Current Research: Evolutionary Behavior of Textual Semantics (EBOTS)

Primary research area:

• Semantic Information Evolution.
  
  
  • Information retrieval,
  • Information clustering and data mining aspects,
  • Semantic web,
  • Ontologies,

• Non-monotonic reasoning
• Cognitive Situation Assessment
  

PROJECTS

• "Deception detection based on actions using non-monotonic reasoning". The project deals with non-monotonic reasoning or as we can call it, "intuitive thinking" for solving a mystery. [paper1 - presentation - Smodels program] [paper2]
  
  
• As a part of learning concepts of advanced multimedia and graphics, I worked on various projects. These include
  
  
  • "Finding top three jokes of live Jay Leno show recording based on measured laughter" using Matlab - “[download entire zip]
  • "Models to detect vertical, horizontal and oblique edges in any given image using Sobel filters" using Matlab - “[download entire zip]
  • "Finding image similarity based on histogram analysis" link
  • "To be able to detect scene changes in a given video avi file"
  • "Semantic Analysis for Video Contents Extraction - Spotting by Association in News Video" by NAKAMURA and KANADE [paper] [presentation]
    
    
• I did a small project to develop a broadcast server and client to simulate client server technology and environment.[Download broadcast client-server zip] [Download RPC client-server zip file]
  
• Me and Josh presented a paper titled "Search Algorithms in intelligent agents" [paper] [presentation]
  
• We did a project to simulate a road trip with a walk bias, lights and moving objects 3D overview. OpenGL was used along with java.
  
  
• I worked on a project wekametal which works with data mining software weak in order to boost classifier accuracy and can compare various results for the given dataset. [presentation]
  
  
• Our Software Engineering Team developed a prototype course management system based on portal concept using jetspeed. This system allows student to see the courses created by their professors. Professors can design their website in small modules of portlets and control what is seen by their students and what is not.
  
  
• I am basically a java programmer and have done quiet good amount of programming on professional level. I initiated a Servlet and JSP container project under name "Splash" (14MB) and took charge of requirements, specification, design, documentation as well as implementation in Java. Currently it is almost compliant with Servlet 2.3 and JSP 1.1 standards by Sun Microsystems. The outstanding feature of Splash is that it enables Servlet and JSP debugging for a developer as it can be run in debug or actual mode. Also it enables administration of container server. It can plug in any open source JSP compiler like Jasper or Oracle JSP engine or GNU JSP. Though I cannot claim Splash to be the fastest and best open source free Java Servlet JSP environment, it surely has performance results near to Tomcat for smaller web archives [ WAR files]. It is XML enabled and can hot-deploy WAR files. Code is provided "as is" under GPL.
