PRISMA: Protocol Inspection and State Machine Analysis
The PRISMA package is capable of loading and processing huge text
corpora processed with the sally toolbox (http://www.mlsec.org/sally/).
sally acts as a very fast preprocessor which splits the text files into
tokens or n-grams. These output files can then be read with the PRISMA
package which applies testing-based token selection and has some
replicate-aware, highly tuned non-negative matrix factorization and
principal component analysis implementation which allows the processing of
very big data sets even on desktop machines.
