We offer two language extension packs, the first one supports German, French and Russian texts. The second one supports Chinese, Japanese and Korean texts. Like the core module, these modules combine an algorithmic and a dictionary approach. The quality of these language packs has been checked by native speakers and resulted in an F-score between 0.8 and 0.9.
With this extension pack, you can extract inorganics, metal organics (formulas and names) and polymers. It is often not possible to create a clear structure for these substances. In these cases we offer various output formats, e.g. the structure of monomers in the case of polymers, and molecular formulas or element systems for inorganic substances.
