Welcome to the Coding Analysis Toolkit Help Wiki Help Wiki

The Coding Analysis Toolkit (CAT) is a free, open source, cloud computing platform built on Microsoft's ASP.NET technology. CAT enables efficient, transparent, reliable, valid and scalable Web-based collaborative manual text categorization and analysis. As a free, Web-based system, CAT creates the opportunity for low-cost replication or examination of coding choices. CAT is also an excellent training tool for teaching students about the role of human subjectivity in recording observations about text.

CAT is a service of the Qualitative Data Analysis Program (QDAP), which is hosted by the University Center for Social and Urban Research, at the University of Pittsburgh, and QDAP-UMass, in the College of Social and Behavioral Sciences, at the University of Massachusetts Amherst. CAT was the 2008 winner of the "Best Research Software" award from the organized section on Information Technology & Politics in the American Political Science Association.
