As computational extraction of word uses from large language databases is becoming popular, manual analysis is becoming even more important in order to accumulate useful pieces of information from huge volumes of automatically stored text data. This study therefore addressed standardization of lexical description, and determined a set of standard processes for the use-case analysis and lexical description, clarifying specifications required for lexical description of word use. Furthermore, based on a newly-compiled large-scale Japanese corpus (BCCWJ), statistical analysis for Katakana representation for Japanese native words and ancient words was performed.
