We contribute Scideator, the first human-LLM system for facet-based scientific ideation. Starting from user-provided papers, Scideator extracts key facets -- purposes, mechanisms, and evaluations -- from these and related papers, allowing users to interactively recombine facets to synthesize ideas. Scideator is driven by three design choices: (1) human-in-the-loop facet recombination, in which users select facets from retrieved papers and the system generates ideas by finding analogies across them via the Faceted Idea Generator module; (2) distance-controlled retrieval via the Analogous Paper Facet Finder module, which surfaces papers ranging from the same topic to entirely different areas to provide a spectrum of directions; and (3) facet-based novelty verification via the Idea Novelty Checker module, a retrieve-then-rerank pipeline that helps users to evaluate idea originality using facets. In a user study with computer science researchers, Scideator provided significantly more creativity support than a baseline using the same backbone LLM without our facet-based modules, particularly in idea exploration and expressiveness. Ablations further show that the facets benefit the novelty checker: facet-based retrieve-then-rerank surfaces more relevant papers than standard retrieval and re-ranking, and a facet-grounded novelty classifier outperforms classifiers that reason over unstructured ideas and papers.","external_url":"https://arxiv.org/abs/2409.14634","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-25T04:50:21.943778+00:00","pith_arxiv_id":"2409.14634","created_at":"2026-05-11T05:21:01.570585+00:00","updated_at":"2026-05-25T04:50:21.943778+00:00","title_quality_ok":true,"display_title":"Scideator: Human-llm scientific idea generation grounded in research-paper facet recombination","render_title":"Scideator: Human-llm scientific idea generation grounded in research-paper facet recombination"},"hub":{"state":{"work_id":"05f421d4-c2b4-4aee-a14e-92ac43926fc8","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":12,"external_cited_by_count":null,"distinct_field_count":5,"first_pith_cited_at":"2025-05-27T06:36:04+00:00","last_pith_cited_at":"2026-05-22T03:40:30+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-06-05T21:09:41.981108+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":6}],"polarity_counts":[{"context_polarity":"background","n":5},{"context_polarity":"unclear","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
