CRA-Bench
CRA-Bench is a benchmark for evaluating LLM-based conversational recommender agents under ambiguous user intent in realistic, web-grounded shopping environments. It focuses on whether agents can clarify underspecified user needs, interact with retrieval tools, recover latent product-level constraints, and recommend suitable items through multi-turn interaction.
CRA-Bench is built on Amazon Reviews 2023 and is designed around a large-scale product space of more than two million products. The released benchmark contains task definitions, user profiles, recommender-visible profiles, ambiguity-controlled initial queries, fuzzy target grounding, difficulty settings, and evaluation-only target labels.
Dataset Description
Conversational recommender systems are increasingly moving from static item matching to agentic interaction, where systems need to ask clarification questions, search candidate products, refine user intent, and produce recommendations across multiple turns. Existing evaluation settings often assume overly explicit user inputs, lack controllable task-difficulty modeling, or focus mainly on final item matching.
CRA-Bench is designed to evaluate whether recommender agents can recover latent user needs through interaction. It emphasizes three properties:
- Controlled ambiguity construction: the initial query expresses the same underlying user need with different levels of specificity.
- Fuzzy target grounding: the user simulator is grounded in partial and everyday descriptions of the target need rather than exact product identifiers.
- Multi-dimensional difficulty modeling: task difficulty is controlled through both query ambiguity and user behavior factors such as cooperativeness, patience, dissatisfaction sensitivity, and reasoning exposure.
Dataset Structure
The dataset contains three difficulty splits:
data/easy.jsonl
data/medium.jsonl
data/hard.jsonl
Each line is a JSON object corresponding to one benchmark session.
The main fields are:
| Field | Description |
|---|---|
user_id |
An anonymized or pseudonymous user identifier. |
task |
Task-level information, including the initial query and behavior profile. |
user_profile |
Simulator-side user profile used by the user simulator. |
recsys_profile |
Recommender-visible user profile available to the recommender agent. |
fuzzy_gt |
Fuzzy target grounding and evaluation-only target information. |
Field Schema
user_id
A pseudonymous identifier for the user history from which the benchmark session is constructed. This field should not be interpreted as a real-world identity.
task
The task field contains the initial user request and behavior-control settings.
Typical subfields include:
| Subfield | Description |
|---|---|
opening_query or initial_query |
The ambiguity-controlled initial user request. In the paper, this is referred to as the initial query. |
behavior_profile |
User behavior parameters used to control interaction difficulty. |
The behavior profile may include:
| Behavior factor | Description |
|---|---|
purchase_intent_clarity |
How clearly the user expresses the intended product need. |
cooperativeness |
How willing the user is to answer clarification questions. |
initial_patience |
The initial patience budget of the simulated user. |
dissatisfaction_sensitivity |
How sensitive the user is to irrelevant or low-quality recommendations. |
reasoning_exposure |
How explicitly the user reveals reasoning or preference information. |
user_profile
The user_profile field is used by the user simulator. It represents richer simulator-side information derived from historical interactions and target-session context.
It may include information such as:
- long-term category interests;
- price sensitivity;
- preferred brands;
- decision factors;
- current usage scenario;
- user-perceived product type;
- fuzzy descriptions of the target need.
This field should not be exposed to the recommender agent.
recsys_profile
The recsys_profile field is visible to the recommender agent. It represents information that a recommender system may reasonably access before or during the session.
It may include information such as:
- long-term shopping interests;
- price sensitivity;
- brand preferences;
- focus aspects;
- diversity preference;
- recent shopping interests;
- short-term focus aspects;
- consistency with long-term preferences.
fuzzy_gt
The fuzzy_gt field contains fuzzy target grounding and evaluation-only information.
It may contain:
| Subfield | Description |
|---|---|
simulator_visible |
Fuzzy target information available to the user simulator. |
evaluation_only |
Exact target labels or identifiers used only for metric computation. |
The evaluation_only fields must not be exposed to the recommender agent during interaction.
Visibility Rules
CRA-Bench separates recommender-visible, simulator-visible, and evaluation-only information.
Recommender-visible information
The recommender agent may access:
task.opening_queryortask.initial_query;task.behavior_profile, if used by the experimental protocol;recsys_profile;- dialogue history;
- retrieved candidate products returned by the retrieval tool.
Simulator-visible information
The user simulator may access:
user_profile;task.behavior_profile;fuzzy_gt.simulator_visible;- dialogue history.
Evaluation-only information
The following fields are used only for metric computation and must not be exposed to the recommender agent during interaction:
fuzzy_gt.evaluation_only.target_asin;- other exact target identifiers, if provided.
The released dataset includes true target labels under fuzzy_gt.evaluation_only. These fields are intended only for evaluation and should not be used as recommender-visible inputs.
Difficulty Splits
CRA-Bench defines three difficulty levels:
Easy
Medium
Hard
The difficulty levels vary both the ambiguity of the initial query and the interaction behavior of the simulated user.
