Google unveils Knowledge Graph search

Published on .

Mountain View, Calif.—Google Inc. is changing its core search engine to display more intuitive query results based on natural language and crowd-sourcing, including related information in a right-hand sidebar. Called Knowledge Graph, the new technology goes beyond traditional keyword matching by adding to search questions connections between people and things, and offering related information in an adjacent box to help clarify or augment the request. According to Google, search queries now will be informed by such public sources as the CIA World Factbook, Freebase and Wikipedia, as well as more than 3.5 billion data points about relationships between different objects. In January, Google added related content from its Google+ social networking site to search queries. And in April the company tweaked its search algorithm to better filter out low-quality search query results that it calls “webspam.”
