Knowledge Base Completion via Search-Based Question Answering

Source: Research at Google

From Abstract:

Over the past few years, massive amounts of world knowledge have been accumulated in publicly available knowledge bases, such as Freebase, NELL, and YAGO. Yet despite their seemingly huge size, these knowledge bases are greatly incomplete. For example, over 70% of people included in Freebase have no known place of birth, and 99% have no known ethnicity. In this paper, we propose a way to leverage existing Web-search–based question-answering technology to fill in the gaps in knowledge bases in a targeted way. In particular, for each entity attribute, we learn the best set of queries to ask, such that the answer snippets returned by the search engine are most likely to contain the correct value for that attribute.

    Companies know that compromising privacy is bad for business, which is why Microsoft is challenging official disclosure demands in the United States courts. Meanwhile a United States congressional thinktank has concerns about the protection of personal financial records, and a British survey shows just how much customers will punish companies that play fast and loose with their data. But has the pendulum now swung too far in the privacy direction? One survey suggests that the protectionist barriers against digital trade could cause a measurable contraction in gross domestic product - but governments know that privacy wins votes.
