Description
LinkedIn is an American business and employment-oriented online service that operates via websites and mobile apps. Launched on May 5, 2003, it is mainly used for professional networking, including employers posting jobs and job seekers posting their CVs. As of 2015, most of the company's revenue came from selling access to information about its members to recruiters and sales professionals. Since December 2016, it has been a wholly owned subsidiary of Microsoft. As of May 2020, LinkedIn had 706 million registered members in 150 countries.
LinkedIn allows members (both workers and employers) to create profiles and "connections" to each other in an online social network which may represent real-world professional relationships. Members can invite anyone (whether an existing member or not) to become a "connection".
Science
Massive amounts of data from LinkedIn allow scientists and machine learning researchers to extract insights and build product features. For example, this data can help to shape patterns of deception in resumes.
