摘要

In 1998, millions of internal tobacco industry documents were released onto the Internet. Access to these documents led to discoveries about how the tobacco industry behaves and their motivations. The utilization of the internal tobacco industry documents has changed public health. However, along with this access came problems in accessing and utilizing the documents to their maximum capacity.;The aim of this dissertation is to study (1) who uses the internal tobacco industry documents; (2) how they are used; (3) problems using the documents; (4) methods to improve searching. These questions are examined using both quantitative and qualitative methods via a survey and a usability study of the Legacy Tobacco Documents Library. One of the major findings of the study is that teachers, lawyers, and public health advocates are under-utilizing searching of the internal tobacco industry documents.;Then I explored researching the tobacco industry documents using different text mining algorithms. Using SAS Text Miner(TM) and Leximancer, I compared the results of concepts derived from the documents to a gold standard. The results showed that similar concepts were obtained using Leximancer when comparing it to a gold standard. I concluded that text mining the tobacco industry documents may be a useful technique for researchers.;There are many different reasons for searching the internal tobacco industry documents. The development of new user interfaces may help to encourage different user groups to continue to utilize this tremendous resource.
