0 catalogued patent records
Coverage: No attributable record found in this search
Exact-name patent and Google Patents-domain searches produced no attributable inventor entry. A patent-related result citing an Ori Ernst paper is not inventor evidence. BIU article reopening failed; no absence inference was made. Baseline NLP identity remains preserved.
No publication records verified in this search; this does not establish absence of patents.
Original evidence: not verified
No attributable patent record was verified in the bounded search.
Records are counted separately from identified families. Author-reported entries are labelled and may still need publication verification. Inventorship, publication-time applicant and current ownership are different facts. No legal-status, patentability or freedom-to-operate conclusion is made.
Scores prioritize research fit from 1–10; they are not probabilities.
Review: Reviewed with limitations
Proposed capability matches, not confirmed relationships. Scores are analyst judgments with low forecast confidence; researcher interests, capacity and feasibility need confirmation.
11 candidates
Connection 1
Original proposal
Proposal hypothesis: Ernst's proposition-to-source alignment supplies auditable units for Fetaya's adversarial evaluation; the shared question is whether a summarizer preserves support under misleading input.[73][93][94][95]
Proposed first test: Corrupt one supporting passage in an open multi-document corpus and compare unsupported propositions and retained counterevidence against an unaligned summarizer.
Rank 1/11; fit 10/10 (4 topic overlap + 3 complementarity + 3 feasible first test). Preserved original co-membership proposal in o01. No strictly higher-scoring candidate displaces this original. A public-text benchmark is straightforward; robustness beyond the selected corruption family remains untested. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 2
Original proposal
Proposal hypothesis: Ernst supplies proposition clusters and Goldberger supplies statistical language modelling and uncertainty estimation to decide which summary statements need review.[75][76][93][94][95]
Proposed first test: On an adjudicated open corpus, compare uncertainty-based review with random review at the same budget; measure unsupported statements missed.
Rank 2/11; fit 9/10 (4 topic overlap + 2 complementarity + 3 feasible first test). Preserved original co-membership proposal in o01. Higher-scoring Ethan Fetaya (10/10) precedes this original; its own rank reflects the following limitation: Strong NLP overlap, with partially overlapping modelling roles rather than a new measurement modality. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 3
Proposal hypothesis: Somin can identify temporal event structure and Ernst can preserve source support when summarizing network incidents.[64][65][93][94][95]
Proposed first test: Create a synthetic timestamped incident corpus and compare event-grounded summaries with ordinary summaries on ordering errors and unsupported links.
Rank 3/11; fit 8/10 (2 topic overlap + 3 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. Temporal association must not be rewritten as causal coordination or malicious intent. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 4
Proposal hypothesis: Singer can specify a decision policy and its cost tradeoffs while Ernst can link an explanatory summary to the actual policy inputs and outputs.[79][80][93][94][95]
Proposed first test: Generate synthetic allocation cases and compare source-aligned explanations with ordinary summaries on omitted constraints and incorrect cost statements.
Rank 4/11; fit 8/10 (2 topic overlap + 3 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. A faithful explanation does not prove that the underlying policy is optimal or fair. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 5
Proposal hypothesis: Izack Cohen's process and queueing model can produce auditable events that Ernst summarizes without inventing bottleneck causes.[93][94][95][97][98]
Proposed first test: Summarize synthetic queue logs with known bottlenecks and compare proposition alignment with ungrounded narrative on causal overstatement.
Rank 5/11; fit 8/10 (2 topic overlap + 3 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. Simulation supports controlled testing only; actual hospital process access is unconfirmed. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 6
Proposal hypothesis: Ilan Cohen's online allocation decisions provide explicit constraints and state changes for Ernst's proposition-aligned explanations.[93][94][95][119][120]
Proposed first test: Compare summaries of synthetic scheduling traces on constraint attribution, missed exceptions and unsupported fairness statements.
Rank 6/11; fit 8/10 (2 topic overlap + 3 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. An explanation must distinguish the rule followed from the desirability of the resulting allocation. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 7
Proposal hypothesis: Ernst's source-aligned text and Shavit's multimodal uncertainty direction could test when summaries should abstain if image and text evidence conflict.[93][94][95][127][128]
Proposed first test: On a small open image-caption evidence set, inject mismatches and compare abstention and source-attribution errors with a text-only baseline.
