We discuss how\u0026nbsp;\u003Cbr \/\u003Ethe interplay between positive and negative relationships affects the\u0026nbsp;overall functioning of on-line social networks, and we connect our\u0026nbsp;analysis to theories of signed networks from social psychology.\u003C\/p\u003E\u003Cp\u003E In\u0026nbsp;addition to providing a perspective for reasoning about the underlying\u0026nbsp;networks and applications, this analysis provides one of the first\u0026nbsp;large-scale evaluations of these theories using on-line datasets. We\u0026nbsp;find that classical theories capture certain of the underlying effects,\u0026nbsp;but that they are also at odds with some of the fundamental phenomena we\u0026nbsp;observe--particularly related to the evolving, directed nature of the\u0026nbsp;networks.\u003Cbr \/\u003E\u003Cbr \/\u003E\u003Cem\u003ESpeaker Bio:\u003C\/em\u003E\u003Cbr \/\u003EJon Kleinberg is on the faculty of the Computer Science Department at\u0026nbsp;Cornell University, where he holds the position of Tisch University\u0026nbsp;Professor. \u003C\/p\u003E\u003Cp\u003EHis research focuses on issues at the interface of networks\u0026nbsp;and information, with an emphasis on the social and information networks\u0026nbsp;that underpin the Web and other on-line media. \u003C\/p\u003E\u003Cp\u003EHe is a member of the\u0026nbsp;National Academy of Engineering and the American Academy of Arts and\u0026nbsp;Sciences, and serves on the Computer and Information Science and\u0026nbsp;Engineering (CISE) Advisory Committee of the National Science\u0026nbsp;Foundation, and the Computer Science and Telecommunications Board (CSTB)\u0026nbsp;of the National Research Council. \u003C\/p\u003E\u003Cp\u003EHe is the recipient of MacArthur,\u0026nbsp;Packard, and Sloan Foundation Fellowships, as well as the Nevanlinna\u0026nbsp;Prize, Katayanagi Prize, ACM-Infosys Foundation Award, and National\u0026nbsp;Academy of Sciences Award for Initiatives in Research.\u003C\/p\u003E\u003Cp\u003E\u003Cbr \/\u003E*** The Web Science Lecture Series is supported by Yahoo! ***\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EJon Kleinberg of Cornell University\u0026nbsp;discusses how\u0026nbsp;the interplay between positive and negative relationships affects the\u0026nbsp;overall functioning of on-line social networks.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"\u0022Positive and Negative Relationships in On-Line Social Networks\u0022"}],"uid":"27310","created_gmt":"2010-02-25 15:35:22","changed_gmt":"2016-10-08 01:50:53","author":"David Terraso","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2010-04-08T12:00:00-04:00","event_time_end":"2010-04-08T13:30:00-04:00","event_time_end_last":"2010-04-08T13:30:00-04:00","gmt_time_start":"2010-04-08 16:00:00","gmt_time_end":"2010-04-08 17:30:00","gmt_time_end_last":"2010-04-08 17:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1217","name":"Digital Lounge - Digital Life"},{"id":"1220","name":"Digital Lounge"},{"id":"47223","name":"College of Computing"},{"id":"50875","name":"School of Computer Science"},{"id":"50876","name":"School of Interactive Computing"}],"categories":[],"keywords":[{"id":"8863","name":"kleinberg"},{"id":"167295","name":"social"},{"id":"167296","name":"social networking"},{"id":"5449","name":"Web Science"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EFor more information, contact \u003Ca href=\u0022mailto:asb@cc.gatech.edu\u0022\u003EAmy Bruckman\u003C\/a\u003E or \u003Ca href=\u0022mailto:mihail@cc.gatech.edu\u0022\u003EMilena Mihail\u003C\/a\u003E.\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
