过去十年中，住房成本急剧上升，超过了经济衰退前的水平，但住房研究人员和政策制定者用来了解这些动态的数据在时空粒度或方法透明度方面仍然受到重要限制。虽然现有公共和私人数据源的这些方面对了解美国各地市场的成本和可用性的地理位置构成了障碍，但有关住房机会的网络数据提供了一种重要的替代方案，尽管它需要潜在数据用户可能缺乏的技术技能。本案例研究记录了社会科学家和计算机科学家之间的合作经验，重点是使用一种新颖的网络自动化演示编程工具 Helena，为美国的租赁住房政策和不平等现象提供信息。虽然该项目最初的重点是从西雅图地区的单个地点收集住房广告，但海伦娜以人为本的设计提供了将我们的项目扩展到新来源和地点的能力，使社会科学家团队能够在全国范围内和多个平台上抓取数据。以此项目作为案例研究，我们讨论 a.) 遇到的重要编程和研究挑战，以及 b.) Helena 的设计如何帮助我们克服在基础研究和政策分析中使用抓取的网络数据的障碍。
Housing costs have risen dramatically in the past decade, surpassing their pre-Recession levels, but the data that housing researchers and policymakers rely on to understand these dynamics remain subject to important limitations in their spatiotemporal granularity or methodological transparency. While these aspects of existing public and private data sources present barriers to understanding the geography of cost and availability in markets across the United States, web data about housing opportunities provide an important alternative—albeit one that demands technical skills that would-be data users may lack. This case study documents the experiences of a collaboration between social and computer scientists focused on using a novel programming-by-demonstration tool for web automation, Helena, to inform rental housing policy and inequalities in the United States. While this project was initially focused on collecting housing ads from a single site within the Seattle area, the capacity to scale our project to new sources and locations afforded by Helena’s human-centered design allowed a team of social scientists to progress to scraping data across the country and multiple platforms. Using this project as a case study, we discuss a.) important programming and research challenges that were encountered and b.) how Helena’s design helped us overcome these barriers to using scraped web data in basic research and policy analysis.
