Sections below describe how to get Lexicoder, the Lexicoder Sentiment Dictionary and some related topic dictionaries, Supporting Files useful for those learning how to use Lexicoder with R, and additional files and links useful for anyone downloading and reformatting content for use with Lexicoder, or other automated content-analytic software.
Lexicoder 2.0 was freely available upon request to academic researchers from summer 2009 to summer 2015. As of August 2015, we have replaced the old software with Lexicoder 3.0. The new software is more reliable, it includes a greater number of functions, and it can deal with larger bodies of data. The interaface is very different, however: 2.0 was accessible only through a basic Java-based interface; 3.0 is designed to be accessible through R (and eventually STATA), and from the Command Line.

Please note that requests should include an email address at an academic institution. Users who have already been using Lexicoder 2.0 should fill out the form again to recieve the newest version. Shortly after recieving the form, we will send you Lexicoder and associated files by email. The Lexicoder manual and practise datasets are available separately, below.

Like Lexicoder software, the LSD has been freely available upon request to academic researchers from fall 2011. As of August 2015, we have updated the format of the LSD so that it works with Lexicoder 3.0. Users who have already been using the Lexicoder 2.0-formatting version of the LSD should fill out this form again to recieve the newest version.
For this most current version of the LSD, please fill out our request form by clicking here. Users will be provided with the dictionary in Lexicoder format, easily adapted to other software as well.
Please note that requests should include an email address at an academic institution. Shortly after recieving the form, we will send you the LSD and associated files by email. The LSD manual will be included in the distributed zip file.

A French-language version of the LSD is also available, produced by Duval and Petry, here.
Note that the quanteda package in R has a very straightforward implementation of the LSD. And the pre-processors to improve the performance of the LSD have been adapted for implementation in R, by Emily Luxon (University of Michigan at Dearborn), and can be downloaded as a single R script by clicking here.
We are currently working on a series of topic dictionaries, aimed at capturing topics in news content, legislative debates, and policy documents. Our goal to is to capture Major Topic codes from the comparative Policy Agendas project, in multiple languages. Currently, we are working on dictionaries in English, Dutch, and Hebrew, in conjunction with the INFOPOL project.
Development of these dictionaries is ongoing, but we welcome any and all testers and contributors. (Indeed, our hope is that we can crowd-source the development of topic dictionaries.) The current versions of English and Dutch dictionaries can be downloaded below; the most recent tests of these dictionaries are described in this paper. If you are interested in adding to our work on topic coding, please do let us know at firstname.lastname@example.org.

And example workflow in R. This zip file includes an R script file, sample dataset and dictionary files. It is intended to provide some simple examples of how to integrate Lexicoder into a R-based content analysis.
