Alaska
收藏资源简介:
Alaska数据集是由罗马第三大学的研究团队创建,包含近70,000个产品规格,这些数据从71个不同的网络数据源中提取,覆盖相机、显示器和笔记本电脑三个领域。数据集通过三个步骤构建:首先使用Dexter聚焦爬虫发现和爬取网络数据源;其次,通过定制方法从网页中提取产品规格;最后,由领域专家手动策划基准任务的地面真相。Alaska数据集支持多种数据集成任务,特别关注模式匹配和实体解析,旨在评估和促进更全面的数据集成解决方案的设计。
The Alaska dataset was created by a research team from Roma Tre University. It contains nearly 70,000 product specifications extracted from 71 distinct web data sources, covering three domains: cameras, displays, and laptops. The dataset is constructed via three sequential steps: first, the Dexter focused crawler is used to discover and crawl web data sources; second, customized methods are applied to extract product specifications from web pages; finally, domain experts manually curate the ground truth for benchmark tasks. The Alaska dataset supports multiple data integration tasks, with a particular focus on schema matching and entity resolution, aiming to evaluate and facilitate the development of more comprehensive data integration solutions.
