2003.10.8 Updated

The EDR Electronic Dictionary is renewed.

On October 1, 2003, revised versions of dictionaries, mainly the Japanese Word Dictionary and the Concept Dictionary, were released. In these revised versions, unknown words from recent newspaper articles and the existing EDR Japanese Corpus are collected and added. Comparison with the version 2 is as follows:

Newly registered words Approximately 17,000 words
Newly registered concepts Approximately 13,000 concepts

With favor of the Laboratory of Hozumi Tanaka at the Tokyo Institute of Technology, approximately 1,000 sentences with grammatical labels are also included in the Japanese Co-occurrence Dictionary. Please use them too.

The main improvements and expansions from the first version are as follows:

(1) Addition of words (16,914 words)

The number of words added to each part of speech is as follows;

Nouns: 4,608

Proper nouns: 11,800

S-consonant irregular conjugation nouns: 248

Adverbs: 64

Verbs: 61

Adjectives: 12

Modification verbs: 60

Prefixes: 9

Suffixes: 42

Adnouns: 7

Conjunctions: 1

Exclamations: 2

From the fact that time has been passed since the first version of the EDR Dictionary was issued, unknown words are extracted from the valuation results of the dictionary and selected terms from them are added.
And, proper names are added based upon users’ voices saying that the collection of proper names is not enough. In regards of proper names, the classification codes (such as names of persons, places, and organizations) which have been used from second version are specified in the usage fields. If necessary, please use these useful remarks in you evaluations. Especially for names of companies, they are collected into another independent file (JWC.DOC). In the second version, names of companies were included in the dictionary itself. However, it is now made separately from the dictionary because names of companies tend to be changed more often. The specifications inside the file are the same as the dictionary.
Like the case in names of companies, your suggestions and opinions in regards of the way to organize proper names will be very helpful for us.
