框架是政治传播的核心概念，也是一种强有力的政治工具。理解什么样的框架被用来确定特定的问题，以及框架随时间的演变所证明的一般模式是非常重要的。这也是一个严峻的挑战，由于文本数据量，语言的动态性质，以及适用框架的差异跨问题（例如，死刑辩论的“无罪”框架不用于讨论禁烟令）。我们描述了一个项目，从两个方面推进框架研究方法。首先，我们正在开发一个统一的编码方案，用于跨问题的内容分析，无罪）嵌套在横切问题（例如，公平）;我们正在验证这个编码方案，将其应用于过去23年来美国移民、同性婚姻和吸烟/烟草的新闻报道。其次，我们正在开发半自动和自动框架发现的方法，旨在复制手动编码和隔离人类检查可能不容易看到的框架进化模式。我们的目标是采用策略，充分了解现有的工作在自然语言处理，但量身定制的特殊需求和专业的政治传播学者的敏感性。
Framing is a central concept in political communication and a powerful political tool. Understanding what frames are used to dene specic issues and also what general patterns are evidenced by the evolution of frames over time is hugely important. It is also a serious challenge, thanks to the volume of text data, the dynamic nature of language, and the variance in applicable frames across issues (e.g., the ‘innocence’ frame of the death penalty debate is not used in discussing smoking bans). We describe a project that advances framing research methodology in two ways. First, we are developing a unied coding scheme for content analysis across issues, whereby issue-specic frames (e.g., innocence) are nested within high-level dimensions (or frame types) that cross-cut issues (e.g., fairness); we are validating this coding scheme by applying it to news coverage of immigration, same-sex marriage, and smoking/tobacco in the United States over the course of the past twenty-three years. Second, we are developing methods for semi-automated and automated frame discovery aimed at both replicating manual coding and isolating patterns of frame evolution that might not be readily visible to human inspection. Our goal is to employ strategies heavily informed by existing work in natural language processing, but tailored to the specic needs and professional sensibilities of political communications scholars.
