Abstract: Subjective data refers to data that contains opinions and experiences. Such data is ubiquitous in product reviews, tweets, and discussion forums in social media. Consumers today spend considerable time sifting through subjective data to make informed decisions about purchases. At Megagon Labs, we are building technologies to synthesize knowledge from subjective data and to facilitate searching over them. In this talk, I will describe how consumers can enjoy an enhanced search experience through a system that directly supports both subjective and objective search; by harnessing information "outside the box", in the text of online reviews or social media, managing the extractions as first-class citizens in a data management system, and answering subjective queries.
