The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

Customer reviews contain signals about service quality, but standard sentiment analysis stays descriptive and direct LLM prompting tends to produce generic, repetitive recommendations that sit loosely on the source data. The paper presents a hierarchical pipeline that assigns separate agents to compress review signals, abstract the underlying problems, generate candidate advice, evaluate outputs against explicit objectives, and route decisions while tracking token cost. This decomposition creates traceable intermediate results and tunable quality-cost balances. Experiments on Yelp reviews across three service domains show the pipeline outperforms single-pass LLM baselines on actionability, relevance, and non-redundancy, while human raters also favor its outputs.

Core claim

By decomposing the task into specialized agents for signal compression, problem abstraction, candidate generation, objective-based evaluation, and cost-aware routing, the pipeline yields advice that is more actionable, relevant, and non-redundant than advice produced by direct prompting of large language models, as measured on Yelp review sets from multiple domains and confirmed in human preference tests.

What carries the argument

The hierarchical decision-support pipeline that separates signal compression, problem abstraction, candidate generation, objective-based evaluation, and cost-aware routing into distinct agents, producing auditable artifacts and controllable quality-cost trade-offs.

Load-bearing premise

Splitting the workflow into separate agents with objective-based evaluation yields advice that is meaningfully better grounded in the reviews than direct prompting rather than merely adding overhead.

What would settle it

A follow-up experiment on the same Yelp domains or new review corpora in which the multi-agent pipeline shows no measurable gains over single-pass LLM baselines on actionability, relevance, or non-redundancy metrics.

Referee Report

2 major / 1 minor

Summary. The paper proposes a hierarchical multi-agent pipeline for converting customer reviews into actionable business advice. It decomposes the workflow into specialized agents for signal compression, problem abstraction, candidate generation, objective-based evaluation, and cost-aware routing. Experiments on Yelp reviews from three service domains report consistent improvements over single-pass LLM baselines on actionability, relevance, and non-redundancy, with additional human evaluation indicating user preference for the pipeline outputs.

Significance. If the empirical results hold, the work demonstrates the practical value of explicit agentic decomposition for producing grounded, auditable advice from review data rather than generic LLM outputs. The cost-aware routing and intermediate artifacts provide controllable trade-offs suitable for real-world business applications, extending beyond descriptive sentiment analysis toward prescriptive decision support.

major comments (2)
  1. [Results] Results section: The central claim of 'consistent improvements' over single-pass LLM baselines across actionability, relevance, and non-redundancy is load-bearing but unsupported by any quantitative metrics, per-domain scores, baseline model specifications, or statistical tests in the provided description. This prevents verification of effect sizes or consistency.
  2. [Human Evaluation] Human evaluation section: The reported user preference lacks protocol details such as evaluator count, rating scales, inter-rater agreement, or statistical comparison to baselines, which are required to substantiate the preference result.

  1. [Abstract] Abstract: Adding one sentence on the specific service domains and review volume would improve context without altering length substantially.

Thank you for the constructive feedback on our manuscript. We address each major comment below and will revise the paper to provide the requested quantitative details and protocol information.

This prevents verification of effect sizes or consistency.

    Authors: We agree that the current manuscript does not include explicit quantitative metrics, per-domain scores, baseline model specifications, or statistical tests. In the revised version, we will add a detailed results table reporting per-domain scores (for the three Yelp service domains) on actionability, relevance, and non-redundancy, specify the exact baseline LLMs and prompting setups used, and include statistical tests (e.g., paired t-tests with p-values) to demonstrate the significance and consistency of the improvements. revision: yes

    Authors: We acknowledge the need for these protocol details. The revised manuscript will specify the number of human evaluators, the exact rating scales employed (e.g., Likert scale for preference), inter-rater agreement statistics (e.g., Fleiss' kappa), and statistical comparisons (e.g., chi-squared tests) between our pipeline outputs and the single-pass baselines. revision: yes

Circularity Check

0 steps flagged

No significant circularity

full rationale

The paper presents an empirical multi-agent pipeline for advice generation from reviews and supports its claims solely through experimental comparisons against single-pass LLM baselines on Yelp data across actionability, relevance, and non-redundancy metrics, plus human preference. No equations, fitted parameters, self-definitional reductions, or load-bearing self-citations appear in the derivation chain; the architectural decomposition is justified by explicit separation of concerns and direct empirical outcomes rather than any circular renaming or imported uniqueness theorem. The central result is therefore self-contained against external benchmarks.

read the original abstract

Customer reviews contain valuable signals about service quality, but converting large-scale review corpora into actionable business recommendations remains difficult. Standard sentiment/aspect analysis is largely descriptive, while direct prompting of large language models (LLMs) often yields generic and repetitive advice that is weakly grounded in user feedback. We propose a hierarchical decision-support pipeline that explicitly separates signal compression, problem abstraction, candidate generation, objective-based evaluation, and cost-aware routing into different agents. This architectural decomposition produces auditable intermediate artifacts and enables controllable trade-offs between advice quality and token budget. Experiments on Yelp reviews from three service domains show consistent improvements over single-pass LLM baselines across multiple advice quality dimensions, including actionability, relevance, and non-redundancy. A human evaluation further indicates that users generally prefer our system's recommendations. These results highlight the value of structured agentic decomposition for scalable, cost-aware business decision support.
