Intuitive Datasets: Five-Level Data Abstraction Transformations Overview This dataset collection demonstrates systematic transformations of open datasets across five levels of abstraction (L4→L0→L3), enabling users with different data literacy levels to access and understand complex data. The transformations implement a meta-design framework for creating "intuitive datasets" that adapt their complexity to user needs.

直观数据集:五级数据抽象变换 ## 概述 本数据集集合展示了开放数据集在五级抽象层级(L4→L0→L3)下的系统性变换,可适配不同数据素养水平的用户访问与理解复杂数据。该变换实现了一套元设计框架,用于构建“直观数据集”,使其能够根据用户需求动态调整自身复杂度。 ## 引用 若使用本数据集,请引用:10.5281/zenodo.18174814 ## 许可协议 CC-BY-4.0(知识共享署名4.0国际许可协议) ## 相关代码 https://github.com/ArthurSrz/intuitiveness ## 包含的数据集 本集合包含来自法国开放数据平台data.gouv.fr的三套完整数据集变换循环: - test0_schools:法国中学绩效指标与学生入学数据 - test1_ademe:法国环境署(ADEME)资助拨款数据 - test2_energy:法国天然气关税能源价格数据 ### 单数据集结构 每个数据集均包含以下目录: - `raw/`:原始L4文件(data.gouv.fr上的不可关联多级数据集) - `descent/`:经L3(可关联数据集)、L2(分类表)、L1(特征向量)、L0(原子数据)层级变换得到的文件 - `ascent/`:从L0逆向重构至L3的数据集,并新增分析维度 - `metadata/`:变换元数据、会话导出文件与关联规范 ## 五级抽象框架 本框架定义了五级数据抽象层级: 1. **L4(层级4)**:不可关联多级数据集——多个无明确结构的断开式CSV文件 2. **L3(层级3)**:可关联多级数据集——通过关联关系连接形成知识图谱的文件集合 3. **L2(层级2)**:包含多实体与多属性的单数据集——经分类或筛选的结构化表格 4. **L1(层级1)**:单实体或单属性——特征向量或实体概览 5. **L0(层级0)**:原子数据——单实体-属性-值三元组(例如“平均学校得分:12.5”) ## 降维阶段(L4→L0) 该阶段逐步降低数据复杂度: - L4→L3:实体发现与关系检测,用于连接断开的原始文件 - L3→L2:通过语义分类实现领域隔离 - L2→L1:特征提取以生成标准化向量 - L1→L0:聚合操作以推导原子指标 ## 升维阶段(L0→L3) 该阶段有意重构数据复杂度: - L0→L1:将原子数据扩展为包含相关属性的特征向量 - L1→L2:添加分类维度(例如“高/低绩效”) - L2→L3:添加分析维度以构建多级数据结构 ## 文件命名规范 所有文件均遵循格式:`{dataset}_{level}_{description}.{ext}` 示例: - `test0_schools_L4_fr-en-college-effectifs-niveau-sexe-lv.csv`:原始L4格式文件 - `test0_schools_L3_joined_table.csv`:L3层级关联表格 - `test0_schools_L0_datum.json`:L0层级原子数据文件 - `test0_schools_ascent_L3_table.csv`:升维阶段重构的L3层级表格 ## 数据来源 所有数据集均源自法国国家开放数据平台data.gouv.fr: 1. test0_schools: - 按层级、性别与语言划分的中学入学人数:https://www.data.gouv.fr/datasets/effectifs-deleves-par-niveau-sexe-langues-vivantes-1-et-2-les-plus-frequentes-par-college-date-dobservation-au-debut-du-mois-doctobre-chaque-annee - 中学绩效指标:https://www.data.gouv.fr/datasets/indicateurs-de-valeur-ajoutee-des-colleges 2. test1_ademe: - ADEME财政资助拨款:https://www.data.gouv.fr/datasets/les-aides-financieres-de-lademe-1 - ADEME资助项目列表:https://www.data.gouv.fr/datasets/couts-des-travaux-de-renovation-ecs 3. test2_energy: - 法国城镇管制天然气关税价格层级:https://www.data.gouv.fr/datasets/niveaux-de-prix-par-commune-pour-les-tarifs-reglementes-de-vente-de-gaz-naturel-dengie - 法国2005-2021年能源进出口数据:https://www.data.gouv.fr/datasets/imports-et-exports-commerciaux-2005-a-2021 ## 变换方法 本次变换使用`intuitiveness` Python包(v0.1.0)完成,依赖项如下: - Python 3.11 - pandas 2.x - networkx 3.x - sentence-transformers(multilingual-e5-small 模型) 如需了解详细变换逻辑,请参阅各数据集`metadata/`目录下的会话导出文件。 ## 复用场景示例 ### 面向数据科学家 - 在不同复杂度层级下测试数据变换算法 - 基准测试复杂度缩减指标 - 验证语义领域匹配技术 - 在多级数据结构上训练机器学习模型 ### 面向开放数据平台 - 实现多级数据访问功能 - 为不同数据素养水平的用户设计自适应交互界面 - 测试基于复杂度感知的搜索与导航功能 ### 面向教育工作者 - 通过具体示例讲授数据素养概念 - 演示降维-升维变换循环 - 阐释复杂度管理原则 ### 面向研究人员 - 研究数据结构对用户理解的影响 - 分析开放数据集中的关系发现模式 - 跨领域调研语义分类的有效性 ## 联系方式 如有疑问、问题或建议,请联系:arthur.sarazin@etu-iepg.fr
