Pinterest is a relatively new and extremely popular content-based social network. Building on a body of work showing that the hidden network whose edges are actual interactions between users is more informative about social relationships that the follower-following network, we study the activity graph composed of links formed by liking, commenting, and repinning, and show that it is very different from the follow network. We collect data about 14 million pins, 7 million repins, 1.6 million likes, and several hundred thousand us","authors_text":"Ajita John, Bluma Gelley","cross_cats":["physics.soc-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SI","submitted_at":"2014-05-07T20:58:26Z","title":"Like, Comment, Repin: User Interaction on Pinterest"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1405.1752","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:e3befd98f3ef285a28664b3c25dcfe405b60825abc870285589adb8e8a114021","target":"record","created_at":"2026-05-18T02:52:22Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"ec039504dd7bb0699cbff401de419010aa8cfb309a0553cabc54d81ccf4218a0","cross_cats_sorted":["physics.soc-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SI","submitted_at":"2014-05-07T20:58:26Z","title_canon_sha256":"45b7f1ac3e371cfdd667ea645ae0ce69eec5f51d91b22ae57b355ba76d0ba2fe"},"schema_version":"1.0","source":{"id":"1405.1752","kind":"arxiv","version":1}},"canonical_sha256":"560c77973fc078c930833ec44a583cba39e2f32710f759907a7db27fe1bb2dd5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"560c77973fc078c930833ec44a583cba39e2f32710f759907a7db27fe1bb2dd5","first_computed_at":"2026-05-18T02:52:22.686700Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:52:22.686700Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"MUy8llnqYtAzge4JKODKwLbTpA4al/CKvPj9jJ77TrDQMuz/K4Ha9CmkIRhtthpVrhXOBUNluIXQXBGlviFJCA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:52:22.687406Z","signed_message":"canonical_sha256_bytes"},"source_id":"1405.1752","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e3befd98f3ef285a28664b3c25dcfe405b60825abc870285589adb8e8a114021","sha256:f34632fa74e1920d834a5307a70eb998d61497c7fdae873b65d19b2504a907e8"],"state_sha256":"5156872513f952111b73d1ae1e2c3066ae6f956aad517104eb1f037f904308c3"}
