A Dynamic State-Space Model of Coded Political Texts
This article presents a new method of reconstructing actors’ political positions from coded political texts. It is based on a model that combines a dynamic perspective on actors’ political positions with a probabilistic account of how these positions are translated into emphases of policy topics in political texts. In the article it is shown how model parameters can be estimated based on a maxi...
متن کاملScaling 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...

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...
متن کاملDynamic System-optimal Traffic Assignment Using a State Space Model’
Abstract-We propose a new mathematical formulation for the problem of optimal traffic assignment in dynamic networks with multiple origins and destinations. This problem is motivated by route guidance issues that arise in an Intelligent Vehicle-Highway Systems (IVHS) environment. We assume that the network is subject to known time-varying demands for travel between its origins and destinations ...
