We mainly discover topic models on two types of data: Federal Open Market Committee (FOMC) meeting transcripts, and Congressional Hearnings. Please find the results at http://www.cs.cornell.edu/~luwang/polinformatics/Topic_Discovery.zip.
We generate 13 queries based on the Wikipedia page for Financial crisis of 2007-08 . The original queries and their expanded version can be found at http://www.cs.cornell.edu/~luwang/polinformatics/queryPhrases.txt .
Here we list the top 1000 snippets retrieved for each query, and the corresponding 1000-word summary. For the summary file, we also indicate the source (i.e. which document the sentence is extracted from) and speaker role when the information is available.
