# MemoryCtrl Evaluation Dataset

## Dataset Summary

MemoryCtrl is a synthetic benchmark for studying memory control in personalized LLM settings. It is designed around a simple but important tension: in long-running personalized interactions, some past information is helpful for personalization, but not everything the user says should necessarily be stored, retained, or reused forever. A central question behind the benchmark is whether users can explicitly control the memory behavior of personalized LLMs, and how reliably systems follow those controls.

The benchmark synthesizes persona-grounded users interacting with a personalized assistant under different usage topics. In the `travelPlanning` subset released here, the user interacts with the assistant about trip planning, accommodation, budgets, insurance, schedules, preferences, logistics, and related travel needs. More generally, the benchmark is meant to capture situations where:

- the user provides personal or sensitive details in order to complete a task with the assistant
- the information is useful and necessary at the time of the request
- later retention or reuse of the same information may be undesirable

MemoryCtrl focuses on three memory-control settings:

- `no_store`: the system should not store certain information when it is first revealed
- `forget`: the system previously had access to information but should later forget or remove it
- `no_use`: the system may still retain the information internally but should avoid using it when the user requests that behavior

This Hugging Face release contains source conversations together with QA tables used for evaluation. It does not contain edited conversations, because conversation editing is applied dynamically under different evaluation conditions.

For the quality-check and repair prompt templates used in the current pipeline, see [quality_check_prompts.md](./quality_check_prompts.md).

At a high level, the evaluation workflow is:

1. Start from a source conversation history that contains target interactions relevant to memory-control evaluation.
2. Apply a memory-control operation to those target interactions, such as `no_store`, `forget`, or `no_use`.
3. Evaluate what the system still remembers using QA instances derived from the original conversation. A typical evaluation prompt is structured as follows:

```text
system: Current user persona: [Expanded Persona]

[Edited conversation history up to the evaluation point]
user: ...
assistant: ...
user: ...
assistant: ...

...

user: [Question]

Find the most appropriate response and give your final answer (a), (b), or (c) after the special token <final_answer>.

(a) ...
(b) ...
(c) ...
```

## Dataset Structure

### Data Instances

This repository is organized into three dataset configs:

```text
conversations/
data.parquet
whole_recall_mcq/
test.parquet
slot_recall_mcq/
test.parquet
```

These three files serve different roles:

- `conversations/data.parquet` stores the source conversation history for each persona under the topic.
- `whole_recall_mcq/test.parquet` stores one question per target interaction and asks whether the system remembers what that interaction was broadly about.
- `slot_recall_mcq/test.parquet` stores one question per sensitive detail and asks whether the system remembers a specific value from that interaction.

The relationship between them is:

- one row in `conversations/data.parquet` corresponds to one persona-topic conversation
- one conversation row maps to many whole-recall questions because the conversation contains many target interactions
- one whole-recall target interaction may map to multiple slot-recall questions because a single interaction can contain multiple detail values

The terms `key` and `probe` appear in the evaluation metadata:

- `key`: an interaction targeted for memory-control testing, often because it contains information that should not be stored, should later be forgotten, or should not be used
- `probe`: an interaction used to test retained utility or ordinary recall behavior on allowed information

##### Dataset Statistics

- `conversations`: 10 rows
- `whole_recall_mcq`: 60 rows
- `slot_recall_mcq`: 362 rows

Different subsets of MemoryCtrl can synthesize different usage topics over the same underlying persona set. This release covers the `travelPlanning` topic only.

### `conversations/data.parquet`

This table is the source context table (i.e., from which edited histories and downstream evaluation instances are derived). Each row contains one complete multi-stage conversation for a specific persona-topic pair, together with persona metadata and serialized history structures from the original synthesis pipeline.

One row corresponds to one baseline conversation file such as `conversation_travelPlanning_persona0_sample0.json`.

#### How To Read The Conversation Content

The main conversation content is in `conversation`.

