Welcome to the Public Comment Analysis Toolkit Help Wiki¶

The http://pcat.qdap.net/ (PCAT) is a cloud computing platform. It enables efficient and scalable Web-based collaborative text analysis. PCAT uses automation, clustering, search, meta data filters, peer networks, credentials, an internal architecture for evaluation, and a streamlined annotation work flow to improve the quality of human judgments about text. This initial version of the system is specifically tailored to handle many forms of public comments submitted to US federal agencies during regulatory rulemaking and related public comment-generating activities. PCAT can ingest bulk downloads from the Federal Docket Management System (FDMS), as well as from email servers, survey platforms, and a wide variety of online social media. Watch the "What is PCAT" Webcast to learn more.

Though it was developed for public comments, PCAT is in fact a customizable platform for accurate, reliable and valid classification of any digitized text collection. Single users, expert teams, and wider crowd-sourced groups can browse, search, sift, sort, annotate and report on large collections of text data. In PCAT, the owner of the data (the person who uploads it) has complete control over who in the system can see or work with any particular archive or dataset. The same is true of every aspect of an individual user's credentials. Each PCAT user decides whether and to what extent to be a part of PCAT's public Directory of Peers. The goal of the directory is to create a network of expert and lay users who can collaborate to share data, findings and annotations. We strongly encourage you to upload a picture and your personal and professional credentials so that other users in the system can find you to form a peer network. Open, transparent and re-usable annotations are the end goal.
