department of Computer Sciences
at the University of Texas at Austin. I started my undergrad in computer science at the Escuela de Ingeneria de Sistemas y Computacion at the Universidad del Valle in Cali ,Colombia. I then transfered to the University of Texas at Austin in 2006 and received my B.S. in Computer Sciences in 2008.
My research interest is Semantic Web, Ontologies and Databases and my current research involves integrating databases with the Semantic Web. I am an Invited Expert on the W3C RDB2RDF Working Group. My advisor is Prof. Daniel P. Miranker. I am on the organizing committee of the 1st International Workshop on Consuming Linked Data (COLD2010) co-located at the 9th International Semantic Web Confernece (ISWC2010) in Shanghai, China During the summer of 2009, I worked with Oscar Corcho and Asuncion Gomez-Perez of the Ontology Engineering Group at the Universidad Politecnica de Madrid. | |

Ultrawrap: A Virtual Triple-store for Semantic Web Data Management There is a huge gap between the Semantic Web and Database community. However in recent years, we are starting to see interest from the Database community in the data management aspects of the Semantic Web. The databases to manage Semantic Web data, called triple stores, can be created using relational databases as the backend. However current triple-stores with relational backend have poor performance. The research problem is to identify other ways to take advantage of the existing relational database infrastructure.We have created a novel approach that exposes legacy data in relational databases as a triple-store without the need of replicating the data. Our approach demonstrated that existing commercial SQL query engines already subsume all the algorithms need to support effective query rewriting from the SPARQL language (query language for the Semantic Web) to SQL. Furthermore, our experimental results showed that our approach is better than all other existing triple-stores. Morphster Morphster is an Image-Driven Ontology Editor that supports morphologically based phylogenetic studies. We have developed an innovated method of creating ontologies through images.

Activities
I do a lot of travelling due to academic conferences. Since 2000 arranging a travel and make all pre-arrangements for hotel reservation and things like that has become a lot more easier. You can use the Internet for that purpose by means of specialized internet resources with advise on restaurants, landmarks and other related stuff. Even though I travel a lot, I always return back to Austin, the city where the University is situated; while Cali remains my hometown, which I visit several times a year. |
