My concern is more specific and internal: the survey's own Tables VIII–X contain a counterexample to the absolute gap claim. This is not merely a question of whether another reviewer would classify systems differently; it is a question of whether the paper's stated conclusion is compatible with its own evidence table. If [188] is correctly classified, then 'no dedicated approaches' and 'without exception' are overclaims. If it is not correctly classified, the classification methodology is too subjective to support the existence claim. Either way, the central thesis should be tempered from absence to scarcity. The taxonomies, architecture, and metric framework remain useful independent contributions, and the gap may well be real when framed as 'underdeveloped' rather than 'nonexistent.' Therefore I retain the reader's CONDITIONAL verdict rather than moving to accept or reject: the paper should be revised to acknowledge [188] and to validate the coding protocol, but the core survey value does not collapse.","tokens_in":46244,"tokens_out":3538,"duration_ms":40456,"concrete_test":"Re-code [188] and [88] using the paper's own taxonomy with two independent raters and a pre-registered coding protocol; report inter-rater agreement.

The Section IX Data Market discussion explicitly calls [188] 'an important blueprint' and 'the only model identified that begins to bridge the entity-centric versus data-centric gap.' If the classification is accurate, the central claim is false in its current absolute form: at least one dedicated TRMS for data sharing integrates both missing dimensions.

It defines trust, trustworthiness, and reputation; introduces a four-layer TRMS architecture for data sharing; proposes taxonomies for system design, trust evaluation, and data- and entity-centric metrics; and applies these frameworks to 23 TRMSs across seven domains (VANETs, IoT, MAS, P2P, healthcare, fog/edge, crowdsourcing, social networks, and data markets). The central claim is that existing TRMSs are overwhelmingly entity-centric and lack rigorous data-centric quality assessment and bidirectional evaluation of consumer compliance, and that no dedicated TRMS for data sharing has been proposed. The paper closes with open research directions, including explainability, compliance as a trust metric, and security by design.","tokens_in":46519,"tokens_out":5232,"duration_ms":58827,"significance":"If the central gap claim is stated accurately, the survey makes a useful contribution: it provides clear definitions (Definitions 2.1–2.8), a structured architecture (Fig. 1), two novel taxonomies (Figs. 2 and 4), and systematic comparison tables (Tables IV–XI) that make the field's coverage testable. The forward-looking sections on LLM-based compliance monitoring and explainable trust evaluation are concrete and useful. The paper does not claim machine-checked proofs or code, but its detailed tabular coding of 23 systems is a strength because it enables readers to inspect the evidence behind the claimed gap.","major_comments":[{"comment":"The central claim is an existence claim and is contradicted by the paper's own evidence.

First, this is a genuinely useful survey: it builds a data-sharing-specific lens on TRMSs, proposes a layered architecture, and offers taxonomies for system design, evaluation framework, and data/entity metrics that prior surveys don't have. The cross-domain comparison tables (IV–XI) are carefully assembled, and the gap analysis, though overstated, points at a real and under-served direction: data quality and consumer-side compliance are rarely treated as first-class signals. Second, the central claim as written is too strong and, more importantly, internally contradicted. The abstract says 'there have not been dedicated approaches to data sharing' and the Section IX summary says evaluation frameworks are 'without exception, overwhelmingly entity-centric' and 'consistently overlook' data-centric quality and bidirectional compliance. But the authors' own Table VIII codes Chowdhury et al. [188] (2019) as a Combined, Bidirectional, purpose-built data-market TRMS with support for Compliance and Consent, and the Data Market discussion calls it 'the only model identified that begins to bridge the entity-centric versus data-centric gap.' You can't have both 'without exception' and 'the only model identified' unless 'exception' means something special. If the classification is right, the existence claim is false; if it's wrong, the binary tables are too unreliable to support the gap claim. Either way, the absolute phrasing should be weakened to 'rare' or 'underdeveloped,' with [188] acknowledged as a partial counterexample.\n\nOther soft spots are the usual survey issues: 23 papers across 7 domains is a small sample, the binary support marks are qualitative and not validated by inter-rater agreement, and a few N/A cells in the tables suggest the coding protocol wasn't consistently applied. The proposed architecture in Fig. 1 is nice but it's a vision, not a validated design, and the paper doesn't claim otherwise. The self-citations are not load-bearing, and the prior-survey comparison (Table III) is legitimate.\n\nGiven that, the paper is still worth a serious referee. The taxonomies and the data-sharing perspective are valuable enough that a careful revision, with the central thesis tempered and the counterexample handled honestly, would be a solid contribution. I'd send it to peer review with a request for major revision on the framing.","headline":"Useful data-sharing survey with a solid taxonomy, but the central 'no dedicated approaches' claim is internally contradicted by the authors' own classification of [188].","tokens_in":46938,"tokens_out":2108,"would_cite":true,"duration_ms":22686,"reading_group":"maybe","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"Existing trust-and-reputation systems for data sharing evaluate the people, not the data.","keywords":["trust and reputation management systems","data sharing","data quality assessment","entity-centric vs data-centric evaluation","bidirectional trust evaluation","privacy-preserving trust","TRMS taxonomy","trust evaluation metrics"],"falsifier":"A concrete way to test the gap claim: if a literature search in data-sharing contexts—data marketplaces, federated learning, health data exchange—surfaces a substantial number of TRMSs that already compute data-quality scores for the shared asset and also evaluate consumer compliance with bilateral ratings, then the claimed 'consistent gap' loses its force.

The authors try to establish that this one-sided focus is a systematic gap across the entire literature, not just a limitation of a few systems. To make the gap visible, they contribute a four-layer TRMS architecture for data-sharing ecosystems, two new taxonomies for system design and trust evaluation, and a unified set of data-centric and entity-centric evaluation metrics.
