Research at Stanford AI Lab, Project: Inference Web (IW): Explanations for the Semantic Web [Oct'04-Jun'05/Oct'05-Mar'06]
- [IW Browser]
During my graduate education at Stanford, I also worked as a Research Assistant at the Artificial Intelligence Lab in the CS department on the Inference Web (IW) project. I was primarily tasked with the ownership of IW Browser, an integrated environment to support effective browsing of IW proofs that explain Semantic Web reasoning tasks.
Specific contributions I made to IW Browser include:
- Adding support for multiple proof rendering strategies, proof styles, and sentence formats
- Integrating the IW Browser to seamlessly plug-in and operate within the IW "container" environment called the IW Toolkit
- Studying the design/implementation of an open-source graphical rendering tool called Touchgraph Wikibrowser and adapting it to the needs of IW
- Extending the IW Browser to leverage Touchgraph capabilities
- Designing an architecture for supporting the translation of KIF sentences to Natural Language for use in the IW Browser, and implementing a solution for the existing collection of IW Proofs in a case-based, iterative manner.
- [Leveraging IW for building a Trust Layer for Wikipedia, published at WWW'06]
I collaborated with other members of the AI Lab to investigate the applicability of Proof Markup Language (PML) and Inference Web for building Trust Layer Solutions, in the specific context of aggregated knowledge repositories where provenance may potentially span multiple sources. The project sought to illustrate the effectiveness of the Inference Web approach by employing it in the context of building a Trust Layer for Wikipedia, as a case study.
My specific contributions include:
- Active involvement in shaping the definition of our approach towards Trust, particularly during brainstorming sessions
- Designing a robust/extensible Solution Architecture for the Wikipedia Trust Layer
- Assuming ownership of ensuring overall consistency of our approach from an architectural standpoint.
- [Derived Rules in IW, published at the Flairs-20 conference, 2007]
Raw proofs in Inference Web are inherently unwieldy, use "primitive" inference rules, and contain detail at a fine level of granularity. Derived Rules are a mechanism that can be used for achieving a proof transformation of IW proofs. Derived Rules work by abstracting away details that preclude easy comprehension of the proof, and hence enable better understanding.
My specific tasks included:
- Consolidation of the existing support and tools available within the IW infrastructure for Derived Rules
- Adding suitable extensions wherever perceived necessary
- Creating a unified environment that supports the effective creation, management, and use of Derived Rules in IW.
Research at Network Systems Lab (NSL), IIT Madras [May'02-Sep'04]
After completing my B.Tech in CS at IIT Madras (May '02), I spent over two years at NSL, pursuing research under the guidance of Dr. S.V.Raghavan. In this period I published three papers in accredited international conferences:
- Formal Description of Perfect Security [ICCC 2002]: This paper seeks to describe security from a theoretical perspective. It provides a formal framework for analyzing the security of a standalone system and extends the formalism to a network of systems.
- DEVISE [IEEE WETICE 2003]: This paper presents DEVISE, a methodology for building Web Services based infrastructures for collaborative enterprises, comprising applications designed as a collection of Web Services and a Computer-Human Interface.
- Sensors On Sea (SOS) [ICISIP 2004]: This paper investigates the applicability of wireless sensors to ocean related disaster management, and proposes a system called Sensors On Sea (SOS) for this purpose. A detailed design and quantitative evaluation of the system are also included.
