Lexicoder is Java-based, multi-platform software for automated content analysis. The software will be freely available for academic use, alongside the Lexicoder Sentiment Dictionary (LSD) here.
Still in the testing stage, Lexiarchiver software gathers tweets in real-time for academic analysis. The system will be subscriptioin based (to cover server costs). Data will be downloadable in tab-delimited format, ready for use with Lexicoder, but with any other content analytic or statistical software as well.