- lines beginning with `User:` are ordinary user turns.
- lines beginning with `Assistant:` are ordinary assistant turns.
- lines beginning with `Side_Note:` are synthetic annotations carried over from the generation pipeline. It will not be included in the real conversation used for evaluation. Instead, it is just used for data inspection.

### `whole_recall_mcq/test.parquet`

This table evaluates whether a system remembers what an earlier `key` or `probe` interaction was broadly about. (Recall that `key` is an interaction targeted for memory-control testing, and `probe` is an interaction used to test retained utility or ordinary recall behavior on allowed information.) It does not ask about exact values such as dates, budgets, or email addresses. Instead, it tests memory of the overall request.

For example, if an earlier turn was about finding cost-effective accommodation in Paris, the whole-recall question asks whether the system remembers that the user wanted help with a Paris stay, not whether it remembers the exact budget or travel dates.

## Dataset Creation

### Source Data

The exported data in this release is derived from the `travelPlanning` subset of MemoryCtrl. At a high level, the dataset is created as follows:

1. Start from personas drawn from the [PersonaHub dataset](https://huggingface.co/datasets/AmaliaE/PersonaHub).
2. Expand each seed persona into a richer persona profile.
3. Generate a personal history for the expanded persona.
4. Based on the persona and personal history, construct the kinds of everyday conversations, preferences, and topic-related facts that this person might naturally share under a given usage topic.
5. For a subset of interactions that are suitable for expansion, design help-seeking interactions in which the user asks the assistant to complete a concrete task. These interactions are the main places where sensitive details are naturally revealed, because such details are often necessary to complete the task.
6. Combine the ordinary day-to-day interactions with the help-seeking interactions to form a full conversation trajectory for that persona under the topic.

For this Hugging Face release, the final conversation files are then reshaped into three evaluation-oriented tables:

- `conversations/data.parquet`: full source conversations
- `whole_recall_mcq/test.parquet`: one question per target interaction, testing recall of the overall request
- `slot_recall_mcq/test.parquet`: one question per sensitive detail, testing recall of a specific value

### How This Dataset Is Used In Evaluation
A typical evaluation loop is:

1. load each row from `conversations/data.parquet`
2. insert the memory insturctions (corresponding to `no_store`, `forget`, or `no_use`) to the `key` turns in the conversations
3. present the conversation to the personalized model or memory system and ask the corresponding questions from `whole_recall_mcq/test.parquet` or `slot_recall_mcq/test.parquet`
5. score whether the system incorrectly recalls the forbidden information, or no longer remembers the allowed information

The exact memory-edit implementation is intentionally outside the dataset because it depends on the model architecture, memory backend, and experiment design.

### Personal and Sensitive Information

Some rows include synthetic test-only PII in persona or interaction fields. These values are synthetic.

数据集介绍

构建方式

在个性化大语言模型的研究领域中，MemoryCtrl数据集通过合成方法构建，旨在探究用户对系统记忆行为的控制能力。该数据集围绕虚构人物与个性化助手在特定主题下的交互展开，当前发布的travelPlanning子集聚焦于旅行规划场景。构建过程首先生成包含目标交互的原始对话历史，随后针对这些交互应用三种记忆控制操作——不存储、遗忘或不使用，最终基于原始对话衍生出用于评估的多选题实例，从而形成结构化的评估基准。

特点

MemoryCtrl数据集的核心特点在于其专注于记忆控制这一新兴研究方向，系统考察了不存储、遗忘和不使用三种关键场景。数据集通过精心设计的合成人物和交互，模拟了用户提供敏感信息以完成任务，但后续可能希望限制这些信息被保留或使用的真实情境。其评估框架包含整体回忆和细节回忆两个层面，分别通过whole_recall_mcq和slot_recall_mcq两个配置文件实现，能够细致地量化系统对交互整体内容和具体敏感细节的记忆程度，为评估个性化模型的记忆可控性提供了多维度的测量工具。

