I'm Kevin Dela Rosa an alumnus Carnegie Mellon's Language Technology Institute. In addition to my masters degree in language technology, I have a bachelors degree in Software Engineering & Physics from the University of Texas at Arlington. In the past I worked at ARRI, NIST, and SPAWAR, and collaborated with NASA MSFC folks.

My academic interests include applied machine learning, question answering, information retrieval, multimedia analysis / retrieval (music & video), and social media. Outside of work I'm interested in astrophysics, astrobiology, web development, music recording, comics, science fiction, and stand-up comedy.

After graduating from the LTI I started working for Amazon.com. Visit my official website, http://kevindelarosa.com, for more up to date information on myself. Also, if you are an LTI student interested in opportunities at amazon, feel free to drop me a line

Select Course Projects

Open Advancement of Question Answering, Spring 2010
Question Answering, Carnegie Mellon
- Collaborated with other students in a lab course to build a basic question answering system from scratch that answers factoid questions from TREC data sets. Focused on software architecture changes and answer selection algorithms.

Programmable Network Simulator, Fall 2008 to Spring 2009
Senior Design, University of Texas at Arlington
