Scaling Policy Preferences from Coded Political Texts
Scholars wanting to estimate substantive quantities of interest, for example policy positions, from political texts typically apply a coding scheme to discrete text units such as words or sentences. Scales of policy positions, for example a left-right scale of economic policy, are typically built from the relative frequencies of text units coded into different categories. In this paper we reexa...
متن کاملScaling Policy Positions From Coded Units of Political Texts∗
Applying a coding scheme to discrete text units has long been the most common method for estimating substantive quantities of interest about the authors of these texts, whether for political, social, economic, or other substantive reasons. In political analysis, researchers typically build scales of policy positions from the relative frequencies of text units coded as left versus right policy c...

D eriving reliable and valid estimates of the policy positions of key actors is fundamental to the analysis of political competition. Various systematic methods have been used to do this, including surveys of voters, politicians, and political scientists, and the content analysis of policy documents. Each method has advantages and disadvantages but, for both theoretical and pragmatic reasons, p...
متن کاملUnsupervised Cross-Lingual Scaling of Political Texts
Political text scaling aims to linearly order parties and politicians across political dimensions (e.g., left-to-right ideology) based on textual content (e.g., politician speeches or party manifestos). Existing models scale texts based on relative word usage and cannot be used for cross-lingual analyses. Additionally, there is little quantitative evidence that the output of these models correl...
متن کاملExtracting Policy Positions from Political Texts Using Words as Data
We present a new way of extracting policy positions from political texts that treats texts not as discourses to be understood and interpreted but rather, as data in the form of words. We compare this approach to previous methods of text analysis and use it to replicate published estimates of the policy positions of political parties in Britain and Ireland, on both economic and social policy dim...
