Startup - Opinion8

  • CEO & Co-founder at Opinion8 (2014 Oct ~ )
  • Don’t get results – get opinionated.
    Opinion8 presents PopOp, a new way to search. Not just for information, but for opinions.
    Get consensus. Get answers. And get better advice about everything.

Research

 My research interests in a broad sense focus on understanding the fundamental aspects of building a large-scale information system that can answer complex queries over a large number (billions) of heterogeneous data sources. I focus on tackling the challenge particularly in Web data mining, Opinion mining, Information Retrieval, Entity-based Search Engine.