Rank 7/11; fit 8/10 (2 topic overlap + 3 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. This is a transfer hypothesis; Shavit's cited camera-localization work does not establish summarization expertise. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work. Yoli Shavit biological/multimodal programme evidence is a 2025 announcement; current laboratory operation and biological experimental capability are not established.
Connection 8
Original proposal
Proposal hypothesis: Chalutz-Ben Gal's organizational AI-adoption research complements Ernst's traceable summaries by testing whether people use provenance when correcting research advice.[22][23][93][94][95]
Proposed first test: Prepare two versions of ten synthetic research briefs, with and without source alignment, and pilot an error-correction rubric before any approved participant study.
Rank 8/11; fit 7/10 (2 topic overlap + 3 complementarity + 2 feasible first test). Preserved original co-membership proposal in o01. An added candidate, Shahar Somin (8/10), ranks above this original because its stated pair-specific roles and first test score higher; this original is limited as follows: Human evaluation requires consent and a separately scoped use study; citation visibility alone is not evidence of better decisions. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work. Original initiative conditions remain: o01 Hila Chalutz-Ben Gal: Conditional later role: design a separately approved researcher-use study of noticing and correcting unsupported recommendations.
Connection 9
Proposal hypothesis: Kalisky can define biologically meaningful cell-state claims and Ernst can test whether summaries preserve their exact supporting evidence and caveats.[70][93][94][95]
Proposed first test: Adjudicate a small open single-cell paper set and compare source-aligned summaries on state-label accuracy and omitted experimental limitations.
Rank 9/11; fit 7/10 (2 topic overlap + 3 complementarity + 2 feasible first test). New pairing outside the frozen portfolio co-member graph. Domain review is essential; source alignment cannot establish the truth of a biological claim. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 10
Original proposal
Proposal hypothesis: Ernst can specify a source-alignment computation and Mor Weiss can ask whether its execution can be proven without exposing protected inputs; a proof would not establish scientific truth.[93][94][95][123]
Proposed first test: Specify a toy statement that each released sentence maps to an allowed source index; benchmark proof size and verification cost on synthetic inputs.
Rank 10/11; fit 6/10 (1 topic overlap + 3 complementarity + 2 feasible first test). Preserved original co-membership proposal in o01. An added candidate, Shahar Somin (8/10), ranks above this original because its stated pair-specific roles and first test score higher; this original is limited as follows: The original later-stage role needs a protected-input threat model and a tractable proof statement before implementation. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work. Original initiative conditions remain: o01 Mor Weiss: Conditional later role: only after a protected-input threat model exists, specify a computation or access-policy statement that can be proven without revealing inputs.
Connection 11
Identity check needed: Conditional proposal: confirm the researcher identity and research interests before assessing this match.
Proposal hypothesis: Conditional on confirmation, Simonovsky could coordinate an agent-prototype exercise whose source-alignment task and scientific rubric are defined by Ernst.[16][17][93][94][95]
Conditional proposed first test: After identity confirmation, package ten open-text summary tasks with source passages and pilot whether teams can submit auditable outputs.
Rank 11/11; fit 5/10 (1 topic overlap + 2 complementarity + 2 feasible first test). New pairing outside the frozen portfolio co-member graph. Event coordination is documented; NLP research capability and evaluator expertise are not established for Simonovsky. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work. Conditional: confirm Alexandra Simonovsky identity and current role before any team assignment. Evidence supports AI-agent event coordination only; research appointment, teaching role and technical research expertise are not verified. Excluded from confirmed-team claims.

Proposed capability match for Ori Ernst with Gregory Wornell: Task-oriented information compression can target proposition retention, but generic estimation error is not a summary-quality metric and the method transfer remains indirect.[93][94][95][110][503]
Create a small synthetic document set with explicit proposition-to-source truth labels. Compare task-selected evidence snippets with uniform truncation at the same token budget, feeding both into the same summarizer.
