The tool combines regular expressions containing variables with propositional logic to form search patterns which identify lemmas tagged with their paradigm class. Furthermore, we describe the underlying algorithm of the tool and suggest a method for developing a morphological lexicon. The...

متن کاملLactic acid production from agricultural resources as cheap raw materials.
Agricultural resources such as barley, wheat, and corn were hydrolyzed by commercial amylolytic enzymes and fermented into lactic acid by Enterococcus faecalis RKY1. Although no additional nutrients were supplemented to those resources, lactic acid productivities were obtained at >0.8 g/l h from barley and wheat. When 200 g/l of whole wheat flour was hydrolyzed by amylolytic enzymes after the p...
