Language and language processing technologies are an important basis for research in the field of information science. The development of linguistic databases, such as electronic dictionaries (machine-readable/tractable dictionaries), contributes to the development of stable language processing technologies. The information research potential of the electronic dictionary greatly broadens and expands the field of information science. The fields of knowledge processing and information science greatly overlap. The building of very large knowledge bases, which will fully stabilize knowledge processing technologies, can be most effectively approached by considering/utilizing research in linguistic knowledge in combination with research in the technology of language processing. This paper will discuss the EDR Electronic Dictionary in relation to the development of very large knowledge bases.
