Hello! I am Shubham.
I am a Research Associate working with Dr. Jeff Dalton in the Glasgow Representation and Information Learning (GRILL) Lab,
a leading research group in the School of Computing Science at the University of Glasgow that works
on Conversational Information Retrieval. I am part of the
Information, Data and Analysis Section
and world-leading Information Retrieval group.
My research is in Information Retrieval, with an emphasis on Neural Entity-Oriented
Information Retrieval and Extraction.
The goal of my research is to develop novel algorithms that integrate information from text
and entities present in the text to help search engines understand the meaning of the text
more precisely. To this end, I heavily use tools and techniques from Natural Language
Processing and Machine Learning, especially Deep Learning, in my work. The larger goal of
my work is to assist in the design
of intelligent search systems which would one day respond to a user's open-ended and complex
information needs with a complete answer instead of a ranked list of results, thus
transforming the "search" engine into an "answering" engine.
Prior to this, I worked as a Postdoctoral Research fellow with Dr. Laura Dietz
at the University of New Hampshire, Durham, USA . This was also where I completed my PhD working
with Dr. Dietz.
Research Interests: Entity-Oriented Search, Text Understanding, Neural IR, Conversational IR, Knowledge Graphs for IR, Representation Learning for IR.
