Rootvole

For general processing of voice queries we developed a text parsing library named 'Rootvole' that can be used to match
text with semantic concepts.
The algorithm was implemented in Java and can be described as a form of a parsing expression grammar, where we generate the expressions to be detected beforehand by regular expressions and store them in a vocabulary.
The central class is the parser class, which is instantiated as a series of vocabularies, simple text lists that describe tokens and synonyms, and value descriptors.
It's meant as a lightweight alternative to "real" NLP (natural language processing).