使用方法

使用MemoryCtrl数据集进行评估时，研究者需遵循特定的工作流程。首先加载conversations配置文件中的原始对话数据，这些数据包含了人物元信息和序列化的交互历史。随后，根据研究需求对目标交互施加指定的记忆控制操作，动态编辑对话历史。评估阶段则利用whole_recall_mcq和slot_recall_mcq中的多选题实例，测试系统在编辑后的历史背景下对先前信息的记忆保持情况。评估提示词会呈现编辑后的对话历史，并要求模型在给定的选项中选择最恰当的回应，从而客观衡量系统遵循用户记忆控制指令的可靠性。

背景与挑战

背景概述

在个性化大语言模型（LLM）的长期交互场景中，如何有效控制模型对用户信息的记忆行为，已成为人工智能伦理与隐私保护领域的前沿议题。MemoryCtrl数据集应运而生，旨在系统化评估个性化LLM在用户显式指令下对记忆的存储、遗忘与使用控制能力。该数据集围绕一个核心矛盾构建：在个性化服务中，部分历史信息有助于提升体验，但并非所有用户透露的敏感细节都应被永久保留或复用。通过合成基于人物角色的对话，尤其在旅行规划等具体话题中，MemoryCtrl模拟了用户提供必要但敏感信息以完成任务，而后又希望限制这些信息后续使用的典型情境。其设计聚焦于三种记忆控制设定：不存储、遗忘与不使用，为研究社区提供了首个专注于记忆可控性的合成评测基准。

当前挑战

MemoryCtrl数据集致力于解决个性化人工智能系统中记忆可控性这一新兴领域问题，其核心挑战在于如何精准评估模型对用户显式记忆指令的遵循程度。这要求评测框架不仅能区分模型是否记住了信息，还需辨别记忆是源于用户允许保留的内容，还是本应被控制的信息。在数据集构建过程中，挑战同样显著：合成既真实又涵盖敏感细节的对话需要平衡隐私保护与数据效用；确保多轮对话中‘关键交互’与‘探测交互’的逻辑连贯性与评估针对性；以及设计能够无歧义映射到具体记忆控制操作（如不存储、遗忘）的评测问题。这些挑战共同指向了构建可靠、公正的记忆控制评估基准的复杂性。

常用场景

经典使用场景

在个性化大语言模型的研究领域，MemoryCtrl数据集为评估模型记忆控制能力提供了标准化测试框架。该数据集围绕旅行规划场景构建，模拟用户与助手之间包含敏感信息的长期交互过程。研究者通过设计三种记忆控制操作——不存储、遗忘和禁止使用，系统性地考察模型对用户指定信息的处理依从性。这种评估范式能够精确测量模型在动态对话中区分应保留与应遗忘信息的能力，为个性化人工智能的记忆管理机制研究奠定了实证基础。

解决学术问题

MemoryCtrl数据集有效解决了个性化人工智能领域的关键理论难题：如何在保证服务效能的同时尊重用户的记忆自主权。该数据集通过结构化评估方案，量化分析模型对敏感信息的记忆保持程度，为研究记忆控制与隐私保护的平衡关系提供了可验证的途径。其重要意义在于建立了标准化评估指标，使得不同记忆控制策略的效果能够进行横向比较，推动了可解释、可审计的个性化系统设计范式的形成，对构建负责任的人工智能系统具有深远影响。

衍生相关工作

该数据集的发布催生了多个重要的衍生研究方向。学者们基于其评估框架开发了新型记忆控制算法，包括动态记忆门控机制和差分隐私增强的记忆管理系统。相关研究进一步扩展了记忆控制的应用场景，如将其适配于多轮教育对话和心理健康支持系统。这些工作深化了对人机交互中信任建立机制的理解，推动了可撤销记忆、情境感知遗忘等前沿概念的技术实现，为下一代个性化人工智能系统的安全部署提供了理论依据和实践指南。
