--- abstract: "Access to global information is of primary importance in a\r\nglobal world. The Internet contains a huge amount of documents and it has a big potential as a news media, but the key is in the mechanism in which information is accessed. This paper describes a novel idea consisting\r\nin combining the potential of both social networks and search engines. The project is still at its preliminary stages and this paper has to be intended as work in progress. We describe here the basic ideas\r\nbehind a trust ranking algorithm based on the activities and networking performed by users on a social network. We motivate the need for Polidoxa, the combined social network and search engine, and we finally describe the advantages over traditional media, traditional search engine\r\nlike Google and social network such as Facebook." accompaniment: [] book_title: ~ commentary: ~ completion_time: ~ composition_type: ~ conductors_id: [] conductors_name: [] contact_email: ~ copyright_holders: [] corp_creators: [] creators_id: - manuel.mazzara@newcastle.ac.uk - antonio.marraffa@polidoxa.com - luca.biselli@mac.com - luca.chiarabini@unipr.it creators_name: - family: Mazzara given: Manuel honourific: '' lineage: '' - family: Marraffa given: Antonio honourific: '' lineage: '' - family: 'Biselli ' given: Luca honourific: '' lineage: '' - family: Chiarabini given: Luca honourific: '' lineage: '' data_type: ~ date: 2011 date_type: published datestamp: 2011-06-13 17:18:53 department: ~ dir: disk0/00/00/03/11 divisions: [] edit_lock_since: ~ edit_lock_until: 0 edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 311 event_dates: ~ event_location: ~ event_title: INTRUSO 2011 event_type: workshop exhibitors_id: [] exhibitors_name: [] fileinfo: /style/images/fileicons/application_pdf.png;/311/1/Polidoxa.pdf full_text_status: public funders: [] id_number: ~ importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: ~ lastmod: 2011-06-13 17:18:53 latitude: ~ learning_level: ~ longitude: ~ lyricists_id: [] lyricists_name: [] metadata_visibility: show monograph_type: ~ note: ~ num_pieces: ~ number: ~ official_url: ~ output_media: ~ pagerange: ~ pages: ~ patent_applicant: ~ pedagogic_type: ~ place_of_pub: ~ pres_type: paper producers_id: [] producers_name: [] projects: [] publication: ~ publisher: ~ refereed: TRUE referencetext: ~ related_url_type: [] related_url_url: [] relation_type: [] relation_uri: [] rev_number: 19 series: ~ skill_areas: [] source: ~ status_changed: 2011-06-13 17:18:53 subjects: - deploy_method_other succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ task_purpose: ~ thesis_type: ~ title: 'Polidoxa: a Sinergic Approach of a Social Network and a Search Engine to Offer Trustworthy News' type: conference_item userid: 217 volume: ~
