A tutorial on leveraging knowledge graphs for web search

Abstract

Knowledge Graphs are large repositories of structured information about entities like persons, locations, and organizations and their relations. Modern Web search engines leverage such background Knowledge Graphs to create rich search engine result pages for entity-centric search queries. In this document we provide an introduction to Knowledge Graphs and their application to search-related problems. We present techniques to search for entities instead of documents as answer to a search query. Finally we present human computation techniques to build hybrid human-machine systems to solve entity-oriented search tasks making use of Knowledge Graphs.
