eRulemaking: Text Mining Techniques for Large Public Comment Databases

Citizens and government administrators need a variety of navigation aids and text analysis tools to help them cope with the hundreds of thousands of emails received as a result of organized letter-writing campaigns about proposed government regulations. These aids and tools include duplicate- and near-duplicate detection, automatic construction of browsing hierarchies, and tools that identify stakeholder communities mentioned in comment texts. The underlying technologies are primarily Information Retrieval, Text Datamining, and simple forms of Natural Language Processing. These tools are being used by the US Fish and Wildlife Service to analyze comments being submitted about the proposed rule to list the polar bear as a threatened species, and the proposed rule to remove the gray wolf as an endangered species.
