We introduce the concept of word storms, a visualization tool for analysing corpora of documents. A word storm is a group of word clouds, in which each cloud represents a single document, juxtaposed to allow the viewer to compare and contrast the documents. We present a novel algorithm that creates a coordinated word storm, in which words that appear in multiple documents are placed in the same location, ","authors_text":"Charles Sutton, Quim Castella","cross_cats":["cs.DL","cs.HC"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2013-01-03T17:02:56Z","title":"Word Storms: Multiples of Word Clouds for Visual Comparison of Documents"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1301.0503","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":"sha256:92fc8490b76f097d7bc5fc0ea762b5648802ae7695fe0ceb566fc0d177ff5a32","target":"record","created_at":"2026-05-18T03:37:19Z","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":"136f2643461325118d72c810531317256bf19b62ad659bcdceb97301d2f0f3b3","cross_cats_sorted":["cs.DL","cs.HC"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2013-01-03T17:02:56Z","title_canon_sha256":"2590c395c22e211bec26d64916c1027f42965cf8a8b805babeb262ca92c1e387"},"schema_version":"1.0","source":{"id":"1301.0503","kind":"arxiv","version":1}},"canonical_sha256":"baf577c2dcd81defc3c21800a9ec4d3b71c0f929b23dde15232dd0c1d3ec6676","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"baf577c2dcd81defc3c21800a9ec4d3b71c0f929b23dde15232dd0c1d3ec6676","first_computed_at":"2026-05-18T03:37:19.470500Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:37:19.470500Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"cIJ1IVxPGesLOOwHOvIMtgJGKJ5hOkHBr+lyEvDQd1DHlAzFjhT7qRTa/T4cbRi6FuMbwLNi7B177V5KbY7wCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:37:19.470947Z","signed_message":"canonical_sha256_bytes"},"source_id":"1301.0503","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:92fc8490b76f097d7bc5fc0ea762b5648802ae7695fe0ceb566fc0d177ff5a32","sha256:cffd8421866f643d3c4f09aea3b94f6f4403382995a1ccbe6669a77f8c9c1a97"],"state_sha256":"6baca43242132bd9d5aef26c89b79db657f9c924900168a80c921889da8988af"}
