An interest graph is an online representation of the specific things in which an individual is interested.〔rr11. ("How the Interest Graph will shape the future of the web" ), MIT Entrepreneurship Review, Cambridge, 1 April 2011. Retrieved on 11 March 2013.〕 Interest graphs have perceived utility and value because of the premise that people’s interests are a major aspect of who they are, forming part of their personal identity, and can be used as indicators of such things as what they might want to do or buy, where they might want to go, or who they might want to meet, follow or vote for.〔Tullman, Howard A. ("Where Social Media Will Take Us in 2013" ), Inc.com, 28 December 2012. Retrieved on 11 March 2013.〕 ==Relationship of interest graph to social graph== Interest graphs and social graphs are closely related, but they are not the same thing. Interest graphs are used to create people’s interest networks.〔Miller, Paul. ("Radar Networks opens Twine to the world with version 1.0" ), ZDNet, 20 October 2008. Retrieved on 14 March 2013.〕 Where Facebook and other social networks are organized around an individual’s friends, or social graph, interest networks are organized around an individual’s interests, their interest graph.〔Jamison, Jay. ("Three Reasons to Watch Interest-Based Social Networks in 2013" ), All Things D, 28 December 2012. Retrieved on 11 March 2013.〕〔Firuta, Jakub. ("How to create an Interest Graph" ), LiveChat, 12 July 2012. Retrieved on 17 July 2012.〕 Much as social graphs are maps of individuals’ social media connections that follow them across the web, interest graphs as maps of individuals’ interests can likewise follow them across the web. In this way an individual’s interests, as represented in an interest graph, provide a means of further personalizing the web〔Harris, Derrick. ("The personalized web is just an interest graph away", GIGAOM, 15 March 2012. Retrieved on 11 March 2013. )〕 based on intersecting the interest graphs with web content. Interest graphs or interest networks can in some cases be derived from social graphs or social networks and may maintain their context within that social network.〔Hossain, Nadim. ("Why the Interest Graph Is a Marketer’s Best Friend" ), Mashable, 19 June 2012. Retrieved on 17 July 2012.〕 These are specifically social interest graphs or interest-based social graphs.〔Perez, Sarah. ("Formspring Relaunches As An Interest-Based Social Network" ), TechCrunch, 19 June 2012. Retrieved on 11 March 2013.〕〔Jamison, Jay. ("Beyond Facebook: The Rise Of Interest-Based Social Networks" ), TechCrunch, 18 February 2012. Retrieved on 11 March 2013.〕 For an interest graph to be accurate and expressive, it needs to take into account explicitly declared interests, for example "Likes" on Facebook or “Interests” in a LinkedIn profile, as well as implicit interest inferred from user activities such as clicks, comments, () photos and check-ins. Social networks are often a source for this data.〔Rashad, Moataz. ("5 Key Components of a Successful Interest Graph" ). Mashable, 21 February 2012. Retrieved 27 November 2012.〕〔Rogers, David.
