libchemicaltagger-java - 1.6.2-4 main

ChemicalTagger parser is a medium-depth, phrase-based semantic NLP tool for the
language of chemical experiments. Tagging is based on a modular architecture
and uses a combination of OSCAR, domain-specific regex and English taggers to
identify parts-of-speech. The ANTLR grammar is used to structure this into
tree-based phrases.
