Within the last years tm has gained interest from a variety of researchers and users of different backgrounds. In an attempt to inform new users about existing tm applications this site aims to provide (an incomplete alphabetical) list of tm users and their comments. Known users range from research institutes over companies to individuals.

If you use tm and feel comfortable please contact us (feinerer at logic dot at) and send us your feedback! If you want to be included in this list, please provide information on your tm use case and/or comments and who you are (name, affiliation, academics/company/private use).

• Joan-Josep Vallbé (Universitat de Barcelona, Spain) says:

  I am currently finishing my PhD thesis in Political Science at the University of Barcelona and at the Institute of Law and Technology (UAB), and I've found your tm R package really useful for some of the operations I must carry out on text corpora. In particular, my thesis tackles decision-making processes within organizational environments and the tm package has proved really helpful when analyzing text regarding decision-making processes.

• Johannes Liegl (Technische Universität Graz, Austria) says:

  For my PhD studies I was experimenting with topic classification using support vector machines in R. I used the tm-package to bring the input corpora in the adequate format for SVM training/testing. I found the tm-package really easy to use (thanks to the excellent documentation) and very versatile (due to the possibility to extend it with custom functions). The combination of R and the tm-package made me really feel like I was having my fingers directly on the data. Thank you Ingo Feinerer for creating such a nice package.

• Jason Miller (Intel, USA) says:

  Thank you for making this brilliant tool! I am a big fan. I've found tm to be an exciting – perhaps the MOST exciting – package in R for application to economics, market research, and IT research.

• Matteo Romanello (King's College London, United Kingdom) says:

  I'm using your great package TM for R in the framework of my PhD project.

  I'm working on the topic of semantic information extraction from Classics (i.e. Greek and Latin) journal papers.

No other lexical analysis software would have made possible combining those different approaches.
