Knowledge Graph (Google)The Knowledge Graph is a knowledge base from which Google serves relevant information in an infobox beside its search results. This allows the user to see the answer in a glance, as an instant answer. The data is generated automatically from a variety of sources, covering places, people, businesses, and more.
Knowledge baseIn computer science, a knowledge base (KB) is a set of sentences, each sentence given in a knowledge representation language, with interfaces to tell new sentences and to ask questions about what is known, where either of these interfaces might use inference. It is a technology used to store complex structured data used by a computer system. The initial use of the term was in connection with expert systems, which were the first knowledge-based systems.
MetawebMetaweb Technologies, Inc. was a San Francisco–based company that developed Freebase, described as an "open, shared database of the world's knowledge". The company was co-founded by Danny Hillis, Veda Hlubinka-Cook and John Giannandrea in 2005. Metaweb was acquired by Google in 2010. Google shut down Freebase in 2016, transferring some of the data that met the required notability criteria to Wikidata. FundingOn March 14, 2006, Metaweb received $15 million in funding.
DatabaseIn computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system.