In general:
- Easy sessions contain more explicit product cues and more cooperative user behavior.
- Medium sessions introduce more ambiguity and require more effective clarification.
- Hard sessions contain less direct target information and stricter interaction conditions.
The difficulty construction is designed so that the same underlying recommendation need can be expressed under different levels of ambiguity and interaction difficulty.
Fuzzy Target Grounding
Fuzzy target grounding prevents the user simulator from directly exposing oracle-style product identifiers or exact target attributes, such as exact titles, ASINs, model numbers, or overly specific specifications.
Instead, the simulator is grounded in partial, experiential, and everyday descriptions of the target need.
For example, rather than exposing an exact product title or identifier, the simulator may describe the need as:
I want something breathable and soft for everyday wear, especially because rough seams bother me during long days.
This design encourages agents to recover latent user needs through clarification and interaction rather than relying on direct string matching with the target product.
Evaluation Protocol
CRA-Bench evaluates conversational recommender agents in a web-grounded product environment with retrieval tools and user simulation.
A typical evaluation session proceeds as follows:
- The user simulator provides an ambiguity-controlled initial query.
- The recommender agent asks clarification questions, invokes a retrieval tool, or recommends items according to the experimental protocol.
- The user simulator responds based on simulator-visible profile information and fuzzy target grounding.
- The recommender agent produces a final ranked recommendation list.
- Evaluation metrics are computed using evaluation-only target labels.
The benchmark is designed to distinguish different sources of failure, including:
- retrieval failure;
- ranking failure;
- ineffective clarification;
- premature recommendation;
- failure to infer latent product constraints.
Metrics
CRA-Bench supports both final recommendation metrics and process-level interaction metrics.
Final recommendation metrics
| Metric | Description |
|---|---|
RecallHit |
Whether the target item is retrieved by the retrieval module at any point. |
Recall@5 |
Whether the final top-5 recommendation list contains the target item. |
NDCG@5 |
Rank-sensitive quality of the final top-5 recommendation list. |
Interaction cost metrics
| Metric | Description |
|---|---|
Avg. Turns |
Average number of completed recommender-user exchange turns, excluding the initial request. |
Avg. Chars |
Average number of recommender-generated characters per session. |
Process-level metrics
| Metric | Description |
|---|---|
Question Relevance |
Whether the agent's questions or responses advance the current recommendation task. |
Latent Need Alignment |
Whether the recommendations align with the user's latent target need. |
Conversation Efficiency |
Whether the agent reaches useful recommendations with reasonable interaction cost. |

The exact field names may vary slightly across released files. Users should follow the visibility rules when constructing evaluation pipelines.
Large-scale Product Environment
CRA-Bench is built on Amazon Reviews 2023 over a large-scale product space of more than two million products. The released task files contain benchmark sessions and evaluation labels.
The large-scale retrieval catalog is derived from Amazon Reviews 2023 using the filtering, metadata alignment, and indexing procedure described in the paper and accompanying code.
If the full retrieval catalog is not included in this repository due to size or redistribution constraints, users should reconstruct it from Amazon Reviews 2023 using the provided scripts, schema documentation, and filtering settings.
Intended Use
CRA-Bench is intended for research on:
- conversational recommender systems;
- LLM-based recommender agents;
- proactive clarification;
- tool-based retrieval;
- user simulation;
- latent need recovery;
- interaction-centered evaluation;
- benchmark analysis for agentic recommendation.
Out-of-Scope Use
CRA-Bench should not be used for:
- real-world user profiling;
- commercial targeting;
- inferring sensitive user attributes;
- making production recommendation decisions without additional validation;
- re-identifying users from shopping behavior;
- training systems intended to manipulate user preferences.
Limitations
CRA-Bench has several limitations:
- It focuses on selected Amazon product domains and does not cover all e-commerce categories.
- It is primarily designed for English shopping interactions.
- It does not model all forms of multimodal browsing behavior, such as image inspection, scrolling, or visual comparison.
- It does not directly interact with real-time commercial search engines.
- The user simulator and process-level evaluator may reflect limitations and biases of the LLMs and prompts used in the construction pipeline.
- Results on CRA-Bench should not be interpreted as direct evidence of production recommender performance without additional validation.
Biases and Ethical Considerations
Because CRA-Bench is derived from Amazon Reviews 2023, it may inherit biases from the source data, including:
- product popularity bias;
- reviewer self-selection bias;
- domain imbalance;
- language and cultural bias;
- uneven brand coverage;
- uneven price distribution;
- product availability bias.
Generated profiles, initial queries, fuzzy target descriptions, and simulated interactions may further introduce biases from the generation pipeline.
CRA-Bench is not intended to contain directly identifying personal information. User identifiers should be treated as anonymized or pseudonymous identifiers. However, shopping behavior may indirectly reflect preferences or demographic patterns. Users should not attempt to re-identify individuals or infer sensitive attributes from the dataset.
